oh i seeeee
that sounds a really good idea, dont tell james he may steal that one 
any testing on this method?
wouldnt it be too fast a flow?
although isnt the idea to keep liquid hot instead of chilling it rapidly?
hmmmmm, need to get my head round that one , off to sit in corner for an hour...
RM ... most of the info is in this thread ...
http://www.biopowered.co.uk/forum/index.php/topic,295.msg2612.html#newYes, very defiantly it CAN be too bigger flow. That's something that needs great care if the idea is used. From my tests to date it works, but I'd only recommend it for dewatering oil and Bio.
Re keeping it hot ... yes and no ... the idea is to get the water out as quick as possible, even if it cools the oil, but from tests to date, a 3Kw immersion can keep up with the cooling effect of my compressor at full tilt and still raise the temperature slowly. To recover a bit of heat, you can run the venturi simultaneously, which will circulate some of the vapour through the SHHE, if you have one.
I have considered repositioning the SHHE to recover heat from the full flow of the compressor, but that's another toit.
