Anyone running a CM-EP yet? EcoGreen is selling them now.
It means a filter to scrub the butane between the pump and the tank, to remove any oil contamination."Additional scrubbing". Is this a process you've covered in your blog somewhere?

If you look at the issue holistically, water contamination is also an issue, so WolfWurx now runs the pump discharge through a heat exchanger, followed by a water trap, and then a filter drier, before returning it to the tank for recycle.
The purpose of the heat exchanger is to remove the heat, so as to return the vapor to a liquid, but that also lowers the temperature of the butane to waters dew point.Is the purpose of the heat exchanger to condense water vapor prior to the water trap and filter/drier?
I think the apions are oilless And are made to handle liquid more so than other recovery machines which are made to pump gas!I absolutely have pulled oil off the pistons every time I filled cans or try to distill with a appion.
So, while the Sporlan specs don't indicate R600 compatibility, there aren't any materials in the filter that will dissolve in the presence of R600, either. Alrighty then.
I'm a little unclear about the state of the butane on the output side of the pump, though. If the output side is under pressure, won't the butane tend to heat and liquify when it's compressed? Kinda like a refrigeration system? Come to think of it, isn't a closed system a basic fridge of sorts? A "reefer" so to speak? ;-)
