Hello Krups
Same type of idea as a vortex tube as used on jet engines and miners cooling suit ,hot and cold produced from compressed air I was well impressed when I first saw one in use in research department

hi dave,

vortex tube is an old thing and works on a totaly different princip, yet its widly used especialy on milling machines for cooling the drill bits.

very expensive to run.

I once bought a small Vortex tube for testing but you need a damn big compressor before it works fine.
There were some different ofifices in it.

first time iv come across all these other methods of cooling, and its pretty amazing...any others out there ?
do u guys reckon this is the future ? to create a method of cooling withough using refrigerant ? or is it a race ....either that...or until someone comes up with a refrigerant thats totally safe to use...

i first saw this website about 6 years ago..

slowly they are progressing to their holy grail -which, if they are right, means widescale redundancy for fridgies..
