R454B

PREMIUM HVAC REFRIGERANT

R454B REFRIGERANT GAS

22 LB (10 KG) CYLINDER

Next-generation, lower-GWP refrigerant for compatible residential and commercial air conditioning and heat pump systems.

R454B 22 LB refrigerant cylinder and packaging - reference product

Advanced HVAC Cooling Performance

R454B, also known as R-454B, is a next-generation HFO/HFC refrigerant blend developed for modern air conditioning and heat pump equipment. It offers a lower global warming potential than R410A while delivering comparable cooling performance in systems specifically designed for R454B.

R454B is composed of R32 and R1234yf and is classified as an A2L mildly flammable refrigerant. Its thermodynamic characteristics make it suitable for modern residential, light commercial, and commercial HVAC applications.

With zero ozone depletion potential and a GWP of 466 under IPCC AR4, R454B offers approximately 78% lower GWP than R410A. It must be used only in compatible equipment and serviced using approved A2L procedures.

03 / Recommended Applications

Example of R454B compatible central air conditioning equipment

01 — Residential Air Conditioning

For compatible central air conditioning systems and residential cooling equipment specifically designed for R454B.

02 — Heat Pump Systems

Suitable for approved modern heat pumps providing residential and commercial heating and cooling.

03 — Split & Mini-Split Systems

Used in compatible ducted, ductless, mini-split and multi-split HVAC equipment manufactured for R454B.

04 — Light Commercial HVAC

Supports compatible packaged and split-type air conditioning equipment in commercial buildings.

05 — Direct Expansion Chillers

Applicable to approved direct-expansion chiller systems specifically engineered for R454B operation.

04 / Professional HVAC Use

R454B is developed for new-generation cooling and heat pump systems as a lower-GWP alternative to R410A in equipment specifically designed for this refrigerant.

Technicians should verify the equipment nameplate and manufacturer instructions before servicing or charging systems.

Professional work requires approved A2L-rated recovery equipment, suitable leak detection, proper ventilation and applicable safety procedures.

Important: R454B is not a direct drop-in replacement for R410A in existing equipment that has not been specifically approved for R454B.

Safety & EPA Compliance

R454B is classified as A2L, meaning mildly flammable. It requires appropriate professional handling, approved tools and compliance with applicable regulations.

  • Use only in equipment approved for R454B.
  • Keep away from sparks, flames, heat and ignition sources.
  • Store cylinders in a cool, dry and ventilated area.
  • Protect cylinders from physical damage and excessive heat.
  • Use tools suitable for A2L refrigerants.
  • Follow the Safety Data Sheet and equipment instructions.
  • Recover refrigerant properly; do not intentionally vent it.
  • Comply with EPA Section 608 and applicable regulations.

Purchaser Notice: Customers must satisfy applicable EPA refrigerant purchasing requirements, including relevant technician certification or permitted resale conditions.
