Evaptainer EV-8 is a light weight, easy-to-carry, fully portable refrigeration unit that can keep perishables like fruits, vegetables and dairy products fresh in the hot summer months. It requires no electricity to operate and is 100% eco-friendly with no greenhouse gas emissions. Some prototypes of the product have been tested, but the EV-8 is not yet available in the market.
The usage of Evaptainers could be extended in natural disaster situations. In addition to food storage, in post-disaster settings the vessels might also be used to store medical supplies at cooler temperatures without the use of electricity that will most likely be disrupted under such circumstances.

N/A evaporative cooling uses water
The EV-8 uses PhaseTek technology, that enables and enhances the effects evaporative cooling. Using this technology Evaptainers can create a cooling effect of 15-20 Celsius from ambient conditions using no electricity. The membrane technology becomes activated when a user fills the internal reservoir with any source of water (e.g. tap, well, river, lake). The walls of the device then begin to draw out heat from the interior of the device through evaporative cooling.
Tech support can be requested via e-mail, available in the US and Morocco. Interview with representative
Some components are available upon request. Interview with representative
It has a 1 year full warranty and 3 years limited warranty. So far the first prototypes tested have lasted 2.5 years without problems. Interview with representative
Manufacturer Specified Performance Parameters
Vetted Performance Status
According to manufacturer's field testing the EV-8 is 5% more thermally efficient than a Zeer Pot. The impact on users is said to be a 10% of income savings, due to the time users can work instead of going to the market. Interview with representative
No safety precautions specified.
