nVent Electric

CDUs, manifolds, rear doors, racks and rack PDUs

Published by FyncaResearch checked How we research

Where it fits in an AI server rack

Collaborates with NVIDIA to deploy liquid cooling for GB200 NVL72 and next-generation platforms, having defined a reference architecture that uses nVent’s coolant distribution unit, liquid-to-air heat exchanger and manifold products (nVent release quoting NVIDIA’s Dion Harris). It also sells rear-door heat exchangers (RDHX PRO up to 78 kW), a liquid-to-air sidecar, Enlogic high-density PDUs for AI and server racks, has deployed more than 2 GW of liquid cooling, and is adding a Blaine, Minnesota plant (July 31, 2026).

What the evidence establishes

AI-rack evidence

Disclosed: nVent’s release says it worked with NVIDIA to define a GB200 NVL72 reference architecture using its CDUs, heat exchangers and manifolds, and quotes NVIDIA.

An explicit AI-server or AI-rack product, design-in, supply role, program, reference design or partnership, such as a part named for rack-scale AI systems or a product sold for AI data centers. For a rack builder, it means the company’s own AI servers or racks. This does not establish revenue, market share, volumes or future sourcing.

How we knowDisclosed The company’s own filing, release, annual report, product page or investor record describes the AI-server or AI-rack role. Where customers are unnamed, the listing says so.

Keep in perspective

No customer is named and data-center revenue is not broken out. The $1.75 billion Maverick Power acquisition (data-center switchgear) is pending for Q4 2026, and nVent sold its Thermal Management business to Brookfield in 2025.

Diversified business exposure. This describes the breadth or role of the business; it is not an investment rating. An AI-server product, design-in or partnership does not by itself establish material AI-rack revenue, market share, or future returns.

Connections to the assembly

These links explain the technology relationship. The model is illustrative and does not represent an actual manufacturer’s bill of materials.

Rack PDUs

Power distribution units that bring facility AC into the rack through breakers, with metering so operators can see each feed’s load.

Scope of the company links: Rack PDUs bring facility AC into the rack, with metering and breakers. Schneider updated its NetShelter Rack PDU Advanced for AI servers’ higher currents; Vertiv (Geist), Legrand (Raritan, Server Technology) and Delta (rPDUs) sell rack PDUs for AI and high-density data centers, and Flex lists PDUs in its portfolio. None of these sources names the PDU in a specific NVL72 deployment. Eaton’s rack-PDU line was not verified in our September 2026 review and is not mapped. nVent lists rack PDUs beside its liquid-cooling products.

Rack manifolds

Vertical supply and return pipes at the back of the rack that distribute cool liquid to every tray and collect the warm liquid.

Scope of the company links: Kaori Thermal’s MGX and Vera Rubin rack manifolds are marketed as compliant with NVIDIA’s NVL72 reference designs, and nVent’s manifolds are part of the GB200 NVL72 reference architecture it defined with NVIDIA. Auras (rack, AI and internal manifolds), AVC (manifold systems), Envicool, Delta, Motivair by Schneider Electric (in-rack manifolds), CoolIT (Ecolab), JetCool (Flex), Nidec (coolant distribution manifolds) and Forcecon (catalog) also document manifolds. NVIDIA’s GB200 NVL72 design uses a blind-mate liquid-cooling manifold (NVIDIA, Oct 2024); which supplier builds it for a given rack is not disclosed. Eaton (Boyd Thermal), Supermicro and Luxshare also list rack manifolds for liquid-cooled AI racks.

Coolant distribution unit

Pumps, a heat exchanger, filters and controls that circulate the rack’s clean coolant and pass its heat to the building’s water loop.

Scope of the company links: In-rack CDUs like the illustrated one sit at the bottom of the rack: Kaori (4U in-rack CDU), Auras, SUNON (in-rack RPU/CDU, mass-production ready in 1H 2026), JetCool (Flex; SmartSense rack-mounted CDU), Envicool (rack CDU validated by Intel) and Forcecon (80 kW, catalog). Row- and facility-scale CDUs serve many racks: nVent (in its GB200 NVL72 reference architecture with NVIDIA), Delta (40–144 kW liquid-to-air; 1.5 MW liquid-to-liquid), Motivair by Schneider Electric (MCDU-70 in the Schneider–AMD Helios reference design; WCDU up to 3.5 MW), CoolIT (Ecolab), Vertiv (Liebert XDU), AVC, Nidec, Modine’s Airedale (400 kW–2 MW+) and Lite-On (a 600 kW in-row CDU announced in 2024). Sanyo Denki supplies a liquid-cooling pump, a CDU component rather than a CDU. LiquidStack is private. Eaton’s Boyd Thermal markets CDUs for GB200 NVL72 deployments, Supermicro’s GB300 NVL72 rack carries its own in-rack CDU of up to 250 kW, and Luxshare lists CDUs.

Rear-door heat exchanger

A door on the back of the rack with a liquid coil that captures the heat left in the exhaust air before it reaches the room.

Scope of the company links: Motivair by Schneider Electric’s ChilledDoor rear-door heat exchangers handle the air-cooled share in the Schneider–AMD Helios reference design (July 2026); nVent sells rear-door heat exchangers (RDHX PRO up to 78 kW); Delta lists a 50 kW rear-door heat exchanger; Vertiv sells Liebert DCD rear doors (up to 50 kW); Kaori Thermal sells RDHx units. A rear door is optional in NVL72-class deployments, and which racks use one is not disclosed. Supermicro sells a 120 kW rear-door heat exchanger, Dell a PowerCool enclosed rear-door heat exchanger, and Legrand the USystems ColdLogik rear doors.

Rack frame & panels

A reinforced steel frame of posts, cross members and panels sized for wide trays, a rear busbar and manifolds. The compute and switch trays alone weigh roughly 675 kg in NVL72-class designs.

Scope of the company links: Schneider Electric launched a rack system for NVIDIA GB200 NVL72 on the MGX architecture (June 2025), and Delta and Lite-On show racks for NVIDIA MGX. Vertiv says the three-rack configuration it deployed for the Naval Postgraduate School’s NVIDIA DGX GB300 included ‘AI infrastructure racks’ with power and liquid cooling (July 23, 2026), without saying whether they house the GB300 itself. Dell sells its own ORv3 21-inch IR7000 rack with its GB300 NVL72 systems; the fabricator is not disclosed. Legrand sells OCP racks with an ORv3 busbar, nVent lists server racks (AI-rack use not established) and AVC lists server cabinets. The MGX-rack makers Rittal (MGX Architecture Rack for GB200/GB300 NVL72, Oct 14, 2025) and Cheval (ORv3 MGX rack for GB200 NVL72) are private. Supermicro, Lenovo and Chenbro ship complete racks without naming the frame maker.
