Dual-Action Personal Air Conditioners

Working in extreme environments can take a toll on workers, but dual-action Personal Air Conditioners (PACs) from Vortec keep workers comfortable and productive in either hot or cold working conditions. PACs minimize heat stress and fatigue in elevated temperatures, or with simple adjustment, they raise vest and body temperatures to ward off the cold. 

A dual action PAC generates cold or hot air to provide air flow to the worker, along with a cooling/heating vest which diffuses the air flows around the worker’s torso. Durable, plasticized vests are available in three sizes and provide continuous cooled or warmed air through its perforated lining. They do not restrict movement, do not absorb sweat or other contaminants, and can be worn under other protective clothing. Vortec PACs are ideal for any work environment where temperature extremes pose a problem, including foundries, steel mills, boiler rooms, mines, smelters, glass manufacturing, cold storage and powder painting lines.

Cold-only PACs feature an integral temperature adjustment knob which allows workers to easily “dial in” the desired temperature. When wearing PACs, workers require fewer and shorter cooling and warming work breaks, increasing overall productivity. 

Vortex Tubes convert compressed air to a low-pressure cold or warm air source. A compressed air stream enters the vortex tube where it spins rapidly, splitting into hot and cold air streams.

  • cold working

    cold working

    Deforming metal plastically under conditions of temperature and strain rate that induce strain hardening. Working below the recrystallization temperature, which is usually, but not necessarily, above room temperature.

  • fatigue


    Phenomenon leading to fracture under repeated or fluctuating stresses having a maximum value less than the tensile strength of the material. Fatigue fractures are progressive, beginning as minute cracks that grow under the action of the fluctuating stress.
