So I am investigating alternate affordable recovery unit options. As we all know, the G5 works but is not quite built to last, and Appion does not support our kind. Although I am not sure there will be many other manufacturers who do, I am certian that there is a better preforming, more durable oiless unit out there that is capable of running R600. I already have several units on my list and plan to get in touch with the manufacturers tomorrow to find out the materials of all the components of each. I know Teflon, Viton, and nylon components are a plus, what other materials are suitable for contact with butane? 100% resistance is a must, as well as the capability to pull a deep vacuum. What other features/capabilities should we be looking for? Thanks to anyone who can provide some input, I know it will hugely benefit the closed loop community to find a proper non disposable recovery pump.

Hokay. In search of a replacement as well, as I constantly need to know the best options for my caregivers.

Here are the better options I've found..

:::The Pneumatics:::

First, upon Googling "R600 Recovery Pump" I find these bad boys...

The Galaxair

"...liquid phase and gas phase whose vapour tension
does not exceed 15 bar with 20°C."

Which (I believe) is similar to the one GW suggests..

The Haskel

I like the Haskel... Both of these require a pretty badass compressor.. Which needs to be included in to the cost/wear analysis etc..

Next we have

:::The Electric Motor Driven:::

The obvious first option.. I have heard these AREN'T oilless? Also, it doesn't specifically list R600.

The Caresaver

Next is one I found through the grapevine.
I have heard about Emotek incorporating a new pump, similar to this one, in their new model.

Until they have one available to the public, I introduce our next option

The Reftec Handivac

I've heard claims the seals are Teflon (have yet to double check) and it's oilless, operating at .75hp. They make custom units and have some that are "built to NEMA 7 Code with explosion proof electrical box, wiring, piping and motor housing"

Weeee! I hope the experts will chime in on this one!!

I know reftec makes some all in one units that are pneumatic. That is what emotek is working on with reftec.

The caresaver isn't oilless, but maybe using a cold trap after the recovery pump might help along with filtration?

The handivac isn't up to the rigors of what we do

I am curious about this myself, as I thought r-600a was what we were looking for for solvent handling capabilities. I am looking for a recovery system for Distilling my Butane and storing in LP5.

Maybe this would be a bit better with the over flow protection? I heard this was necessary regardless of which recovery pump you are using. Any insight would be helpful.

Yes, I saw how quickly these ran with GW.. Still not listed as R600 compliant.

Anyhow on the Emotek rant...
This thing doesn't look like a pneumatic recovery pump.

It looks like a modified version of the HandiVac or similar.

EDIT Read the comments..
"Emotek Labs - That pump is for testing joe..."

the cps tr-21 isn't any better than the appion.

Emotek is using a variety of recovery pumps with limited success. They are working with reftec on a pneumatic pump, but I'm unsure of the details. Possibly a detuned setup that doesn't require the power like the haskel.

Has anyone besides GW tried the Haskel?

Are the Galaxair and the Haskel basically the same?

[icdog]

I did a search for portable flammable vapor recovery pump and came up with these, do they look useful?

These guys say they use butane, any idea what recovery unit they use?

Right on so recovery machines rated for r600 are super pricey then? like several thousands of dollars?

Thanks icdog & IB, those links are solid.. I think those Welsch pumps were vacuum pumps that can handle butane and other harsh solvents in a lab setting, and then the recovery machines convert liquid solvents back to gas or vice versa I believe.

I was hoping that something under $1000 could be picked up for R600 recovery, ie Distilling Butane.

anything under a grand is going to have a finite life. consider a cost of doing business. pneumatics are a great way to go if you are doing volume, have the power requirements, and the money.

I doubt we are ever going to see anything that is reasonably price and butane certified.
