Summary

Low pressure chillers are typically centrifugal chillers charged with R11 or R123 refrigerants, operating under a vacuum in the cooler section and a discharge pressure of approximately 0.75 kg/cm2. Any leaks will suck in atmospheric air and moisture and hence such chillers are factory fitted as a standard with a purge unit that collects and purges these contaminants back to the atmosphere.
