About the Company

ThermalWorks

Waterless cooling technology for high-density AI data centers

ThermalWorks operates as a data center cooling technology company, engineering waterless thermal systems for high-density AI computing loads. Its main products include hot aisle containment, skid-mounted multi-function chillers, and modular liquid and air cooling units supporting hybrid or all-liquid setups at high rack densities. It also provides design, deployment, and operations services, using digital twin modeling, a modular supply chain, and real-time monitoring. What sets ThermalWorks apart is its zero-water design paired with waste heat recovery technology that repurposes IT waste heat into usable heat, while keeping power usage effectiveness low. The goal is to help operators meet AI-scale computing demands sustainably, without the water-use tradeoffs of legacy cooling systems.
