REFRIGERANT GAS MAXREF R-22

Description

Applications & Phase-Out Status

• Widely used in residential and commercial AC units, heat pumps, and refrigeration systems due to its effective cooling capabilities

• Production and use are being phased out globally under the Montreal Protocol and regional regulations:

  • 2010: Ban on new equipment using R‑22 in many regions (e.g., EU, U.S.).

  • 2020: Full ban on production and import in the U.S.—only reclaimed stocks may be used for servicing .

  • 2030: Global elimination of HCFC production, including R‑22 .

Environmental & Regulatory Impact

• Contains chlorine, contributing to ozone depletion and classified as environmentally harmful

• High GWP adds to climate change concerns, prompting transition to greener alternatives like R‑410A, R‑454B, and HFO-based blends

Safety & Handling

• Toxicity: Low acute toxicity, but high concentrations can displace oxygen, causing asphyxiation and possible cardiac arrhythmia.

• Exposure Effects: Rapid release may cause frostbite; inhalation may cause respiratory distress

• Transport Classification: UN1018, Class 2.2 (non‑flammable gas)
