    rtac high temp wash

    Has anybody ever heard of washing condenser coils on a 134a machine with hot water causing refrigerant to seperate? I have not experienced this, but a coworker of mine suggested this to be a possibility. If it did seperate, why wouldn't it just mix again? 134a is not a blend anyway.

    We wash them rather frequently in the winter time to try to get the chemicals to work better for foaming and have had no issues what-so-ever. Very interesting thought, I'd love to hear their explanation/logic behind thinking that....

    r134a is a single component fluid. I'm going to bet against it separating.


    IF it were possible for it to separate as in the case of blends, running the machine would rapidly mix the fluid back together.

    Depends on the chiller, depends on the airflow offender, as to which chemical I use. In a perfect world of course I only use water. I hate to lay the nubrite to them. That only comes out through the coilgun into the worst of the worst. We have a big 30gtn and a big RTAA that chug automotive paint. They get a lot of nubrite. On the other hand we have some 2001 TS machines at an aluminum mill that were only washed with dishwasher detergent and look and flow great. Just depends. As for the original topic that sounds a little far out there. Maybe some over thinking going on.

    We are required by contract to use the foaming coil cleaner. I usually mix it really lean and spray one panel at a time from both sides at once. I've had great results this way. Rinse then repeat until the foam comes clean.

    We have a Goodway machine that we used once it cleans the surface really well but didn't penetrate into the coil. After using it I cleaned it my way and and still got a ton of dirt out of it.
