Arizona vortex tube technology will change the way you look at compressed air. Our vortex tubes can produce cold air using small amounts of compressed air. On average, customers can expect at least a 70° F/21°C drop from the ambient air temperature. Vortex tubes can be used to cool workers, machines, and electrical enclosures without the use of electricity or Freon. We have "packaged" our Vortex Tubes into spot cooling tools. Our spot cooling tool or Cool Tool allows you to aim the cold air exactly where it is needed. The Cool Tool is ideal for drilling, routers, and cnc machining because you are not using messy coolants, just clean dry air.
