NOTES:

ƒMaximum acceptable flow through heat exchanger tubes is 90 GPM for two-pass and 200 GPM for single-pass systems.

ƒIn closed heating systems, GPM may increase by 10% and pressure drop by 21%.

ƒSingle-pass heat exchangers should be used only when flow rates exceed maximum acceptable rates for two-pass.
