Fenik Yuma 60 L
Fenik’s Yuma 60 L is a portable cooling system that refrigerates perishable foods without using electricity.
Fenik’s Yuma 60 L Cooler is a portable system that refrigerates perishable foods such as fruits, vegetables, and dairy products. The cooler does not require electricity to operate and instead uses patent-pending PhaseTek™ membrane technology to facilitate evaporative cooling. The degree to which the device cools food depends on the ambient air temperature and relative humidity and may cool the internal storage space by 20-30 °F. Fenik, which is based in Somerville, Massachusetts manufactures the Yuma 60 L Cooler. The product was designed by Quang Truong, Jeremy Fryer-Biggs, and Spencer Taylor.
Fenik conducted R&D and field trials in Morocco with help from USAID. The product is currently available to purchase online.
Primary competitors include Zeer Pot, Charcoal Cooler, and there are other traditional Evaporative Cooling Chambers available in the market.
Target users currently include campers and individual consumers, but the company hopes to reduce the price to make the product accessible to emerging markets.

Fenik’s Yuma 60 L Cooler is a collapsible cooler that uses evaporative cooling. The dimensions when expanded are 57 x 45 x 39.5 cm and when collapsed are 57 x 45 x 11.6 cm. The weight when empty is 2 kg. The cooler can hold 60 L worth of food and 3.8 L of water in the internal reservoir. The cooling capacity depends on ambient air temperature and relative humidity. The cooler is made of food-safe plastic and PhaseTek™ membrane technology. The cooler has an internal chamber to hold food and a water reservoir between the chamber and outside wall. The reservoir is filled with water and as the water evaporates through the external walls, the internal chamber is cooled.

Designer specified performance targets include lightweight and fully portable. The designer provides a graph that shows the expected internal temperature in degrees Celsius given ambient air temperature and relative humidity.
Testing performed by Fenik determined to cool the internal storage space by 20-30 °F from ambient conditions. No third-party testing has been completed. Interview with representative
No third-party testing, the designer conducted field testing with support from USAID, National Geographic, and The Siemens-Stiftung Foundation.
No known safety hazards are related to this product.
The product requires a water supply and the manufacturer recommends using potable, soft water, although hard water can also be used if no soft water is available.
