Mafron R-22

Mafron R-22 is the HCFC refrigerant (chlorodifluoromethane) that powered a generation of Indian air conditioning and refrigeration — and an enormous installed base of R-22 plant is still running today. That is precisely the commercial reality this product serves: maintenance and service of existing legacy installations. Cold rooms, ducted AC plants, process chillers, and packaged units built around R-22 need genuine, full-specification gas to keep running until their planned end of life — not grey-market cylinders of uncertain composition that destroy compressors.

As an HCFC, R-22 is under phase-out in India per the Montreal Protocol schedule (servicing tail permitted). Mafron R-22 from NFIL — India's original refrigerant manufacturer since 1967 — is supplied strictly for servicing existing equipment, with AHRI 700 purity and certificates of analysis available. For new installations, we guide buyers to R-407C (closest R-22 service pressures) or R-410A equipment.

Also asked for as: R22 gas, HCFC-22, chlorodifluoromethane, monochlorodifluoromethane, CHClF₂, and in older drawings and service manuals simply "Freon 22". Mafron is the NFIL brand — if a specification names a different brand of R-22, it is the same fluid to the same AHRI 700 standard.

Where it is still in service: ducted and packaged air conditioning, cold rooms and walk-in freezers, process and water-cooled chillers, ice plants, milk and dairy chilling, bulk coolers, and older split and cassette units. Almost all of it is plant that will run for years yet — which is why a reliable service-gas supply matters more than the phase-out headline.

Two service points worth repeating. First, R-22 systems run on mineral or alkylbenzene oil, not POE — a top-up needs no oil change, but a retrofit does. Second, never top up an R-22 system with a blend (or an R-22 charge with a "drop-in"): mixed refrigerant cannot be recovered or reclaimed cleanly, it wrecks the pressure–temperature relationship your technician is reading, and it usually costs a compressor.

Order Mafron R-22 when an existing R-22 installation needs a charge after a leak repair, compressor replacement, or evaporator change — or when a facility wants genuine, traceable, certificate-backed gas on the shelf instead of whatever the market offers that week.
