Kooltronic Air Conditioners are required when the equipment operating temperature must be kept near or lower 
than the ambient room temperature, and/or the cabinet must be sealed from dust, fumes, oil, corrosives and other 
contaminants. This Air Conditioner utilizes a "Closed-Loop Cooling System" to ensure optimum performance of the 
installed components. 

Closed-Loop cooling seals the electronics enclosure from hostile elements in the environment. Two separate 
circulation systems are employed. The internal system cools and dehumidifies the air inside the cabinet, totally 
isolating the sensitive electronics and other components from the environment. The external system uses 
circulating ambient air or water to discharge the heat removed from the electronics.The heat is dissipated from the 
enclosure by means of the vapor compression refrigeration cycle. This takes place in a hermetically-sealed 
refrigeration system, utilizing either an air-cooled or water-cooled condenser heat exchanger. The warm air inside 
the enclosure is drawn through the evaporator coil where it is cooled, dehumidified and returned. 

Any enclosure moisture accumulated on the evaporator coil is collected in the condensate tray and released to the 
ambient air through the drain tube or the condensate evaporator. 

The heat removed through the evaporator coil is transferred by the compressed refrigerant to the condenser coil. 
Ambient air or water is then passed through the condenser coil, where it absorbs the heat and is then discharged 
to the environment. 

The cool air discharge temperature is regulated by the capacity control (hot gas bypass) valve. The unit is 
equipped with a Low Temperature Thermostat to prevent over-cooling. In applications having frequent voluntary  
heat load fluctuations, a Short Cycle Protector is recommended.
