Boost data center cooling systems with Memosens technology

Modern data centers face significant challenges in managing their cooling systems due to the rapid increase in power and cooling demands driven by AI and machine learning applications. As data centers move from using CPUs to GPUs, it necessitates a change from air-cooling to liquid-cooling of the server racks which increases the demand for more precise monitoring instrumentation.

Endress+Hauser provides a comprehensive instrumentation solution for building efficient cooling skids. The Liquiline CM444 multiparameter controller, Memosens CLS82E conductivity sensor, Memosens CUS52D turbidity sensor and Memosens CPS11E pH sensor are integrated into the cooling skids to deliver real-time, precise measurements.

Liquid cooling is far more efficient than air cooling for modern data centers. It removes heat up to 1,000 times better, reduces energy use by minimizing HVAC loads and saves space with compact systems. While upfront costs may be higher, liquid cooling lowers PUE, supports sustainability and delivers long-term savings for GPU-intensive workloads.

Data centers are cooled using systems that remove heat generated by servers and IT equipment. Traditional methods rely on air cooling with HVAC units and raised floors, while modern facilities increasingly use liquid cooling for high-density workloads. Techniques include chilled water systems, direct-to-chip cooling, immersion cooling and hot/cold aisle containment to maintain optimal temperatures and energy efficiency.

Endress+Hauser helps improve efficiency with advanced liquid analysis solutions. Instruments like the Liquiline CM444 controller and Memosens sensors (CLS82E for conductivity, CUS52D for turbidity, CPS11E for pH) provide real-time monitoring and diagnostics. This ensures optimal water quality, prevents scaling and supports predictive maintenance—reducing energy consumption and operating costs.
