R-422D Refrigerant
Tip: When converting from R-22, document baseline performance (amps, subcool, superheat, SST/SDT) and re-tune after charging R-422D to account for blend glide and capacity differences.
R-422D (ISCEON™ MO29) — R-22 Retrofit for AC & Refrigeration
R-422D is an A1 (non-flammable) HFC blend engineered as a retrofit for R-22 in comfort cooling, commercial refrigeration, and process cooling. It offers zero ODP and familiar R-22-class operating pressures. Designed for use with existing mineral (MO) and alkylbenzene (AB) oils (POE also acceptable), it helps reduce downtime on service conversions. Charge as liquid and follow OEM best practices for blends.
