Data Center Cooling Applications

With precise valve, sensor, and control technology, Bürkert enables efficient liquid cooling solutions for modern data centers. Individually controllable coolant distribution at rack and server level ensures safe operation, high system transparency, scalable architectures, and energy-efficient cooling for increasing power densities.


On the cooling side, Bürkert control valves, angle-seat valves, and valve islands precisely regulate flow and pressure in chiller loops, CDUs, manifolds, rear-door heat exchangers, and direct-to-chip or immersion systems, maintaining safe chip temperatures and preventing hot spots. FLOWave and other flowmeters deliver low–pressure-loss, maintenance-friendly measurement, improving pump efficiency and enabling tighter capacity control, while robust materials and modular designs reduce unplanned downtime and simplify expansion. Integrated digital communication (e.g., Ethernet/IP, Modbus, IO‑Link) lets these devices plug into BMS/DCIM platforms for real-time monitoring, alarming, and optimisation.

 

 

Coolant Distribution Units (CDUs) for Liquid-Cooled Data CentresCoolant Distribution Units (CDUs) for Liquid-Cooled Data Centres

A Coolant Distribution Unit (CDU) is a skid‑ or rack‑mounted system that manages liquid between the building side (chilled or condenser water) and the IT side (direct‑to‑chip loops, manifolds or immersion tanks) in a closed secondary circuit. Pumps, heat exchangers, filters, expansion volume and controls regulate temperature, flow and pressure for high‑density liquid cooling. In a positive‑pressure CDU the IT loop is kept above ambient pressure so coolant is pushed through cold plates and manifolds; if a leak occurs, fluid escapes outward rather than air being drawn in, which is the classic alternative to negative‑pressure (vacuum) designs.

 

 

For water quality and sustainability, Bürkert’s 8906 Water Quality Analysis System, multi-parameter controllers like Type 8619, and a portfolio of conductivity, pH, ORP, turbidity, and temperature sensors continuously monitor make-up water, RO/ DI systems, and cooling loops. This supports proactive treatment, protects heat exchangers and piping from scale, corrosion, and biofouling, and helps operators track KPIs such as WUE and blowdown optimisation. In power and “new energy” applications, proportional valves, mass flow controllers, and gas-rated valves and sensors enable precise, safe handling of hydrogen, fuel-cell media, or auxiliary fluids, aligning backup power with low-carbon goals.

 

Across all these areas, the common thread is digital, decentralized automation: local intelligence in valve heads and controllers, rich diagnostic data, and easy network integration. That combination allows data centers to run cooler, cleaner, and smarter, with higher uptime, lower operating costs, and a clearer path to sustainable, high-density operation supported by Bürkert’s fluid-control expertise.
