Non-spill self-aligning couplings CGO and CGD

At the heart of liquid-cooled electronic systems, the non-spill technology of CGO and CGD couplings guarantees perfect sealing during operation, connection and disconnection. Mounted on rackable systems, these couplings are designed to compensate for alignment faults of up to 0.5 mm with the CGO’s oscillation technology and up to 1 mm with the CGD’s displacement technology.

Applications: Electronic cooling of converters, data centers, radar equipment, medical imaging equipment, etc.
