Appion G5 twin
Hi there gents , I just purchased one and must say , instantly impressed! liquid recovery ratings are exactly as advertised.
I`m just wondering if anyone can share any experience pros&cons and obvious do`s & dont`s , as to get best performance and extended life from machine, thank you in advance stan
Is this thread in the right forum? The Appion G5 twin may be a good machine, but I don't think I'd be proud of the fact it took 18 hours to recover 4000 lbs. of R-134a like they state in their brochure. Almost two and a half work days, are you kidding me?
Keep an eye on the recovery tank pressure on warm days.. Other than that, its a nice little machine..
You can pump out 4000# of liquid in 1/3 that time. Getting the vapor is what takes all the time. I wouldn't try it with an Appion machine, though. IMO, if you're dealing with something that has 4000# of charge, that's like bringing a squirt gun to a nuclear war.

Last one I did ended up pulling out 185 pounds in 5 hours and pumped it back in in less than an hour. :censored: vapor.
The the little g twins are good for about 150#'s and down. I've adapted 1/2 " hoses to it, and it'll move some refrigerant. We pulled a Carrier pump-out compressor of an old 19EB, we use that for recovering large amounts of medium/high pressure refrigerants.
They have a diagram in their book for helping keep the tanks cool.

i met a guy in garland texas did a lot of 19xr work.
he made a manifold out of 2" CU and hooked up 3 g5 twins to the manifold.
he showed me pics and said basic pump laws applied so he could pull 18lbs/min
I think 1,080 lbs/hr is pretty good?
i have used two g5's at a time push pull or pull pull and have no problem getting 3-400lbs/hr liquid!
vapor is vapor!
whatever you use you gotta heat it up and let er run all night if it is a big machine!
g5 is good!
we have the HUGE trane high speed recovery machine at work!
it is heavy and bulky!
still use it on 1,000 tr or more!
that is a long time!
are you push pull or just liquid?

obviously 2 of em is 32 if you have a place to hook it up?
you should be able to push pull 185lbs
150 of it in 20 minutes and then suck on that vapor the last 35lbs or so for an hour!
of course this would be hard on a HOT day on a HOT roof!!!!!!!!!!
thanks guys , luckily I dont work on many systems w 4000lbs in them, I use a water hose trickling on cylinders to keep pressures down , Ive always played with the idea of getting a 1/2-3/4 hp condensing unit and building my own high capacity unit, think this little bad boy is gonna be great for my commercial chillers. ;)
Hey me too but I have to use 2 water hoses most of the time.
