As the demand for high power density servers grows, so does the need for efficient liquid cooling that keeps systems within optimal operating temperatures. Optimizing pump technology is key to improving system performance and reducing energy consumption.
Our intelligent pumps are designed to match cooling and computing loads with precision. With integrated high-efficiency motors and advanced control modes, they enable demand-driven operation that eliminates energy waste and reduces water consumption, particularly during low-load conditions.
Key features include:
Variable-speed operation for minimal energy consumption, especially under low loads, eliminating the need for liquid bypass.
Intelligent cascading in multi-pump setups ensures pumps operate close to their best efficiency point, even as cooling demands fluctuate. Incorporating active redundancy in these setups can help maintain cooling without an external controller – which is critical when the time between CDU pump failure and processor throttling can be as little as 23 seconds, according to the ASHRAE TC 9.9 Technical Bulletin on Liquid Cooling.
Direct Sensor technology provides fast response and precise temperature-controlled variable-speed pumping for optimal coolant flow.
Integrated control logic simplifies installation by automatically adjusting to local temperature variations, ensuring constant temperature while reducing energy use.
Built-in temperature control programs streamline installation and debugging, making it easier to achieve higher efficiency and reliability in cooling operations.
NBE & CME – proven, efficient and intelligent solutions
Grundfos NBE and CME pumps are built on five decades of experience in delicate cooling applications, ensuring reliability and efficiency. These intelligent E-pump solutions adapt to real-time demand, minimising lifecycle costs and CO2 emissions.
- Integrated pump, motor and VFD for the most efficient demand-driven operation.
- Advanced algorithms for differential temperature, differential pressure control, differential pressure and constant temperature control.
- Optimized for liquid cooling fluids commonly used in the secondary loop in data centers, including handling high-viscosity fluids at operating temperatures from 20°C to 50°C, with some data centers reaching return temperatures as high as 61°C.
- Quick tri-clamp connections on NBE pumps save space by removing the adapters they need to connect the pump’s flanges with their clamps and do the fittings while also simplifying retrofits and replacements.
- Pre-fitted sensors available for NBGEs and CMEs, streamlining installation and monitoring.
