Fenik are electricity-free mobile refrigeration units which run at low-cost. Utilizing the phenomenon of evaporative cooling, food is stored in a double-walled container where water evaporates through the porous outer wall, thereby cooling down the inner container. Compared to the rather more energy-intensive vapor compression refrigeration, they are ideal for use in off-grid rural areas with low relative humidity.
