More and more countries phase out ozone-depleting refrigerants and chemicals in accordance with the international agreement "Montreal Protocol on Substances that Deplete the Ozone Layer". BEST has invested in both R&D and production capacity to help countries and companies meet their commitments to this global effort by moving to non-ozone depleting alternatives.

BEST provides a variety of environmentally friendly refrigerant alternatives for air conditioning and refrigeration applications, such as R134a, R-22, R-1270, R-290, and R-600a, etc.. We also produce fuel gases (mainly MAPP gas and propane gas) and camping gases which are widely used in welding and cutting.

We use high quality raw materials and stringent quality control measures for each product we produce. Our commitment to continuous healthy, safety and environmental performance improvement is evident in the whole production and service process. You will find BEST to be a reliable supplier.
