Data Center Coolant Distribution Units Market Size, Share & Forecast to 2035

The Data Center Coolant Distribution Units Market is valued at USD 2.08 billion in 2026 and is projected to reach USD 5.46 billion by 2035, up from USD 1.46 billion in 2025, a CAGR of 14.07% from 2025 to 2035 (DC Market Insights estimate). What moves the money is the rack, not the building: NVIDIA’s GB200 NVL72 places 72 graphics processing units (GPUs) in one liquid-cooled rack drawing about 120 kW, so every such rack needs a coolant distribution unit (CDU) to hold its secondary loop at a set temperature, pressure and flow. DC Market Insights counts 3,920 MW of new IT load placed on CDU-served loops in 2025, 32.70% of the 12.0 GW built worldwide, and prices the CDU at about USD 285 per kW of that load, which gives USD 1.12 billion of new-build spend before retrofits and service. The unit itself is growing faster than the load it serves: Vertiv’s CoolChip CDU 2300 handles 2.3 MW in one cabinet and Google’s Project Deschutes specification sets a 2 MW reference unit, so facility-scale CDUs above 1 MW grow at 21.84% a year, while the Middle East and Africa is the fastest region at 18.42%.

How Big Is the Coolant Distribution Unit Market in 2026, and How Fast Is It Growing?

DC Market Insights values CDU spend at USD 2.08 billion in 2026, 41.90% above the USD 1.46 billion of 2025, as 5,840 MW of new liquid-cooled IT load comes on line.

• Market size 2025: USD 1.46 billion (DC Market Insights estimate).
• Market size 2026: USD 2.08 billion.
• Market size 2030: USD 3.99 billion.
• Market size 2035: USD 5.46 billion.
• CAGR 2025-2035: 14.07% base case; 10.69% low case and 16.26% high case.
• Largest product type: liquid-to-liquid CDUs, 66.00% of 2025 value.
• Fastest segment: CDUs above 1 MW, 21.84% a year to 2035.
• Leading region: North America, 47.00% of 2025 value; fastest region: Middle East and Africa at 18.42%.
• Largest country: United States, USD 623.05 million in 2025.
• Market leader: Vertiv, followed by Schneider Electric (Motivair), with an estimated 58% of 2025 value held by the five largest suppliers.

Key Takeaways: What Should CDU Buyers Note From the 2026 Numbers?

• 30.00% of 2025 CDU value already sat in units above 1 MW, and that share reaches 58.00% by 2035 because one facility unit replaces eight to fifteen in-row units on an AI hall.
• USD 285 per kW in 2025 falls to USD 190 per kW by 2035 in the base case, because larger frames spread pumps, heat exchangers and controls over more load.
• USD 1.90 billion of 2035 spend is service, fluid and filtration on the installed base, up from USD 171.19 million in 2025, so recurring revenue overtakes retrofits within the forecast.

What Did the CDU Market Earn From 2020 to 2025, and Where Does It Go by 2035?

The Global Data Center Coolant Distribution Units Market size was valued at USD 198.52 million in 2020, reached USD 1.46 billion in 2025, and is anticipated to reach USD 5.46 billion by 2035, at a CAGR of 14.07% during the forecast period. The 2020-2025 CAGR of 49.14% reflects a market that was mostly high-performance computing (HPC) and test halls until 2023 and then moved into volume with AI racks.

Attribute	Detail
Historical period	2020-2024
Base year	2025
Forecast period	2026-2035
Market size 2025	USD 1.46 billion
Market size 2026	USD 2.08 billion

Market size 2035	USD 5.46 billion
Segments covered	Product Type, Cooling Capacity, Form Factor, End User
Regions covered	North America, Europe, Asia Pacific, Latin America, Middle East and Africa

DC Market Insights estimates that growth slows from 41.90% in 2026 to single digits after 2031, because the liquid share of new IT capacity flattens near 64.00% and the price per kW keeps falling; volume in MW still more than quadruples, from 3,920 MW in 2025 to 17,280 MW a year in 2035.

What Counts as a Coolant Distribution Unit in This Estimate?

USD 1.46 billion of 2025 spend covers the CDU itself: a cabinet or skid with pumps, a heat exchanger, filters, valves, sensors and controls that separates the technology cooling system (TCS), the loop that runs through cold plates or rear doors, from the facility water system (FWS) or from room air.

Included: liquid-to-liquid CDUs, liquid-to-air CDUs (sidecar units that reject heat to the hall air), hybrid and two-phase units, in-rack, in-row and facility-scale formats, commissioning, coolant fill, filtration and service contracts. Excluded: cold plates, manifolds and secondary fluid network piping, which sit in the Data Center Piping Market; leak sensors, which sit in the Data Center Leak Detection Market; chillers, dry coolers and other refrigeration equipment on the facility side; and immersion tanks. Pumps are counted inside the CDU value here; the Data Center Cooling CDU Pumps Market sizes the pump component on its own at USD 299.87 million in 2025, about 20% of CDU value, from the same 3,920 MW of new CDU-served capacity.

