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 50°F and 131°F. Units can be ordered with an additional electrical
cabinet heater. For the cooling capacities and evironmental ratings please refer to the type plate data.
