985 24337-R02 General description AQUA Blue

Application
Conversion of seawater into fresh water by vacuum distillation for the supply of high quality fresh
water for domestic and process utilization. For installation on ships, rigs and remote onshore
locations.

The AQUA Blue is designed for automatic operation with continuous control of high quality fresh
water with a maximum salinity of 2 ppm when design conditions are met.

Heating media is waste heat, jacket water, steam or by a Hot Water Loop.
At all time the Alfa Laval AQUA Blue fresh water generator secure pure fresh water onboard and
replacement of bunker water.

Capacity
The AQUA Blue covers a capacity range from 2 to 60 m3/24hr, depending on the heating medium
temperature, flow and seawater temperature. The capacities shown below are at 32ºC seawater
temperature.

Working principle
Picture 1

The feed water to be evaporated is taken

from the sea cooling water outlet of the
condenser. It enters the evaporator where it
evaporates at about 40–60°C as it passes
between the plates heated by the heating
medium.
The evaporating temperature corresponds
to a vacuum of 85–95%, maintained by the
brine/air ejector. The vapours generated
pass through a separation section where any
drops of seawater entrained are removed
and fall due to gravity to the brine sump at
the bottom of the titanium plate stack. The
clean fresh water vapours continue to the
condenser section, where they condense
into fresh water as they pass between the
cold plates cooled by the sea cooling water.

Picture 2
Picture 3

Basic equipment
Titanium plate heat exchanger
Sea- and feed water pipes in Duplex stainless steel.
The freshwater generator is equipped for hot water heating and with a combined condenser and
ejector water system. Furthermore the freshwater generator is equipped with dump valve including
return pipe, water clock, automatic feed water regulator, combined brine/air ejector, instruments,
fresh water pump with electric motor, internal piping and frame parts.

9.2.7.1 General description, Hot Water Loop (HWL)

Application

Heating and circulation of jacket water to the freshwater generator.

Ensures a constant temperature and jacket water flow, even when
the engine is not running. A blinded connection in module makes it
usable as pre-heater for the engine e.g. when the ship is in
harbour.

The HWL is available in 4 sizes covering a capacity range from 7

to 100 m3/24h of fresh water:
HWL 7-20: 7-20 m3/24h
HWL 20-35: 20-35 m3/24h
HWL 35-60: 35-60 m3/24h
HWL 60-100: 60-100 m3/24h

Working principle

A partial flow of the jacket water (engine cooling water) is led to

the heat exchanger.
To achieve the required jacket water temperature, the partial flow
is heated by steam above the temperature set point. By this the
temperature of the mixed partial and main flow is correct and
equal to set point. The amount of steam is regulated by a steam
valve controlled by thermostat or a digital temperature regulator
mounted after the mixing point.
A hot water pump is ensuring a constant flow and makes
recirculation possible during engine low-load or stop. For pre-
heater purpose, there is a blinded connection at the inlet to heat
exchanger. The hot water pump is not running, only the engine
cooling water pump. The outlet connection is to be mounted by
customer after the HWL.

Basic equipment

Stainless steel heat exchanger.

Steam valve controlled by a thermostat (HWL 7-20) or a
digital temperature regulator.
Hot water pump (cast iron) with electric motor.
Furthermore the HWL is equipped with regulating valves, water
trap, internal piping, and bed frame.

AQUA Blue type HW

3.1 Working principle

The combined brine/air ejector driven by the cooling water creates the necessary
vacuum in order to lower the evaporation temperature of the feed water.

The feed water is introduced into the evaporator section through an orifice, and is dis-
tributed into every second plate channel (evaporation channels)

System Description – AQUA Blue type HW 6 985 24995 R01 – June 18, 2014
Pages 105
 .

The hot water is distributed into the remaining channels, thus transferring its heat to the
feed water in the evaporation channels.
Having reached boiling temperature – which is lower than atmospheric pressure – the
feed water undergoes a partial evaporation and generates a mixture of vapour and
brine. The brine is separated from the vapour and extracted by the combined brine/air
ejector.

System Description – AQUA Blue type HW 7 985 24995 R01 – June 18, 2014
Pages 106
 Having passed a separation section the vapour enters every second plate channel in the
condenser section. The cooling water supplied distributes itself into the remaining
channels, thus absorbing the heat being transferred from the condensing vapour. The
produced fresh water is extracted by the freshwater pump and pumped to the remaining
freshwater system or fresh water tank.

