    Trane Compressor Leak...Is it fixable?

    Hi all,

    We have a Trane CGWD050GCONT101 Chiller in our building. One of the two circuits is down at the moment, as the 15 ton compressor (Model CSHS150J0HOF) has a rather large leak on the suction fitting, which is pretty rusty. My question is this: Is it possible to repair just the suction fitting? All the quotes we have received so far have been to replace the entire compressor, at a very large expense. I just want to know if it is even possible to repair it, as that seems like it would cost less than replacing the whole (otherwise perfectly good) compressor. The model they have quoted for replacement is a CSHA150R0*00. I have also received a quote for a Danfoss at about 2/3rds the price.

    Thanks in advance for your advice!

    -Mike

    That's what I thought, but I need to convince the guy that pays the bills Any good arguments for why a hermetic compressor cannot be repaired? My thoughts would be that there isn't an easy way to do it that I can see that wouldn't result in metal shavings or welding spatter ending up inside the shell...

    The other option one of our quotes gave was to remove that compressor, cap off it's connections, and run it with 3 compressors instead of four. Would that be a reasonable temporary fix to get us through this season, until we can afford to replace that compressor?

    I would stick with the compressor from Trane. Since there are multiple compressors in tandem on the same circuit, there is an orifice plate that goes in the suction line of the compressor. It is critical that this orifice is right or you will have oil return problems and possibly loose the replacement compressor. I'm not sure how that would work out using a non OEM compressor.

    I don't see that as a problem as long as it is done in a way that won't cause oil return problems to the remaining compressors. Also, it would need to be done in a way that doesn't affect the hot gas and suction manifolds. When you eventually replace the compressor, that orifice plate will need to be reinstalled and the piping will need to be exactly the way it was originally. In the end, it's going to cost you a lot more money than if you just replace the compressor now.

    I figured as much when it comes to the ultimate cost. I am definitely 100% for the replacement of that compressor. Now I just have to convince the head honcho. I just got a price to do the cap off and removal of the leaking compressor, and it is not far off from the replacement price. That'll definitely help my argument. I had not thought about the price of R-22 being as big a factor as it is until it was mentioned here. Yikes! Anyway, Thanks for all the advice guys...I'll let you know what we decide.

    Well, we bit the bullet. The paperwork has been signed, now we're just waiting for parts to arrive, so they can start on the compressor replacement. They are also going to clean up the 3 remaining compressors, and re-paint that joint with some epoxy-based coating of some sort. Thanks for the help guys!

    Can you post pictures of leak location?

    I'll go get some pictures on my way out, and post them tonight...It seems to be a pinhole type leak on the underside of the suction fitting on the compressor...It was pretty badly rusted. My other concern is what shape the other three compressors are in if that one was so bad.

    Here are some pictures of the leak area on Compressor 'C.' The leak itself is on the underside of this fitting, right smack in the middle.
