The Zeer Pot was designed as an alternative to electric refrigeration. This makes it ideal for areas that do not have access to the electric grid.
Evaporation cooling technology is the idea behind the Zeer Pot, which uses two earthenware pots and wet sand to evaporate moisture in order to maintain a lower temperature within the pot than in the surrounding environment. This allows for the preservation of produce in very hot climates.
One smaller pot is placed inside of a bigger pot with moistened sand resting between the two. Water is added to the sand twice a day, in order to continue the evaporation process.
The pots are then covered with a damp cloth, which allows for the water in the sand to evaporate towards the outer surface of the larger pot. This process reduces the temperature in the smaller pot by several degrees, depending on the outside temperature and humidity. The Zeer Pot can help keep produce fresh for up to 20 days.
The Zeer Pot is an open source technology solution. The design is available for free and can be locally manufactured using easily sourced materials.
