    R123 carbon purge tanks

    Since Trane is no longer taking the carbon tanks back, what are you guys doing with them when they are full/out of date?
    Superheat, that must be REALLY hot.

    I always recommended to my customers to disconnect the full/out of date tank and piped the pumpout discharge directly to the rupture disc vent line. Paying to exchange that tank did nothing to help the chiller or the owner. Since Trane apparently no longer exchanges it , I'll be curious to see what the Trane techs here say. I'm thinking an awful lot of disconnected tanks are just sitting there on many of those chillers. Just make sure the vent line is piped according to the IOM so the drip leg can be checked periodically.

    I had an issue recently where the purge pumped out over 200 lbs. of R-123, there was 7 psig static pressure on the vent line from all of the liquid stacked up in there. Meanwhile, the chiller was running and there was -8 psig on the other side of the rupture disk. That's 15 psid; how the rupture disk didn't break and fill the machine with air, I'm not sure.

    There's a brace across the back of the disc. It's only rated to blow one direction, although it will break backwards if you get the pressure diff high enough. It would take quite a bit.

    From a Trane tech: The carbon tank was the technology of the time. Now, this device resides within the purge. If you are keeping the existing purge and the purge time has saturated the tank, get rid of it. There is no code that says it is required as far as I know.

    The Trane parts centers here were offering a $10 reward for saturated tanks that are returned. They do not require an exchange.

    I once opened a drip leg up and what I thought was water coming out, suddenly had a funny smell and eat the paint off of a 6 foot radius spot on the equip. room floor.

    Not true, The carbon tanks can be returned to any Trane Parts Store and Trane Parts will accept them.

    Note: Trane recommends the tanks to be changed every 3 years or 4000 purge minutes from date of installation. Not changing the tanks as recommended, will result in unlawful refrigerant venting. Tanks should not be sitting around they need to be returned to Trane Parts for recycling.

    Is there any reason you couldn't just wrap a heater around the purifier collection tank and put whatever refrigerant is in the tank right back into the chiller?
