Vortec Vortex tubes
Vortec’s Vortex Tubes convert compressed air to a low-pressure cold air source to keep electronic enclosures and panel components protected so they can operate precisely. A compressed air stream enters the vortex tube where it spins rapidly, splitting into hot and cold air streams. Most Vortec Enclosure Cooler models are thermostatically controlled to regulate cabinet temperatures within a specified range.
