Leading manufacturers of Cold Aisle Data Center PDUs include Eaton, Rittal, Supermicro, Legrand, and ACT, offering modular, high-density, and energy-efficient solutions for server racks.

Eaton

Eaton provides a wide range of rack-mounted PDUs suitable for cold aisle environments, from basic to advanced switched PDUs. Their ePDU G4 technology supports High Density (HD) Metered and Managed PDUs, as well as Universal Input PDUs (UPDU). Features include tool-less installation, color-coded outlets, remote monitoring, outlet-level switching, and daisy-chaining up to eight PDUs under a single IP address, making them ideal for both small network closets and enterprise data centers .

Rittal

Rittal offers modular PDUs designed for zero-U installation in server racks, which integrate seamlessly with aisle containment systems. Their solutions focus on energy efficiency and climate control optimization, ensuring consistent separation of hot and cold air in the data center .

Supermicro

Supermicro's Data Center Building Block Solutions (DCBBS) include 33kW Power Shelves and Battery Backup Units for 48V DC power, integrated with in-rack Coolant Distribution Units (CDUs) and rear door heat exchangers. These PDUs are optimized for high-density AI and HPC racks, supporting liquid cooling, scalable multi-rack deployments, and turnkey integration with networking and thermal management .

Legrand

Legrand specializes in cold aisle containment systems that work in conjunction with PDUs to direct cold air to server inlets, improving cooling efficiency and reducing energy consumption. Their Contain-IT FLEX system is modular, pre-fabricated, and scalable, allowing flexible deployment and reconfiguration for evolving data center layouts .

ACT (Advanced Cooling Technologies)

ACT manufactures Coolant Distribution Units (CDUs) for direct-to-chip liquid cooling, including Two-Phase in-rack CDUs for high-density server racks. These units provide precise thermal management, uniform chip temperatures, and energy-efficient cooling, suitable for edge, storage, telecom, and hyperscale environments .

Summary

For new cold aisle DC PDUs, these manufacturers provide solutions that combine high-density power distribution, modularity, monitoring, and integration with advanced cooling systems. Selection depends on your data center's rack density, cooling strategy, and monitoring requirements, with options ranging from basic PDUs to fully managed, high-density, liquid-cooled systems.
