SAFETY AND PRECAUTIONS

Use EXTREME CAUTION when working in the vicinity of the dryer. Adhere to all warning labels on dryer.
Relieve pressure before servicing dryer or associated equipment.

Disconnect power before servicing dryer.

Always wear eye protection when in the vicinity of the dryer. Ear protection is recommended, especially if the dryer is
being operated without mufflers. Even when mufflers are used, a desiccant vessel blowing down to atmosphere will
raise particles, create more noise than during “normal” operation and may startle an individual not familiar with this
portion of the operation.

The dryer is uses heat to regenerate the desiccant. Any dryer surface may reach temperatures up to 350°F. Do not
touch hot surfaces. Partial insulation is provided to maximize dryer performance. The standard insulation does not
provide complete personnel protection or 100% thermal efficiency.

The emergency stop button will cut off 120V control voltage only. Supply voltage is not disconnected.

In the case of an overpressure situation there is a safety relief valve installed on each desiccant vessel designed to
protect the equipment. If the valves are pointed in a hazardous location to operators after dryer installation, they
should be piped to a safe location.

Dryers are designed for fail safe operation. In the event of a power failure, the inlet valves will fail in the open or last
position and the exhaust valves will fail closed. Compressed air will continue to flow through the dryer. When power
is restored, the cycle will continue on from where it left off at the time of the power loss.

Automatic or manual drain valves will eject water, oil, particulates, and air under partial pressure when operated.
Proper precautions must be taken.

Condensate drainage from compressed air systems may contain oil or other contaminants. Follow all applicable
regulations for safe handling and disposal.

Various component failures could cause large air loss and subsequent pressure drop. Preventative maintenance
should be performed to reduce this possibility. If this situation occurs, bypass the dryer immediately to restore
flow and pressure.

Oil in the desiccant bed combined with high regeneration temperature may create a potential for fire or
explosion. Proper cooling, pre-filtration, and condensate drainage must be maintained to reduce the possibility
of oil contamination.

Activated alumina dust is considered a nuisance dust. Proper precautions should be taken when handling desiccant.
For more information and for other types of desiccant, refer to the applicable Safety Data Sheet. For disposal of
used desiccant, refer to the local codes and regulations.

NOTE: desiccant contaminated with oil or other foreign substances may be covered under disposal regulations for
the contaminant.

Heated dryers are designed with a cooling cycle after heated regeneration to alleviate high temperatures from the
regenerated desiccant and vessel. It is normal for residual heat to remain in the regenerated vessel. Temperatures
of 200-350°F may be seen at switchover. The residual heat will dissipate quickly once the tower is online at full flow.
Downstream piping and components must be suitable for the elevated temperatures.

DOWNSTREAM AIR TEMPERATURE MAY EXCEED 200°F FOR A DURATION OF 15 MINUTES AFTER DRYING
VESSEL SWITCHOVER! TEMPERATURE CAN EXCEED 350°F AT LOWER FLOW!

INSTALLATION
Inspect the dryer upon receipt for any damage that may have occurred during shipment.

Each desiccant dryer is supplied with a User Manual, dryer general arrangement drawing, and ASME pressure
vessel U1A data reports (where applicable).

The initial charge of desiccant is included with the dryer. Ensure vessels are filled with desiccant prior to startup.
Models 2000 and larger include desiccant shipped separately in 25 lb bags to be installed by the user at the site.
Smaller dryers are shipped with desiccant installed.

Exhaust mufflers are supplied for each dryer. A quantity of two mufflers are shipped attached to the dryer, unin-
stalled, for models 200 and larger. Mufflers should not be installed until after startup to allow excess desiccant dust
to be cleared from the dryer and not prematurely clog the new mufflers.

The dewpoint sensor (optional) is shipped in a small container attached to the dryer. Take care not to misplace
before installing.

If placed in storage, place in a location protected from the environment. If stored outside, it is recommended that the
dryer be underneath a shelter and be shrink wrapped or crated to protect against rain. Desiccant dryers should not
be stored in a location exposed to freezing temperatures or direct sunlight. Dryers designed for outdoor use should
not be placed outside until ready for operation. All plugs and flange covers should remain in place until the dryer is
ready to be installed. Desiccant bags should remain in original closed packaging and be stored in a dry environment
until dryer is ready for operation. Dryers with desiccant installed should be stored in a dry environment.

The dryer should be moved using a pallet jack or fork truck. Desiccant dryers are tall and top heavy. Use caution
while moving the equipment to avoid tipping over. Many dryers have desiccant vessels equipped with lifting lugs.
DO NOT USE THE VESSEL LIFTING LUGS TO LIFT THE DRYER. They are only used to lift an empty vessel and are
not designed to hold the weight of the equipment.

