NU-22B is an AHRI-700 certified, virgin A1 refrigerant built as a high-performance R-22 alternative for residential and commercial A/C systems. It's compatible with mineral oil, alkylbenzene, and POE oils, which can help simplify many R-22 retrofits without a routine oil change.

What You Get

• 25 lb factory-sealed cylinder, 100% virgin refrigerant
• AHRI-700 certified purity
• A1 – non-flammable classification
• Compatible with MO, AB, and POE lubricants
• Reliable cooling performance for R-22 retrofits

Best for: residential and commercial A/C, rooftop units, and split systems.

Please note: confirm system requirements before retrofitting and follow all manufacturer specifications and applicable regulations.

Why Purity & Certification Matter

Refrigerant purity has a direct effect on system performance and equipment life. Non-condensable gases, moisture, or residue in a charge can raise head pressure, reduce cooling capacity, and shorten compressor life. Buying a factory-sealed, virgin charge – rather than reclaimed or repackaged product of unknown origin – is the simplest way to protect the equipment you're servicing.

Frequently Asked Questions

• Is this a drop-in replacement for another refrigerant?
  NU-22B is designed as an R-22 alternative that often avoids a routine oil change, but system compatibility should still be confirmed first.
• What does the A1 safety classification mean?
  It's a refrigerant industry safety rating. This product is classified A1 (non-flammable), which describes its flammability under ASHRAE/ISO guidelines and determines what handling and installation precautions apply.
• Can this be shipped, and how should it be stored?
  Refrigerants are regulated hazardous materials and generally ship via ground freight under DOT rules. Store the cylinder upright in a cool, dry, well-ventilated area out of direct sunlight, and keep it away from heat sources.
