Reimagining Data Center Thermal Management
Let’s finally make heat work for us.
The computing boom is heating up—literally. From hyperscale data centers to modular AI clusters, every leap in compute power brings with it the same quiet cost: heat. A lot of it. And while processors evolve at breakneck speed, the systems designed to keep them cool have largely stayed the same. Fans. Cooling towers. Exotic fluids. And despite all that, the industry’s average PUE has been stuck near 1.5 for over a decade.
Separation Anxiety
Cooling and compute have become inseparable. They are a heroic odd couple — only cooling gets none of the glory and eats half the budget. Nearly 40–50% of a data center’s energy draw is spent just moving heat away from chips and out of the building. The tools used to do this—largely drawn from HVAC or industrial chemical systems—are retrofits, not solutions. And they’re reaching their limits.
Meanwhile, other high-heat industries have found ways to turn thermal losses into productive assets. In petrochemical and manufacturing, for example, heat reuse is foundational. The problem? Those industries rely on high-temperature systems—steam, pressure, boiling points. Data centers run cooler. Not cool enough to ignore, but just low enough to make most conventional heat recovery systems impractical. A frustrating thermal no-man’s-land.
New Ideas Needed
Power utilization efficiency has been flat for a decade.
Captis is changing that.
We build systems that turn waste heat into usable electrical power—directly from the rack. Our modules are compact, cost-effective, and designed for flexible deployment across different data center configurations. And they do something no other cooling solution does: they generate value while reducing cooling load.
Our long-term goal is radical—eliminate the need for external cooling towers altogether. But we’re starting with a more immediate mission: prove that low-grade heat in data centers doesn’t have to be wasted.
Pilot With Us
We're seeking data center operators ready to lead the next wave of innovation in thermal management. If you oversee energy efficiency, facility optimization, or thermal strategy—and are looking for a step-change improvement rather than another marginal gain—we want to hear from you.
Let’s test our systems in your environment. Let’s validate the economics and performance together. And let’s rewrite what it means to "manage heat."
