Cooling hardware built around Bitcoin mining is becoming part of the physical supply chain for AI data centers. AirJoule Technologies has acquired BitSink, a U.S. manufacturer whose cooling, electrical distribution and modular infrastructure has already supported more than 220 MW of high-density compute deployments across North America.

The transaction closed September 10 and was announced September 14. The company paid $18 million in cash and $9 million in stock up front, with as much as $40 million more in stock tied to future revenue milestones. A federal filing independently records AirJoule’s purchase of the South Carolina manufacturer.

Mining Infrastructure Is the Starting Point

BitSink made its name supplying infrastructure for cryptocurrency mining and now describes an integrated portfolio spanning liquid cooling, dry coolers, switchgear, power distribution and modular data-center systems. AirJoule says that installed base gives the combined company a direct path into the conversion of high-density mining sites toward AI and HPC workloads.

The hardware is substantial. BitSink lists dry coolers from 60 kW to 2.16 MW of heat rejection, coolant-distribution and direct-to-chip systems intended for sustained 100+ kW rack densities, and UL-listed switchboards and PDUs. Its modular catalog still includes a 1 MW, 40-foot immersion-mining container with an approximately 1.1 MW roof-mounted dry cooler.

Hydro ASICs Show Why the Plant Matters

The newest hydro miners make the infrastructure requirement obvious. A WhatsMiner M79S can put roughly 20 kW into a single chassis and cannot operate without a purpose-built coolant loop and industrial three-phase power. That moves cooling from an accessory to part of the machine’s operating system at the facility level.

BitcoinVersus.tech has recently examined the same trend from several directions. Hydro-cooled ASICs are pushing hundreds of terahashes from individual machines, while Canaan is installing mining heat-recovery infrastructure in Manitoba. At the site level, air, hydro and immersion cooling impose very different plant requirements.

From ASIC Heat to GPU Heat

The reason mining infrastructure transfers to AI is not that an ASIC rack and a GPU rack are identical. They are not. The transferable assets are the engineering disciplines around high-density power and heat: switchgear, PDUs, pumps, manifolds, heat exchangers, dry coolers, controls, service procedures and modular construction.

BitSink’s current liquid-cooling roadmap reflects that shift. Its systems include facility-scale coolant distribution, rack-level direct-to-chip manifolds, rear-door heat exchangers and redundant pump skids. AirJoule is adding another element: atmospheric water generation designed to use low-grade waste heat to produce distilled water from air.

That combination could matter where data-center growth collides with water constraints. Closed-loop liquid systems still need heat rejection, maintenance and make-up strategies, while high-density AI campuses increasingly face scrutiny over both electricity and water. AirJoule argues that waste heat from BitSink cooling loops could become an input for its water-generation equipment.

South Carolina Adds a Manufacturing Layer

BitSink also brings domestic manufacturing. AirJoule says the business is expanding into a 65,000-square-foot facility in Chesnee, South Carolina. That matters because the bottleneck in a high-density data center is not only GPUs or ASICs. Switchgear, distribution equipment, cooling hardware and commissioning capacity can determine when energized megawatts become usable compute.

The acquisition therefore captures a broader change in Bitcoin mining infrastructure. Equipment originally optimized to keep ASICs powered and cool is becoming valuable beyond SHA-256. The physical plant around the miner—electrical distribution, coolant loops, heat rejection and modular deployment—may outlive several generations of compute hardware.