How the segments fit together: every split below sums to the total in every year. The Data Center Liquid Cooling Market is the parent scope: CDUs take about 25% of its USD 5.80 billion 2025 value and about 20% of its USD 27.40 billion 2035 value, because cold plates and fluid networks grow faster than the units that feed them.

Why Do Coolant Distribution Unit Market Estimates Differ?

Estimates differ mainly on the boundary: DC Market Insights puts the 2026 market at USD 2.08 billion, and broader definitions that add the fluid network, cold plates, cooling capacity on the facility side or end use in industrial process cooling report larger totals.

A wider count usually adds three things. First, the secondary fluid network and row manifolds that Vertiv now sells alongside its CDUs; DC Market Insights places those in its piping estimate. Second, facility refrigeration equipment such as chillers, which a CDU connects to but does not contain. Third, server-level parts from makers such as Super Micro Computer, whose racks ship with in-rack CDUs already fitted; DC Market Insights counts only the CDU share of such racks, inside the in-rack segment. Small and medium-sized enterprises (SMEs) and edge sites are in scope as buyers of in-rack and liquid-to-air units.

Element	In this estimate	Why
CDU cabinet or skid (pumps, heat exchanger, controls)	Yes, USD 1.29 billion in 2025	Core product
Commissioning, coolant, filtration, service	Yes, USD 171.19 million in 2025	Bought with or for the CDU
Secondary fluid network, manifolds, cold plates	No	Sized in piping and liquid cooling reports
Chillers, dry coolers, cooling towers	No	Facility water side
Immersion tanks	No	Different heat path; tank-integrated pumps
Industrial process CDUs outside data centers	No	Not a data center end use

Why Is Demand for Coolant Distribution Units Rising So Fast?

Demand rises because liquid-cooled IT load placed on CDUs grows from 3,920 MW in 2025 to 5,840 MW in 2026, a 48.98% jump, by DC Market Insights estimates.

GB200 and GB300 Racks at About 120 kW Cannot Be Air-Cooled

According to NVIDIA’s GB200 NVL72 product page, the GB200 NVL72 joins 72 Blackwell GPUs and 36 Grace central processing units (CPUs) in one liquid-cooled rack. At about 120 kW per rack, against 10-15 kW for a conventional air-cooled rack, the only practical heat path is cold plates fed by a CDU. DC Market Insights estimates that each MW of such racks needs USD 0.285 million of CDU capacity at 2025 prices, and that AI racks drove 52.00% of 2025 CDU spend through hyperscale and AI cloud buyers.

Vertiv Orders Up 252% Show the Pipeline Behind 2026 Shipments

Vertiv reported organic orders growth of 252% for the fourth quarter of 2025 in its fourth-quarter 2025 results filed with the U.S. Securities and Exchange Commission (SEC), and its second-quarter 2026 release put net sales at USD 3.27 billion, up 24%, with 2026 guidance of USD 13.8-14.2 billion (Source: Vertiv). Thermal management, including CDUs, is a large part of that backlog. DC Market Insights uses the order surge as the reason 2026 CDU spend grows 41.90% while new IT capacity grows about 22%.

Brownfield Halls Retrofit With Liquid-to-Air Units

DC Market Insights estimates that 420 MW of existing air-cooled halls added CDUs in 2025, worth USD 176.40 million, rising to 820 MW a year by 2030. Liquid-to-air CDUs let an operator run cold-plate racks without a facility water loop; Vertiv’s November 2024 launch paired the 2.3 MW liquid-to-liquid unit with a 350 kW liquid-to-air unit for this use, according to the Vertiv investor release of 19 November 2024.

How Is CDU Design Changing as Units Pass 2 MW?

The main change is scale: units above 1 MW take 30.00% of 2025 value and 58.00% by 2035, by DC Market Insights estimates.

Google Project Deschutes Sets an Open 2 MW Reference

Google led an Open Compute Project (OCP) effort that published Project Deschutes, a 2 MW CDU specification with design files, so that several suppliers can build interchangeable units. Boyd showed a Deschutes-compliant unit at the October 2025 OCP Global Summit, and Nidec Corporation exhibited its own prototype to the Google OCP specification at SC25 in November 2025 (Source: Boyd; Nidec). A shared reference lowers the engineering cost per unit and helps explain why DC Market Insights models the price per kW falling 3% to 5% a year.

Power and HVAC Groups Buy CDU Makers

Four deals in 28 months moved CDU know-how into larger groups: Vertiv closed its purchase of CoolTera on 8 December 2023 (Source: Vertiv Form 10-K); Schneider Electric completed its 75% stake in Motivair on 28 February 2025, with the remaining 25% expected in 2028 (Source: Schneider Electric); Trane Technologies agreed to buy LiquidStack on 9 February 2026 (Source: Trane Technologies); and Eaton completed its purchase of Boyd Thermal on 12 March 2026 (Source: Eaton). Buyers now order the CDU with the switchgear or the chiller plant, which favours suppliers that can quote both.

Warmer Facility Water Shrinks the Chiller Plant

CDUs rated for warm facility water let operators drop compressor hours. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) liquid cooling classes run from W17 to W45 and W+ (facility water up to 45°C and above), and DC Market Insights estimates that 64% of 2025 liquid-to-liquid CDU MW was specified at W32 or warmer. Johnson Controls and Schneider Electric France both sell CDUs matched to their own chiller lines for this reason.