3.2 Freshwater Quality

To continuously check the quality of the produced fresh water, a salinity meter is pro-
vided together with an electrode unit fitted on the freshwater pump delivery side.

If the salinity of the produced fresh water exceeds a chosen maximum value, the dump
valve and alarm are activated to automatically dump the produced water back to the
freshwater generator.

System Description – AQUA Blue type HW 8 985 24995 R01 – June 18, 2014
Pages 107
3.3 Main Components
The freshwater generator consists of the following main components:

1. Production unit 
The production unit consists of Titanium plates encased in a coated steel plate
frame. The plates include the tree main functions. Evaporation, separation and
condensation. Evaporation in the lower part, separation in the middle and conden-
sation in the upper part.

2. Combined brine/air ejector 

The ejector extracts brine and non condensable gases from the process.

3. Freshwater pump
The freshwater pump is a single-stage centrifugal pump. The freshwater pump
extracts the produced fresh water after condensing, and pumps the freshwater-
system or tank.

4. Salinometer
The salinometer continuously measures the salinity of the produced freshwater. At
too high salinity the produced freshwater is automatically diverted back to the
freshwater generator. The alarm set point is adjustable (the salinometer is mounted
in the control panel).

System Description – AQUA Blue type HW 9 985 24995 R01 – June 18, 2014
Pages 108
 5. Ejector pump (Optional)
The ejector pump is a single-stage centrifugal pump. This pump supplies the con-
denser with the necessary seawater and the brine/air ejector with jet water. A part
of the seawater is used as feed water for evaporation.

6. Control panel
Contains motor starters with thermal overload relays and running lights for each
pump, salinometer and voltage free NC / NO contacts for remote alarm, further the
Control panel is prepared for remote start/stop of the pumps.

4 Storage

4.1 Storage
Unless otherwise agreed, Alfa Laval delivers the equipment ready to be put in service
upon arrival and after installation.
However, should it be necessary to store equipment for a longer period (1 month or
more), certain precautions should be made in order to protect and prevent unnecessary
wear of the equipment.
The best solution is often to leave the equipment in the packing until it's time for instal-
lation. In this case Alfa Laval should be informed, in order that proper preparation can
be done prior to packing.
Preferably, the equipment should be stored inside in a vibration free area at a temper-
ature around 15 to 45°C (59 to 113°F) and humidity around 70%

NOTE!.
There should ABSOLUTELY NOT be any OZONE PRODUCING
equipment in the room, like operating electric motors or arc-welding,
since ozone destroys many rubber materials.

Do not store organic solvents or acids in the room.

Avoid heat and ultraviolet radiation.

If the equipment must be stored outdoor, the precautions mentioned above should be
taken as far as practical. The need for protection against the climate etc. is of course
even more important in this case.

Pages 117
6.1 Start up and operation procedure

CAUTION!
In order to avoid malfunctions, we recommend following the pipe
dimensions indicated in the Flow chart drawing.

1. Open valves on the suction and discharge side of the ejector pump PU-SC-01.

2. Open overboard valve for combined brine/air ejector discharge.

3. Switch on power supply.

4. Close air Bleed valve VA-E1-01 on air suction line.

5. Start Ejector Pump PU-SC-01 and create vacuum min 85%.

CAUTION!
Do not run the Ejector Pump with closed SW overboard valve, this
action can cause damage to instruments and unit.

Adjust the pressure at th e ejector inlet to be in the green working area, between 3,0
and 4,0 Barg.

Figure 6-1. Push ejector pump Start button, and switch on salinometer.

Operating Instructions - AQUA Blue type HW 19 985 24995 R01 – June 18, 2014
Pages 118
Figure 6-2. Keep inlet SW pressure in the green range.

• Secure that feed water treatment has started with the ejector pump.

• Check feed water treatment and adjust to required dosing rate.

Figure 6-3. Open for feed water treatment and adjust to app. 70 (see table in Part 10.5.3
Calculating Chemical solution for dosing amount) and keep the other button at 100%
as on the picture.

