GENERAL DESCRIPTION

 

 
 Air Conditioners are designed for applications where outside air is not available and spot cooling is 
needed. The cord connected AquaCooler Models range from 13,780 BTU/HR to 60,100 BTU/HR floor 
mount configuration to satisfy any space requirements. All models are provided with casters for 
portability. 
 
These models are thoroughly self-contained with the entire refrigeration system, water valve, 
condensate pump, fan motor and electrical components neatly arranged in a platinum texture polyester 
powder coated metal cabinet. Only power, condenser water supply and discharge and condensate drain 
piping are required for installation.The 24 volt programmable electronic controller, provides the desired 
comfort. The high counterflow efficiency design of the water-cooled condenser operation allows proper 
amount of water flow to achieve the desired high and low refrigeration system pressures. Condenser 
water is regulated by a refrigeration system head pressure actuated water regulating valve. 
 

GENERAL REQUIREMENTS

 

 
 A MINIMUM WATER PRESSURE OF 20 PSIG IS REQUIRED to actuate the water regulating valve 
and allow water to flow into the condenser coil. The condenser water temperature leaving the unit 
should not exceed 112° F. Ignoring this compliance will void the warranty on the refrigeration system.
