Manufacturers of NEMA4X Cold Aisle Power Supply Equipment

Key manufacturers of NEMA 4X-rated enclosures and cooling solutions for cold aisle power supply equipment include NEMACO, Vililong, Vortex Air, Legrand, and Nema Enclosures.

NEMACO

NEMACO™ produces NEMA 4X enclosures constructed from 304 or 316 stainless steel with ASTM A967 passivation, offering superior resistance to corrosion, chemicals, and harsh environments. Their enclosures protect electrical and control equipment from dust, rain, splashing water, and high-pressure hose-directed water. Optional closed-loop A/C units or filtered fan systems can be integrated, with thermal calculations available to match ambient temperature and heat load requirements .

Vililong

Vililong manufactures industrial-grade NEMA 4X stainless steel enclosures designed for extreme conditions, including marine, chemical processing, food and beverage, and pharmaceutical applications. They offer custom width, height, and depth, with powder-coated or stainless steel finishes. Their process includes consultation, technical evaluation, prototyping, and mass production, ensuring enclosures meet specific environmental and operational requirements .

Vortex Air

Vortex Air provides NEMA 4X-rated enclosure coolers that maintain precise temperature control for electrical and electronic equipment. Their vortex coolers use filtered compressed air and vortex tube technology to protect sensitive components from heat and contamination. Cooling capacities range from 400 BTU/hr to 5000 BTU/hr, and units can be thermostatically controlled or constant-run, making them suitable for cold aisle power supply applications .

Legrand

Legrand offers cold aisle containment solutions that integrate with NEMA-rated cabinets. Their T-Series and T6 cabinet platforms are engineered for data center environments, providing modular, scalable, and pre-configured solutions that enhance cooling efficiency and equipment reliability. These cabinets can be paired with containment systems to optimize airflow and maintain consistent temperatures in cold aisles .

Nema Enclosures

Nema Enclosures specializes in custom and standard NEMA 4X electrical enclosures for outdoor and harsh environments. They provide options for silk-screening, passivation, and electro-polishing, ensuring corrosion resistance and compliance with rigorous NEMA standards. Their enclosures are suitable for protecting power supply equipment in cold aisle setups . These manufacturers collectively offer a range of NEMA 4X enclosures and cooling solutions suitable for cold aisle power supply applications, with options for customization, thermal management, and compliance with industrial standards.
