Transform waste heat of AI racks from a cooling liability into a cooling asset for the 100+ GW of AI data centers globally
At Vulcadi, we focus on providing the most efficient and most economical solutions to reuse the 40°C to 50°C waste heat generated by AI compute workloads, which will lower peak power usage, eliminate water consumption and increase sustainability of AI data centers globally.
The AI infrastructure boom has created a critical thermal paradox: high-density GPU clusters consume hundreds of GWs of electricity and discharge all the energy as massive volumes of waste heat at 45°C, a temperature typically considered "stranded" and vented via energy-intensive dry coolers. Our proprietary Ultra-Low-Lift Absorption Chiller is the first in the market that can transform this liability into a strategic asset. By capturing 45°C heat in return water, our system generates stable 18°C chilled water. This creates a "Circular AI Cooling" loop where the thermal byproduct of compute drives the facility's secondary cooling infrastructure that is needed to cool down storage and memory devices, networking racks, electrical equipment, etc.
The economic impact is two-fold. First, it slashes power OPEX by eliminating the mechanical refrigeration load. Second, Vulcadi’s technology shaves DC summer peak power usage, allowing DC operators to allocate more grid power to revenue generating IT workload throughout the year. In a market where grid capacity is the primary constraint to AI growth, this means more incremental revenue.
Our technology can easily scale up from 30kW of cooling capacity to 1MW of cooling capacity per unit. Our prototype product has gone through rigorous testing on the factory floor and has shown it can run reliably with 45°C driving heat to generate 18°C chilled water. If you are interested to partner with us to do a proof-of-concept run at your facility, please reach out to info@vulcadi.com

Compared to existing absorption chillers on the market, the innovations of our patented technologies are centered around the designs and controls of multi-stage, multi-level, variable effect, which enables the usage of 40°C-45°C waste heat and running reliably at any environmental conditions. We have published peer reviewed journals for the thermodynamic science behind our technology, feel free to reach us at info@vulcadi.com for the links
Vulcadi's absorption chillers can be driven by 45°C waste heat from either the secondary loop (IT liquid loop) or the primary loop (facility water loop). Connecting to the secondary loop is preferred as the temperature tends to be higher and our absorption chillers only uses approved wetted materials that don't contaminate the PG25 heat transfer fluid. We have architect designs for both use cases, please reach out at info@vulcadi.com for further discussions.
