Vortex tubes from NOVACOM allow the transformation of compressed air into two different air flows: heated air and cooled air. Cold stream guns and Vortex tubes from NOVACOM are advantageous in various ways: maintenance-free, explosion proof, pneumatic, no moving parts. They permit a clean work area and are very well adapted to a use in a factory or the laboratory. Rack air-coolers from NOVACOM keep cool the inner life of switch boxes and control enclosures by supplying them with cool air and evacuating hot air. They also protect them from dust and humidity. In this way, they prevent break-downs, damage and machine failures, which could be caused by overheating of parts.
