Your Water Source In the Dry Zone

A Revolution in Atmospheric Water Generation Technology

The problem we solve

Clean water is scarce in dry areas, but desperately needed. Arid regions are expanding, dry seasons extending, contamination spreading.

Legacy AWGs miss the mark.

Traditional atmospheric water generators rely on direct cooling of humid air and require high humidity levels to function effectively. They simply cannot operate in dry areas, fail when humidity fluctuates in the dry season, and have intensive, costly energy requirements.

We’ve changed the paradigm.

Our breakthrough Cyclic Absorption technology makes clean water possible where legacy systems can’t and alternatives aren’t available. A proven brine solution and unique thermodynamic cycle change the physics of the challenge. Providing reliable water security all year round, anywhere.

How It Works

‍Extracting Water from Dry Air  
in 4 Simple Steps

The process of Cyclic Absorption AWG for extracting water from dry air in 4 simple steps. The process of Cyclic Absorption AWG for extracting water from dry air in 4 simple steps.
step 1

Absorb – Capturing Water from the Air

Fresh, filtered air is drawn into the system, where it meets our liquid desiccant. This material naturally attracts and binds water molecules — even in dry climates — saving  the high energy cost of cooling the whole air mass.

The water-rich desiccant then flows to the generator for extraction.
step 3

Produce - Efficiently Creating Pure Water

The water vapor is cooled and condensed into pure liquid water.

By avoiding the need to chill large volumes of air, our process uses up to 65% less energy than legacy AWG systems.
Desiccant - a substance that absorbs moisture from its surroundings. H2OLL's liquid desiccant is completely inert, and 10x more salty than seawater. It acts as a physical barrier and sterilizer keeping biological and chemical contaminants from entering the produced water.
step 2

Regenerate – Releasing and Recharging

Inside the generator, the desiccant enters a controlled vacuum environment, releasing its captured moisture as water vapor in a process called desorption. This creates a micro-climate with nearly 100% humidity.

The desiccant is instantly regenerated and ready to absorb again, enabling continuous cyclical operation.
step 4

Mineralize, Monitor & Serve – Healthy, Great-Tasting Water

The pure water passes through natural limestone, enriching it with calcium, stabilizing it and enhancing its taste.

As it is dispensed, a UV-LED treatment ensures the highest level of safety — delivering fresh, healthy water, instantly.
