LQC couplings

OCP (Open Compute Project) Liquid cooling Dry break

The Large Quick Connector (LQC) 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. Screw-to-connect locking mechanism, effortless connection even under working pressure up to 5 bar, double redundant O-ring seal for extra leak prevention are just some of the features that makes this coupling solution ideal for Data Center Coolant Distribution Units (CDUs).

Technical data

Nominal flow diameter (mm) 19 mm
Max working pressure (bar) 12 bar
Material coupling Stainless steel (AISI 303)

Interchangeable coupling solution for data center CDU connections

The OCP LQC is an interchangeable coupling solution specially designed for Coolant Distribution Units (CDU), developed within the OCP initiative. As most CDUs require users to connect and disconnect their quick connect couplings during operation, the screw-to-connect operation of OCP LQC provides better usability than the push-to-connect type quick connect couplings as this can be done while being under working pressure up to 5 bar.

As an open standard, any manufacturer’s products are connectable by following the specifications of the LQC standard. With CEJN high precision manufacturing and long experience in high-quality quick disconnect couplings for various applications, our LQC quick couplings are guaranteed to meet and exceed the standard specifications.