Install in an area with an ambient temperature range of 40°F to 100°F. The area should be well lit and ventilated. It is
recommended to leave a minimum of four feet around all sides of the dryer for maintenance. Ensure that the dryer is
stable and properly secured on a vibration free floor before operation.

If installed outdoors, the desiccant dryer should be installed in an area protected from the effects of weather.
Locate under a roof if possible. Avoid direct sunlight so that the control display does not become damaged and can
be clearly read. If installed in an area with below freezing temperatures, proper heat trace and freeze protection must
be added to the equipment.

There are several connection points on the dryer. Make sure each connection is made prior to startup.

1. Air in connection – Will be marked on the dryer with a tag. Use piping suitable for the pressure and
  temperature class.

2. Air out connection – Will be marked on the dryer with a tag. Use piping suitable for the pressure and
  temperature class.

     3. Prefilter drain connection – Located near the prefilter and labeled. Drain discharge is under pressure
  equal to the system and must use piping suitable for the pressure and temperature class if piped to
  another location. A coalescer type prefilter must be installed before the desiccant dryer if not supplied
  with the dryer. It is critical to the performance of the dryer to protect the desiccant bed from oil bulk
  moisture contamination.

4. Dewpoint sensor (Power Lock options only) - Located near the prefilter and labeled. Drain discharge
  is under pressure equal to the system and must use piping suitable for the pressure and temperature
  class if piped to another location. A coalescer type prefilter must be installed before the desiccant dryer
  if not supplied with the dryer. It is critical to the performance of the dryer to protect the desiccant bed
  from oil bulk moisture contamination.

5. Power supply – Bring power to the high voltage panel. Verify voltage, phase, and frequency of power
supply matches dryer design by checking the serial label. Check that power supply is sufficient for amp
rating on serial label. Short circuit protection is the responsibility of the owner.

Mufflers are included with the dryer to reduce noise level only. They are not required for normal operation and
should not be installed for initial startup. The exhaust may be piped to another location to further reduce noise,

Each elbow installed in the exhaust piping is equivalent to 10 feet of pipe. If the exhaust piping is vertical, a drip line
must be installed to remove moisture. It is recommended to pipe the exhausts separately for ease of maintenance
and troubleshooting.

It is highly recommended to install bypass valves and piping around the dryer and filters to use during routine dryer
maintenance.

GENERAL OPERATION
The externally heated and blower purge desiccant dryers are designed to remove moisture in water vapor form, from
compressed air to yield dewpoints of -40°F or better. The twin tower design allows constant drying of compressed
air through one adsorption vessel while the other vessel desiccant bed regenerates by using heated dry purge air.

Compressed air is directed through the inlet valve and up through the drying desiccant vessel where moisture is
adsorbed by the desiccant. The low dewpoint dry air is then directed through the outlet check valve and down-
stream for use.

For externally heated dryers, regeneration of the saturated desiccant vessel bed is begun by blowing down the
saturated vessel bed. The quick change from line pressure to atmosphere causes moisture to detach itself from the
desiccant and be exhausted. The regeneration cycle is continued by directing 8% of the dry compressed air through
a purge valve and orifice. The purge air is expanded to atmosphere, passed across an electric resistance heater
where the air temperature is elevated to 400°F, then passed down through the saturated bed heating the desiccant.
Adsorbed moisture is released from the desiccant, and then exits the dryer through the exhaust valve and muffler.
Once heated regeneration is complete, the heater is powered off and cooling begins. Dry purge air continues to pass
through the regenerated bed, cooling it to reduce the air temperature spike downstream and allow the newly regen-
erated bed to readily adsorb moisture again after switchover.

For blower purge dryers, regeneration of the saturated desiccant vessel bed is begun by blowing down the sat-
urated vessel bed. The quick change from line pressure to atmosphere causes moisture to detach itself from the
desiccant and be exhausted. The regeneration cycle is continued by the blower pulling in ambient air and passing
this low pressure wet air across an electric resistance heater. The air temperature is elevated to 400°F, then passed
down through the saturated bed, heating the desiccant. Adsorbed moisture is released from the desiccant, and then
exits the dryer through the exhaust valve and muffler. Once heated regeneration is complete, the heater is powered
off and cooling begins. The blower continues to pass air through the regenerated bed, cooling it to reduce the air
temperature spike downstream and allow the newly regenerated bed to readily adsorb moisture again after switcho-
ver. A stream of dry purge air in the amount of 2% may also be used after blower cooling to reduce the dewpoint
spike at switchover caused by using wet ambient air with the blower.

