Data Centers

AI is transforming data centers into highly complex power and cooling infrastructures. As operators face increasing energy demand, liquid cooling requirements and multi-vendor system complexity, accurate measurement and coordination across infrastructure systems are becoming critical.

Yokogawa brings together precision measurement, industrial control, data integration and energy management expertise to help customers understand, connect and optimize the infrastructure that keeps AI data centers running. From power and cooling systems to facility operations and energy management, Yokogawa supports more reliable, efficient and sustainable data center operations.

Operate Data Centers, Not Infrastructure

Enable operators to focus on business outcomes and uptime instead of managing complex power, cooling, water, and automation infrastructure.

Liquid Cooling Performance Monitoring

Detecting abnormalities and performance degradation in liquid cooling systems.

Power Efficiency & Optical performance validation

Ensuring accurate validation of power efficiency and optical performance in next-generation data center components.

From Monitoring Data to Better Optimization

Integrate and utilize monitoring data to optimize power and cooling systems, enabling operators to better understand changing conditions and improve energy efficiency(PUE).

Solutions

• Integrate and unify data: Multi-source data integration and unified data model enable holistic optimization.
• Control from monitoring to action: Real-time monitoring of local critical assets enables continuous visibility of load fluctuations and dynamic adjustment of cooling and power systems.

Benefits

• Unified visibility
• PUE improvement
• Improved operating efficiency

Real-Time Thermal Visibility for Power Distribution Lines

Ensure better visibility into thermal conditions in busbars and power cables to enable earlier issue detection and better use of existing cable capacity.

Solutions

• Detect abnormal heat: Eliminate blind spots inherent to point-sensors. Deploy miles of continuous fiber optic cable to track real-time, linear temperature profiles along power busbars and cable trays, locating thermal anomalies to the exact meter.
• Assess cable temperature and capacity in real time (Real-Time Thermal Rating): Dynamic assessment of conductor temperature and available cable capacity under actual operating conditions.

Benefits

• Improved thermal visibility and early hotspot detection
• Improved utilization of existing power cable capacity

Precision Sensing for Liquid Cooling Performance Monitoring

Help cooling equipment manufacturers clearly monitor liquid cooling conditions through precise measurement of flow, temperature, pressure, and liquid properties, enabling earlier detection of abnormalities and performance changes.

Solutions

• Monitor coolant degradation and chemistry in real time: Continuous liquid analysis safeguards your infrastructure against scaling, corrosion, and biological growth within cooling towers and secondary fluid loops, extending the lifespan of mission-critical mechanical assets.
• Verify sub-loop flow and mass balance: Ensure exact dielectric fluid and chilled water delivery across Cooling Distribution Units (CDUs). Accurately measure flow velocity and balance to maximize heat exchanger efficiency and instantly flag line restrictions.
• Track ultra-low delta-T thermal conditions: In liquid-cooled architectures, monitoring tight temperature differentials across the primary and secondary loops is critical. Detect micro-changes in coolant temperature to prevent localized hot spots before they trigger automatic server throttling.

Benefits

• Cooling loop visibility
• Early detection of abnormalities and performance changes
• Stable cooling performance
