Application Area:

As a medium-low temperature environment friendly refrigerant, R134a is a very safe and effective alternative to R12. It is commonly used in food refrigeration equipment, automotive air conditioners, central air conditioners, dehumidifiers, cold storage, commercial refrigerators, refrigeration condensing units and other refrigeration equipment. It can also be used as aerosol propellants, medical aerosols, insecticide propellants, polymer (plastic) physical foaming agents, and magnesium alloy shielding gases. For R134a used for medicinal and medical purposes, it must be approved before use. R134a generally used does not meet the pharmaceutical grade quality requirements.

Storage and transportation (safety classification A1) :

The steel cylinder is a type of pressure vessel, so keep it away from fire, heat, and direct sunlight, store it in a cool, dry and ventilated warehouse. Handle lightly to prevent crushing, collision, and prevent breakage to the cylinder or accessories such as valve, etc.

Lubricant recommendations :

Ester lubricant (POE)

Tips: Selection of refrigerating oil for different types of equipment and different scenarios shall follow the recommendations of the refrigeration compressor and refrigeration (conditioning) equipment manufacturers, or be determined based on the equivalent design and technician requirement according to the specific conditions of the refrigeration compressor and refrigeration equipment, that is, using only the refrigerating oil that matches the equipment or its application purpose.
