We got a new account with a local meat market. They had a shorted to ground compressor on the initial call for their big display cause. Got a new compressor. Went through the whole process, replaced, worked for a week....shorted out again.
Turns out the thing was packed with acid....flushed it out on the first go around with new driers etc...but apparently not enough. So we through a new compressor in there...cut the 2 evaps loose, isolate lineset, flush all components in condenser etc. Just clean it up really good. New compressor put in with driers...all is good. Has run great since. Unit is a pump down system...maintains 35 deg box temp, pumps down to around 5 psi and shuts off.
I just dont want to lose another compressor and since its lasted twice as long this time around I am pretty sure I got it nailed with just cleaning the system up.
However I checked it today and, although it was working well, the hot gas line off the compressor seemed extra HOT....put a probe on it, running at 225-235 degrees. I always though 225 was max before stuff starts breaking down and burning up, can I sleep easy tonight?
Since the last compressor it has been working fine. Good system charge. Both valves maintaining around 10-15 superheat...one valve hunts a bit but not enough to cause problems.
Operating pressures are around 30/230. 2 Condenser fans on seperate cycling controls...kick in at oh around 245 on the first fan annnnd....like 270 on the second? Thats from memory, dont hold me to it.
Its running 22.
