The PCM elements start absorbing and storing excess heat at a temperature of 28°C (82°F). Heat absorption from the body or from an external source continues up to 4 hours until the elements have soften.
The PCM elements recharge automatically in approximately 2 hours at room temperature (20°C / 68°F). The process requires less time in lower temperatures.
The PCM elements consist of a non-toxic, non-flammable blend of salts. The elements can be repeatedly used and recharged without removing them from the vest.
spare and replacement elements
To facilitate prolonged periods of work, spare sets of PCM elements are available for rotation.
