Specifications
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.
