Workers in extreme temperatures wear Vortec Cooling Vests (VCVs) to minimize heat stress and fatigue.  The VCV's improve comfort and productivity. 

Vortec personal cooling vests have two components:

• a cooling tube that generates cold air to provide air flow to the worker
• a diffuse cooling vest through which the cold air flows to cool the worker’s torso

VCVs are available in two cooling capacities; 1500 BTUH and 2500 BTUH.   All models can achieve temperature differentials of +/- 45 – 60 deg F from the inlet compressed air temperature using vortex tube technology. These models are adjustable by the worker using an integral temperature adjustment knob.

The diffuse air vests are available in three sizes; large, xlarge, and xxlarge which provides continuous cooled air through its perforated inner lining. The durable vest allows a full range of motion with no airflow restrictions, and does not absorb sweat or other contaminants. Body cooling vests can also be worn under other protective clothing.
