This R1234yf Refrigerant (340g Refrigerants) is applied to use in the auto repair plant.
1)R1234yf refrigerant is a non-ozone depleting, low global warming potential (GWP) refrigerant and R1234yf Refrigerants are also the next generation refrigerant for automotive air conditioning. It provides the same cooling comfort that consumers depend on. Freon 134a has a GWP of 1,300; Shrader R1234yf has a GWP < 1 and is therefore less harmful for the planet.
2)R1234yf is a refrigerant to replace R134a in mobile air conditioning
3)R1234yf is a gas that can change state from gas to liquid and back again.
