HFCs (hydrofluorocarbons) are the third generation of fluorine-based gases.   

These products are categorised as having zero ODP (Ozone Depleting Potential) and medium to high GWP (Global Warming Potential) and so offer a more environmentally friendly alternative to CFCs and HCFCs. HFCs are used in a wide range of refrigeration and air conditioning equipment specifically designed for them, and as "drop in" retrofit gases for older CFC or HCFC equipment. HFCs are also used in selective propellant and foam blowing applications.   

A growing focus on the environmental impact of refrigerants is fuelling demand for refrigeration solutions that can provide satisfactory cooling performance with a lower impact on global warming. This is propelling environmentally friendly refrigeration solutions to the top of the corporate sustainability agenda. In addition, local legislation is increasingly targeting refrigerant gases with high GWP. 

Zhejiang Zhonglan Refrigerants Co.,Ltd offers a number of lower GWP HFC solutions, such as R134a, R404a, R406a, R407c, R410a, R507,R417a,R422d,R125,R32, etc. For new equipment purchases, we also supply a wide range of HFC alternatives. These include HC(natural refrigerants), which provide a viable, lower GWP alternative to HFCs.
