Product introduction

As the most widely used cryogenic environmental refrigerant, R134a is a very effective and safe alternative to CFC-12 because of its good comprehensive properties. HFC-134a is mainly used in most areas of R12 refrigerant.

Character use

No damage to the ozone layer, is currently the most countries in the world recognized and recommended use of environmentally friendly refrigerants, also is the mainstream of environmentally friendly refrigerants are widely used at present, and then add the new installation and maintenance process of the refrigeration and air conditioning equipment.

Main uses

The use of R-134a as a low temperature refrigerant most widely, because of the good performance of HFC-134a, making it a very effective and safe alternative to CFC-12, including mainly applied in most areas, the use of R12 refrigerant, refrigeration equipment, refrigerators and freezers, water dispenser, car air-conditioning, central air-conditioning, dehumidifier and commercial refrigeration, cold storage, ice machine, ice cream machine, refrigeration condensing units, but also can be applied to aerosol propellant, medical aerosol, aerosol insecticide, polymer (plastic) physical foaming agent, and magnesium alloy protective gas etc..

R134a

R-134a is currently internationally recognized as the best environmental substitute for CFC-12. HFC-134a does not contain chlorine atoms, has no destructive effect on the ozone layer, and has good safety performance (no flammable, explosive, non-toxic, non irritating and non corrosive). Its refrigeration capacity and efficiency are very close to CFC-12, so it is regarded as an excellent long-term alternative refrigerant. HFC-134a can be widely used as refrigerant in automotive air conditioners, refrigerators, central air conditioners, commercial refrigeration and other industries, and can also be used in medicine, pesticide, cosmetics and cleaning industries.

R134a is an alternative refrigerant for R12, and many of its properties are very similar to R12

The toxicity of R134a is very low. It is not flammable in the air, and the safety category is A1. It is a very safe refrigerant.

The chemical stability of R134a is very good, but because of its water solubility is higher than R22, so the refrigeration system is unfavorable, even a small amount of moisture exists in lubricating oil, will produce acid, carbon dioxide or carbon monoxide, has a corrosive action on metals, or "copper", so R134a system clean and dry more demanding. R134a has not found a chemical reaction to steel, iron, copper, aluminum and other metals. It only has a slight effect on zinc.
