Re: Hilsch Vortex Tubes...20kW cooling capacity
These tubes use inertia to spin the air and separate the hot and cold molecules, you blow into it and get like 900 degrees out one side and -50 out the other.
There is no such thing as a free lunch, same here.
Lots of the air in goes out, and it requires high pressure air, been there and done that. If you want cooling, vent compressed air ( its dry ) and get the abedetic cooling, this is how they make liquid air, nitrogen, etc.......
Sorry to be a downer again, have visited all these area, oh prices listed - how many do you want.
