Vortex Tube operated cabinet enclosure coolers such as the Nex Flow Frigix-X Panel Coolers operate utilizing compressed air wherein one end gets hot, and the other end gets cold. They find applications in particularly dirty environments and hot and wet factory climates.
Because of the rough environments they are subjected to, construction materials are pretty necessary. Some manufacturers utilize stainless steel with the vortex tube (cold temperature generating portion) and then packaged it in an aluminum housing and assembly, usually not anodized. So after a short time, the appearance of the aluminum, especially if not anodized in such environments, look pretty deteriorated.
But it is mainly in hot and humid environments where the combination of stainless steel with aluminum can be a problem due to the possible effect of galvanic corrosion between these two very dissimilar metals. Due to this corrosion effect, I have personally seen a vortex-style cabinet enclosure cooler with a big gaping hole in its aluminum housing.
So if choosing vortex tube operated cabinet enclosure coolers, it is a good idea to check what they are made off. Nex Flow makes them from stainless steel. The vortex tube, housing, and attachments are stainless to avoid this corrosion issue. Stainless steel will obviously hold up much better than aluminum in a nasty factory environment.
Nex Flow manufacturers specialized compressed air products for blowoff, cooling, and moving c/w quality accessories for controlling, monitoring, and filtering compressed air.
