The Reliable "Drop-In" Replacement for R-22 Systems

R-422B (NU-22B™) is a high-performance HFC blend designed as a seamless "drop-in" replacement for R-22 in existing residential and light-commercial air conditioning and medium-temperature refrigeration systems. Our product is 100% Virgin Refrigerant, providing an easy, cost-effective solution for maintaining legacy infrastructure without the need for hardware overhauls.

Why Choose Our Premium R-422D?
• Exceptional Performance Match: Offers operating pressures and cooling capacity within ±5% of R-22. This precision ensures that existing TXVs and system components operate at peak efficiency without requiring adjustments.
• "No Oil Change" Compatibility: Specifically engineered to work with traditional Mineral Oil (MO) and Alkylbenzene (AB), as well as POE. This eliminates the labor-intensive process of oil flushing during retrofits.
• Lower GWP Solution: With a GWP of ~1,810 (IPCC AR5), R-422B offers a more environmentally friendly profile compared to other R-22 retrofits like R-422D (GWP ~2,730).
• Maximum Safety (A1 Rating): Classified as non-toxic and non-flammable by ASHRAE, providing the highest level of safety for technicians and building occupants.

Key Specifications
• Net Weight: 25 lbs (Total shipping weight approx. 32 lbs).
• Purity Level: 99.9% Virgin Grade – Fully meets AHRI-700 standards.
• Application: Ideal for residential split systems, light-commercial package units, and medium-temperature refrigeration.

Regulatory & Compliance
• SNAP-Approved: Fully approved by the EPA as a retrofit fluid for existing R-22 equipment.
• Stable Supply: As an HFC blend, R-422B remains a reliable service fluid for the maintenance market as the industry transitions toward next-generation ultra-low GWP alternatives.
