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.Originally Posted by KnewYork

Haha. I've pumped 75 lbs in one hour using a subcooler.
On the bigger chillers we pack the 125 pound cylinders in ice and have pretty good success with it.
Last one I did ended up pulling out 185 pounds in 5 hours and pumped it back in in less than an hour.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.
Professional Member
I've read the manual.
I have my own ways to keep the tanks cool and the machine recovering without the use of ice, water, or the ways they tell you in the book.

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?
just sayin?
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!
either way!
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?

g5 push pull is 16 gpm!
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.

Seems you are still in love with those Entech guys aren't you!!!!

Too bad the EPA doesn't like the idea of home made recovery units I believe something like that is illegal unless its registered or you get caught.

I use a 5 ton water cooled condenser on mine at times, tanks never get hot.
Professional Member*
Is that a 5 ton coaxial ? That thing must get heavy.

Just pulling liquid. It had been a long time since it ran last which didn't help me. Those long recovery times are great for van organization projects!

Just ask freightshaker ,he dropped my G5 15 feet,bounced like a basketball ,and is still going strong 6months later
Its a testament to its durability , we all know it pumps pretty damn good.that model has been my favorite for awhile now .

I got a small refrigeration unit condenser with 3/8" tubing in the coil. I hook up that coil in between the outlet of the G5 and the inlet of the tank and put the coil in front of the G5. The unit blows enough air through the coil to keep the pressures down.
I've used it during the summer with good results.