6. Open HW on/off outlet valve 50% and HW on/off inlet valve 100% (Yard supply)
This will secure that the HW by-pass valve adjustment is more optimal.

7. Close partly the HW by-pass valve (Yard supply) 

This will send HW to the unit starting it up slowly by only sending a small part of
the HW to the unit.

Pages 119
 NOTE!
The maximum freshwater pump discharge pressure can be found in the
attached technical data.

8. Start the freshwater pump PU-FR-01

Distillate production is started when water can be seen in the flow sight glass at
the suction pipe to the distillate pump, and the level is increasing. 

When the salinity is below the set point, check the production rate and compare it
with the design production rate.

 9. Adjusting freshwater production

Adjust SW by-pass valve:
Keep condenser outlet temperature in green working area, by adjusting the SW
by-pass valve following the illustrations on the thermometer.

Running to warm will decrease production and increase risk of scaling.


Running to cold will increase production and increase risk of high salinity in dis-
tillate, and risk of scaling by to high production rates.

10. Adjust HW by-pass valve:

Decreasing HW flow will result in lower production, lower boiling temperature
and slightly lower salinities.
HW flow will result in higher production, higher boiling temperature and higher
salinity.
Running the unit at higher production rates than design rate, will result in
higher brine salinities and higher scale rates than normal. The freshwater
salinity level will be higher, and unstable utilities can cause high salinity
dumping and alarms.

CAUTION!
Keep production at design rate: Higher production rate than design,
increases risk of high salinity and scaling

11. Air bleed valve VA-E1-01 

Vacuum should be released at stand still by opening the air bleed valve. Check
that this valve is closed in running conditions.

In very cold seawater and at very high production rates it could be needed also to

Operating Instructions - AQUA Blue type HW 22 985 24995 R01 – June 18, 2014
Pages 121
 open the air bleed valve to get the design production and desired salinity level.
This action will increase the boiling temperature and lower the production rate.
Before performing this action check that the SW by-pass valve is fully open.

Figure 6-6. Air bleed valve. 

Open this partly in very cold seawater operation.

This operation will send air into the condenser and vacuum system, and secure that
the capacity is not increasing, and the salinity kept low.

The freshwater temperature will decrease at open air bleed valve.

6.2 Daily operation

• During normal operation it is strongly recommended to make daily logs (by filling
in the test sheet enclosed in the manual).

• If production rates are too high or too low then adjust the SW and/or HW by-pass
valves.

• If production rates are below the design and the unit is operated with design utili-
ties (temperature & flow), then clean the unit manually or by CIP.

• Never run the unit without an anti-scale chemical. Secure correct dosing rates by
keeping a log of the chemical consumptions.

6.3 Adjustment of Hot Water Flow

Please refer to "FWG Order Specification"
In order to help adjusting to the specified flow of hot water to the freshwater generator
below calculations can be done.

Operating Instructions - AQUA Blue type HW 23 985 24995 R01 – June 18, 2014
Pages 122
 It is necessary to adjust the bypass valve until desired flow is achieved.
The flow can be calculated as follows:

3
K JW  Cap.m /24h
M JW = ----------------------------------------------  m 3  h 
t JW

Where:
MJW = Hot water flow. [m³/h]
KJW = Constant = 25.6
tJW = Difference in temperature of hot water in and out. [°C]
Cap.m³/24h = Freshwater production in 24 hours, i.e. production in 5 min. 
times 288. [m³]
Example: Cap. m³/24h = 15 m³
tJW =18.4°C
25.6  15 3
M JW = ---------------------- = 20.9 m /h
18.4

Alternatively adjust the by-pass valve until the fresh water production is according to
design. If to high production, salinity in the product can be to high.

6.4 Adjustment of Sea Cooling Water

The sea cooling water flow is correct, when the pressure at the inlet side of the com-
bined air/brine ejector (PI-ES-01) is between 3.0 and 4.0 Barg (42.7 and 56.9 Psig).

