LQD Quick Couplings

In 2026, Stäubli is set to launch a groundbreaking quick coupling solution: LQD. Combining the compact size of the UQD04 with the exceptional flow performance of the UQD08, LQD is designed to meet the evolving demands of high-density, AI-driven data center cooling systems.

Meeting customer needs with a new, high-performance coupling for liquid cooling

As AI workloads increase, racks are becoming thinner while power density rises. Cooling systems must deliver higher flow rates to dissipate more kilowatts efficiently, without compromising space or reliability. Traditional solutions often lead to pressure drops and reduced performance across entire cooling loops, especially in cabinets with hundreds of connectors.

Why to choose Stäubli's LQD?

LQD is the answer to these challenges:

✔ Compactness of UQD04 – Ideal for space-constrained environments

✔ Flow performance of UQD08 – Ensures optimal cooling capacity

✔ Lower pressure drop in both directions – Reduces energy consumption and improves system efficiency

Within the UQD04 form factor, LQD delivers 900%* pressure loss reduction, enabling better thermal management and supporting the next generation of AI infrastructure.

*Based on R&D performance testing

Adapt your racks to fit AI requirements. 

More flow, more cooling, more performance. LQD is your choice.
