Factory-built power and cooling for the density of AI.

GW Modular builds pre-integrated cooling, power, and white-space modules for high-density data centers. Start with the HCS cooling unit that is already in production, then scale to the full module family, all the way to a complete HD3 modular data center.

Why now

AI racks broke room-level cooling. The fix has to be at the row, and on schedule.

High-density compute is outrunning legacy cooling and outrunning supply chains. GW Modular attacks both problems at once, with vertically integrated steel supply behind it.

🔥

Density is exploding

AI and HPC racks are pushing toward 100 kW. Room-level air handling cannot remove that heat where it is produced.

Schedule is the bottleneck

Equipment lead times and field-labor scarcity, not the IT gear, are what slip data center delivery dates.

This one is already built

The HCS is engineered and in production today, and DBM Global steel supply protects lead time and price.

HCS: cooling delivered at the source, in a serviceable module.

The HAC Cooling System (HCS) captures hot return air and supplies cooled air right at the high-density row. Factory-assembled and tested for repeatable, predictable deployment.

  • 195 kW nominal cooling per unit, dual-fan dual cooling-coil architecture with high-efficiency EC fans.
  • 480V single-source power with centralized controls and a per-unit mounted disconnect.
  • Independent serviceable fan modules, leak detection, and drain pan, redundancy-ready.
  • 1 to 12 units per 72 ft pod, scalable without a full system redesign.
  • UL listed, ETL certified, third-party performance tested, drops into the GW HAC/CAC white-space system.

Sell the part, or build the whole. The same shop does both.

Every module is factory-engineered, integrated, tested, and shipped ready to deploy. Buy a single cooling unit, a full white-space row, or the complete data center.
