I service Environmental test chambers These use single stage or cascade refrigeration and are capable of producing -100F temperatures controlling at +/- 1 degree ( cascade)
I have a customer who has a water cooled system and was using well water for their water cooled condenser which is so acidic it "ate" through a copper fitting on a heat exchanger and allowed water to enter the system
I will have to replace the scroll compressor, receiver, and a number of parts in order to be sure this system will run reliably as some of the testing done in these systems are prototypes and worth hundreds of thousands of $$
I can remove the water content by using L2 at a high volume heat strips on the components and pressure along with my magnet tool to open any valves then evacuate this for days etc and hope the H2O is gone but there is still oil in this system that is contaminated that is the worry I can use a flush and I have access to gallons on Isopropl alcohol but how you I know all the oil has been removed? do I have to flush every valve, etc ? I am worried about any remnant water or oil plug that would or could happen while running and render the test useless Suggestions? Is there better way?
Thanks!!
