The World’s Lightest Untethered Active Cooling Garment

Did you know that prolonged exposure to or physical exertion in high temperatures can cause your body to overheat? If your job exposes you to extreme heat, your body temperature can rise to 40 C or higher. If this happens, you have a greater risk of experiencing heatstroke.

The Solution – CO2 cooling vest

To avoid heat exhaustion, one solution provided to workers expose to heat like cook, welders, construction workers, fire fighters, emergency responders, etc is a protective wear with active cooling system.

Among the best ones is the Porticool Personal Cooling System by Porticos. This active cooling garment that uses refillable liquid CO2 tanks takes advantage of both conductive and evaporative cooling based on the endothermic expansion of liquid CO2. While passing through miniature tubing in the vest, the liquid CO2 converts to gas and this is when conductive cooling happens. Evaporative cooling occurs when the gaseous CO2 gets redirected throughout the vest and expelled through porous tubing. This then helps evaporate the body’s perspiration and aids the body’s own ability to cool itself.

Weighing for only 1.8 lbs in total weight, Porticool II is considered to be “the world's lightest untethered active cooling garment.” It is also the only active cooling system safe to use in explosive environments. This active cooling garment can be worn inside of a fire thus protecting firemen from heat stress.
