    Centrifugal Chiller Rebuild

    Re-gasketing a 1984 Trane CVHE032 with the original UCP1 controls. We're doing an economizer flange upgrade on this thing, too. As you can see from the 1st and 3rd pictures, there's not much room to work in this place, and the whole ceiling is covered in that awful spray-on fireproofing material. I'll post more pictures as the job progresses.

    I thought it was still Classic Black panel in 1984. Like on the chiller next to it in the last pic. Anyhoo, thanks for sharing.

    1984 was still the classic black panel, which I refer to as UCP1. A lot of people call the one that came after it UCP1, though.

    Great Pics. Don't you love how they never give you enough room to work in the chiller house and boiler rooms. Darn Architects always shave space in the mechanical spaces.

    Good work.

    What's really sad is that they had no good reason to here. These chillers are up in a penthouse on the roof. The building is 12 stories tall. Another 6 inches would not have killed them. C'est la vie. Having to transfer each piece twice just to get them off of the chiller makes for an interesting job.

    I wasn't in on the motor replacement job, but those guys did a pretty good job with it, considering the inherent difficulty of the site.

    Looks like a good job. Did the motor burned up or is just inboard bearing replacement?

    The one that I'm working on right now had leaks all over the place. Got in there and found the journal bearing oil seal needed to be replaced anyway.

    The chiller in the 2nd set of pictures had a burnt motor.

    Update: My camera phone broke, so no more pictures

    Got everything put back together now. Did an air-run on the machine with the suction elbow off. Final leak test, then I put the machine on a vacuum and pulled it down to 300 microns in a matter of a few hours. Turned off the pump, going back tomorrow to check if the vacuum rises. If not, I'll start charging 550 lbs. of R-11 and repair the insulation I had to take off. Almost there!

    Cool pix. How did the flange change out go? Gotta love tight spaces.
