22-A Substitutes Refrigerant - Second generation replacement for R407c, R404a and MO99

Product Review (submitted on August 16, 2013):

At my job we have 3 20ton water chillers all running on R22. 4 or 5 times a year a line breaks and we lose all the r22 from that compressor. The latest one to lose its charge I filled with this stuff and it works great! It is a well known fact that propane is a very good refrigerant (much better that R22). Head pressure dropped from 275psi to 150 so less energy used and wear and tear on the compressor. You also need much less of this stuff so make sure you don't over charge. Ignore the few negative reviews as they are from HVAC guys who are afraid of losing out on work if people can work on their own equipment. Yes propane is flammable but your putting it into an enclosed system with NO oxygen. If you do spring a leak somewhere the propane would have to be mixed in the exact air fuel ratio and be near an ignition source at the same time. I think there are many other hazards around your home that you should be worried about!
