4. Technical information
Peltier cooling units are intended to be used as a complementary accessory to larger industrial
equipment. Theyare used where heat needs to be dissipated from electrical control cabinets or similar
enclosures in order to protect heat sensitive components.
Peltier cooling units can dissipate heat from sealed enclosures such as control cabinets. At the same
time they can reduce the cabinet internal temperature to below the ambient air temperature. They are
available in powder-coated sheet steel or stainless steel housings. Peltier units have additional heating
function by changing the supply polarity of the thermoelectric elements. This is possible by using a
combination of thermostats or having a specific polarity controller.
Peltier air conditioners are resistant to extreme ambient conditions and can operate effectively even in
environments which are dusty and oily and where temperatures may vary from -20°C to +65°C. For
the cooling capacities and evironmental ratings please refer to the type plate data.
5. Functional principle
The thermoelectric elements create a temperature difference between the internal and ambient heat
sinks, making internal air cooler while dissipating heat into the external environment. Fans help the
transfer of convective heat from the heat sinks, which are optimized for maximum flow. Peltier units be
mounted in any position because these units don’t have a compressor and no moving
parts. Depending on the mounting situation the condensation management may need to be
considered and possibly adjusted.

8. Mounting
Always switch off power supply before starting any work on the unit.
Installation
Ensure that flows of air leaving and entering the cooling unit, internal and external, are not obstructed.
Before drilling the enclosure, ensure the fixing elements and couplings will not interfere with the
equipment inside the enclosure itself. When all mounting preparations are complete the actual
mounting operation can commence. Only use the enclosed material to mount the unit on the cabinet.
Proceed as follows to mount the unit on the cabinet:
• Set the unit up on the cabinet.
• Ensure that the electrical connection is above the internal fan.
• Unit without duct: screw the M6 locknuts & washers into the M6 set screws in the unit.
• Unit with duct: screw the M6 screws & washers into the M6 threaded rivets in the unit.
The resistance of the earth connection between cabinet and cooling unit must be <0.1Ω.

11. Electrical connection
High electric voltage present. Installation, maintenance, cleaning and
any other work must be carried out by qualified personnel only. The
personnel must ensure that for the duration of this work the unit and
the cabinet are disconnected from the electrical supply and protected
against unauthorised/accidental reconnection.
Instruction: Check that the available voltage, frequency and fuse rating are the same as those stated
on the unit data label.
Connection to the main electricity supply
The mains connection is made via a cable. To connect the unit to the mains supply proceed as follows:
Disconnect the control cabinet from the mains.
●
󰾬See the connection details on the circuit diagram.
●
Note the connections on the four pole terminal block from the following table.
●
Terminal 12 V DC
1 Ambient Fan +
2 Ambient Fan -
3 Internal Fan +
Ensure that the correct polarity is maintained. The fans should have
clockwise rotation.
Connect the unit to the mains.
●
Take the control cabinet back into operation in the prescribed manner.
●
Power consumption and start-up current are stated on the data label and under technical data.

13. Taking into operation
The power supply rating on the rating plate must comply with mains
supply
Always disconnect the power supply before opening the unit.
Heat load to be dissipated from enclosure should not exceed specific cooling output of the unit at any
condition. While selecting a cooling unit always cater for a safety margin of at least 15% extra cooling
output.
The Peltier - elements should be controlled by a suitable thermostat. Models TG 6XXX with 230 V
supply have already a controller integrated
14. Trouble shooting
In case of a fault please contact your nearest servicing office. A list of service partners can be found on
our website www.seifertsystems.com
15. Maintenance & Cleaning
Always switch off power supply before starting any work on the
unit. Only qualified personal may conduct any maintenance work on the
cooling unit.
All Peltier units are virtually maintenance-free and no filters which need to be cleaned or replaced.
Check the ambient heat sinks from time to time. In case they are durty proceed as following:
Disconnect the enclosure from the mains.
●
Clean the heat sink profile as required by blowing it out with compressed air.
●
In cases of extreme pollution wet cleaning is required.
●
The unit must be removed from the control cabinet for wet cleaning
Should a wet cleaning be necessary proceed as following:
Disconnect the whole plant from the mains.
●
Remove the unit from the cabinet.
●
Ensure that the seals are not damaged.
●
Wash the heat sink with an environmentally safe cleaning fluid.
●
Danger to the environment through unauthorized disposal.
Disposal
Dispose of cooling unit and used parts with due regard for the environment and in accordance
with environmental laws and regulations.

Version Nr. 1-1 - 11.11.2017 Doc. Nr. 993030305 12 / 12
16. Maintenance
Note: Only use original replacement parts when repairing the unit. This ensures that the unit functions
perfectly and remains safe.
Fan replacement: The average working life of the fan is ca. 40,000 hours under normal conditions.
Should a fan replacement be necessary proceed as following:
Disconnect the unit from the mains.
●
Remove the unit cover.
●
Remove the screws from the relevant fan.
●
Mount a new fan.
●
Damage to the unit through incorrect work.
Make sure that the cabinet fan or the ambient fan are not misplaced in the unit
as they are different. Ensure that the correct polarity is maintained. The fans must
rotate clockwise!
Replace the 4 fan fixing screws.
●
Close the unit and take it back into operation.
●
17. Transport & Storage
During transport and storage the cooling unit must be kept in the position marked on the box and at a
