Advantages of low charge system-a] Reduced Refrigerant Charge .

b] Can be operated like domestic AC/ Refrigerator.

c] No requirement of opening & closing of valves during start / stop of the system.

d] 100% Safe against liquid stroke & subsequent failures.

e] Suitable for PLC / SCADA operation.

f] Surge Drum can be used as Low Pressure Receiver
