    The turbo guard is a good purge until it breaks. That little oil pump on the newer style is $3300.00 and is a bear to change out. I can see why they get replaced with mechanical style purges.
    Synergy,

    The pump and motor can be bought separately, just change out what is needed. Also a lot cheaper that way, but still a bear to work on!

    The only time an oil pressure lubricated shaft seal - anyone's - is designed to leak, is the nominal amount of oil that you get during the run cycle. Unless that's what you're speaking of in this statement (in which case it has no bearing at all on this discussion), then I'd have to say that all you know about shaft seals is what Trane has shoved down your throat. I've seen the majority of their marketing propaganda about those horrible York shaft seals, and I know of customers at this very moment that are having shaft seals on Yorks changed once every year for some astronomically high prices because Trane has told them that they have to be changed or they'll fail catastrophically and do all sorts of irreparable damage to the machine and create havoc in the facility. It's really sort of a sad thing to see someone that has the background and experience that you have who would believe something like you stated here enough to say it in public.

    The biggest advantage to running a self contained purge in the off cycle is you don't have to baby the machine. Weather your just limping a chiller repair or you just made a repair on the fly. You can wheel it over if needed and work most of the non-condensibles to the condenser for removal and shut her down, all while continuing your work. etc etc vs standing there manually running chiller keeping just out of a surge condition to work it out. All in all they are nice to have, as far as the ragging one another thats the fun stuff. Its all part of being proud of who you and what you do!

    Like I said there designed to leak , I didnt lie mislead or tell an untruth you just addmitted it !!!!
    And during the off cycle when the seal dries out they leak even more , its the oil that creates the seal .

    If you're going to quote me on something to try and prove a point, then quote all of the pertinent information - not just the part that suits your purpose. And if you want to start running down other folks' gear, then I might find time to point out quite a few faults in the less than perfect Trane chillers, although I'd rather not because for all of their warts, I personally think Trane makes a decent machine (some better than others). You just seem to be brainwashed into the "It's hard to stop a Trane" culture and mindset, in which no one else can match up. Truth is, it ain't hard to stop one, but I've had a heck of a time getting a few started.

    what would be the point of running a purge during the off cycle?

    same as running it with the chiller on

    I've also seen mention of shaft seals leaking. Why,

    York shaft seals are designed to leak .

    That's funny Klove, that takes me way back. Took a picture years ago of a trane recp chiller that the customer had added to that saying on it. Its hard to stop a trane, but who and the h__l can start one. It looked like it was shipped that way. Customer would be steaming, Boy they hated it when that chiller went down. Because they couldn't get it back up without making a serv call.

    graham, You have to at least give York credit for installing the oil sample bottle on there chillers so we don't need to pull our own samples.

    Klove . I actually think the york low pressure chillers are pretty good , the things I dislike about them are as I have said ,, refrigerant guzzler purges , flaky leaky shaft seals and who the hells idea was it to use cork gaskets ????
    And Trane has not shoved anything down my throat re York and their shaft seals , my comments are based on personal experience . Yes I do work on Yorks to !!!!!
    Do Trane chillers have problems .....of course they do ...thats what keeps me employed .
    As far as Brainwashed ...... not a chance... like someone else on here says "its hard to stop a Trane but I make a lot of money keeping them running " and i would like to keep doing so .
