A Sector in Transformation, Driven by AI and Increasingly Dense Workloads
CDU equipped with Dyneo+ motors (Illustration AI).
Data centers are now the essential infrastructure for the cloud, artificial intelligence, and real-time digital services. With the rise of data centers that use GPUs rather than CPUs to achieve massive computing power, thermal management has become a major strategic challenge, as GPUs generate significantly more heat. PUE (Power Usage Effectiveness), the benchmark indicator of energy efficiency, proves this: up to 40% of a data center’s total energy consumption can be attributed to its cooling system.
To remain competitive, operators must therefore optimize every kilowatt, ensure operational continuity, and adapt their architecture to increasingly advanced cooling technologies: containment, in-row, rear-door, direct-to-chip liquid cooling, or immersion.
Leroy-Somer’s expertise: decades at the heart of cooling systems
With decades of expertise in the motorization of fans, pumps, hermetic and semi-hermetic compressors, and refrigeration systems, The Leroy-Somer brand has become a benchmark in these sectors, enabling it to meet the requirements of CDU manufacturers as well.
Our solutions, recognized for their technical and energy efficiency as well as their eco-friendly design, cover all the thermal needs of data centers, integrating seamlessly into cooling generation to server thermal management, from heat recovery to safety systems.
This comprehensive expertise is based on a full range of technologies: induction, PM synchronous, or reluctance motors; compact, high- power density solutions; air or liquid cooling; protection ratings from IP23 to IP66; and a proven ability to offer custom configurations.
Thanks to the integration of ready-to-use drives and recognized expertise in harmonic management, our motor-drive system guarantees precise control, maximum efficiency (up to IE5 and IES5), and perfect adaptability to complex architectures, from Tier I data centers to Tier IV hyperscale infrastructures.
Key Benefits for Improving PUE and Ensuring Operational Reliability
Leroy-Somer motor & drive solutions are designed to optimize energy efficiency while ensuring flawless operational continuity. Their high reliability, long service life, and ease of maintenance directly contribute to reducing Total Cost of Ownership (TCO), while improving the overall environmental footprint of facilities.
Thanks to their energy efficiency, power density, low noise levels, and high robustness, these technologies offer operators a concrete lever to sustainably improve their PUE and strengthen the resilience of their infrastructure.
Backed by a global presence and an industrial organization scaled for hyperscale projects, these solutions represent a strategic asset for supporting the sector’s rapid evolution and meeting the demands of today’s and tomorrow’s critical environments.
Products for CDU systems and pumping, ventilation, compression, and refrigeration applications in data center
Dyneo+Synchronous Reluctance Permanent Magnet Motors
The “Compact” version of Dyneo+ easily adapts to space constraints and integrates seamlessly into a CDU thanks to its high power factor, which makes it lightweight and compact.
Its ultra-premium IE5+ efficiency optimizes the energy efficiency of a CDU and meets the new PUE standards of 1.2 for current and future generations of data centers.
Maintenance of CDU units equipped with Dyneo+ is easier than that of CDU units equipped with heavier and bulkier induction motors.
Its proven efficiency and performance in pumping and ventilation applications, as well as in air and refrigeration compressors, make it the solution of choice for manufacturers of this type of equipment used in data centers.
A wide range of highly reliable three-phase induction motors, up to IE4, available in cast iron or aluminum, open (IP55/65) or enclosed (IP23) designs, air- or liquid-cooled, with speeds up to 4,500 rpm.
A range of high-power AC drives up to 3.8 MW, modular and ready-to-use, available in cabinet or wall-mounted configurations for high-performance control of AC or PM motors.
