Aussie Flexi Cool Vest

The Aussie Flexi Cool Vest has a series of cooling elements that are designed to cool the operator working in 60°C for up to 90 min. In more extreme conditions, the period of operational use decreases proportionally. 4 h is easily attained at temperatures of 45°C in normal firefighting or industrial applications.

The vest is normally worn over a T-shirt, wrapped tight against the body and under covering garments, ie, overalls, protective clothing or uniforms.

The vest uses Temptech elements which consist of a non-toxic, non-flammable blend of salts sealed in an aluminium wrapper. The salt compound melts at 28°C. At the moment of transition from solid to liquid, 50 times more energy is absorbed compared to a rise of 1°C when the compound is already in either liquid or solid condition. The vest is therefore able to absorb the excessive body heat.

The elements recharge, ie, reform salt crystals, at normal room temperature (20°C) in about 4 h. If the elements are placed in a freezer they recharge in less than 10 min. They can be used and recharged over and over again for up to 1000 cycles.

The vest is fully adjustable so that one size fits all. It is designed to be easy to put on and closes with velcro on the shoulders and sides. It incorporates 16 Temptech elements to absorb heat. Apart from the standard material, it’s also available in fire-resistant Nomex material. The vest can be washed in a warm water cycle with the elements removed and weighs only 1.6 kg.

Temptech elements can be easily replaced and most users keep one or two spare sets of elements available for prolonged application.
