The HaloDrive™ Cooling Engine is a purpose-built thermal platform for the AI era—engineered to eliminate bottlenecks, slash energy waste, and unlock new levels of sustainable performance. By replacing inefficient mechanical cooling architecture with a rare-earth-free, ferrite-based axial-flux motor-pump system, it transforms cooling from a parasitic load into an active energy asset, delivering 80–90% wire-to-fluid efficiency and up to 2 MW of direct-to-chip cooling in a compact, modular footprint.

Designed for next-generation AI, HPC, and OCP/Deschutes-class data centers, the Cooling Engine combines propulsion-grade electrification with bidirectional SiC inverter-based DC grid integration—capturing energy that legacy CDUs waste and returning it to the system like regenerative braking in an EV. This breakthrough approach reduces operating costs, improves sustainability, and strengthens long-term supply-chain resilience by eliminating rare-earth dependencies.

With robust modularity, high reliability, and support for advanced DC microgrid ecosystems, HaloDrive enables hyperscale operators to scale faster, reclaim rack-level space and power for compute, and save millions annually—setting a new benchmark for efficiency in high-density AI data centers.

The HaloDrive Cooling Engine is engineered for efficiency, sustainability, and the compute demands of today and the future.
