Microprocessor controls calculate the most efficient time to purge noncondensibles. Many times more efficient than thermal purge units on the market. MiniPurge portable purge unit temporarily connects to chillers and storage tanks charged with high or low pressure refrigerants and rapidly eliminates noncondensibles. Unit is ideal for supplementing thermal purge units during seasonal start ups on R11 or R123 chillers. A 0.5hp oil-less compressor draws refrigerant vapor, pumps it through a condenser, and compresses it in a stainless steel purge vessel.
Condensed refrigerant is forced back to the cooling system or recovery tank.
When pressure rises to a certain point, noncondensibles are discharged with virtually no loss of refrigerant.
