EXAIR Super Air Amplifiers used in Thermal Spray Cooling Application

Every once in a while, we will run across a video where EXAIR products are being used. I just ran across one on YouTube the other day and thought it worth mentioning here. The video is produced by Air Products Company. The video is intended to promote their patented cryogenic cooling system. The purpose of their system is to minimize heat transfer into the work piece as much as possible by providing a very cold stream of gas immediately after the plasma spray has gone over a section of the work piece.

What I found interesting is that EXAIR 2” Super Air Amplifiers are also being used within the application to provide either the primary or secondary cooling (however you may want to look at it). Air Amplifiers have the ability to provide a great deal of cooling power when there is a temperature differential between the target and ambient air surrounding the application. You cannot get much hotter than plasma, and so the cooling benefits can be realized.  A Super Air Amplifier will draw in surrounding air and propel it toward the target to get as much volume of air moving over the work piece as possible.

There is no doubt that the Air Products cryogenic cooling system does a good job. I would simply like to point out that the “compressed air cooling” mentioned in the video is provided by EXAIR. If a picture is worth a thousand words a video is worth a thousand pictures.
