Head Calculations - Continued:
The previously shown example loop has a volume of 4.5 gallons. The internal thermal expansion tank is 2 liters
or .52 Gallons. The volume of the cx50 is 4.5 liters. An additional thermal expansion tank may be required for
larger loops. There are many thermal expansion calculators on the internet, the following is an example.

Minimum loop pressure is 14.5 psi, maximum pressure is 43.5 psi, and ideal pressure is 29 psi. The lowest
temperature is 44°F, the highest temperature is 131°F, the Initial pressure is 14.5 psi, and the final pressure is
29 psi.
A microbubble air separator should be installed in the loop preferably in the higher part of the loop to remove
any air in the circulation loop. Always install a water filter or wye strainer on the supply pipe to the chiller to
prevent blockage of the heat exchanger or damage to flow meter.
