It is possible to harvest water from air almost anywhere in the world. Our core Air-to-Water unit uses a turbine that forces air through a heat exchanger, where the air is cooled and condensation takes place. A hybrid solution (solar/ wind/grid) can be deployed to the same effect by driving a ventilation system. 

 

HOW IT WORKS?

​

Lowering the temperature of air requires minimal energy. When the temperature falls below its dew point, water 

droplets will form. These droplets then collect in a water storage compartment. 

The water production of the Air-to-Water system depends on the environment. The actual amount of water that can be produced in a particular location will depend on the average wind speed, the ambient temperature, and the relative humidity. 

 

To make the system work under different conditions, the turbine can be adapted to the environment in which it will be used, such as adjusting the blade diameter and the height of the tower to maximize the efficiency of the unit. 

The turbine can also be combined with solar and/or traditional power to maximize water production. 

 

In each case, Rainmaker engineers will optimize a solution for every customer. Our Air-to-Water units use renewable energy and are 

available in three sizes, producing 5,000, 10,000 or 20,000 litres of drinking water per day.
