The binding constraint on AI at scale isn't the chips, it's keeping the chips cool with less water and energy
HaloDrive™ Modular Cooling System (MCS) is a patented power-agnostic, DC-native architecture that makes third-party CDUs more versatile and adaptable. Plug in on AC today, switch to DC when the facility is ready — no change to the CDU.

Conventional CDUs hide power loss in cooling — HaloDrive MCS reclaims that power for compute
Conventional AC CDUs use VFD-driven pumps that quietly consume 3–5% of facility power— losses buried in the system and missed in audits. HaloDrive™ MCS eliminates the VFD with native DC operation, delivering 0% motor conversion loss on AC or 800V DC. At 100 MW, that reclaimed power can run 2–4 additional GB200 racks without increasing the power budget.
Dramatically less upstream electrical infrastructure Wire gauge can drop to deliver a 57–82% like-for-like copper reduction vs. conventional AC 480V 3-phase. Smaller panels, fewer breaker slots, lighter switchgear. With no need for VFDs, facility electrical design can be sized for steady-state loads only saving vast amounts of time on construction.
Power-agnostic — no site prerequisite Accepts 3-phase 340–528VAC or 500–850VDC natively. Plug in on AC today, switch to DC when the facility is ready with no change to the CDU. No AC→DC rectifier required. No stranded cooling assets as facilities migrate.
Optimized ΔT reduces pump energy per MW Magnetic drive hydraulics enable 15–20°F ΔT vs. 10–15°F for conventional induction pump systems, more heat rejection per gallon, lower pump kW per MW of cooling delivered.
Configurable CDU architecture is more versatile No matter the configuration, AC or DC, the MCS efficiency improvement speeds construction and, once operational, precious energy otherwise wasted by infrastructure is reallocated to IT where it matters most.
