R152A Applications:
R152A (1,1-Difluoroethane) is a versatile refrigerant with a low GWP of just 124, making it a more environmentally friendly option compared to traditional refrigerants like R134a. While it shares similar operating pressures and volumetric cooling capacity (VCC) with R134a, it is favored in certain applications due to its lower environmental impact.
Refrigeration Systems: Suitable for large chillers and specialized systems like heat pipe finned heat exchangers, R152A offers high cooling efficiency in medium and large-scale operations.
Aerosol Propellant: R152A is also commonly used in gas dusters and various retail aerosol products due to its compliance with strict volatile organic compound (VOC) requirements.
Heat Pump Systems: An excellent alternative to R134a in systems requiring lower GWP refrigerants, without sacrificing performance.
Despite its flammability, R152A remains a viable alternative to higher GWP refrigerants, offering a balance of performance and environmental safety.
Packaging and Shipping: Available in a range of packaging formats, including canisters and ISO tanks. We provide flexible packaging solutions to meet your specific needs.
Why Choose Us?
We offer top-grade R152A refrigerant with high purity, competitive pricing, and reliable delivery. Our product ensures both efficiency and environmental compliance, making it the ideal choice for a wide range of applications.
