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 and evaporated in the condensate
evaporator tray and released to the ambient air by the condenser blower. If latent heat exceeds 25% of the total
cooling capacity excess condensate is released to the ambient through the drain tube.

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 unit is equipped with a Low Temperature Thermostat to prevent the evaporator coil from freezing. A high
head pressure switch is standard on this unit and prevents the evaporator coil from freezing under low ambient
temperature. The crankcase compressor heater allows the unit to start with an ambient temperature of 0ºF. In
applications having frequent voluntary heat load fluctuations, an optional Short Cycle Protector is recommended.
