Replaced R11 in low pressure centrifugal chillers. Retrofitting existing R-11 chillers to R-123 may require replacement seals, gaskets and other system components to obtain the correct operating conditions and prevent leakage.
R123 mainly uses in large, low-pressure centrifugal chillers. And replaces R11 and R113 to use as cleaning agent, foamier and refrigerant.
