The EMERSON rep was 100% right. It is impossible to remove moisture from POE oil. I know, we have tried in the lab. The oil must be changed. The minimal open time is 100% correct too. POE will wick moisture from the air at an alarming rate. It is extremely hydroscopic (sp). This is why the compressors are shipped with plugs and about 5 psi of dry air.

Knew it was a Trane, red compressor!

Seen this in action. Most of the pipers where I work love their rosebuds. Find a leak in a unit during test, they will burn the hell out of everything around it while fixing it. Really POs everyone down the line. I normally get stuck fixing pipe insulation. I have been trying to fix the leaks myself but I don't have the skills of people doing that type of work 24/7 for years.

it will show lower then what the system is actually at. after it has been running for a while i will close the core tool that has the micron gauge on it. then im readings furthest from the pump.
