4. Technical information
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. Control cabinet 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 -20°C and +55°C. Units can be ordered with an
additional electrical cabinet heater. For the cooling capacities and evironmental ratings please refer to
the type plate data.
