2002-05-01· The GPM/ton rates you are talking about are "rule of thumb" numbers. Typically for chillers systems, 2 GPM/ton is usually the evaporator flow and 3 GPM/ton is usually the condenser flow. These rates came about because they correspond to the temperature change of the water in the system. The 2 GPM/ton evaporator flow rate is a system with a 12 degree delta T (i.e. 44 degree supply water and …
