>You need 40 scfm of clean air for maximum performance, which means a refrigerative drier, a receiver, and a coalescing filter to clean up the air

Are these absolutely needed to run the Haskel? I remember looking up the driers for another business and they are 1000's to purchase.

The one on the bottom says r600a.

This may be a dumb question but wouldnt a compressor/condenser from an r600a refrigeration system compress and condense the butane back to a liquid? Im assuming that it probably would not provide enough pressure in the out flow to fill a pressurized recovery tank though. But still I'm sure you could get a pretty big compressor since I believe there are commercial refrigeration units in some parts of the world running on r600a. Maybe one of those, followed in line by a pump capable of pumping the butane as a liquid back to the tank. Just an idea...

Ya pretty sure that is exactly what the caresaver is. But it's not oilless. A lesson I learned the hard way.

Pneumatic is next on my list.

Actually the least complicated design of all the recovery pumps, but the need for a large clean air supply certainly adds to the complexity.

The Haskel is just two cylinders and pistons sharing a common rod. One cylinder cycles the other one back and forth. It has opposing check valves, so as to turn the motion into pumping action.

But does it say it loves to be run dry? I'm seeing that as a dead horse and have moved on to a dual system incorporating a Gast DAA-P501-GB 1/2 horse diaphragm pump as the first stage. I'll provide feedback once I receive and try them.

The Eaton is about the cheapest package I've found for the compressor, refrigerative drier, and reciever that is single phase and suitable for home use.

Here are some three phase ones, including the Quincy, which is top notch:https://www.northerntool.com/shop/too..._ven=bing_PPC&

Why not just use a coil after collection pot to chill vapor to a liquid/vapor state before entering the recovery pump or/and maybe add a buffer tank to before pump also in freezer with liquid line going to pump that should at least stop running dry all time and to run a little cooler as well?
Thanks for all you input and designs in this research between SPR and ICMAG folks great info.

coil chilled in freezer or D.I.

Maybe they don't want to tell anybody they are working on something.

Icog may be better to request inf on CARE 40 (R290) which is propane or r600a both used as refrigerants
