UQDB couplings

OCP (Open Compute Project) Liquid cooling Dry break

The Universal Quick Disconnect blind-mate (UQDB) coupling for data center applications is developed within the OCP (Open Compute Project) initiative, an initiative that has established a new global standard within the data center industry community for quick connect couplings. Compact design, blind-mate function and +/- 1 mm radial misalignment tolerance are features that makes this coupling solution a perfect fit for Direct Liquid Cooling (DLC) applications within the data center segment.

Technical data

Nominal flow diameter (mm) 3.20, 6.40 mm
Max working pressure (bar) 10 bar

The universal quick disconnect blind-mate coupling for DLC applications

CEJN has long experience in quick coupling technology for thermal management, and our expertise has made us one of the contributors to the Open Compute Project (OCP) – a collaborative community developing interchangeable quick coupling solutions for liquid cooling systems.

The OCP UQDB is a non-drip quick connect coupling solution with blind-mate function developed within the Open Compute Project (OCP) initiative. Together with its compact design and +/- 1 mm radial misalignment tolerance, it is a perfect fit for Direct Liquid Cooling (DLC) applications within the data center segment.
