Any further information on drying and reusing filter-dryer?

Sort of. Pulling a vacuum on the filter/drier and heating it with a torch certainly drives off water and contaminants. The vacuum pump oil reeks of mercaptan.
I pull the vacuum down to about 100 microns, and heating the filter drives it up to around 750. I then repeat this procedure until further heating stops the vacuum rising that far. The drier certainly removes mercaptan and water from the Propane and vac/heat removes them from the drier, however I can't really quantify how much. Now I think about it I suppose I could weigh the drier before/after.
I have a small low temperature compressor/condenser unit arriving today that is rated to 200W @ -40C, so I should be able to build a bottle cooler to experiment with water separation.
I also got in contact with Danfoss about their HC range of sight glasses, however have had no luck in obtaining some yet. Nobody seems to stock them anywhere.
