Available in 25lb cylinders, Choice R-420A is designed to run in refrigeration, and automotive applications.
Designed to Perform
We designed R-420A to have a nearly identical pressure-temperature (PT) relationship as R-12. This is a key factor in retrofitting without significant deviations in general operation and metering. With R-420A, there is no unit modification needed -saving you time and money.
Consistent Temperatures
Many R-12 alternatives on the market have 3, 4 and even 5 separate refrigerant components that comprise the blend. Each of these components have a unique PT curves that can vary from one another widely. This is known as temperature glide, and glide is a big problem. Glide causes inconsistent evaporator temperatures, resulting in performance degradation .
This is why we designed R-420A to have only 2 refrigerant components and the lowest temperature glide of the leading R-12 alternatives.
Compressor Friendly
We’ve packaged R-420A with a proprietary lubricant, designed to facilitate oil return to the compressor.
