    York YT Average purge time?

    I am working on a York YT R123 Machine. I new it had a leak, so I pulled all the refrigerant. Perfomed a leak search. Found the leak in the releif. Replaced the relief. Evacuated the system, charged it back up. Now I have a portale purge unit on it. Should I leave the purge unit on all night? Or is there a formula to calculate how long to leave it on? There is 810 lbs in the system.

    No known formula for the time it takes a purge to remove whatever non-condenseables from a system, Far too many variables.
    As for leaving a purge on unattended, well....that my friend is truly a crap-shoot.
    Assuming your purge has some type of float to return condensed refrigerant, should it hang up and not open, it would be very easy for your purge to dump 400-500 pounds of refrigerant overnight.(Don't ask me how I know this)
    Personnaly...I would not even get a cup of coffee and leave a portable purge pumping unattended.

    Agreed, I guess I already new the answer to my question. Just really tired and trying to get this machine online.

    If you evacuated the machine before recharging, what's the reason for having a portable purge hooked up? Start it up and let the unit mounted purge take care of the residual n/c's.

    It would have been a better idea to use the portable purge on the recovery tank. Never had that much air from recovery tank to cause surge. If head goes a little high on start-up, keep vanes closed until onboard purge removes air.

    I agree with the other previous posters ....but why not really solve your problem and scrap the POS York refrigerant guzzler purge and put a Trane purifier on it ???

    He apparently solved his problem by fixing the leak.

    It's always been my philosophy that people tend to run things down simply because they don't understand them. Other than the fact that it doesn't work during the off cycle (which is admittedly a downside), the turboguard purge is a very good system. Been around for years, don't give a ton of trouble, just works. Can't ask for much more than that....

    I would ask that it does run during the off cycle and doesnt guzzle refrigerant . And i do understand how the Turboguard works .

    If your chiller is leaking so much that your purge needs to run in the
    "OFF CYCLE" wouldn't it just be better to fix the leaks?

    I just installed a purifier purge on 2 YT's. Not only do they look good they work great to.

    No need to rest your case - I've installed purifiers and skyguards on all sorts of low pressure machines. They do work well. But that doesn't mean the turboguard isn't a good design or that it doesn't work well - it's simply different. If you'd like we can talk about why the purifiers had to have a maximum pumpout timer incorporated into their design (they ain't perfect, either). I don't recall one of those "refrigerant guzzler" turboguards ever pumping a couple thousand pounds of refrigerant into the floor......

    Purifier Purge

    I have to go along with other tech's about this thread. If you evacuated the chiller to a proper level prior to putting the charge back in and get the air out of your recovery system hoses, your purge requirements should be almost 0. Unless your recovery system has a problem. While I agree York's purge maybe decent, Trane's is a lot better as long as the heat exchanger canister remains clean. If the machine has a moisture problem then it doesn't take long for the exchanger to become fouled. But then again if you have moisture in the chiller, no purge will help. As seen by the vice-president in charge of looking through the window (ie) sightglass. Anyway my vote goes to Trane.-Geo
    Once in a while everything falls into place and I am able to move forward, most of the time it just falls all over the place and I can't go anywhere-GEO
