Product Overview
R32 (Difluoromethane) is a next-generation HFC refrigerant widely adopted as a low-GWP alternative to R410A in residential and commercial air conditioning systems. It is a colorless, non-toxic gas with a faint ethereal odor, offering excellent energy efficiency and high cooling capacity. R32 is chemically stable and compatible with most common metals used in modern HVAC systems.
R32 is increasingly becoming the refrigerant of choice for new air conditioning equipment, as it delivers superior thermodynamic performance while significantly reducing environmental impact compared to traditional HFC refrigerants.
⚠️ Important Safety Note: R32 is classified as A2L (mildly flammable) under ASHRAE safety standards. It requires proper handling and should only be used in systems designed for A2L refrigerants. R32 is NOT suitable for retrofitting into R410A systems without appropriate safety modifications.
