Data center liquid cooling UQD blind mate coupling

Data center liquid cooling UQD blind mate coupling

Data center world standard compliant rack-mounted server embedded coupling.

The universal quick disconnect blind mate (UQDB) coupling for data centers is a non-drip quick connect coupler with blind mate functionality developed within the Open Compute Project (OCP) initiative. We are one of the manufacturers that developed this global standard. With no dripping during connection and disconnection, a compact design, blind mate functionality, and a tolerance of ±1mm for axial and perpendicular misalignment, it is ideal for liquid cooling (DLC: Direct Liquid Cooling) applications in the data center field.

Safe and high-performance quick connect couplings for hydraulic, pneumatic, and fluid applications.

Safe and high-performance quick connect couplings for hydraulic, pneumatic, and fluid applications.

Please consult with us regarding issues such as liquid dripping during disconnection, misconnection of pipes, and hose flailing. Improve the efficiency and safety of your workspace with high-performance couplers!

Since its first patented coupling was launched in 1955, Sain has been manufacturing safe and high-quality products for over 60 years. It has established itself as a standard manufacturer in the European market and currently sells in 17 locations worldwide. ■ How Sain products can contribute to solving customer challenges ■ 1. Optimize energy efficiency - contributing to energy savings High-quality couplings and air guns with excellent flow characteristics and designs that minimize pressure loss reduce unnecessary costs. 2. Safe connection and disconnection - contributing to workplace safety Air couplings with residual pressure removal mechanisms, slow-retracting hose reels, and misconnection prevention couplings eliminate accidents. 3. Drip-free product design - reducing environmental pollution For chillers, drip-free liquid cooling couplings prevent the leakage of refrigerants with high global warming potential. Choosing hydraulic couplings that do not leak oil for construction machinery can reduce environmental impact. 4. High durability, repairability, and ease of maintenance - reducing running costs We pursue coupling structures that are easy to maintain. A wide range of hoses and spare parts is also available.
