1 Safety information

1.1 General safety notes

A through flow cooler serves for due cooling of heat transfer liquids which are tempered by means of
a bath thermostat and transferred by pumping. This leads to hazards through high temperatures, fire,
and the general hazards through the use of electrical energy.
The user is largely protected through the application of the appropriate standard specifications.
Additional hazards may arise from the type of material being thermostated, e.g. when going above or
below certain temperature levels or through breaking of the container and reaction with the heat
transfer liquid.
It is not possible to cover all possibilities; they remain largely within the responsibility and the
judgement of the user.


The equipment must only be used as intended and as described in these Operating
Instructions. This includes operation by suitably instructed qualified personnel.

The units are not designed for use under medical conditions according to DIN EN 60601-1 or
IEC 601-1!

1.2 Other safety notes

 Connect the equipment only to an earthed supply socket.
 Use suitable hoses.
 Protect tubing with hose clips against slipping off. Prevent kinking of tubing!
 Check tubing from time to time for possible material fatigue!
 Heat transfer tubing and other hot parts must not come into contact with the supply cable!!
 During operation of the through flow cooler, hot tempering liquid may penetrate through the hose in
case of hose rupture, thus constituting a danger to persons and material goods.
 Depending on the heat transfer liquid used and the method of operation it is possible for irritating
vapours to be produced. Ensure appropriate ventilation!
 When changing the heat transfer liquid from water to liquids for temperatures above 100 °C
carefully remove all traces of water, also from tubing and from the external circuit, otherwise 
danger of burns through delayed boiling!
 Always pull out the mains plug before cleaning, maintenance or moving the through-flow cooler!
 Repairs must only be carried out by properly qualified personnel!

4 General construction and technical description

These operating instructions apply to four through-flow coolers of various cooling capacities.

Common feature of all four units are the air-cooled, fully hermetically sealed and thus maintenance-
free refrigeration units, the heat carrier circuit in stainless steel and the possibility of electrical
connection to LAUDA thermostats.

The refrigeration unit consists essentially of a hermetically sealed compressor. Heat of condensation
and motor heat are dissipated through a fan-cooled finned tube condenser. The fresh air is drawn in at
the front of the unit; the heated is discharged to the back and to the side. In order to ensure problem-
free air circulation the ventilation openings must not be obstructed.

The compressors have an over-temperature cut-out which acts on the compressor temperature and
current consumption of compressor. Furthermore the cooling system is protected by an overpressure
cut-out against excessive pressure.

The built-in refrigeration unit continuously cools down a heat exchanger (evaporator) insulated with
polyurethane foam. The connections of the heat exchanger are mounted at the back and are provided
with tube fittings M16 x 1 to connect olives with a diameter of 13 mm / 11 mm or metal hoses. The
pump of the connected thermostat pumps the heat transfer liquid through the heat exchanger of the
through-flow cooler. The through-flow cooler continuously cools down and the thermostat maintains
the required temperature by means of controlled counter-heating.

The through flow cooler DLK 45 equipped with LAUDA heating thermostats of the Ecoline E 3XX
series and older thermostats with incorporated P electronics allow a method of operation
corresponding to the proportional cooling. The cooler DLK 45 LiBus with LAUDA heating thermostats
with LiBus (at present Proline) also allows a method of operation which is equivalent to the
proportional cooling.

The cooling capacities indicated in the technical data sheet are gross values. To get the true effective
cooling capacities in case of operation, the heat emission of the pump as well as the insulation losses
have to be taken into consideration and deducted. This is decisive for the lowest temperature which
can be reached if a thermostat is connected. The indicated operating temperature range refers to the
combination with a small or medium-sized bath/circulation thermostat.
(i. e. DLK 10 – E 103; DLK 25 – P 8 C; DLK 45 – PVL 24.)

5 Unpacking and setting up

Never put the device into operation if you have discovered any transport damage.
The unit may NEVER be overturned nor put upside down!

5.1 Unpacking
Carefully packing should prevent transport damage. If, however, the units should arrive damaged, the
carrier or the post office has to be informed so that it can be inspected.

