Liquid cooling is now a must‑have for modern data centers supporting AI, IoT, and edge infrastructure. But uptime depends on quick‑connect reliability. That’s why CEJN’s OCP (Open Compute Project) couplers—LQC, UQD, UQDB, and BMQC—are the gold standard for CDU and DLC applications.
At Catawba Industrial Rubber Company, we’re proud to be your trusted partner in delivering, configuring, and supporting CEJN solutions—backed by inventory, speed, and expert support.
Why CEJN OCP Couplers Matter
- OCP‑compliant modular design: Ensure seamless interchangeability across CEJN and partner products—no compatibility headaches.
- Screw‑to‑connect LQC: Preferred for CDU-level maintenance, allowing connection/disconnection under pressure up to 5 bar with double O-ring seals and stainless-steel durability.
- Blind‑mate UQDB and BMQC: Designed for Direct Liquid Cooling. Spill‑free, compact, and forgiving of misalignment (± 1 mm or up to ± 5 mm / ± 2.7°), enabling hot-swaps with no shut-down.
