Datacenter Cooling — Market

Verified claims and product-axis read for Datacenter Cooling. Every fact below is sourced; every product judgment traces back to underlying signals.

Verified facts

• CoolIT, Asetek, and Vertiv are simultaneously named in NVIDIA GB200 NVL72 deployment ecosystems. ↗ (other)
• At least three vendors (nVent, Modine, CoolIT) posted CDU-specific mechanical-design engineering roles between February and April 2026. ↗ (other)
• Vertiv, CoolIT, Asetek, Iceotope, nVent, Modine, and Munters together form the in-sample competitive set for datacenter liquid cooling. ↗ (other)
• Munters' DCT segment growth being tied to hyperscaler AI capex creates a ~45%-of-revenue concentration risk. ↗ (financial)

Direct-to-Chip Liquid Cooling CDU — rack/row CDU + cold-plate loop

Opportunity: NVIDIA GB200 NVL72 reference architecture plus incremental GB300 CDU pull (verified facts b8a6220a, 29788d0f) push every >100kW AI rack toward D2C loops; OEMs (Dell/Supermicro/HPE) and neoclouds (CoreWeave/OpenAI) need certified CDU + cold-plate vendors that can ship volume.

Most crowded and most validated lane in the topic — Asetek, CoolIT, and nVent are all hiring D2C-specific engineering & sales while booking design wins at every tier (OEM SKU, neocloud, hyperscaler). Differentiation has shifted from 'can you build it' to manufacturing scale-up and field reliability.

Indirect/Direct Evaporative Cooling Air Handling Unit — evaporative + hybrid liquid-assisted AHU

Opportunity: Munters DCT is ~SEK 7B / ~45% of group and posting double-digit growth (verified facts c4e4b8b3, 97416002), but the water-use scrutiny in HN discussion (cbr_post 8731af50) raises political/permitting risk that pushes the roadmap toward 'hybrid liquid-assisted' — the exact phrase in the PM job spec.

Confirmed hot at the revenue level — multiple Munters earnings calls flag DCT as the primary growth engine, and the May 2026 Product Manager req signals an explicit roadmap pivot to hybrid liquid-assist. Real downside risk is water-use narrative tightening hyperscale evaporative permitting.

Schroff Liquid Cooling Enclosure and Rack Manifold — rack enclosure + secondary manifold

Opportunity: AI rack TDP scaling forces a parallel BoM line for the chassis-side plumbing (enclosure + secondary manifold) so a hyperscaler can mix-and-match D2C / RDHx CDUs without redesigning the rack (verified fact 2c15f174).

nVent Schroff is the visible 'pick-and-shovel' specialist: production scale-up role + Sr engineering role + Q4 2025 customer-win. Caveat: no demand_query specifically asks 'rack manifold', so demand-side pull is inferred from the broader liquid-cooling search bundle.

KU:L Precision Liquid Cooling Chassis — chassis-level precision liquid cooling

Opportunity: Customers needing >100kW/rack at HPC plus AI workloads (verified facts 23a78dc2, a5564d64: qualified at 10+ HPC/AI customers as of Jan 2026) and not wanting full tank immersion get a 'precision liquid' middle path.

Single-vendor lane (Iceotope), but already qualified at 10+ HPC+AI customers — a credible alternative to both tank immersion and D2C cold plates. Watch for second-source / OEM partnership; that's what would break it out beyond Iceotope direct.
