Drawings and Specifications

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.

Based 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).
Based on 2.4 gpm per ton (9.1 lpm per 3.517 kW), nominal 1 pump.
An 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.
Multiply 460/3/60 amperage by 2.0 for 208-230/3/60 amperages.
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.

To convert to cm, multiply by 2.54. Add to height dimension based on mounting options.
Weight is for standard chiller. Some optional features will increase weight. Multiply lbs. by 0.454 to calculate Kg.
Operating weight is with a full 6-gallon (22.7 liter) reservoir tank of water.
