Here lately I’ve had quite a few questions about R-134A and 22-A Freon. So let me tell you what I know.
- R-134A is available in a 30 lb cylinder, a 12 oz can, and a 12oz can with sealer
- It is a clear product
- This product requires polyol ester (POE) lubricants, primarily for their ability to mix with HFC refrigerants
- Traditional miner oil and alkyl Benezene do not mix with HFCs and will cause compressor failures
- Automotive air conditioning system may also use polyalkaline glycol (PAG) lubricants (not typically seen in stationary equipment.)
- Equipment built for R-12 will be sized a bit too small compared to equipment built for R-134A. In order to do the same job and R-134A system will need a larger compressor and larger heat exchangers. As a result a system which is retrofit from R-12 to R-134A will have lower capacity (run longer) and will probably develop higher head pressures (not enough condenser area).
- The 30lb cylinder weighs 36.25 lbs, and has a fill weight of 30lbs
- It is about as flammable as WD40
- It has an ether like odor
- It is compliant for CA
- Comes with standard ACME threaded cap.
- No license Required
- Use up to 40% less
- Lower operating costs
- Less head pressure, extremely efficient
- Non-ozone depleting product
- Non-Toxic, Non-Carcinogen – No Long Term health Risks
- Compatible with Mineral & Synthetic (Ester & Pag) Lubricants
- Proven Results
- Classified as Pharmaceutical Grade
- Government phasing out traditional R22
- Made in USA
- Hydro Carbon Leak Detector is recommended for checking Leaks
- *This product is equivalent to 30 lbs of traditional R-22. Because this is a lighter gas you will only need to use 1oz of 22-A for every 2.5oz you had to use with traditional R-22.
Guidelines for the Pressure of 22A
Charge low side pressure to around 70 PSI. Your high side pressure should be around 230-250 PSI. Always fill from the low pressure side. It should be at about 40-44 degrees on the evaporator coil. Those are the ranges of a typical charge.