6.5 Stopping the Plant

1. Close hot water inlet and outlet on/off valves (Yard supply).

2. Stop the freshwater pump PU-FR-01 and close valve to storage tank (Yard sup-
ply).

3. Let the ejector pump PU-SC-01 run for approx. 5 minutes to cool down the unit.
Then stop the pump.

4. Switch off power supply.

5. Open air bleed valve VA-E1-01 on air suction line. It is important to release the
vacuum at standstill.

Operating Instructions - AQUA Blue type HW 24 985 24995 R01 – June 18, 2014

8.1 Why you need to perform regular maintenance

duties
Regular maintenance of the plant will improve performance and availability.
The maintenance schedule on the following pages will tell you how often service
should be performed on the main components.
As the actual operating conditions of the plant are of major influence on the life time,
the overhaul dates are not obligatory but only recommended intervals.
When the plant has been in operation for a longer period of time and experience has
been established as to the actual performance, it will be possible to adapt the mainte-
nance schedule.
For service on minor components please refer to component instructions.

11. The condenser section is pressure tested by starting the ejector pump and letting
sea water circulate through the condenser section.

12. Look for leakages in sight glass at fresh water outlet

NOTE!
If the gaskets are correct positioned the rubber indicators will be visi-
ble on every second plates on the right respectively left hand side.
If the plates are correctly assembled, the edges form a "honeycomb"
pattern.

CAUTION!
Before starting the combined ejector/cooling water pump, the feed
water must be sealed off.

8.4 Renewal of Plate Heat Exchanger Gaskets

8.4.1 Removal of Old Gaskets

Pull the old gaskets out of groove.
If the gasket cannot come off directly, heat the back of the gasket groove with a hot-air
blower or butane gas burner.
Pay attention not to overheat the plates.
You will obtain a suitable temperature, if the flame is held 10 to 15 cm behind the plate.

WARNING!
DO NOT use acetylene gas

 8.4.2 Cleaning
Charred or loose glue and rubber remains must be removed.
Clean the gasket groove with a clean cloth, dipped in a solvent (acetone, methyl ethyl
ketone, trichloroethylene etc.).

WARNING!
Be careful when handling these solvents, as they may be hazardous to
your health. Observe suppliers' instructions.

Gaskets, that have loosened, can be glued on. Clean gasket groove carefully. Then
clean the loose part of the gasket with emery cloth. Finally clean groove and gasket
with a solvent, and add glue.

8.4.3 Preparation of new Gaskets

Dry new gaskets with a clean cloth that has been slightly moistened with a solvent.

8.4.4 Fitting new Gaskets

1. Apply a thin layer of glue to both gasket and groove.

2. Let the glue dry for 10-15 minutes.

3. Fit new gasket into groove.

4. Gaskets may sometimes be slightly short or long.

5. Short gaskets should be stretched before being fitted into the groove.

6. Long gaskets should be fitted into the grooves at the plate ends first and then grad-
ually be pushed into the groove towards the middle.

7. If necessary, tape gasket into groove.

8. Assemble plate pack according to attached assembly scheme.

10 Chemical Dosing of Scale
Control Chemicals

10.0 Prevention of Scaling

During evaporation of seawater there is always a risk of scaling on the heating surfaces.
Scale will lead to a reduction of the K-values (Heat Transfer Value) on the heating sur-
face and decrease the freshwater production. This will demand extensive cleaning.
Without correct operation of the Freshwater generator as well as chemical treatment of
the feed water before it enters the AQUA unit, solid salts will form scales. The degree
of deposit of scales (solid salts) depends on the concentration of calcium, magnesium,
bicarbonates and sulphate in the seawater. At certain temperatures calcium carbonates,
magnesium hydroxides and calcium sulphate will solidify and deposit on any surface
they are in contact with over a sufficiently long period of time.
Scaling may occur. In order to effectively prevent scaling the operators must be aware
of the various factors influencing scale formations

10.1 Feed Water Ratio

The feed water ratio is an extremely important factor. It is defined by the relationship
between the feed water amount fed into the plant and the produced amount of 
freshwater.
Mf
Feed Water Ratio = --------
Md

Mf = total flow of feed water

Md = total flow of freshwater
If the feed water ratio is reduced, the concentration will rise in the plant subsequently
resulting in scale formations.

NOTE!
The AQUA is designed to a feed water ratio at 3.25.

Chemical Dosing of Scale Control Chemicals 36 985 24995 R01 – June 18, 2014
Pages 135
 Two things may shift the feed water ratio: first of all direct adjustment of the feed
water system, and secondly exceeding the maximum freshwater production laid out for
the plant.
The operators must observe the following rules at all times.

