Data centres
Cooling that powers your data centre.
Brownian turns the heat from your liquid-cooled racks into electricity, and replaces the dry coolers you would otherwise buy and run.
Every watt a data centre uses ends up as heat, and today you pay again to get rid of it. Brownian is developing a heat-to-power cooling system for direct-liquid-cooled data centres. It takes over heat rejection from the warm-water loop and converts part of that heat into electricity on site. Your cooling stops being a cost centre and starts giving energy back.
Cooling without the overhead.
One system rejects your chip heat and makes power while it does it.
Built for warm-water liquid cooling.
The direction the industry is already moving.
No evaporated water.
Fewer machines to buy, run, and maintain.
