In the world of hyperscale data centers, rack-level liquid cooling is quickly becoming a defining technology. As densities rise and thermal management demands intensify, reliability, ease of service, and leak-free operation become nonnegotiable. That’s where Hydraquip is proud to partner with Danfoss. As a Danfoss Premier Partner, Hydraquip delivers state-of-the-art solutions like the new UQD couplings, designed specifically for the rigors of data center rack cooling.
Why UQD Couplings Matter for Data Center Racks
Danfoss recently launched Universal Quick Disconnect (UQD) couplings that are engineered for cooling applications in dense, critical computing environment. Below are key features making UQD couplings stand out:
- High corrosion resistance and broad fluid compatibility: Constructed of stainless steel with EPDM rubber seals, they tolerate a wide range of coolant chemistries while resisting corrosion over time.
- Flat-face, dry-break design: This limits any fluid spillage during coupling/disconnection, a must when uptime is essential.
- Push-to-connect, tool-free operation: The design enables one-handed coupling and uncoupling, simplifying maintenance and service in tight rack environments.
- Low pressure drop, high flow performance: UQD couplings deliver ~ 25% higher flow than Open Compute Project (OCP) community standards, while keeping pressure losses down.
- Helium leak-tested for assured integrity: Every coupling undergoes testing to ensure leak rates are negligible, giving operators confidence for critical deployments.
In short, UQD couplings bring durability, performance, safety, and ease-of-use to the fluid interconnect layer in data centers, making them especially well-suited to today’s rack-level cooling architectures.
The Data Center Imperative: Why Couplings Can’t Be an Afterthought
Modern data centers push the envelope in terms of power density, heat flux, and the need for continuous, uninterrupted operations. Cooling failures or fluid leaks represent a serious risk to assets and business continuity. In that context:
- Space constraints & compact routing
Racks are densely packed. Every millimeter of clearance matters. The compact footprint of UQD couplings allows tighter routing, shorter hose lengths, and less overall plumbing overhead. - Modularity, scalability, and serviceability
Data center operators often need to upgrade or service at the rack level with minimal disruption. The push-to-connect, tool-free design means technicians can swap modules or perform maintenance quickly and cleanly without shutting down entire systems. - Efficiency and energy consumption
Any added pressure drop in the cooling loop translates to extra pumping power (and hence more energy use). UQD’s low-pressure-drop design helps reduce parasitic losses in the cooling path and thereby contributes to lower operational costs. - Reliability and leak prevention
Given the mission-critical nature of compute hardware, fluid leaks are not just inconvenient, they’re dangerous. The flat-face, dry-break, and leak-tested design features of UQD reduce risk, helping maintain continuous operation with minimal risk of fluid ingress into electronics. - Standards compliance and interoperability
The UQD’s performance exceeds the OCP community benchmarks by about 25%, facilitating integration into future-forward data center architectures designed around open standards.
Because of all these pressures, data center operators must no longer treat couplings as “pipe fittings” to be shoehorned in. They must be designed, tested, and integrated components of the cooling system, and that’s exactly where Danfoss, with support from Hydraquip, brings value.

Use Cases: How UQD Excels in Rack Cooling Environments
To illustrate, here are a few scenarios where UQD couplings shine in data center deployments:
- Hot-swappable rack modules
Imagine a rack-level liquid cooling manifold with modular cold plates or pump modules that might be replaced in the field. A tool-free, one-hand disconnect coupling means technicians can perform replacements quickly without field leakage or cross-connection risk. - Vertical rack coolant risers
In tall racks or multi-unit stacks, vertical distribution headers often require detachable connections. UQD couplings simplify stacking and modular interconnects while maintaining performance and leak safety. - Redundant cooling loops
High availability designs often include parallel cooling loops or redundant header arrangements. Using couplings that support quick isolation and reconnection ensures maintenance or failover operations can proceed smoothly. - Retrofit of existing racks to liquid cooling
Many operators upgrade from air or hybrid cooling to liquid-cooled racks. UQD couplings can be retrofitted into existing plumbing layouts without extensive rework, enabling a smoother transition.
