- My Weekend Hilsch Tube Project
You must be logged in to reply.
I made a Hilsch tube in my shop this weekend. It's quite impressive! With just a little experimentation, at 80 PSI. the temperature is 17 Degrees on one end and about 70 degrees on the hot side. The pipes are 1/2" PVC. The center hole where the vortex is formed is 11/32" with a 1/4" hole in the washer on the cold side. There are 4 equally spaced Drill #53 (.059) holes Tangent to the center hole that forms the vortex. The valve on the hot side is from a old air tool. It's quite loud and you can hear the air "spinning up" like a turbo! It uses lots of air. Pictures sent to Phillip Torrone.Posted by earla on March 04, 2007 at 13:18:54 Pacific Time
