Vortex Tubes are a low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. Using compressed air, they can produce temperatures from -50° to +260°F (-46° to +127°C) with flow rates from 1 to 150 SCFM.

These revolutionary micro-controllers allow for steady, repeatable downstream pressure as demand or processes change. The result, a precise, linear pressure control within a closed-loop system with ultra-high resolution (≤5 mV) and repeatability. 

Packed tower scrubbers, venturis, crossflows, wet dust collectors to control stack emissions from every industrial source. 65+ years experience solving issues with gases, odors, fumes and particulate, including combustible dusts. Extensive credentials in systems for food, chemical, pharma, metalworking and more. Systems engineered and manufactured in the USA. Expert free consultations.
