Facility Water Maximum Inlet Pressure must not exceed 150 PSIG.
Facility Water Maximum Pressure Differential must not exceed 50 PSID.
(Pressure Differential = Inlet Pressure - Outlet Pressure)
Note
Contact us before using facility water that is above 35°C.
The facility water must meet the following conditions for the chiller to maintain
its full rated capacity.

Example:
Follow the lines.
Start with a known, e.g., facility
water
temperature.
A - go across to temperature
curve
B - drop down to determine the
minimum required facility flow.
C - Where B crosses the PSID
curve, go across to determine the
minimum required PSID.
