Engineered for high-flow efficiency and drip-free performance, MQDB couplings are the premier solution for rack-level liquid cooling requiring blind-mate integration and precise radial displacement tolerances during assembly.
SWAK offers the MQDB Series, available in MQDB02, MQDB03, and MQDB04 sizes. Engineered for the rigorous demands of HPC and AI data centers, the MQDB series is specifically optimized for single-phase liquid cooling systems—utilizing Propylene glycol or ethylene glycol—to ensure efficient thermal management for mission-critical electronic components.
Designed to be fully compliant with NVIDIA’s technical standards, the MQDB series facilitates effortless blind-mate integration within modular rack architectures. By combining an ultra-compact form factor with SWAK’s renowned high-precision manufacturing, these couplings offer a robust, leak-free interface that allows for automatic alignment and rapid server deployment in high-density, compute-intensive environments.
✓ NVIDIA Standards Compliance: Fully engineered to meet and exceed NVIDIA’s rigorous technical standards for AI and high-density computing ecosystems.
✓ Precision Blind-Mate Design: Optimized for direct slide-in rack integration, enabling seamless, tool-free connection in restricted-access environments.
✓ Advanced Alignment Tolerance: Features an allowable X, Y radial displacement of ±1 mm, ensuring reliable coupling and automatic self-alignment during server installation.
✓ High-Efficiency Fluid Control: Optimized for high flow rates with a guaranteed non-spill interface to protect mission-critical electronic components.
✓ Leak-Free Valve Technology: Equipped with precision double shut-off flat-face valves to ensure zero fluid loss during connection and disconnection.
✓ Ergonomic Mechanical Advantage: Delivers best-in-class force-to-connect, reducing mechanical stress on server chassis and rack manifolds.
✓ High-Performance Sealing: Utilizes standard EPDM-P (peroxide-cured) seals for exceptional chemical resistance and long-term stability in water-glycol systems.
✓ Robust Material Integrity: Manufactured from premium stainless steel to ensure broad fluid compatibility and superior corrosion resistance.
