Chilled/hot water Piping
The minimum expansion volume for CMAF Multi-Pipe
units delivered with pump package is approximatively:
• 3% of the water content of chilled water loop
• 5% of the water content of hot water loop
Chilled water expansion tank volume (option):
Note: Maximum pressure of the circuit is 400 kPa with
pump package and 1000 kPa without.
