QBS Series chillers are air-cooled, industrial units with cooling capacity up to ½ ton and are available in 115/1/60 or 230/1/60 power supply. The all non-ferrous fluid (water) circuit is corrosion resistant and includes a peripheral pump, insulated stainless steel tank (unpressurized), and copper evaporator immersed in the tank. Designed for indoor use, QBS Series chillers are constructed of powder-coated steel, compact in size, and with the optional wheel kit they are especially easy to move from one application to another. The standard electronic controller maintains the outlet fluid temperature, manages the operation of the fluid pump and refrigerant compressor, and displays alarm conditions.
