Who are we?

WLT International AG is a highly innovative company, founded 2022 and headquartered in Basel, CH. WLT maintains two offices in Germany. The marketing office is located in Hamburg and the technical development center in Göppingen (both WLT Deutschland GmbH).

Our products are based on a Fraunhofer (FAG) development of an atmospheric water generation (AWG) in large quantities. WLT managed and financed the technological development, together with FAG. The product now is ready to market. WLT owns the worldwide technology licenses.

In 2018, the first milestone was set with the proof of concept of a pilot plant in the dry and dusty Atacama Desert in Chile.  The next milestone will be the product certification, which is planned for summer 23.  For the realization of commercial pilot plants, WLT partners with selected companies.

Technic

Currently, there are a wide variety of technologies for water generation. From the use of groundwater, to seawater desalination, to water generation from the air. We uns the AWG technology of liquid absorption.

The ambient air, sucked by a fan, is brought into contact with a hygroscopic salt solution. This binds part of the water from the air and heats it in the next step, desorption. Here, the highly purified water is separated from the salt for further use, which is recycled in concentrated form. The salt solution is practically a loss-free component of the absorption circuit.

The technical process allows water production down to a humidity of 10%. Certification of the WLT absorption unit as well as the overall product are scheduled for summer 2023. Quantities of 100 or even more than 1,000 liters per second (or 3,600 m³ per hour) are feasible.
