Flushing Systems.
What is the best product to use to flush a vapor compression system after burnout or for flushing a system to retrofit from R12 to R134a?
Is there a cheap, safe product for doing this that won't hurt the compressor or affect polymer oils?
Please no one recommend R11

Re: Flushing Systems.
I have great success with Isopropyle alcohol as a flushing agent.

Re: Flushing Systems.
Isopropyle alcohol? Can you use this to flush out the compressor as well?
Thanks MG Pony.

Re: Flushing Systems.
I've don it with compressors with no signs of degradation, I'd try it with a junked one and meg it after to make sure.

Re: Flushing Systems.
A flushing machine from polar pumps , it is basicaly a pump which circulates the fluid arond the system by replacing the compressor it has a refrigerated on board storage tank to prevent the fluid evaporating/ gassing off and a purge facility to enable the fluid to be remove from the system when its been flushed it cost about £3500.00 but they would come to your site and do it for you if you only have one system that needs flushing
