The Ultimate "No-Oil-Change" Retrofit for R-22 Systems

R-438A (MO99™) is a highly versatile HFC blend designed as the premier retrofit solution for R-22 in residential and commercial air conditioning, as well as low-to-medium temperature refrigeration. Our product is 100% Virgin Refrigerant, engineered to provide a seamless transition for legacy equipment without the need for costly oil changes or component replacements.

Why Choose Our Premium R-438A?
• Seamless Oil Compatibility: Specifically formulated to work with existing Mineral Oil (MO) and Alkylbenzene (AB), as well as POE. This "no-oil-change" capability saves hours of labor and significant material costs during retrofits.
• Near-Identical Performance: Delivers cooling capacity and operating pressures within ±3% of R-22, ensuring that your existing TXVs and system components usually remain in place without modification.
• Simplified Retrofit Process: Designed for efficiency—simply recover the R-22, evacuate, and weigh in the R-438A in the liquid phase to maintain the precise blend composition.
• Maximum Safety (A1 Rating): Classified as non-toxic and non-flammable by ASHRAE, providing the highest level of safety for technicians and property owners.
