Hi All,
I'm in the process of purchasing a recovery unit for commercial use. Does any one have any experience with any one of these three units. Which is the best for the money?
NRP Globesaver GS3700 $700
CPS CR600 $475
Appion G5Twin $660
Thanks in advance for your input.

Appion G5Twin Hands down. I teach HVAC students and we have all of the brands you mentioned and then some that shall remain nameless. Hands down in side by side the Appion G5Twin wins by almost half the recovery time of the others. Take a look at this site you may find it interesting.

I love my G5 though I don't do any commercial. Great website to with all tech. info and other info needed to register it.

We have several G5's and they have been rock solid.

Ditto G5 kicks butt! It's noisy and our recovery bottle will need twice as much ice as before, however it is well worth the money. This thing will run 500 psig and still keep pumping. I bought 5 units 14 months ago and I've had no problems. Good luck!

I have used the NRP oil less recovery unit and the G5. Both have their ups and downs. I liked the NRP because of the pumpdown feature and very dependable. The con was it was heavy to drag around. The G5 is light and smaller footprint. The only cons I have with the G5 is the noise (considerably louder than the NRP) and usually I have to cool my recovery tanks because the G5 tends to heat them up pretty fast then the recovery rate slows down considerably. Works ok when in ice bath or water to cool tanks. Maybe others don't see that problem up north but down here ambient temp + the heat added by the G5= slower recovery rate than the NRP, unless you cool your recovery tank.

Any of you G5 fans using them on r410a? I was about to pick one up at the supply house, and the rep. said the G5 wouldnt work with 410, and to go with the GS3700. I figured I would go do some research of my own first.

Never used one for 410a, but Appion says it's made for it..........

yeah, I just noticed that as well. What got me questioning though, was on that spec page, it says "N/A" on vapor recovery at 104 degrees. Out here in the Southern CA. desert, we're recovering on units in 120 degree weather(was 115 yesterday).

Just thinking out loud, but 410a at 104 degrees is at 335# if you were to recovery at the temperature and the tank were to rise just 30 degrees, (134 degrees) which I am sure is probable, the pressure would be at 500# which is the limit for the Appion unit. (and most others I suspect) The trick is to keep the tank cold in hot weather, or precool the refrigerant, then you will have not problems. I am sure that the appion is rated operating with the tank at ambient.

I picked up a 7/8 heat exchanger for refrigeration, and soldered two hose bib fittings in the ends. I discharge from the recovery unit into the heat exchanger then into the tank and run water through it to cool the refrigerant. This works very will in increasing recovery speed in hot weather.

Jim that sounds good.
How portable is your design (move from job to job), and could you post a picture.

Thanks

One of these (see attachment) it is about 14" long and weighs about 2.5 lbs complete. I put a hose bib on each end and a 1/4 mpt x 1/4 flare on the 3/3 liquid connections instead of suction gas through the center, I run water.

Total cost less than $150.00 but the results are great.

I tried to recover 410 but machine tripped on high press. Down here ambient is hot:eek:, I did notice that the recovery added a lot more heat than other recovery units i have used. The only way to do it is to cool recovery tank; like an ice bath. But I would hate to drag bags of ice on a roof since ambient at 95+ would melt that ice pretty fast. But another way i used to cool tank was to get cool water from a water hose continuously on tank that helped. All that extra work i am not a fan of.

i have a coil of 3/8 copper about 25' long with 1/4" male flares on each end. put coil in bucket of ice water and hook up between discharge and tank.


have not used it on 410 yet but it should help a lot.
