  • Page 4: Settings

    4. Settings 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.

  • Page 5: Functional Principle

    5. Functional principle The cooling unit for industrial enclosures works on the basis of a refrigeration circuit consisting of four main components; a compressor, an evaporator, a condenser and an expansion device. The circuit is hermetically sealed and R134a refrigerant circulates inside it (R134a is chlorine free and has an Ozone Destruction Potential [ODP] of 0 and a Global Warming Potential [GWP] of 1430).

  • Page 10 Applying supplied tight tape Condensate management: High humidity and low temperatures inside the enclosure can lead to condensation on the evaporator. Condensate that flows back into the enclosure can damage sensitive control electronics. The integrated condensate evaporation of the cooling unit releases the condensate to the environment. If condensate formation is too great, additional condensate can drip into an overflow trough, which then drains off...
