R402B HCFC refrigerant gas

R402B (HP81)

R402B, also known as HP81, is an HCFC blend with a small amount of hydrocarbon included to improve mineral oil compatibility. The blend is designed to be a retrofit replacement for R502 in medium temperature refrigeration applications. The discharge temperature of R402B is higher than R402A so more suitable for colder climates.

Common Applications

 Commercial Refrigeration Industrial Refrigeration

Retrofit Information

Replacement for: R502
Retrofit gas or design for new equipment? R402B is suitable as a "drop-in" retrofit gas for R502.
Other alternatives / replacements: R422A, R428A, R438A
Compatible lubricants: MO, AB

Environmental Impact

Ozone Depletion Potential (ODP) 0.03
Ozone Depletion Potential (Rating)
Global Warming Potential (GWP) 2416
Global Warming Potential (Rating)
HCFCs contribute both to ozone depletion and global warming. The use of HCFCs, including R402B, is being phased out according to the schedule set out in the Montreal Protocol therefore we recommend that you consider alternative solutions.

Safety Information

ASHRAE Safety Group (2013) A1
ASHRAE Flammability No
ASHRAE Toxicity No
