    TURNING WASTE HEAT INTO A
    VALUABLE RESOURCE

    Data center operators are no longer focused solely on improving cooling system efficiency metrics such as PUE or WUE. The expectation is now engineering thermal management systems to enable heat recovery and beneficial reuse. Rather than rejecting waste heat through dry coolers or cooling towers, facilities are integrating high-temperature return water loops designed to export usable thermal energy to secondary applications, such as district heating networks or adjacent industrial processes.

     

    This transition materially impacts CDU architecture. Systems must now be designed to support elevated supply and return temperatures, tighter thermal control bands, and hydraulic configurations that maintain IT inlet temperature stability while maximizing heat extraction quality. It also introduces additional considerations around heat exchanger sizing, materials compatibility, pressure management, redundancy strategy, and control system integration to ensure reliable operation across both the IT load and the downstream heat consumer interface.

    DATA CENTER PUMPS

    Gates Data Center Pumps excel in CDU applications with their advanced axial flux BLDC motors, delivering up to 25% higher efficiency than traditional designs while achieving flows up to ~400 L/min in high-power models (100–2500W) and exceeding 1500 L/min in ultra-high-power variants (2.5–25kW).

     

    The compact, lightweight, and customizable axial flux designs provide superior power-to-volume ratio for tight in-rack or in-row CDU footprints, and ensure broad compatibility with glycol-based and di-electric coolants.

    FREQUENTLY ASKED QUESTIONS

    Expand All / Collapse All

    A CDU is a specialized system that regulates and distributes coolant in liquid cooling architectures, isolating the facility water system (FWS) from the technology cooling system (TCS) to manage flow, pressure, temperature, and quality for high-density servers.

    In CDU internal circulation, Gates data center pumps drive closed-loop coolant flow, ensuring precise pressure/ temperature control and up to 25% efficiency gains over traditional designs.

    In-rack CDUs mount within server racks for modular, high-precision cooling, ideal for dense AI setups but space-limited; row-level CDUs serve multiple racks in an aisle, offering scalability with easier maintenance; facility-level CDUs handle entire data halls, centralizing control but requiring extensive plumbing.

    Quick disconnects like Gates UQD couplings enable dry-break disconnection convenience while handling up to 290 psi working pressure to support high-density racks without sacrificing flow or durability.

    CDUs commonly support glycol-based coolants and di-electrics. Glycol suits direct-to-chip for cost-effectiveness, while di-electrics enable non-conductive immersion.

    In immersion cooling, CDUs circulate dielectric coolants through tanks with the help of Gates data center pumps, providing scalable flows and efficiency for single and two-phase systems.

    Redundant loop plumbing uses N+1/N+2 pump configurations like Gates data center pumps and UQDs for spill-free switching via dual-interlock and 1/4-turn isolation. This minimizes downtime in high-energy loops, ensuring continuous cooling.

    Yes, Gates offers custom hose designs, thermal-molded tubing, and personalized pump configurations to meet your specific needs.

    Challenges include leak risks, coolant contamination, and scalability. These can be mitigated with negative-pressure CDUs or robust components like Gates pumps/QDs for monitoring and dry-breaks.

    Hoses made with premium materials, like Gates MegaFlex technology, resist kinks, cracks, and aging, ensuring long-lasting performance.
