The Dräger CVP 5220 comfort vest helps to absorb excess body heat and offers comfort for the wearer when working in hightemperature surroundings or performing tasks that are physical enough to cause sweating.
Protective Clothing - Dräger CVP 5220 Comfort Vest can simply be worn underneath protective clothing such as the TeamMaster pro-ET chemical protective suit.
Its cooling action is derived from 22 PCMelements (Phase Change Material) integrated into the cooling vest, whose primary content is sodium sulphate decahydrate.
At temperatures below 22°C, the content of the PCM-elements is in a solid state. At a surface temperature of 28°C, the content of the PCM-elements becomes liquid through absorption of heat energy.
At higher ambient temperatures, the raised body temperature of the comfort vest wearer can be reduced by approx. 3-4°C.
Depending on the level of physical work and the ambient temperature, the cooling benefit for the wearer of the vest can last for up to 3 hours.
An ambient temperature of lower than 22°C provokes a phase change and the contents of the PCM elements become solid again within approx. 0.5-2 hours.
