4. Technical functions
Air-air heat exchangers are intended as complementary accessories to large industrial equipment which include
a motor-operated fan or blower together with a heat exchanger module. These may also include an electric
heater. The fan or blower is intended to recirculate air and allow heat exchange. The heat exchanger is
designed for air heat transfer only.
Cooling function may be controlled by an on-board or remote controller or thermostat. Heating function, when
installed is provided by an electrical heating element. The unit seals the cabinet which ensures that the clean air
inside does not come into contact with the ambient air which may well be dirty or polluted. The unit is fit for
purpose within the rated/declared ambient conditions (e.g. dusty and oily air or high air temperatures between
-5°C and 55°C), also indicating the rated allowable ingress and environment.
Heat exchangers are used where the heat generated by energy losses in control cabinets must be conducted
away to protect temperature-sensitive components. The characteristic graph shown in the section “Performance
graph” applies to external (ambient) air as the coolant.
In air-to-air heat exchangers, the internal temperature of the control cabinet cannot be cooler than the ambient
temperature. There are natural limits to the cooling performance, dependent on the air supply temperature and
the requirement for a temperature difference of at least 5K. Unlike systems in which the heat generated is
allowed to escape by air convection through ventilation slots, with the heat exchanger, the clean air inside the
control cabinet is prevented from mixing with the air outside, which may well be unclean.
5. Functional principle
Functional principle
The heat exchanger is a cooling device that creates a heat-transfer through a large area of thin aluminium sheet
metal folded up in the heat exchanger core by means of forced convection. Used within an enclosure, it uses the
ambient air as cooling medium, thus avoiding the utilisation of refrigerant.
The cooling performance of the heat exchanger is dependant on the ambient (external) air temperature. The
internal fan is set to be always on. The external fan is controlled via a thermostat. When the cabinet
temperature increases beyond the pre-set thermostat temperature, the external fan is switched on and the heat
exchanger starts cooling. Cooling stops when the cabinet temperature cools below the pre-set temperature.
Switching difference is of 7K (+/-4K).

7. Mounting
Danger from electrical voltage
The unit must be mounted by specialist personnel (qualified electricians). The personnel must ensure that the
cabinet is disconnected from the electrical supply for the duration of the mounting operation. Therefore take the
cabinet out of operation, following the relevant instructions before mounting work commences.
Danger through incorrect work on the unit. Only specialists are allowed to put the unit into operation.
Mounting preparations
Several points must be checked before the unit can be mounted. These checks must be made to ensure safety
and the trouble-free operation of the unit. These checks must be carried out with absolute thoroughness to
ensure that the unit works perfectly.
Transport damage check
On delivery the carton containing the unit must be examined for signs of transport damage. Any transport
damage to the carton could indicate that the unit itself has been damaged in transit which in the worst case
could mean that the unit will not function.
Location and space requirements
The location of the cabinet must allow for sufficient air circulation to and from the unit. The unit should be
mounted roughly horizontally. It is therefore advisable to check that the cabinet is in a horizontal position. The
max. deviation from the vertical or horizontal should not excess 20 degrees.
Sealing
To guarantee that the unit works perfectly ensure that, the control cabinet is completely sealed (to min. IP54 to
EN 60529) and a good seal exists between the control cabinet and the unit. If necessary the cabinet mounting
surface should be reinforced.

8. 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.
Connection to the main electrical supply
To connect the unit to the mains proceed as follows:
Take the control cabinet out of operation in the prescribed manner.
See the connection details on the circuit diagram.
Note the connections on the connector / terminal block from the following table
Terminal 48V DC
+ 1 Positive
- 2 Negative
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.

10. Taking into operation
As described before the unit is controlled in relation to the cabinet internal temperature. The required cabinet
temperature can be set on the potentiometer on the controller.The temperature adjustment range is between
0°C (left-hand stop) and 60°C (right-hand stop). The thermostat is pre-set at 35°C.
To adjust the cabinet internal temperature proceed as follows:
Remove the MCB access plate on the front of the unit.
Using a screw driver turn the adjustment wheel on the potentiometer “TEMP” slightly to the right (higher)
or to the left (lower).
Please note that the setting for the alarm signal should be at least 5 - 10°C higher than the setting for the
cabinet internal temperature.
Check that the new adjustment meets the necessary requirements. If necessary, repeat the procedure. Inspect
and if necessary replace the MCB access plate sealing tape.
11. Trouble shooting
In case of a fault logon to our website www.seifertsystems.com to locate your nearest servicing office or find
your nearest contact in the chapter “contacts” in this manual.
12. Maintenance & Cleaning
Danger from electrical voltage
Maintenance and cleaning must be carried out by specialists
(electricians). 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 reactivation.
Danger through incorrect work on the unit.
The instructions in the cabinet manufacturer’s manual must be
adhered to!
Damage to the unit through incorrect maintenance and
repair! Maintenance and repair must be carried out by the
manufacturer or another specialist.
Fan replacement
The rated life expectancy of the fan is L10 =30,000 hours under normal operating conditions.
To replace the internal or external fan, please proceed as following:
Remove the internal access panel by unscrewing the 10 fixing screws.
Disconnect the blower cables from the connectors.
Unscrew the four screws fixing the blower bracket to the cabinet.
Unscrew the fan from the bracket.
Re-assembly with the new blower is in reverse order.
Make sure that the blower cable length is the same as the one of the removed fan to ensure that the cable does
not come in contact with the blower while in operation. Make sure that the correct polarity is maintained. (Refer
to circuit diagram). Inspect and if necessary replace the internal access panel sealing tape.
In addition the unit should have regular functional tests (approx. every 2,000 hours depending on the grade of
ambient pollution).

13. Transport & Storage
Malfunction due to transport damage
On delivery the carton containing the unit must be examined for signs
of transport damage. Any transport damage to the carton could
indicate that the unit itself has been damaged in transit which in the
worst case could mean that the unit will not function.
Storage conditions
The unit can only be stored in locations which meet the following conditions:
Temperature range: - 40°C to + 70°C
Relative humidity (at 25°C): max. 95%
Returning the unit
Damage to the unit through incorrect transport.
To avoid transport damage the unit should be returned in the original
packing or in a packing case and must be strapped to a pallet!
If the unit cannot be returned in the original packing please ensure that:
A space of at least 30 mm. must be maintained at all points between the unit and the external packing.
The unit must be firmly fixed in the packing.
The unit must be protected sufficiently by shock absorbing padding (hard foam corner pieces, strips or
cardboard corner pieces).
