I'm currently working offshore on a pipe lay ship, our provision refrigeration plant has a leak that we are searching for.The system is charged with Unicool R-507 refrigerant. The only test equipment i have on board the ship is a unitor dye tracer fluid and uv light. These might be stupid questions but I don't have many KG of spare refrigerant onboard and i need to find the leak.
First off, with the tracer fluid that is in the oil - Will that pass through the oil separator so we can see leaks in condenser/evaporator lines or does the oil seperator take the tracer fluid out of the refrigerant with the oil so it can only help for looking for leaks on the compressor itself?
Second, If i was to purchase a electronic leak detector, what would i need to purchase that works with 507 refrigerant? Im getting mixed results on the internet and im not sure what I need.
Am i correct in saying R507 is a blend between R0143A and R125, both which do not contain CFC's or HCFC, so a halide leak detector would not work with this?\
Let me know if im way off on this..hahah....Im just desperate for some help here now because i couldn't find a leak with soap and water or the tracer fluid and uv light.
