BMQC couplings
OCP (Open Compute Project) Liquid cooling Dry break
The Universal Blind-Mate Quick Connector (BMQC) 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. Its compact design, blind-mate functionality, and impressive tolerance for radial misalignment of +/- 5 mm, together with an angular misalignment tolerance of +/- 2.7°, it is the perfect fit for Direct Liquid Cooling (DLC) setups in the data center segment.
Technical data
| Nominal flow diameter (mm) | 5 mm |
| Max working pressure (bar) | 3.45 bar |
| Main material | Stainless steel (AISI 303) |
Experience extra high misalignment tolerance with OCP BMQC
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 BMQC obtains the same great features as the OCP UQDB. Still, instead of +/- 1 mm misalignment tolerance, the OCP BMQC has an extra high tolerance of +/- 5 mm radial misalignment and +/- 2,7° angular misalignment.
Features
- Interchangeable with OCP BMQC
- Spill-free
- Compact design
- +/- 5 mm radial misalignment tolerance and +/- 2,7° angular misalignment tolerance
- UL-IEC 62368-1 approved EPDM seal
- BSP(G)/NPT threads as standard connections, possible for other connections upon request
