    Question 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

    I have great success with Isopropyle alcohol as a flushing agent.

    Isopropyle alcohol? Can you use this to flush out the compressor as well?

    Thanks MG Pony.

    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

    Yes they offer a re-processing service for the fluid and return it to you as good as new for about a third of the initial purchase price of the fluid
