Refrigerant R-438A (MO99)
Refrigerant R-438A, commonly known as MO99, is a non-ozone-depleting hydrofluorocarbon (HFC) refrigerant developed as a reliable replacement for R-22 in refrigeration and air conditioning systems.
R-438A is particularly well-suited for retrofitting existing HCFC systems that utilize direct expansion (DX) evaporators and positive displacement compressors. It enables system owners to transition away from R-22 with minimal equipment changes while maintaining dependable cooling performance.
