R-422D (ISCEON® MO-29) is an HFC blend (R-125 / R-134a / R-600a ≈ 65.1 / 31.5 / 3.4 wt %) designed as a drop-in retrofit for R-22 in residential and commercial air-conditioning and medium-temperature refrigeration systems.

Key properties
• Zero ODP, non-flammable (ASHRAE A1)
• Cooling capacity ≈ 8 % lower, discharge pressure ≈ 5 % lower than R-22—no TXV or compressor changes required
• Compatible with mineral oil (MO) and alkylbenzene (AB); POE optional
• Net 25 lb cylinder typical (cylinder + packaging ≈ 32 lb)

Regulatory
• SNAP-approved for retrofit only; new R-22 equipment banned since 2010
• No current HFC blend production cap—service supply remains available

Environmental outlook
• GWP ~ 2 730 (IPCC AR5); interim solution pending global transition to ultra-low-GWP refrigerants (R-454C, R-466A, etc.)

The cylinder(s) may come in grey or other colors.
