⚙️ About R-422B (NU-22):

R-422B is a non-ozone depleting HFC refrigerant blend engineered as a direct drop-in replacement for R-22 in many air conditioning systems. It offers excellent compatibility with existing components and oils, reducing the need for major modifications during retrofit.

🔧 System Note:

R-422B may have slightly reduced cooling capacity compared to R-22. Expect slightly longer compressor run times, but benefit from long-term operational stability and reliability.

🧊 Applications:

  • Residential and light commercial air conditioning systems
  • Heat pumps and packaged rooftop units
  • Any compatible system originally designed for R-22 refrigerant

🛠️ Application Method

  1. Ensure your HVAC system is specifically designed for R-32 refrigerant.
  2. Wear appropriate PPE and work in a well-ventilated area due to mild flammability (A2L rating).
  3. Connect your charging hose to the cylinder’s left-hand threaded valve using a compatible adapter if needed.
  4. Charge the system carefully according to the manufacturer's specifications and pressure guidelines.
  5. Once finished, tightly close the valve and store the cylinder upright in a cool, dry location.

⚠️ Warning: R-32 is not a retrofit gas. Use only with systems that are approved and labeled for R-32. Improper use may result in damage or hazards.
