   HCFCs (hydrochlorofluorocarbons) are the second generation of fluorine based gases, the original replacements for CFCs.

These products, which include R22, R123, R401A, R401B, R402A, R402B, R408A, and R409A, are categorized as having medium ODP (Ozone Depletion Potential) and medium to high GWP (Global Warming Potential). Consequently, they offer a slightly more environmentally friendly alternative to CFCs. They also often provide a quick and simple "retrofit" of existing CFC equipment. 

  As HCFCs contribute both to ozone depletion and global warming, the use of HCFCs is being phased out as part of global legislation, such as the Montreal Protocol. Some countries and regions are operating an accelerated phase out.

  Zhejiang Zhonglan Refrigerants Co.,Ltd sell a wide range of HCFC products like R22, R141b,R142b in many locations and in a variety of packages including cylinders, drum tanks and iso-tank supplies. This includes reclaimed HCFCs in some locations. We also support the transition away from the use of ozone depleting products and can offer advice on alternative products, such as hydrofluorocarbons (HFCs) and natural refrigerants, which have a lower impact on the environment.

Our factories passed ISO9001:2008, ISO14001:2004 and TS16949:2009. With scientific enterprise development, advanced production technology, solid technical assistance, overall quality assurance, excellent sales team, UISZL brand wins better and better reputation in the domestic and overseas market, and the turnover is higher and higher. We not only provide high quality products, but also the better and better service.