CAUTION!
DO NOT adjust spring loaded valve at the feed water system.
The feed water pressure at PI-ES-01 shall be minimum 3.0 (42.7 Psig)
and maximum 5.0 Barg (72.5 Psig)

10.2 Evaporating Temperature

Another factor influencing scale formation is the evaporating temperature. Tempera-
tures higher than laid out by Alfa Laval will increase the scaling risk.

10.3 Operational Notes

10.3.1 Normal Operation Conditions

It is important that operating personnel become familiar with normal operating condi-
tions so that deviations from the norm can be recognised quickly and dealt with
promptly. The Table in Technical Data lists the approximate readings that should be
obtained during normal operation of the unit. Most of these indications will be found
on the central instrument.

10.3.2 Maintaining Distillate Output

The normal feed water treatment will keep the scale of evaporator to a minimum;
though not prevent it completely, over time scale will accumulate. The length of this
period depends both of the operation of the plant as well as the quality of the seawater.
If the temperature of the incoming feed water is held constant at the normal value, the
production of the unit will gradually decrease as scale accumulates on the plate sur-
faces. Eventually the scale will have to be removed by acid cleaning.
The rate of scale deposition depends on many factors, including:

• Chemical composition of the feed water

• Degree of attention to feed water treatment

It is therefore good practice to shut down the unit periodically for several hours to
inspect the plate surfaces for scale. Experience will dictate the time interval between

Chemical Dosing of Scale Control Chemicals 37 985 24995 R01 – June 18, 2014
Pages 136
 inspections. Never depend upon visual inspection alone, but rather, the unit should be
opened and samples of scale taken for measurement of thickness, in accordance with
cleaning the unit.
Scaling on plates leads to an increase of the total plant temperature difference. The
increased temperature difference will lead to a higher evaporation temperature which
will increase the risk of scale formation.
Scaling may occur. In order to effectively prevent scaling the operators must be aware
of the various factors influencing scale formations.

10.4 Chemical Dosage

In order to control scale formations on the heating surfaces and continuously ensure
long operation periods without cleaning the Freshwater generator, it is absolutely nec-
essary to dose scale control chemicals to the feed water.
Calcium carbonate and magnesium hydroxides are soft or alkaline scales and can rel-
atively easy be dissolved with acid solutions. They are primarily formed at tempera-
tures above 45°C. Since the AQUA typically is operated at temperatures above 45°C,
scale becomes a real issue, which needs to be dealt with by adding anti scalant chemi-
cals.
It is also very important that the scale inhibitor used is effective at the evaporation tem-
perature and at the same time effective at a feed water ratio factor 3.25.
The operators must follow the instructions for chemical dosing very carefully.

CAUTION!
If the freshwater generator is operated at boiling temperatures above
45°C (113°F) without chemicals, frequent cleaning of the evaporator
will be necessary.

NOTE!
We recommend that you do not operate the freshwater generator with-
out recommended chemical dosage at boiling temperatures above
45°C (113 °F). Even at lower temperatures it can be recommended.

10.4.1 Scale Inhibitor Dosage Equipment for Feed Water

Mix thoroughly to ensure a homogenous blend when adding chemicals to water.

Chemical Dosing of Scale Control Chemicals 38 985 24995 R01 – June 18, 2014
Pages 137
 Use a fully soluble scale inhibitor, e.g. on polymer basis. The following product can be
recommended:
Alpacon Altreat 400
Should other antiscale chemicals be used, the user will be fully responsible concerning
its efficiency in scale control and its compatibility with the plant and equipment.
Should this selection of chemical cause any damage to any part of the plant or result in
insufficient control of the formation of scale in the plant, then such cases will not be
covered under Alfa Laval's warranty obligations.
Alfa Laval refrains from discussing or commenting on other brands of antiscale chem-
ical, as we find the responsibility for the applicability and use of a certain brand chem-
ical should be the chemical supplier's.

 10.4.2 Safety Precautions with the use of Chemicals

WARNING!
The operators must follow the instructions for chemical dosing given
by the chemical supplier carefully.

USE eye protection and gloves. Avoid direct skin contact, eye contact
or contact with clothes.

CLEAN empty containers before disposal.

If chemicals are spilled on clothes, rinse with water and dispose off
clothes.

