‘Kumulus-1’ a startup in Tunisia has developed a portable Atmospheric Water Generator (AWG)

Kumulus is a water tech start up with mission to provide drinking water in an economical and sustainable way. It has build small portable machine that create drinking water from air!

This machine can fit in a 1m3 cube and can be equipped with a solar power pack, making it fully autonomous and independent. The Kumulus-1 is a smart machine, offering options of mobile control through our dashboard and app, as well as functionalities that ensure water is delivered in a sustainable and economical way.

Kumulus-1 machine, which they call an Atmospheric Water Generator, can produce between 20 and 30 litres of drinking water per day.

Water-from-air harvesting includes any method used to extract water from the air/atmosphere.

It includes both active and passive forms of extracting water from the air.

Kumulus has been deployed in many locations globally and especially in schools where there is a shortage of drinking water.

The unit would work to draw water out of the environment at a rate of up to 30-liters per day before filtering it, mineralizing it and storing it for consumption.

An Atmospheric Water Generator (AWG) is a specific type unit/device that uses a power source (solar or other) to actively extract water from the (humid ambient) air.

They can use different extraction methods such as cooling rods/coils (cooling condensation), or desiccants (wet desiccation using solutions and substances).

For cooling condensation units – ‘as a rule of thumb, cooling condensation atmospheric water generators do not work efficiently when the temperature falls below 18.3°C (65°F) or the relative humidity drops below 30%’
