DDC S-Series rack containment

Your racks are running hotter. Your cooling architecture hasn’t caught up.

The DDC S-Series delivers rack-contained precision cooling from 1–100kW air-cooled and a clear upgrade path to 1MW+ per rack — built for the AI era, without rebuilding your data center.

  • GPU asset protection built in
  • No raised floor required
  • Per-cabinet fire suppression
  • Liquid-to-chip ready — 1MW+ per rack

    1–100kW air-cooled per cabinet, same platform
    1MW+ upgrade path per rack, liquid-to-chip ready
    NEMA 3R rated — IT stays dry during suppression events
    <2°F temp variance top-to-bottom — extends GPU life
    Fire Suppression built into each cabinet
    Hours to deploy — no raised floor build-out required

    The problem

    Room-level cooling wasn't built for this

    Modern AI and HPC workloads are pushing rack densities beyond what traditional cooling architectures were ever designed to handle. Hot spots, over-provisioning, and thermal stress aren’t just operational headaches — they’re actively shortening the life of your most expensive hardware. The S-Series puts precision cooling where it matters: inside every cabinet.

    Your GPUs are worth protecting

    GPU hardware is your most valuable infrastructure investment. Traditional cooling architectures expose that investment to thermal variance, hot spots, and suppression events that can take down an entire room. The S-Series eliminates all three.

    THERMAL PRECISION

    Less than 2°F variance top-to-bottom — fewer thermal cycles, longer component life and improved MTBF on GPU hardware.

    WATER INGRESS PROTECTION

    NEMA 3R sealing keeps IT equipment dry during overhead suppression events and chilled water line failures.

    CONTAINED FIRE SUPPRESSION

    Per-cabinet FK5-1-12 mechanical system — activates at ~100°C, localised to one rack. Adjacent cabinets stay online.

    What changes when cooling lives inside the cabinet

    Traditional room cooling DDC S-Series rack-contained
    Room-level temperature management
    Per-cabinet precision control, independently managed
    Hot spots and failures above 20kW
    Consistent cooling from 1kW to 100kW+
    Raised floor + CRAC infrastructure required
    No raised floor — connect water, power, and go
    Suppression event can take down the room
    Risk contained to one cabinet, adjacent racks stay up
    Thermal stress shortens expensive GPU hardware life
    <2°F variance protects your hardware investment
    Months to build out, difficult to scale incrementally
    Operational in hours, scales one cabinet at a time
