Air-to-Water:
Creating fresh water where none exists.
Harvesting fresh water from airborne humidity.
Through our Air-to-Water application, we harvest water by combining atmospheric humidity, heat and air flow producing 5,000, 10,000 or 20,000 liters per unit, per day.

How Rainmaker’s Air-to-Water technology works.
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.
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 liters of drinking water per day.
Energy Agnostic
Rainmaker’s Air-to-Water units offer you the most flexibility for power options. Choose from solar, wind, grid, diesel or a combination with zero to small carbon footprint.

WATER-TO-WATER TECHNOLOGY
An ocean of opportunity to create fresh drinking water.
The world has plenty of seawater and polluted water. Up to now, the challenge has been to convert that water into drinking water at the point where it’s needed and at a scale that’s appropriate and affordable. The Rainwater Water-to- Water units have solved those problems.
