RS-20 (R480A), R134A Drop In Replacement refrigerant, 24 Pounds
- RS-20 (R480A) – New R134a replacement with a GWP of 290.
- Designed to replace R134a in vehicle air conditioning.
- Also suitable for other R134a applications, see below.
- No hardware changes needed.
- Non-flammable.
- Easy to recycle.
- Similar discharge pressure & temperature.
- Equivalent cooling capacity.
- Uses same lubricant as R134a.
- Zero Ozone Depletion.
Mobile Air Conditioning
Many millions of vehicles still use R134a as the air conditioning fluid. Refrigerant leaks are common, leading to a continuing demand for service gas to maintain the operation of existing vehicles. However, authorities have introduced quotas for HFCs based on their GWP, thus progressively restricting the use of R134a and creating a refrigerant shortage that will drive up prices.
RS-20 (R480A) has a GWP of 290, which is 80% lower than R134a, and less than half that of alternatives such as R513A & R513B. RS-20 (R480A) can be charged into an existing system operating on R134a without modifications or change in lubricant. It will enable owners to maintain their air conditioning systems until they sell their vehicles or junk them.
Other Applications
In addition to mobile air conditioning, RS-20 (R480A) is suitable to replace R134a across a broad range of applications including, but not limited to:
- Refrigerated transport
- Chillers (screw & scroll compressorsa)
- Cold stores
- Supermarkets
- Cellar cooling
- Dairy chillers
- Vending machines