Once regeneration is completed, the offline desiccant vessel is slowly pressurized to system pressure. The dryer is
ready for switchover, at which point compressed air will be directed though the newly regenerated desiccant bed for
drying and the opposite desiccant vessel begins regeneration. This cycle continues automatically.

The dryer inlet, exhaust, and repressurization valves are controlled by solenoid actuated control valves, which are
controlled by the dryer PLC. The PLC operates opens and closes the valves using a programmed timing sequence.
The PLC is equipped with various timing cycles to maximize the dryer efficiency. It is also possible to extend the
drying cycle time using the dewpoint demand function.

START UP

Verify all piping and electrical connections are secure. Do not power the dryer at this time.

Start the compressor and pressurize the air system, bypassing the dryer.

Slowly pressurize the dryer by opening the inlet isolation valve. It is important to allow the dryer to slowly
pressurize to prevent fluidization of the desiccant bed. Rapid pressurization can also cause damage to the
vessel internal screens and filter elements.

The dryer must be started without the mufflers installed. This will expedite removal of excess desiccant dust and
prevent premature clogging of the mufflers.

CAUTION: USE EAR AND EYE PROTECTION WHEN OPERATING THE DRYER WITHOUT MUFFLERS. EXCESSIVE
NOISE WILL BE CREATED. DUST AND PARTICLES FROM THE SURROUNDING AREA MAY BECOME AIRBORNE.
OPERATION WITHOUT MUFFLERS EXCEEDS OSHA LIMITS.

Open the control air ball valve.

Push in the emergency stop button.

Power up the dryer. Check rotation of blower by pushing in contactor manually. If opposite of the flow direction
arrow, switch the two leads.

Pull the emergency button out.

Start in Heatless - Touch the START IN HEATLESS OPERATION button from the controller’s SERVICE screen to
start the dryer. The dryer will initially ensure that vessels are pressurized, then will begin by blowing down one
of the vessels while placing the opposite ‘drying’ vessel online. If you do not want the dryer to begin cycling
automatically, close the control air ball valve. This will prevent the inlet and exhaust valves from switching. In this
situation, a bad blowdown alarm will occur which must be reset from the control panel after re-opening the control
air ball valve.

The dryer can be run in the heatless mode for two or three cycles to quickly remove desiccant dust caused by
shipping or filling the unit. This also serves to verify that the vessels are switching normally, and to allow resolving
any issues with system pressure before applying heat the regeneration process.

Switch to Heated - When you are ready to switch the dryer to HEATED regeneration operation, simply touch the
START IN HEATED OPERATION button from the controller’s Service screen. The dryer will immediately repressurize,
then switch towers and start HEATED regeneration on the opposite vessel.

Install the exhaust mufflers on the dryer.

Check Purge Pressure - For TWP dryers, verify the purge pressure setting is correct for the operating conditions.
The purge pressure setting must be set to the factory advised setting while using the dewpoint demand feature.
The purge pressure must be set while in the Heated Regeneration State. Do not adjust the purge pressure when
operating in the heatless backup timing configuration.

Heating - Verify that the heater contactor(s) pull in and the purge air temperature value on the controller screen
begins to rise. If the dryer is blower type, then the blower will also be running at this time.

Over-Temp - There is a redundant over-temperature module inside the control cabinet that is preset at the factory to
650°F. This module monitors a thermocouple for purposes of independently sensing an over-temperature condition.
In addition, there is an over-temp setting, also preset the factory to 650°F, accessed from the ADVANCED SETTINGS
screen on the controller. This setting is associated with the purge temperature sensor.

22
TWP/TWB200 – TWP/TWB9000

It is not uncommon for the heater to shut down due to an over-temperature condition during initial startup of the
dryer. If this should happen, verify that the purge pressure setting agrees with the suggested setting and that there
is no backpressure in the regenerating tower (as would occur if a muffler was clogged or a check valve was not
functioning properly). If there is no sign of back pressure, then increase the overtemp adjustment on the over-temp
module, and the over-temp setting in the Advanced Setting screen by 50°F increments and reset the alarm. Repeat
until optimal overtemp settings are achieved. Consult factory if the dryer continues to shut down on over-temp at a
setting of 750°F or above.

Slowly open the dryer outlet isolation valve. Close the bypass valve. If applicable, tighten manway cover bolts. It is
common for the manway gasket to undergo additional compression on startup.