If chemicals are spilled on the floor, rinse with water and suck remain-
ing chemicals off with sand. Clean the spot immediately afterwards.

Scale inhibitor is hazardous, if consumed in a concentrated solution. If

consumed by mistake.
IMMEDIATELY SEEK MEDICAL ATTENTION.

If eyes get in contact with the chemicals, rinse for at least 20 minutes.
IMMEDIATELY SEEK MEDICAL ATTENTION.

WARNING!
Read carefully the safety data sheet before using any chemicals.

10.4.3 Alpacon Altreat 400

Alfa Laval recommends Alpacon Altreat 400, which is an Alfa Laval scale inhibitor
product, for dosing to the feed water.

10.5 Preparation of chemical solution

10.5.1 Anti Scalant type Alpacon Altreat 400

The Alpacon Altreat 400 can be used concentrated or as a solution.
It is necessary to use a solution to the AQUA units as the dosing rate shall be at as high
as practical to secure an even distribution.
The solution is prepared in the mixing tank by dissolving the Alpacon Altreat 400 addi-
tive in fresh water or distillate. The maximum effective life of the solution is one week.
Preparation of quantities of solution for longer periods is therefore not recommended.

10.5.2 Dosing flow calculation

Dosing flow [l/day] = Effective volume [litre] / Filling interval [days]

12.2 Description and specification of

Salinometer type DS-23
The salinometer is used in combination with an electrode that - based on conductivity
- measures and supervises the salinity of produced water.

Salinometer 50 985 24995 R01 – June 18, 2014

Pages 149
 The control device is provided with indication LED's for monitoring the salinity level
and two LED's for alarm purpose. The measuring range as well as the adjustable alarm
range is 0 - 200 ppm (sea salt). The alarm limit can be adjusted by means of the "Alarm
set" buttons on the front panel. The alarm limit is indicated by a flashing LED in the
indication bar. If the salinity level exceeds the alarm limit, the alarm LED's will start
flashing.

12.3 System Startup

During commissioning it is not necessary to carry out any adjustments of the equip-
ment, except setting the alarm limit. When the power is turned on, the salinometer will
perform a self-test. This test will take approximately 5 seconds, after which the unit is
ready for operation.
The electrode measures the conductivity in the water; And besides salts, acidity and
chemicals, particles & dirt in the water can and will also influence this parameter.
Especially during commissioning, startup and longer shutdown periods, the measured
values may be significantly higher than what is found in a chemical test (that only
reacts to plain salt).
The temperature-compensation embedded in the electronics in the electrode needs time
to reach water-temperature and therefore, during start-up and in connection with
sudden changes in temperature, a deviation between measured and actual salinity may
appear momentarily.

Salinometer 51 985 24995 R01 – June 18, 2014

 If a large persisting difference between DS-23 readout and chemical test is found, the
water should be checked for acidity and foreign contaminants like oil and dirt-particles.

12.4 Installation of Salinometer type DS-23

1. Make sure, that the mains supply is secured against overcurrent by an external
fuse (blow-type max.100mA). There are NO fuses in the salinometer.

2. The Salinometer is adapted to operate from 98 to 122V AC 50 60 Hz or 196 to

244V AC 50 60 Hz.

3. Lay the necessary cables and connect them to the female connector.

4. Connect the female into the male connector and test the instrument as described.

NOTE!
The screen must not be connected to ground, but must be routed from
pin 4 on electrode to pin 14 on DS-23.
Grounding will render the measurement invalid, and may cause 
damage to the electrode.

NOTE!
The cable must not be placed together with high powered cables, as
this can cause damage to the gold plating on the electrode.

 NOTE!
The internal alarm relays are shown as in the above position when the
Salinometer is Powered ON with no alarms. If the Salinometer has an
alarm or is without main power supply, the relays will change position.

12.5 User instruction for Salinometer type DS-23

1. Check that the LED "Electrode Disconnected" does not indicate an incorrect con-
nection to the Electrode unit. If the LED is on, the salinometer has found a wrong
connection which is either a short circuit, a disconnected cable or the electrode
unit is defective.

2. Adjust the alarm level to the required level by using the up or down arrows.

3. Be sure that "ALARM ON/OFF" is in the right position.

The salinometer is now ready for use.

