R-422D (MO29) is a reliable, non-ozone-depleting refrigerant engineered as a direct replacement for R-22 in existing air conditioning and refrigeration systems. It delivers dependable cooling performance while allowing for a smooth and cost-effective retrofit process.
Designed to work with mineral, alkylbenzene (AB), and POE oils, R-422D eliminates the need for an oil change in most R-22 systems. This significantly reduces downtime, labor costs, and system modification requirements — making it an ideal solution for HVAC contractors and facility managers upgrading legacy equipment.
R-422D helps extend the life of existing systems while meeting modern environmental standards, offering a practical and compliant alternative to phased-out R-22.
R-422D, commonly known as MO29, is a non-ozone-depleting HFC blend engineered as a direct replacement for R-22 in air conditioning and refrigeration systems. It delivers dependable cooling performance with minimal system modifications.
