    United Refrigeration recovery cylinder problems

    Is anyone else getting recovery cylinders from URI that either aren't in a vacuum at all, or very little vacuum?

    I've picked up everything from 30's to 125's and seems like almost every single one has to be evacuated before use. Some the valves haven't even been closed. I've even had some that have turned my pump oil white and milky. Got a 50 today that was above 24,000 microns. One job, I had 10 125's, and lost 2 hours evacuating fresh cylinders. Every single one I've got has the shrink wrap on the valves.

    I've already complained to my branch several times, but am really getting tired of having to spend time on jobs evacuating fresh cylinders. It also makes me wonder what kind or contaminates are still in the tanks.

    This is really starting to tick me off........

    Can you switch suppliers or is that not a option?

    I may have to. I'm really just curious if it's widespread across URI.

    It seems like a lot of people don't check cylinders before use though, so maybe this is being missed.

    I don't think the branch employees have anything to do with the cylinders except to unload them from the truck and swap new ones out for used ones. I can't imagine anyone at the counter, let alone the warehouse workers at my local branch know what a micron even is.

    I always pull vacuum on a tank prior to use, unless I have no plans to reuse the juice.

    But, I have noticed a few tanks with busted dip tubes, and some under pressure from who knows what.

    On in house tanks that I question what is in them - burned oil - acid - who knows what, I will remove the tank valves and slosh mineral spirits around in the tank, and then dry it out, reinstall the valve and then evac. That had to be done cause I was working for morons at the time. Who never had the tanks exchanged.

    The other interesting thing about United is that their tanks are not listed for use with 410A. You have to get a "one shot" tank from them that is listed for the pressures of 410A.

    That may be a regional thing. In Texas, no one had normal reclaim cylinders, just the one time use ones, so If you planned on reuse, you had to illegally add a ball valve to the 1/4 fitting, cause once the tank valve closes, thats all she wrote.

    Here in Chicago - there are only the normal tanks. Ive never even see a one shot here.

    Aren't One-Use tanks only for reclaim? I had a UR employee tell me about adding a ball valve to use for recovery & recharge.

    The difference is the relief valve pressure in the United tanks is only calibrated for lower pressure refrigerants.

    There are tanks available that can handle 410A, but United has none of them except for the one shots.

    I asked (and Philadelphia is the headquarters for United) and I was told that they have not purchased any recovery tanks that can handle 410A and they are content to sell the one shot tanks.

    We have been getting high pressure rated cylinders from United that are noticeably heavier than the standard or R-23 tanks. They usually have a positive pressure nitrogen anywhere from 10 to 15 pounds and come out of the united refrigeration distribution center out of Dallas Fort Worth.
    I have gotten 125 pound cylinders that were full of rust and a fuse it did have water left inside
