Evaptainers products are powered by PhaseTek™ , a patented pending membrane technology, that enables and enhances the effects evaporative cooling. Using this ground breaking technology Evaptainers can create a cooling effect of 10-15 Celsius from ambient conditions using no electricity at all.

PhaseTek™ is built into a bladder structure allowing the system to hold and transport water to the evaporative surface where the cooling effect is generated through the latent heat of vaporization.