TIMING CONFIGURATION
The controller is designed for externally heated, blower purge and heatless backup cycle operation. The timing
configuration is pre-set at the factory for the specific dryer model. The default timing settings for each configuration
are listed below.
Heatless Backup Cycle: 14 min
Externally Heated Cycle: 8 hours Blower Purge Cycle: 8 hours
Drying: 7 min per tower.
Drying: 4 hours per tower. Drying: 4 hours per tower.
Purging: 6 min per tower.
Heating: 2 hours 30 min per tower. Heating: 2 hours 30 min per tower.
Repressurization: 1 min per.
Cooling/Purging: 1 hour 27 min per Cooling: 2 min per tower.
tower.
Purging: 85 min per tower.
Repressurization: 3 min per tower.
Repressurization: 3 min per tower.

The heating time is the maximum per tower per cycle. To save energy, the system is designed to end the heating
cycle and advance to cooling once the offline tower is fully regenerated. For blower purge models, the user may
disable the 2% cooling feature in order to prevent using dry purge air during regeneration. The cooling time will then
default to 25 min per tower per cycle.

Externally heated and blower purge dryers are both equipped with a heatless backup cycle as a standard feature.
This configuration may be selected by the user to use dry purge air for regeneration in place of heated air.
This operating cycle consumes 15-18% dry purge air and has a much shorter cycle time than the heated cycle.

Heatless backup can be used when there is an issue with the heated regeneration function of the dryer, but dry air is
still needed. The heatless backup cycle will allow the dryer to continue to produce dry air until a time when the dryer
can be shut down for service and maintenance. Heatless backup can also be used to more quickly purge a new
or oversaturated dryer. Once the dryer begins to achieve consistent dewpoint, the dryer can be switched back to
HEATED REGENERATION.

The dewpoint demand function is an energy savings feature that extends the drying cycle as long as the user
defined dewpoint requirements are met. The offline desiccant vessel completes its regeneration process as normal
and then waits in an idle state until the dewpoint degrade to the setpoint before switching over. By extending the
drying cycle, less purge air is consumed over a period of time. The Dewpoint Demand feature must be set to
ENABLED and the dewpoint sensor must be installed in the DEWPOINT SETTINGS screen.

23
TWP/TWB200 – TWP/TWB9000

MANUAL STEPPING

This feature is used to assist in maintenance and troubleshooting of the dryer. Touching the STEP button at the
main screen will advance thru the regeneration states. This allows the user to skip ahead to desired stages of the
regeneration process more quickly. Using this feature may yield worse than desired dewpoints until the dryer is
allowed to cycle uninterrupted. For safety, when attempting to switch out of repressurization or blowdown, the dryer
will wait until the pressures in the tanks are at a safe level before proceeding to the next state.

CAUTION: Never step through the cooling state. Doing so may result in extreme temperatures being released
downstream. Only switch out of cooling if you are certain there is no possibility of releasing dangerous heat
downstream.

CONTROLLER DISPLAY & OPERATION

The dryer’s controller is an Allen-Bradley® PLC coupled with a proprietary color, touch panel HMI. The controller
is factory programmed with the proper timing configurations for the dryer model. The controller features user
configurable drain settings, timing configuration, dewpoint demand cycles, system pressure and temperature
monitoring, system alarms with user configurable settings and alarm log, and a manual stepping feature for
maintenance. Additionally, there is reference information for troubleshooting dryer operation and alarms.

The standard controller display is accessible at the front of the dryer without opening the enclosure. If the enclosure
must be opened, always remember to close and secure the enclosure door when not using!

WARNING! - DO NOT ATTEMPT TO CHANGE SETTINGS OR OTHERWISE OPERATE THE DRYER REMOTELY
WITHOUT A FIRM UNDERSTANDING OF DRYER OPERATION. IMPROPER SETTINGS OR CONTROL MAY
RESULT IN DAMAGE TO DRYER COMPONENTS OR PHYSICAL INJURY.

The user’s panel includes an Ethernet and a Serial port which can be used for Modbus communications. The Ether-
net port can be used to access Modbus/TCP registers, as well as, the internal VNC servers across multiple dryers.
The Serial port can access Modbus RTU registers on a single dryer using either RS232 or RS422/485
hardware protocol.

VNC Server

The internal VNC server runs in the back ground by default. Any VNC Client may be used to access the dryer’s VNC
server via port 5900.

Excessive network traffic or network interference may cause the VNC server to intermittently shut down. Rebooting
the HMI via the Service menu or via Modbus register 40101 will restore the VNC Server after reboot.

