Workers in extreme temperatures wear Vortec Cooling Vests (VCVs) to stay cool by minimizing 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 airflow to the worker
• a perforated cooling vest through which the cold air flows to lower the worker’s body temperature

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 perforated air vests are available in three sizes: Large, X-Large, and XX-Large which supplies cooled air continuously 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.

*Note: NIOSH approves only complete Supplied Air Respirators (SAR) Systems. None of the Vortec Cooling Vest products listed above are approved for use with a respirator system. More can be found about the requirements in CFR 84.131.
