Settings
Peltier cooling units are intended to be used as a complementary accessory to
larger industrial equipment. They are 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 an
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 that are dusty and oily and where
temperatures may vary from -20°C to +65°C. For the cooling capacities and
environmental ratings please refer to the type plate data.
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.

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 the cabinet and the cooling unit must be <0.1Ω.
Condensate management
Depending on the mounting situation the condensation management may need to be considered and possibly adjusted.
Mounting Principle
In order to maintain the TYPE 4 rating, the tightening torque for this unit should be 4.5 Nm and needs to follow the below sequence.

Electrical Connection
High electric voltage present. Installation, maintenance, cleaning, and any
other work must be carried out by quality 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
unauthorized/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 main 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 24 V DC
1 | Ambient Fan + |
---|---|
2 | Ambient Fan – |
3 | Internal Fan + |
4 | Internal Fan – |
5 | Thermoelectric Elements + |
6 | Thermoelectric Elements – |
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.

The internal fan must operate continuously. Ambient fan and thermoelectric elements must be controlled simultaneously by a thermostat (or similar temperature controller).
Taking into Operation
The power supply rating on the rating plate must comply with the mains supply
Always disconnect the power supply before opening the unit.
Heat load to be dissipated from the enclosure should not exceed the specific
cooling output of the unit at any condition.
When 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 100 – 230 V supply have already a controller integrated.
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
Maintenance & Cleaning
Always switch off power supply before starting any work on the unit. Only qualified personnel 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 dirty proceed as follows:
- 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 follows:
- 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 the cooling unit and used parts with due regard for the environment
and in accordance
with environmental laws and regulations.
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 follows:
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.
Transport & Storage
During transport and storage, the cooling unit must be kept in the position marked on the box and at a temperature between -40˚C and 70˚C and relative humidity of max. 95% (at 25°C). In case of damaged packaging after transport or in-house handling, we recommend controlling the unit for any internal damages.
