Legrand is expanding its data center footprint with the acquisition of Colorado-based Kratos Industries and a strategic investment in Accelsius, a developer of two-phase, direct-to-chip liquid cooling systems. The moves strengthen Legrand’s end-to-end power and thermal management portfolio as AI-driven workloads push rack densities and infrastructure requirements higher.
Kratos Industries manufactures low-voltage switchboards, medium-voltage switchgear, and integrated power systems used in data center gray space and industrial environments. The Arvada, Colorado-based company operates a vertically integrated, engineered-to-order production model tailored for mission-critical deployments. By adding Kratos, Legrand broadens its critical power portfolio across the full data center power train, extending its gray space offerings such as cable bus, load banks, and cable tray, while complementing its white space solutions including busway, busduct, and rack power distribution units (PDUs).
In parallel, Legrand participated in Accelsius’ Series B funding round, advancing its position in high-density liquid cooling architectures. Accelsius develops two-phase direct-to-chip cooling systems designed to extract heat at the processor level, supporting higher compute densities while lowering energy consumption for thermal management. The companies plan joint development initiatives to integrate liquid cooling into rack-level white space infrastructure, targeting AI factories and other high-performance compute environments.

🌐 Analysis
Legrand’s dual move reflects a broader industry shift toward vertically integrated power and thermal stacks as AI clusters drive higher rack densities and tighter coupling between electrical and cooling systems. Competitors across the data center ecosystem — including rack OEMs, switchgear vendors, and liquid cooling specialists — are forming similar alliances to address the convergence of gray space power distribution and white space thermal design in next-generation AI facilities.
Legrand is a France-based global provider of electrical and digital building infrastructure solutions serving residential, commercial, industrial, and data center markets. The company offers a broad portfolio spanning power distribution, wiring devices, structured cabling, busway, rack power distribution units (PDUs), and digital infrastructure systems. Legrand has expanded its data center footprint through a steady cadence of acquisitions and product development, positioning its Data, Power, and Control (DPC) division to address both gray space and white space requirements. In 2025, Legrand reported €9.5 billion in revenue and maintained listings on Euronext Paris, including membership in the CAC 40 index.
