AI demand is exploding. Power is the bottleneck.
AI demand is exploding, but electrical capacity isn't keeping pace. Power availability, not GPU supply, now caps AI buildouts. Every megawatt reserved for cooling is a megawatt that can't run GPUs. Cool-E combines permanent magnet motors with advanced control logic to cut cooling power draw, returning existing megawatts to revenue generating compute.
Cool-E 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, with no change to the CDU.
Cool-E turns cooling into compute.
Each recovered megawatt is worth an estimated $10M to $27M per year to a data center operator.

Capacity Tiers — maximum continuous amperage (MCA) vs. industry baseline
By cutting MCA roughly 60% at the plant level, Cool‑E MCS enables much smaller conductors, panels, and switchgear than a 480 V AC, VFD‑heavy baseline. Wire gauge can step down for a like‑for‑like copper reduction approaching 80% in line runs, with correspondingly lower I²R losses and thermal loading. With no VFDs and no climate‑driven amp escalation, electrical design can be sized for steady‑state current only, simplifying coordination and compressing construction timelines.

Conventional CDUs hide power loss in cooling, Cool-E reclaims that power for compute
Power availability now limits AI growth more than GPU supply. Cool-E recaptures megawatts lost to motor amps without cutting cooling capacity. Conventional AC CDUs rely on VFD‑driven induction pumps that quietly burn 3–5% of facility power, with losses dispersed across the plant and often invisible in audits. Cool‑E replaces that stack with native DC HaloDrive™ motors, eliminating VFD conversion loss and collapsing drive inefficiency into a single ultra‑high‑efficiency stage. At 100 MW, the recovered power is enough to run 34% more GB200‑class racks without increasing the power budget.
Cool-E is ready for the higher flow demands of GB200, Rubin, and what's next
Nvidia’s Rubin's throughput scales roughly 10x, every recovered megawatt becomes exponentially more valuable. Cool-E answers with an added motor branch instead of pushing amperage harder while competitors scale flow through the same motors, so their amps climb faster.

How Cool-E Unlocks More Compute
Facility electrical service is a fixed budget. Cooling and IT share it. Induction motors need a large NEC 430 (125%) safety margin on their circuits; that margin is capacity the site paid for but cannot use. Cool-E's permanent magnet motors need a much smaller margin, so the difference is freed for IT without a utility upgrade.
As AI rack density increases, recovered power becomes more valuable
Nvidia’s Rubin makes Cool-E even more valuable. Rubin requires significantly more coolant flow than NVIDIA's GB200, increasing the electrical demand on conventional cooling systems. Legacy induction motor systems deliver that extra flow by driving the same motors harder, causing MCA to nearly double from 157A to 314A. Cool-E instead adds another permanent magnet motor operating at its optimal efficiency point, increasing MCA from just 27A to 49A.
While Cool-E maintains its 83% to 84% MCA advantage, the real benefit is that the absolute amp savings nearly double, from 130 amps recovered with GB200 to 265 amps with Rubin. Those recovered amps are what drive the projected annual financial impact from $30M to $81M with GB200 to $70M to $189M with Rubin in a 100 megawatt facility.

DC-native cooling. Same footprint, less amperage, more compute.
Dramatically lighter upstream electrical infrastructure By cutting MCA roughly 60% at the plant level, Cool‑E MCS enables much smaller conductors, panels, and switchgear than a 480 V AC, VFD‑heavy baseline. Wire gauge can step down for a like‑for‑like copper reduction approaching 80% in line runs, with correspondingly lower I²R losses and thermal loading. With no VFDs and no climate‑driven amp escalation, electrical design can be sized for steady‑state current only, simplifying coordination and compressing construction timelines.
Power‑agnostic — no site prerequisite Cool‑E MCS accepts 3‑phase 340–528 VAC or 500–850 VDC natively, so it drops into today’s AC plants and tomorrow’s DC backbones with the same hardware. Facilities can start on AC, then migrate to DC distribution when ready without touching the CDU, avoiding AC→DC rectifier losses and preventing cooling assets from becoming stranded during power‑system transitions.
Configurable CDU architecture, consistent efficiency Whether deployed in‑row, row‑end, or at pod/plant scale, the Cool‑E Modular Cooling System keeps the same DC‑native architecture and efficiency gains. Standardized modules accelerate design and installation, and once online, energy that would have disappeared into drives, losses, and oversized copper is continuously reallocated to IT where it directly translates into more GPUs at full utilization.
Optimized ΔT cuts pump energy per MW Magnetic‑drive hydraulics and tight thermal control support a 15–20 °F ΔT where conventional induction‑pump systems typically run 10–15 °F. Higher ΔT means more heat rejection per gallon of coolant, fewer gallons per MW, and meaningfully lower pump kW for the same cooling duty. The result is higher plant COP and more of the facility’s nameplate power available for compute.
