R134a Refrigerant Gas

R134a refrigerant gas, chemically known as 1,1,1,2-Tetrafluoroethane, is a hydrofluorocarbon (HFC) refrigerant. It offers outstanding environmental performance and refrigeration efficiency, making it the preferred replacement for R12 refrigerant. Its CAS number is 811-97-2, UN number is 1078, and it is classified as a non-flammable, non-toxic gas under Class 2.2 of dangerous goods. Product attributes include being a colorless, odorless gas with stable chemical properties-non-combustible, non-corrosive, and extremely low toxicity. It has an ODP value of 0 and a GWP value of 1300, meeting global environmental regulations and finding widespread application across multiple refrigeration sectors.
Core parameters include a boiling point of -26.1°C at standard atmospheric pressure, a critical temperature of 101.1°C, a critical pressure of 4.06 MPa, and a saturated vapor pressure of 0.66 MPa at 25°C. Purity is ≥99.9%, moisture content ≤0.001%, and evaporation residue ≤0.01%.

Functionally, R134a refrigerant gas offers high cooling efficiency, precise temperature control, and low operational noise. It adapts to various refrigeration systems and exhibits excellent compatibility with polyester-based refrigeration oils, effectively extending compressor lifespan.
Application scenarios include automotive air conditioning, household refrigerators, commercial refrigeration equipment, industrial refrigeration systems, and foam plastic blowing agents. Regarding customer collaborations, we supplied R134a refrigerant gas to an automotive manufacturer for assembling air conditioning systems in their 500,000-unit annual passenger vehicle production. After adopting R134a refrigerant gas, the automotive air conditioning system achieved a 20% increase in cooling speed, operated odor-free and leak-free, and reduced energy consumption by 15%. The product passed EU automotive safety certification and was successfully exported to the European market. Additionally, we supplied R134a refrigerant gas for a cold chain storage project at a food processing enterprise, ensuring food freshness at -18°C with a system operational stability rate of 99.8%.

First, it is environmentally friendly and safe, posing no ozone depletion risk with low toxicity for secure and reliable use; Second, stable refrigeration performance, maintaining effective cooling across a wide temperature range and compatible with various refrigeration equipment; Third, mature production processes, consistent product quality, high purity, and low impurity content, effectively reducing system clogging and wear; Fourth, low replacement cost, directly substituting R12 refrigerant without requiring major system modifications, making it highly favored by enterprises.
