R454B is a lower-GWP refrigerant blend used in newer HVAC equipment. Its A2L classification means service practices differ from traditional A1 refrigerants.
System matching
Equipment designed and approved for R454B
Choose refrigerant only after checking the equipment data plate,
manufacturer documentation and all applicable service requirements.
01
New-generation air-conditioning systems specifically labeled for R454B
Confirm the equipment manufacturer explicitly approves R454B before charging or servicing the system.
02
Heat pumps engineered for approved A2L refrigerant operation
Confirm the equipment manufacturer explicitly approves R454B before charging or servicing the system.
03
Additional applications specifically approved by the manufacturer for R454B
Confirm the equipment manufacturer explicitly approves R454B before charging or servicing the system.
Service guidance
Match the refrigerant, equipment and service method.
Every refrigerant system has defined pressure, lubricant, material and
safety requirements. Verify the equipment specification before a
cylinder is opened or connected.
R454B is an A2L refrigerant and requires equipment, tools and procedures suitable for mildly flammable refrigerants.
Do not charge R454B into an R410A system unless the equipment manufacturer specifically approves that conversion.
Follow all ventilation, ignition-control, leak-detection and service requirements applicable to A2L refrigerants.
Package and handling
Packaged for controlled professional handling.
