10 hp and 15 hp Remote Air-Cooled Portable Chillers
Nominal operating parameters for remote 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.

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.

f Multiply 460/3/60 amperage by 2.0 for 208-230/3/60 amperages; multiply by 0.8 for 575/3/60 amperages.
Remote air-cooled portable chillers come standard with mounting rails. Remote air-cooled portable
chillers are charged with 25 psi (172.4 kPa/1.72 bars) nitrogen for shipping purposes.
