Hi Guys.
I want your opinion on what I'm telling you:
Early this morning at 05:00, started to replace a compressor, trane 60HP at a rubber factory. Its very tight there and I need to use a forklift to change the heavy compressor - about 400 KG and by 10:00 I started with vacuum after a leak test.
While the system under vacuum, I've put in two new contactors 90 amp, its a YY start. took down two 60KG ***** 22 from the van and went for a cup of coffee.
So far so good. Came back and started to fill the system with liquid gas and I cant tell you why, but after some 25 KG, I stopped and started the unit. within 20 seconds the compressor tripped on low pressure, BUT.......... the pressure in the suction line was still 80psi.
It sould not cut out so high. Checked the pressure control, OK, try again and the same, so there must be something between the suction line and the compressor. Collected the gas and open the bolts and you will never guess what I saw. A BLOCK OF ICE!!??
Very strange, I open the system early in the morning for maybe one hour, it was under deep vacuum for a few hours with temp of 35C.
No water leaks, nothing seems to be wrong but where did the water came from??????????
Sat down, had a cigarette and more Turkish coffee and my brain runs tike a gyro. Than I looked at the ***** bottle. No, it cant be. But I got up put my hand in front of the bottle, opened the liquid valve and watched my hand getting coverd with frozen *****, closed the valve and to my big surprise, my hand was wet with water!!!!
To make sure, I took a bucket with a bit of oil, put the end of the pipe in the oil, covered it and run liquid ***** into the oil.
when I took the cover off, the oil was white from the water!
So, water in *****, did you ever heard of such a thing?
Now I'm waiting for my supplier reaction to that story,
Well, you learn a new thing every day!! :)
