    If it doesn't leak and/or explode, who needs new? Besides, don't they work better once they've been banged around a bit?

    I made one out of scrap soft copper similar to the one in Scotts picture. It works great.

    I use a coaxial heat exchanger from a water-source heatpump that was being decomissioned. works like a hot-damn and prevents your recovery cylinder from stacking up.

    I found the CPS version on ebay.

    Some bright spark had cross threaded one of the connectors, which was easily fixed using the correct pipe die.

    I typically put cold water in a bucket, enough to submerge the coil, and by the time I have recovered 15 or so lbs form a long lineset split on a mall roof (just for example) the water is so warm you could bathe in it.

    Having tried to recover 410a previously without this device, I can tell you that this takes about 10% of the time required because it keeps the high side pressure low on the Appion, and that allows the machine to run continuously without tripping the high side switch.

    X2 on that. 95f day. Pushing 540 psi. Hooked up my CPS up, dropped it in a bucket of ice and head dropped to 280 and I could wide-open the inlet. Sucked out 24 lbs 410a in 1/2 hour. 100$ for a well made, protected, guaged, cool looking device that got me out of the heat a lot faster. Well worth it.

    I don't see the reason for having to make your own. The Molecular Transformator is great for $129.

    I went to URI and bought a 3/4 ton water cooled condenser (cupranickel) for $120. brazed on flare fittings and water hose connections. best thing ever.....run a hose to it, and another hose to drain it somewhere. I hate dealing with Ice when I can just connect a hose.

    We've got several accounts where the maintenance contract says we'll hose off the condenser in spring before the cooling season, but there's no hose bib to be found anywhere. Oooopsie.

    I make a note of it on my report forms, but so far nothing gets done. The boss dudes don't even want to acknowledge my emails or statements on our forms, LOL. Guess that would be some sort of liability issue.

    And I hate carrying more than a sort piece of garden hose on the service vehicle. But with these guys I'm with now, I've got 300' of hose. Oh well, at least I'm not getting called at 2am for some refer that went down.

    Guess there's ups and downs to every style of work.