If the salinity exceeds the alarm level, the instrument signals an alarm:
1. The alarm LEDs are flashing.

2. The externally connected alarm devices (solenoid valve(s), buzzer, external alarm
system(s) etc. are functioning. The external alarms will be cancelled by pushing
the "ALARM ON/OFF" button, with exception of the solenoid valve. When the
alarms are operative, the green LED lights up.

12.6 Maintenance of Salinometer type DS-23

Always keep the salinometer dry and clean.
The accuracy of the salinometer is very dependent on that the electrodes are kept clean.
The electrodes should be taken out and cleaned at least once a month.
Use only a clean and soft cloth or Q-tip. When cleaning the electrode it is IMPOR-
TANT that the cloth or Q-tip is not polluted by oil or other chemicals. Any type of pol-
lutant will immediately result in an inaccurate measurement of the salinometer.
If the surface of the center pin of the electrode is damaged the electrode needs to be
replaced.

Salinometer 54 985 24995 R01 – June 18, 2014

Pages 153
 NOTE!
Avoid damaging the gold plating. If the gold plating is damaged, the
conductive electrode must be replaced.

The electrode unit is a wear and tear part and the expected lifetime expectancy is
approximately 18 - 24 months.
If the surface of the electrode is damaged it needs to be replaced.

Safety Instructions and Warnings

WARNING

The freshwater generator is not to be operated in polluted water or within

20 miles from the coast

Freshwater must not be produced from polluted water, as the produced water can
be unsuitable for human consumption.

If manuals are translated to local language the unit comply with the EEC Machinery
Directive and EN 292-1/2 standards. For EEC land installations manuals MUST be
available in local language before installing and operating the unit.

The unit also comply with EN 50081-2 and EN 50082-2 “Industry” with regards to the
EMC directive from EEC.

WARNING

Noise hazards
• Use ear protection in noisy environments.

Crush hazards
• Use correct lifting tools.
• Do not work under hanging load.

Burn hazard
• Wear gloves to avoid burns by hot surfaces.

Cut hazards
• Wear gloves to avoid cuts by sharp edges when handling machined
parts.
• Wear helmet to avoid cuts by sharp edges during maintenance of the
equipment.

NOTE

• Max. ambient temperature for the equipment is 50°C (122°F).

• Min. ambient temperature for the equipment is 0°C (32°F).

 Storage/Long Term Standstill

1.0.0 Storage
Unless otherwise agreed, Alfa Laval delivers the equipment ready to be put in ser-
vice upon arrival and after installation.

However, should it be necessary to store equipment for a longer period (1 month or

more), certain precautions should be made in order to protect and prevent unneces-
sary wear of the equipment.

The best solution is often to leave the equipment in the packing until it's time for in-
stallation. In this case Alfa Laval should be informed, in order that proper preparation
can be done prior to packing.

Preferably, the equipment should be stored inside in a vibration free area at a tem-
perature around 15 to 20 deg.C (59 to 68 deg.F) and humidity around 70%.

NOTE

There should ABSOLUTELY NOT be any OZONEPRODUCING equip-

ment in the room, like operating electric motors or arc-welding, since ozone
destroys many rubber materials.

Do not store organic solvents or acids in the room.

Avoid heat and ultraviolet radiation.

If the equipment must be stored outdoor, the precautions mentioned above should
be taken as far as practical. The need for protection against the climate ect. is of
course even more important in this case.

1.1.0 Standstill
If the freshwater generator is out of operation for a period of 14 to 30 days.

• Close all valves in connection with the unit and it's pumps.

• Open drain valve on the freshwater generator.

• Open front cover and clean the unit inside with fresh water.

• Check that the anodes are functioning. If the anodes are not functioning or
worn out replace them.

Storage.fm 7
Pages 172
Storage/Long Term Standstill

• Let the unit dry out completely before closing and tighten the cover.

• Turn the pump/motor shafts once a week to avoid damaging the mechanical
shaft seal and motor bearings.

NOTE

To preserve the natural protection of the inside of the vessel DO NOT

scrape or scratch the inside surface.

1.1.1 Restart
Close drain valve on the freshwater generator and visually check outside for defects.

Before restart turn the pump/motor shaft by hand to check for any obstructions, after
starting the pump watch the operation of the pump and electric motor for approx. 10
minutes.

