Karman Industries Closes $20M Series A to Scale Data‑Center Cooling

Why It Matters

The technology could dramatically cut data‑center power usage and real‑estate costs while turning waste heat into a usable asset, addressing both sustainability and capacity pressures in the hyperscale market.

Key Takeaways

• Karman closed $20M Series A to fund HPU production.
• HPU uses CO₂ chillers, eliminating water and reducing footprint 80%.
• Kompressor spins at 30,000 rpm, promising 25% efficiency gain.
• Gigawerx targets 1 GW cooling capacity by 2027, scaling to 4 GW.

Pulse Analysis

Data‑center operators now consume roughly half of global thermal‑management energy, and rising rack densities are pushing traditional air‑ and liquid‑cooling systems to their limits. Karman Industries leverages aerospace‑grade engineering to rethink this challenge, positioning waste heat as a resource rather than a liability. By integrating CO₂‑based chillers, the company sidesteps environmentally harmful F‑gases and captures residual energy to drive a turbine, a design that aligns with growing ESG mandates and the push for carbon‑neutral operations.

At the heart of Karman’s offering is the Heat Processing Unit, a modular suite that can be tailored to a facility’s specific thermal profile. The proprietary Kompressor, rotating at 30,000 rpm, delivers rapid heat extraction while occupying a fraction of the space required by conventional chillers. Early tests indicate up to a 25% improvement in power‑usage effectiveness (PUE) under extreme conditions, and the system’s water‑free design eliminates recirculation losses, enabling tighter temperature control and lower operational overhead.

The $20 million funding round, led by Riot Ventures, fuels the ramp‑up of Karman’s Gigawerx plant, which aims to ship 1 GW of cooling capacity by late 2027 and eventually expand to 4 GW. As hyperscalers grapple with soaring capex for cooling infrastructure, Karman’s compact, efficient solution offers a compelling alternative that could reshape procurement strategies and open new revenue streams through heat‑to‑energy conversion. If the company delivers on its promises, it may set a new benchmark for sustainable, high‑density data‑center design.

Deal Summary

Los Angeles‑based Karman Industries announced the closing of a $20 million Series A round led by Riot Ventures. The funding will be used to scale production at its Gigawerx factory and accelerate deployment of its data‑center cooling technology. The round highlights investor interest in sustainable thermal management solutions.
