The cooling unit is used where heat needs to be dissipated from electrical control cabinets or similar enclosures in order to
protect heat sensitive components. The unit has two completely separate air circuits which ensure that the clean cabinet
air does not come into contact with the ambient air which may well be dirty or polluted. Control cabinet air conditioners can
dissipate large quantities of heat from sealed enclosures, such as control cabinets, into the ambient air and at the same time
reduce the cabinet internal temperature to below that of the ambient air.
The control cabinet air conditioner can function without problems in extreme ambient conditions (e.g. dusty and oily air)
with a standard operating temperature ranging between -4°F and 131°F. The stated cooling capacities are according to DIN
3168.
Door Switch
The unit can be switched on and off via a door contact switch. When delivered the door contact terminals are bridged on the
female connector. To connect the door contact switch remove the bridge and connect door contact switch. The contact must
be closed when the cabinet door is closed.
The cooling unit is intended to be used as a complementary accessory to larger industrial
equipment. The unit is used where heat needs to be dissipated from electrical control
cabinets or similar enclosures in order to protect heat sensitive components. It is not
intended for household use. The unit has two completely separate air circuits which
ensure that the clean cabinet air does not come into contact with the ambient air which
may well be dirty or polluted. Enclosure cooling units can dissipate large quantities of
heat from sealed enclosures such as electrical enclosures into the ambient air and at
the same time reduce the cabinet internal temperature to below that of the ambient air.
The unit can function without problems in extreme ambient conditions (e.g. dusty
and oily air) with a standard operating temperature ranging between +10°C and
+55°C. Units can be ordered with an additional electrical cabinet heater. For the
cooling capacities and environmental ratings please refer to the type plate data.

The display shows the temperature in the range of -50°C to +150°C (-58°F to +302°F). The
temperature is displayed with resolution of tenths between -19.9°C and +99.9°C (-3.8°F
to +211.8°F). During programming, it shows the codes and values of the parameters. The
display also shows icons according to occurring events.
