CoolIT Systems

Calgary-born direct-liquid-cooling specialist — KKR-backed pure-play that Ecolab is buying for $4.75B in March 2026.

1. Core Product / Service

CoolIT Systems designs and manufactures direct-to-chip liquid cooling for high-density compute. The product line:

• Cold plates — the OMNI series, custom-designed for specific GPUs/CPUs (NVIDIA GB200, GB300, H100/H200; AMD MI300X)
• Coolant Distribution Units (CDUs) — rack-level and row-level CDUs that circulate dielectric fluid
• Manifolds and quick-disconnects — the secondary loop infrastructure
• Engineering services — co-design with chip vendors and OEMs (HPE, Dell, Supermicro)

CoolIT was founded in 2001 in Calgary, Alberta. Acquired by KKR in 2024 [3] and now (announced March 19, 2026) being acquired by Ecolab for ~$4.75B in cash, expected to close Q3 2026 [1][2][5]. Status changed from KKR-backed independent to Ecolab subsidiary in motion.

2. Target Users & Pain Points

• Server OEMs — HPE, Dell, Supermicro, Lenovo, Foxconn ship CoolIT cold plates inside their AI servers
• Hyperscalers — large direct deployments of CoolIT CDUs at hyperscale AI campuses
• Chip vendors — NVIDIA + AMD co-design specific cold-plate variants for new SKUs

Pain solved: at >80 kW/rack and at GB200/GB300 NVL72 thermals (~120 kW/rack), air cooling no longer works — direct-to-chip is the only economical option. CoolIT's IP advantage is chip-specific cold plate design — getting thermal pickup right on each new GPU SKU is non-trivial, and CoolIT works on these designs simultaneously with the chip developers, giving it first-mover product advantage on each new generation.

3. Competitive Landscape

CoolIT's edge: NVIDIA Partner Network membership + GB200/GB300 NVL72 design wins + a 20+ year head start over most direct-liquid competitors. The Ecolab acquisition adds water-treatment + chemistry expertise for closed-loop coolant management.

4. Unique Observations

• Ecolab acquisition is the headline (March 19, 2026): $4.75B all-cash, expected close Q3 2026 [1][5]. KKR (acquired CoolIT 2024) flipped in <2 years for what's reported as a strong return — a benchmark for liquid-cooling exit valuations.
• NVIDIA Partner Network: CoolIT joined NVPN with AI-specific DLC products [4]. Cold-plate optimization for NVIDIA GB200, plus a CDU supporting 12 NVIDIA GB300 NVL72 racks at full thermal load — design wins that lock CoolIT into hyperscale AI build BoMs through 2027-2028.
• Why Ecolab paid $4.75B for a cooling company: water/coolant management + chemistry + closed-loop hygiene is the long-tail operational service inside an AI data center. Ecolab's water-treatment expertise + CoolIT's hardware = recurring services revenue (filter changes, coolant replacement, biofilm management) across the installed base. This converts a project-based revenue stream into recurring opex.
• Customer concentration: high (typical for component-level players) — concentrated in OEM channel (HPE, Dell, Supermicro), plus direct hyperscaler deployments. Not publicly disclosed but estimated top-5 customers = 60-70%+ of revenue.
• $/MW share of build cost: liquid cooling adds ~$1-3M/MW vs air-cooled baseline at AI density (~$11-12M/MW vs ~$15M/MW for AI builds). CoolIT captures a slice of this ~$2M/MW DLC layer, as do vertiv, nvent, schneider-electric (Motivair). Total addressable market: 32 GW US under construction × ~$2M/MW = ~$60B over the build cycle, before global geography.
• Depreciation profile: cold plates and CDUs are tied to the GPU refresh cycle — when GPUs swap, cold plates need re-engineering. This is shorter lived than the DC shell (20-30 years) but longer than the GPU itself (4-6 years), because the cooling infrastructure can be partly retrofitted to new chips.
• The liquid cooling battle: 2024-2026 saw four major M&A moves — KKR → Ecolab on CoolIT ($4.75B), Schneider buying Motivair, nvent launching DLC products, and Vertiv investing internally. Liquid cooling has gone from "exotic" to "must-have" in 36 months.

5. Financials / Funding

• Status: KKR-backed (acquired 2024); definitive agreement to be acquired by Ecolab for $4.75B announced March 19, 2026 [1][5]; expected close Q3 2026
• Estimated revenue: not publicly disclosed; industry estimates ~$300-500M/yr range pre-acquisition (implied by deal multiple range)
• Acquisition multiple: $4.75B / estimated $300-500M revenue ≈ 10-15× revenue (premium reflecting strategic scarcity + AI exposure)
• Prior owners: KKR (2024-2026); founder-led + private investors prior

6. People & Relationships

• Founders / Key: Geoff Lyon (founder, CEO through KKR-era); Calgary-based engineering team
• Owner (current): KKR — moving to Ecolab post-close
• NVIDIA Partner Network membership — co-design with NVIDIA on cold-plate IP for new SKUs
• OEM partners: HPE, Dell, Supermicro, Lenovo, Foxconn
• Customer reach: hyperscale AI deployments via OEM channel; direct CDU deployments at major colocation operators
• Strategic future: as an Ecolab subsidiary, CoolIT becomes part of an end-to-end "water + cooling" recurring-services play — the highest-margin permutation of the DLC business model
