MEET

the hpu

one system. zero compromises.

Our heat processing unit (HPU) architecture works efficiently with gigascale AI factories in any location or ambient conditions. HPUs interact with heating, cooling, and power streams of the facility to optimize the Power Utilization Effectiveness (PUE) of the facility.

Key differentiators

Lowest Peak PUE on the Market

In hot ambient conditions, HPUs provide the most efficient cooling with zero water consumption, unlocking stranded compute.

Lowest Average PUE on the market

In colder ambient conditions, HPUs process waste heat from compute racks to provide additional cooling, electricity, or high-grade heat for district heating and other use cases.

High Capacity Production

Our first factory, GigaWerx, will produce 1GW of systems per year starting in Q3 2026. Additional factories will come online in 2028.

Future Proof Working Fluid

Our system utilizes CO2, a natural-refrigerant as our working fluid with a Global Warming Potential (GWP) of 1 and doesn’t form “forever chemicals” (PFAS), future-proofing deployments from any regulatory restrictions.

High Density and Reduced Infrastructure

10MW HPUs simplify site design, dramatically reducing the number of units to be installed, piped, and wired on-site.

Maximize AI ROI

Optimizing thermal architecture to maximize resource allocation towards compute.

Radical Footprint Reduction

Shrinks the exterior mechanical yard by 60% to 80%, freeing up valuable land for additional compute capacity.

Zero Water Use

HPUs have eliminated the need for water consumption to match future data center architectures where massive water consumption is not an option.

POWERED BY THE KARMAN KOMPRESSOR

HPUs integrate our proprietary high-speed KOMPRESSOR leveraging 800V DC architecture while borrowing the latest innovations in rocket turbomachinery like metal 3D-printing, and electric vehicles innovations like high speed motors & Silicon-Carbide power electronics technology

Highly compact package fitting 10MW of thermal power inside a single shipping container.

High-speed variable speed drive to take advantage of CO2’s unique properties.

3D printed impellers and stator vanes to deliver high performance.

Non-contact bearings eliminates wear and tear for ultra-low OPEX and reduced downtime

INNOVATION WHERE INNOVATION
IS NEEDED.

Traditional designs require sprawling mechanical yards filled with 500+ disparate chillers and dry coolers, necessitating miles of complex piping and months of on-site assembly.

We’ve moved beyond the era of legacy chillers to HPUs. By shrinking the footprint of the mechanical yard by 80%, we don’t just save land; we eliminate the ‘snowball effect’ of infrastructure complexity, allowing hyperscalers to move from 'shovels in the ground' to 'chips in the rack' many months faster while unlocking additional compute.

Our dramatic reduction in PUE unlocks stranded compute and allows for more of a sites power to be used towards IT vs non-IT. This translates to massive increases in revenue.

Why CO2 Is the

gold Standard

for thermal working fluids

Many widely used refrigerants have high Global Warming Potential (GWP) and/or degrade into PFAS (‘forever chemicals’), which accumulate in the environment and can be toxic. Our HPUs utilize a natural refrigerant and unlocks increased performance due to our proprietary design.

CO₂ stands out as a natural refrigerant for its minimal climate and health impact, regulatory resilience, safety, insurance and operational benefits making it the gold standard for sustainable refrigeration.
