Zeolite Technology

Adsorption cooling:
Easy in principle.

FAHRENHEIT chillers operate on the principle of adsorption. Adsorption occurs when molecules of a liquid (in our case water) adhere to the surface of a solid (in our case zeolite crystals). This causes the liquid to evaporate, generating cold. Once the solid material is saturated, heating it will cause it to release the adsorbed liquid, allowing the process to start anew.


Reaching unprecedented performance through patented zeolite technology.

Zeolite crystalization process:
A breakthrough for cooling technology.

Zeolites are a class of non-toxic crystals which are ideally suited for adsorption. In order to optimally apply zeolite to our heat exchangers, we developed a process called PST – Partial Support Transformation. This process, via sophisticated chemistry, makes zeolite crystals grow directly out of the surface of the heat exchangers. This alleviates the need for any kind of coating or glue and optimizes heat conductivity. Because zeolite can reach even the smallest cavities of porous or fibrous material, the surface-to-volume ratio and therefore power density can be maximized.

In addition, the zeolite layer is a very effective protection against corrosion. Without adhesives or glue in between the crystal and the heat exchanger, heat conductivity is maximized.

This innovation in material science and design allows a significant reduction in size of the adsorption modules, for a given cooling power. Therefore weight, size, and cost can be improved simultaneously.
