Water-Cooled Portable Chillers
Nominal operating parameters for water-cooled models are 50ºF (10ºC) leaving water temperature at 2.4 gpm per ton
(9.1 lpm per 3.517 kW) with 85ºF (29ºC) tower water.
For 50 Hz applications, multiply capacity by 0.83. Nominal 60
Hz capacity flow rate must be maintained.
