We Turn Waste Heat
Into Clean Water.

Cooling water for AI data centers, produced on-site from the heat they already throw away. 5× cheaper than grid water.

AI demand doubles global data-center water use

"Currently, we have a community backlash issue on the amount of water that we use."

The Technology

Our Sorbent Turns Waste Heat Into Cooling Water.

01
Capture
The sorbent pulls water vapor from ambient air, from 35% relative humidity.
02
Regenerate
Waste heat from 45 °C releases the vapor.
03
Condense
The vapor condenses into liquid water.
04
Cool
The water feeds the site's cooling system, with no freshwater withdrawal.

“Like a sponge, but you heat it instead of squeezing it.”

Plugs into existing heat-recovery loops. Electricity only for fans and pumps.

Impact

€800k Saved Every Year per 40 MW Data Center.

€1.1/m³
