Danfoss Hansen Universal Quick Disconnect Blind-Mate (UQDB) has been designed with OCP (Open Compute Project) community to set industry standard for thermal management application in data centers. This quick disconnect coupling is available in 4 dierent sizes (as the UQD: -02/-04/-06/-08) and complies with OCP specication requirements. Danfoss UQDB oers a self-alignment feature to help connect in location with limited access or visibility and guarantees 100% helium-leak testing on every coupling.

Features and Benefits

- Designed per OCP UQDB specications
-“Blind-connection” thanks to self- alignment feature with radial compensation of 1 mm
- Push-to-connect design
- Direct connection between servers and manifolds
- High ow and reduced pressure drop for an improved system eciency
- Flat-face dry break design to avoid spillage during connection/ disconnection
- Sizes available: -02/-04/-06/-08
- High reliability and 100% helium-leak tested
- Standard material: 303 stainless steel for excellent corrosion resistance
- Standard seal material: EPDM for excellent uid com-patibility
- Terminal ends are ORB
- Operating temperature: 10°C - 65°C (50°F - 149°F)
- Working pressure: min. 10 bar
- QR code marking to help identify and track produc-tion parts
