Closed Water Loop
The water chiller is designed as a closed water loop system with an expansion tank. The
expansion tank is pressurized in accordance with the volume of the entire system volume
(including installation).The expansion tank balances temperature swings and related system
pressure of the water loop. In case the coolant temperature rises the expansion tank takes in the
expanded volume of the coolant and if the coolant temperature falls the stored volume will be
released back into the loop again.
Advantages of a closed water loop system are:
-
No top up or refill required, due to no evaporation of the coolant
-
No dirt or algues in the coolant
-
No cleaning required of the tank
-
Reduces weight of the chiller
