R-134a (1,1,1,2-tetrafluoroethane) is a kind of chlorine-free atom, which does not damage the ozone layer and has good safety performance (non-flammable, non-explosive, non-toxic, non-irritating), Non-corrosive) refrigerant, its cooling capacity, and efficiency are very close to R-12 (dichlorodifluoromethane, freon), so it is regarded as an excellent long-term alternative refrigerant. R-134a is currently the best internationally recognized alternative to R-12. It does not destroy the ozone layer at all. It is an environmentally friendly refrigerant recognized and recommended by most countries in the world. It is also the mainstream environmentally friendly refrigerant. It is widely used in the initial installation and maintenance of new refrigeration and air conditioning equipment. . R134a has very low toxicity and is non-flammable in the air. The safety category is A1 and it is a very safe refrigerant.
Refrigerant R404A, alias R404A, trade names are SUVA HP62, SUVA 404A, Genetron 404A, etc. Since R404A belongs to the HFC type non-azeotropic environment-friendly refrigerant (without any ozone-depleting CFC and HCFC), it is the mainstream low-temperature environment-friendly refrigerant recognized and recommended by most countries in the world. It is widely used in the initial stage of new commercial grade fridge Re-adding during installation and maintenance. It meets the standards of the US environmental protection organizations EPA, SNAP, and UL, and meets the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) A1 security level category (this is the highest level, harmless to human bodies).
R290 (CARE 40) Propane
R290, also known as CARE® 40, is refrigerant grade propane, a natural, or "not in kind", refrigerant suitable for use in a range of refrigeration and air conditioning applications. The use of R290 is increasing due to its low environmental impact and excellent thermodynamic performance. It is non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential). It is a flammable refrigerant and therefore not suitable for retrofitting existing fluorocarbon refrigerant systems. Common Applications：Commercial Refrigeration，Commercial Refrigeration: Plug-Ins & Vending Machines，Industrial Refrigeration，Residential & Light Air Conditioning，Industrial / Commercial Air Conditioning DX Chillers
R600a (CARE 10) Isobutane
R600a, also known as CARE® 10, is refrigerant grade Isobutane, a natural, or "not in kind", refrigerant suitable for use in a range of refrigeration applications. The use of R600a is increasing due to its low environmental impact and excellent thermodynamic performance and it is now the refrigerant gas of choice in the domestic and small commercial refrigerator for sale. It is non-toxic with zero ODP (Ozone Depletion Potential) and very low GWP (Global Warming Potential).
