2 hp and 3 1/2 hp Air-Cooled Portable Chillers

Nominal operating parameters for air-cooled models are 50ºF (10ºC) leaving water temperature at 2.4 gpm per ton (9.1 lpm per 3.517 kW) with 95ºF (35ºC) ambient air. For 50 Hz applications, multiply capacity by 0.83. Nominal 60 Hz capacity flow rate must be maintained.

cBased on 50ºF (10ºC) chilled water supply temperature and 95ºF (35ºC) ambient air. Optional additional process pump hp (kW) reduces chiller capacity by 0.2 tons per hp (0.703 kW ref. cap. per 0.746 kW pump power).

dBased on 2.4 gpm per ton (9.1 lpm per 3.517 kW), nominal 1 pump.

eAn optional oversized process pump adds to the total rated or running chiller amperage. To find the new total

chiller amperage, subtract the standard process pump amperage from the optional pump amperage (see Figure 1 on page 16), and add it to the chiller rated or running amperage.

fMultiply 460/3/60 amperage by 2.0 for 208-230/3/60 amperages. g To convert cfm to cmh, multiply by 1.699.

2 and 3 1/2 hp portable chillers come standard with 2 1/2” (63 mm) swivel casters.
