Engineered CDU systems for high-density compute.
CDU skids, direct-to-chip cooling, and immersion platforms — from 300kW to 20MW+, designed, integrated, and delivered for OEMs and operators.
How CDU Systems Integrate
A closed liquid loop links facility cooling, the CDU, in-row distribution, and the racks — moving heat from compute back to facility heat rejection.
CDU Systems
Coolant distribution units engineered, fabricated, and tested as complete skid systems. From facility-water-to-IT loops at 300kW to multi-megawatt deployments serving high-density AI compute halls.

Immersion Cooling Systems
Single-phase and two-phase immersion cooling platforms. Tank systems, dielectric fluid handling, filtration loops, and heat rejection — built to support extreme rack densities.
- Single-phase (1P) and two-phase (2P) configurations
- Dielectric fluid handling and polishing loops
- Condenser and heat rejection integration
- Sensor, monitoring, and controls infrastructure
How CDU Systems Work
A CDU isolates the IT-side coolant loop from the facility water loop, exchanging heat through a liquid-to-liquid heat exchanger while controlling flow, pressure, and chemistry on the technology side.
Heat Capture
Cold technology coolant enters cold plates or immersion tanks, absorbing heat directly from CPUs, GPUs, and accelerators.
Heat Transfer
Warm coolant returns to the CDU, where a brazed-plate heat exchanger transfers thermal energy to the facility water loop.
Heat Rejection
Facility water carries heat to the chiller plant, dry cooler, or cooling tower, while conditioned coolant recirculates to the racks.