5.2 Setting up

 
air outlet
air inlet

The condenser of the refrigeration unit is air-cooled. Fresh air is drawn in at the front of the unit and
blown out at the back. Thus, the unit must be set up so that the free air flow is not obstructed.
Recommended distance: 50 centimetre at least.
It is particularly important that the air drawn in is not excessively warm. The unit must not be placed near
a radiator or any other source of heat.

Higher ambient temperatures result in a reduced performance. When the compressor is overloaded
because of high refrigerant pressure or high ambient temperature, the power supply is automatically
interrupted via a temperature switch. The compressor switches on automatically as soon as it has
cooled down.

Through flow coolers

6 Connection of external systems

A through-flow cooler can be only connected to thermostats which are equipped with a circulating
pump and connectors for the connection of external circulating systems. For connection the use of
insulated tubing with a maximum possible inside diameter is recommended.
To guarantee good circulation of the pump the tubing should not be too long. If possible, place the
through-flow cooler directly near the thermostat, especially when operating with the DLK 45 and the
DLK 45 LiBus with proportional cooling.

Secure tubing with clips to prevent its slipping off or use stainless steel metal hoses with screwed
connections!

6.1 Thermostats without external systems

Thermostat DLK

The figure shows the easiest possibility of connection. The connectors of the circulating pump are
connected to the fittings of the through-flow cooler.

 Pay attention to the through-flow direction! If the connections are interchanged, the
cooling capacity will be reduced as an air cushion may develop in the plate-heat
exchanger.

8 Starting up
 Always connect the unit to a grounded socket only. Check details on the type label against the
supply voltage.


Note for electric installation on site:

Single-phase devices:

Single-phase devices must be protected with a 16 ampere circuit breaker fitted during
installation.

Exception: Devices with 13 ampere UK plugs.

 Secure hoses against slippage with the aid of hose clips.
 When the DLK is connected to a thermostat, switch the thermostat on. The DLK control unit must
be activated in the thermostat in any case if it’s an Ecoline E 3XX, Proline or P control unit
thermostat.
 Switch on the mains switch (green) on the DLK.
 If the DLK 25 or the DLK 45 has to be controlled by a thermostat, the cooling switch (yellow) must
be switched to the AUTO position. ( Chapter 7.2, 7.3 and 7.4)
The through-flow cooler automatically starts running together with the thermostat. The yellow

signal lamp indicates that the refrigeration unit is switched on. The DLK is protected against
freezing because there is no through-flow when pump is not running.

 For manual operation, position the cooling switch (yellow) on . The AUTO function is then
neutralized. ( Chapter 7.1)

NOTE:
Switching on: First switch on thermostat, then switch on through-flow cooler by
means of the mains switch (green signal lamp lights up).

Switching off: First switch off through-flow cooler, then thermostat.

Never allow the through-flow cooler to run without liquid as in this case the
remaining liquid in the exchanger will excessively be cooled down to lowest
temperature. It will freeze resulting in damaging the exchanger.

9 Maintenance
Before repair or cleaning is done, pull out the mains plug!
Repair at the control panel and the lower part of the unit should only be executed by a qualified
electrician.

The refrigeration unit operates largely without maintenance. If the units operate under dusty
conditions we recommend that the refrigerator condenser is cleaned quite often. This is done best
with compressed air or nitrogen that is blown into the ventilation openings for a few minutes. If
necessary unscrew the front ventilation grill.

The refrigeration circuit of the DLK 10 is charged with R-134a, the refrigeration circuit of DLK 25,
DLK 45 and DLK 45 LiBus is filled with R-404A.
Repair and disposal must be executed by a qualified refrigeration engineer.

9.1 Cleaning
Clean the units with a cloth, wetted with water and some drops of tensids (washing-up liquid). No
water must enter the control panel.

The user is responsible for any necessary decontamination if dangerous materials have been spilled
on or inside the unit. This applies in particular if the unit is removed for a different use, for repair,
storage etc.

The method of cleaning or decontamination is determined by the expertise of the user himself. If the
user has any doubts on whether this may damage the unit he can contact the manufacturer.
