- Automotive service technicians depend on Freon™ 134a (R-134a) refrigerant, a non-ozone depleting hydrofluorocarbon (HFC) replacement for R-12.
- replaces R-12 in: Commercial stationary refrigeration systems, Chiller systems and home appliances, Existing refrigeration and AC systems
- Because many original equipment manufacturers (OEMs) specify polyolester (POE) oil for use, systems that retrofit with Freon™ 134a may require an oil change. Consult your OEM for specific guidance.
- Freon™ 134a has an ASHRAE Safety Classification of A1.
- Freon ™ 134a refrigerant meets the new AHRI 700- 2016 standard, which includes the 300 ppm limit specified for R-40
- Freon™ 134a refrigerant meets SAE J2776 purity standards.
- The shelf life of Freon™ 134a is at least 10 years under normal storage conditions
- Cylinders should be stored in a clean, dry location that is out of direct sunlight.
- Storage temperature should be below 126 °F (52 °C).
- Cylinders should be protected from mechanical damage due to improper handling.
- Freon™ 134a does not contain chlorine; therefore, it has an ozone depletion potential (ODP) of zero.
- Freon™ 134a can be used in many applications that currently use dichlorodifluoromethane (CFC-12). These include refrigeration, polymer foam blowing, and aerosol products.
- The thermodynamic and physical properties of Freon™ 134a, coupled with its low toxicity, make it a very efficient and safe replacement refrigerant for CFC-12
