4. Settings

The cooling unit is intended to be used as a complementary accessory to larger industrial equipment,
and 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. The cooling unit can dissipate large quantities of heat from electrical enclosures into
the ambient air and at the same time reduce the internal temperature to below that of the ambient air. The unit
works without problems in extreme ambient conditions (e.g. dusty and oily air). The operating temperature
range is b20°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.

5. Functional principle

The unit functions on the principle of the compression refrigerator. The main components are: refrigerant
compressor, condenser, choke and evaporator. these four components of the refrigerant plant are connected
with each other by pipes to form a hermetically sealed system in which the refrigerant (R134a)
circulates. R134a is chlorine free and has an Ozone Destruction Potential [ODP] of 0 and a Global Warming
Potential [GWP] of 1430.
