Rival Snapshot — Cloudbit Cooling (air + liquid)
Five cooling shortlist paths for Cloudbit: Vertiv (ABI Leader) for full-stack power+thermal and mature CoolChip CDU (~70–2300 kW) + Liebert air; Johnson Controls (ABI Leader) for campus BMS/OpenBlue + YORK/Silent-Aire air, now with Silent-Aire CDU (Sep 2025 — newer installed base than Vertiv/CoolIT); Schneider + Motivair (ABI Mainstream) when power/racks/EcoStruxure already Schneider (Motivair portfolio Sep 2025); ST

Exec summary
Five cooling shortlist paths for Cloudbit: Vertiv (ABI Leader) for full-stack power+thermal and mature CoolChip CDU (~70–2300 kW) + Liebert air; Johnson Controls (ABI Leader) for campus BMS/OpenBlue + YORK/Silent-Aire air, now with Silent-Aire CDU (Sep 2025 — newer installed base than Vertiv/CoolIT); Schneider + Motivair (ABI Mainstream) when power/racks/EcoStruxure already Schneider (Motivair portfolio Sep 2025); STULZ (Mainstream) for precision CyberAir refreshes plus CyberCool CDU (345–1,380 kW); CoolIT for pure DTC cold-plate → manifold → CDU (pair with a plant/air vendor). Flag 2025 liquid launches (JCI CDU, Schneider Motivair) as newer field maturity vs Vertiv CoolChip / CoolIT.
Comparison
| Vertiv | Johnson Controls | Schneider + Motivair | STULZ | CoolIT | |
|---|---|---|---|---|---|
| Architecture | Liebert PCW/PDX CRAH; DCD RDHx; CoolChip CDU (L2L/L2A); 360AI hybrid refs | YORK CRAH; Silent-Aire CRAH/AHU; M&M Carnot CO₂; Silent-Aire CDU | Uniflair CRAH/CRAC + chillers; Motivair CDUs 105 kW–2.5 MW; ChilledDoor RDHx; HDU L2A | CyberAir 3PRO CW/CW2; CyberRow; CyberRack; CyberCool CDU / CMU hybrid | Rack DLC cold plates + manifolds; CHx L2L; AHx L2A — no hall CRAH |
| Strengths | Full-stack AI densification; CoolChip scale; global service; iCOM/SiteScan | OpenBlue + plant/BMS/campus; Silent-Aire hyperscale air; chip-to-chiller with YORK | EcoStruxure + power/racks adjacency; Motivair HPC/AI liquid heritage | Precision air heritage; dual-circuit CW2; warm-water free-cooling messaging | End-to-end TCS; OEM-agnostic; L2A for brownfield without FWS |
| Typical fit | Hyperscale/colo/enterprise needing power+cooling for AI | Campus/multi-site tied to BMS/fire/security | Already on Schneider stack needing HPC/AI liquid | Enterprise/colo precision air + hybrid DTC add | Pure AI/HPC densification at chip/rack |
| Caveats | Right-size CRAH vs RDHx vs CDU early; CoolChip vs legacy XDU/CoolTera SKU map | ABI-era liquid gap; Silent-Aire CDU Sep 2025 — verify refs & OpenBlue integration | Motivair close Feb 2025 / portfolio Sep 2025 — probe EcoStruxure↔service maturity | Liquid newer vs Vertiv/Motivair MW AI narratives; often partner for cold plates | Not hall/plant/BMS; residual air still needs CRAH; leak/FWS RACI must be explicit |
When to shortlist
| Scenario | Prefer | Often demote |
|---|---|---|
| Traditional air refresh (modest densification) | STULZ CyberAir; Vertiv Liebert; JCI YORK/Silent-Aire; Uniflair if Schneider stack | CoolIT alone |
| Campus DC + BMS / fire / multi-site | JCI (OpenBlue + YORK + Silent-Aire) | DTC specialist as sole vendor |
| AI densification + full-stack power+cooling | Vertiv CoolChip / 360AI; Schneider+Motivair if already Schneider | Vendors without proven in-region CDU+service |
| Brownfield liquid, no facility water | CoolIT AHx; Vertiv CoolChip L2A; Motivair HDU (+ plan CRAH residual) | Assuming L2L without FWS project |
| Pure DTC / GPU rack liquid | CoolIT; Motivair Dynamic plates if Schneider path | Expecting CoolIT to replace chillers/BMS |
| Hybrid hall (DTC + residual air) | Vertiv DCD+CoolChip; STULZ CMU+CyberAir; Schneider ChilledDoor+CDU | Air-only bids ignoring residual % |
| Board pack wants ABI Market Leader label | Vertiv and/or JCI | Calling CoolIT/STULZ ABI Leaders; inventing a Gartner MQ |
Pairings that often work: CoolIT (TCS) + JCI/Vertiv/STULZ (plant/air); Schneider power + Motivair liquid + Uniflair residual; Vertiv power + CoolChip + Liebert residual under 360AI.
Buyer probes
- FWS readiness — temp, flow, ΔT, glycol, filtration; L2L vs L2A required?
- ASHRAE / OEM envelope — thermal class vs inlet / cold-plate supply; W32+ free-cooling feasible?
- CDU redundancy — unit N+1 pumps vs multi-CDU loop; failure behavior; hot-swap
- TCS vs FWS isolation — HX materials, cleanliness (e.g. 25–50 µm claims), fill/drain
- Leak detection RACI — sensors, BMS/DCIM, isolation valves, 24×7 response, secondary damage warranty
- Hybrid residual heat % — PSU/memory/NIC air load; CRAH/RDHx headroom
- Controls — OpenBlue / EcoStruxure / iCOM / STULZ / CoolIT API points + cyber
- Schneider shortlists: Motivair↔EcoStruxure single pane today vs roadmap; joint tickets
- JCI shortlists: Silent-Aire CDU named references, ship dates, multi-unit sync (post ABI liquid gap)
- Cold-plate supply chain — OEM vs CoolIT vs Motivair Dynamic; lead times / revision control
- AI roadmap — next two GPU gens (kW/rack, flow, pressure) without forklift CDU swap
Flags: No DC-cooling Gartner MQ; JCI/Schneider 2025 liquid = newer IB; Uniflair SKUs regional; no invented CoolIT ABI score.