1.2.0 Long Term Standstill

1.2.1 Preservation Procedure for Freshwater Generator

If the freshwater generator is taken out of operation for a period longer than 30 days.

• Close all valves in connection with the unit and it's pumps.

• Open drain valve on the freshwater generator.

• Open front cover and clean the unit inside with fresh water.

1.2.3 Preservation Procedure for Pumps

• Drain the pump through the bottom drain.

• Flush the pump with hot fresh water (maximum 60 deg.C, 140 deg.F), flushing
can take place through the manometer connections.

• Let the pump dry out.

• Flush the pump with 'Mobil Arama 25' or similar quality.

• Mount drain plug and manometer connections.

• Turn the pump shaft once a week to avoid damaging the mechanical shaft seal.

1.2.4 Restarting of Pumps

• Fill the pump with hot fresh water through the manometer connections.

• Mount the manometer connections.

• Turn the pump shaft by hand to check for any obstructions.

• Open valves and check that the mechanical shaft seal is not leaking (if leaking
start the pump and let it run for 1 to 2 minutes, if still leaking the mechanical seal
must be replaced).

• Start the pump and watch the operation of the pump and electric motor for ap-
prox. 10 minutes.

1.2.5 Preservation Procedure for Electric Motors

Factory fitted bearings use a lithium based grease with a recommended shelf life of
two years. If stored for a longer period, grease may need to be replaced.

Shielded bearings have a storage life of five years and a further two years operational
life following the installation.

To avoid static indentation during long term standstill, the area should be vibration
free.

Where exposure to some vibration is unavoidable, the shaft should be looked. Roller
bearings may be fitted with a shaft locking device which should be kept in place dur-
ing long term standstill.

Shaft should be rotated by hand, one quarter of revolution weekly.

• Remove all surface dust and dirt.

• Test the stator insulation resistance between phases and also to earth.

If an insulation resistance lower than one megaohm at 20 deg.C (68 deg.F) is mea-
sured, the windings must be dried out until a minimum of one megaohm is obtained.

• Start the motor.

• Watch the operation of the electric motor for approx. 10 minutes.

1.2.7 Preservation Procedure for Electric Panel

The electric panel normally includes motor starters with thermal relays, transformer,
contactors and salinometer.

The panel have to be disconnected from the main supply and kept clean and dry dur-
ing the long term standstill period.

The panel is kept dry inside either by an anti-condensation heating element (25 W)
or by use of a desiccant.

WARNING

If anti-condensation heater is used, prominent warnings of live terminals in-

side the panel must be posted inside and outside the panel.

Inhwle00.fm 13
Pages 178
 System Description

1.0.0 Working Principle

Full Flow
The full flow of water is led to the heat exchanger. To achieve the required water
temperature, the flow is heated by steam to the set point.

The amount of steam is regulated by a steam valve, controlled by a thermostat or a

digital temperature regulator mounted after the mixing point. The hot water pump en-
sures a constant flow and makes recirculation possible during low engine load or
stop.

A blind connection at the inlet to the heat exchanger allows the module to be used
as a pre-heater. In this case, only the engine cooling water pump shall be running.
The hot water pump shall not be in operation. The outlet connection has to be
mounted by others after the Hot Water Loop.

Partial Flow
A partial stream of water is led to the heat exchanger. To achieve the required water
temperature, the partial stream is heated by steam to above the set point. As a re-
sult, the correct mixing temperature of the partial stream and the main stream is
achieved, i.e., equal to the set point.

1.1.0 Main Components

The Hot Water Loop consists of the following components:

1. Heat exchanger
The steam/water heat exchanger heats a partial stream of the jacket cooling
water by means of steam.

2. Steam valve & thermostat/PT100

Regulate the amount of steam after the outlet temperature (temperature after
the mixing point).

3. Hot water pump

Circulate the jacket cooling water and ensure a constant flow.

4. Water trap
Ensures that only condensate is led to the condensate tank/hot well.

5. Control panel
Motorstarter can either be built into the control panel of the freshwater gener-
ator or be in a separate panel which contains motorstarter for hot water pump,
running light, contact for remote alarm.

The HWLM 7-20 can also be delivered only with manual motorstarter.
