Anybody have any expericence with portable water cooled chillers? I got a s/call for a 5t chiller, Manf: Temptek, M/N# CF-5W.
Problem: not cooling. this unit is hooked up to process water lines to cool the head's in a stamping plant machine.
(process water temp 70 F.) unit is cutting out on h/p at 350 psi, low side at 58 psi, (evap tank/(coil) holding glycol temp at 46 F.
I checked this system found cond. water at the proper temp 70F,
the system seemed fully charged, holds 8.8 lbs R-22 w/ sight glass, which was clear.
Now I'm not sure who has been servicing this unit or if the unit is /was overcharged, but I removed 1 1/2 lbs of ***** from this unit which showed bubbles in the sight glass, but the unit is operating within its specified range: the glycol tank will cool to whatever setting you set it to from 32 F - 68 F. The head pressure stays in the area of 250-275 psi.
I'am I missing something by chance? I have never worked on one of these before.

Thanks
JT.