Ethernet

The Ethernet port is pre-configured to acquire its network IP address and configuration from the network’s DHCP
server. Proper cabling and isolation techniques are required to prevent electrical noise from entering the system
through this port. Contact your local electrical parts distributer for assistance.

Serial Modbus Port

The serial port is located along the bottom edge of the HMI. This port supports full RS232, RS422, and RS485 hard-
ware protocols. This port is NOT isolated. Proper cabling and isolation techniques are required to prevent electrical
noise from entering the system through this port. Contact your local electrical parts distributer for assistance.

SHUT DOWN
The dryer should be sufficiently cooled down and allowed to repressurize before shutting down. Allow dryer to run
normally or use the manual stepping feature to proceed to the cooling stage and wait for cooling to end. After the
regenerating tower has sufficiently cooled down, place the dryer into STANDBY.

If the dryer is operating in the heatless backup mode of operation, place the dryer immediately into stand by.
Wait for the dryer to repressurize, then push the emergency stop button and open the main electrical disconnect.

Once the dryer is in STANDBY, the EMERGENCY STOP button can then be used to remove power from the valves,
the heater, and the blower. Open the main electrical disconnect to completely remove power from the dryer.

To put dryer into STANDBY, press the SWITCH TO STANDBY button on the display. The GOING TO STANDBY
message will appear on the screen. If pressed during the heating cycle, the dryer will proceed to cooling for two
minutes. Once the dryer repressurizes, the status message will change to read DRYER IN STANDBY. Both tanks
will be pressurized and the heater will remain off. To restart, press the DRYER IN STANDBY button on the display.
The regeneration cycle will immediately resume at the point in the regenerating process where the stand by button
was first pressed.

To depressurize the dryer, first follow the appropriate shutdown procedure. Open the dryer bypass valve.
Close the outlet isolation valve, and then the inlet isolation valve.

Open the manual drain valve on the afterfilter or control air filter to allow full depressurization of the dryer.
Verify all pressure is removed from equipment and power is disconnected before servicing.

If a dewpoint sensor is installed and the dryer will be out of service for an extended period of time, remove the
sensor and place in a safe, dry location. The sensor will be damaged if exposed to prolonged periods of saturated
conditions.

The dryer should be immediately bypassed to prevent loading the desiccant beds while the dryer is out of service.

MAINTENANCE
Use caution when near the dryer and wear eye protection. Hearing protection is recommended. Dryer maintenance
should only be performed by trained personnel. Always shutdown the dryer, relieve all pressure, and disconnect
power before servicing.

Consult service manual for additional information on part replacement.

Daily

Check the dewpoint of the compressed air system to ensure it is in good operating condition.

Check drain for proper function. Ensure drain is not clogged.

Check purge pressure setting (TWP only), proper prefilter drain operation, and verify no back pressure on regenerat-
ing vessel to avoid more serious operating issues.

Check for proper heater and desiccant bed temperatures.

Check controller for any active alarms.

52
TWP/TWB200 – TWP/TWB9000

Weekly
Check air flow rate, air inlet pressure and temperature are within design specifications of dryer.

Check blower and blower inlet filter. (Blower purge models only).

Semi-annual
Check the condition of the prefilter and afterfilter elements. Verify the differential pressure across the filters.
Replace as needed.

Check desiccant quality. Desiccant from a freshly regenerated bed should be white, dry to the touch and of consis-
tent size and shape. Continuous adsorption and desorption causes the performance level of desiccant to decline
over time. Oil and contaminants causes reduction in the adsorption ability of the desiccant. It is recommended to
replace the desiccant every 3-5 years.

Check exhaust mufflers and verify there is no back pressure in regenerating vessel. If the muffler is clogged, it must
be cleaned or replaced.

Tighten wire connections to heater. Stud terminals should be tightened to a maximum torque of 20 in-lbs while the
bottom nut is supported. Stud terminals that do not have a bussbar or factory installed ring connector should only
be tightened to 9 in-lbs.

Check condition of blower inlet filter element and replace as needed. (Blower purge models only).

Inspect blower drive belt and idler pulley. Replace if needed. (Blower purge models 4000-9000 only).

Annual
Check condition of control air filter element. Replace as needed.

Check condition of all inlet and exhaust switching valves. It is recommended to clean and rebuild the valves to
maintain proper working condition.

Check dewpoint sensor and recalibrate as needed.

Check contactors and starters. Replace as needed.

Inspect blower head, tensioner, and pulleys for correct operation. (Blower purge models 4000-6000 only.)