What Holds Back Coolant Distribution Unit Sales?

Two limits stand out: coolant quality and supply lead times, which DC Market Insights estimates cost the market about USD 124.72 million of 2026 shipments that slip into 2027.

Coolant Chemistry and Filtration Failures

Cold plates have micro-channels near 100 microns wide; particles or biological growth in the secondary loop raise pressure drop and can starve a GPU of flow. Project Deschutes specifies 0.2-micron side-stream filtration for this reason (Source: Boyd). DC Market Insights estimates that filters, fluid testing and coolant replacement add 3% to 4% a year to the installed CDU value, and that an operator without a fluid-management contract faces higher failure rates.

Lead Times of 20 to 30 Weeks for Large Units

Large CDUs share heat exchangers, variable-speed pumps and controls with chiller and district-energy plants. DC Market Insights estimates lead times of 20 to 30 weeks for units above 1 MW in 2025 and 2026, and models 6% of 2026 demand slipping a year, worth about USD 124.72 million.

Where Are the Largest New Revenue Pools for CDU Suppliers?

The two largest pools are facility-scale units for AI campuses, worth USD 3.33 billion by 2035, and service on the installed base, worth USD 1.90 billion by 2035.

Facility-Scale Units for AI Campuses

Facility-scale CDUs grow from USD 556.62 million in 2025 to USD 3.33 billion in 2035, a CAGR of 19.60%. A 100 MW AI campus at 2026 prices needs about USD 27.3 million of CDU capacity, and suppliers that can deliver 2 MW skids pre-tested in the factory win on site labour.

Service, Fluid and Filtration Contracts

Service and fluids rise from USD 171.19 million in 2025 to USD 1.90 billion in 2035 as the installed CDU base ages; DC Market Insights models service at 5.50% of the eight-year installed equipment value in 2025, rising to 7.5% by 2035 as contracts add remote monitoring.

How Much Does a Coolant Distribution Unit Cost per kW?

A new-build CDU costs about USD 285 per kW of IT load in 2025, falling to USD 190 per kW by 2035, by DC Market Insights estimates; retrofit units cost more, about USD 420 per kW in 2025.

Year	New-build CDU (USD per kW)	Retrofit CDU (USD per kW)	Liquid-cooled IT load on CDUs (MW)
2020	310	450	300
2025	285	420	3,920
2030	225	350	12,210
2035	190	300	17,280

At USD 285 per kW, a 2.3 MW facility unit carries about USD 0.66 million of value including controls and commissioning, and a 100 kW in-rack unit about USD 0.05 million. The price ladder steps down with size: in-rack units cost about 1.6 times the per-kW price of facility units.

Which Rules and Standards Shape CDU Specifications?

Three sets of rules matter, and the EU one applies to every site of 500 kW or more of installed IT power demand.

• European Union (EU): Commission Delegated Regulation (EU) 2024/1364 requires operators of data centres of 500 kW or more to report energy and water key performance indicators (KPIs) to a European database each year; a draft Commission amendment of 26 March 2026 moves toward rating labels based on power usage effectiveness (PUE) and water usage effectiveness (WUE) (Source: European Commission). CDUs that allow warm-water cooling lower both.
• ASHRAE TC 9.9 liquid cooling guidelines: facility water classes W17 to W45 and W+ set the supply temperatures a CDU must accept (Source: ASHRAE).
• Open Compute Project: the Project Deschutes 2 MW CDU specification and the OCP Advanced Cooling Solutions work define interfaces, filtration and redundancy (Source: Open Compute Project).
• Germany Energy Efficiency Act (EnEfG): a PUE limit of 1.2 for new data centres opening from 1 July 2026 favours liquid cooling with CDUs over air (Source: German Federal Ministry for Economic Affairs and Climate Action).

Which CDU Types and Sizes Carry the Most Value?

Liquid-to-liquid CDUs carry 66.00% of 2025 value, and units above 1 MW are the fastest-growing size band at 21.84% a year, by DC Market Insights estimates.

By Product Type

Liquid-to-liquid units lead because new AI halls are built with a facility water loop. Liquid-to-air CDUs grow only 6.43% a year as they stay a retrofit tool; hybrid and two-phase units grow fastest at 20.05% from a small base.

Product Type	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Liquid-to-Liquid CDUs	966.77	66.00%	4,152.21	15.69%
Liquid-to-Air CDUs	410.14	28.00%	764.88	6.43%
Hybrid and Two-Phase CDUs	87.89	6.00%	546.34	20.05%

By Cooling Capacity

Units above 1 MW rise from USD 439.44 million to USD 3.17 billion; units up to 150 kW grow 5.42% a year as in-rack designs lose share.

Cooling Capacity	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Up to 150 kW	322.26	22.00%	546.34	5.42%
150 kW to 1 MW	703.10	48.00%	1,748.30	9.54%
Above 1 MW	439.44	30.00%	3,168.79	21.84%

By Form Factor

Facility-scale CDUs overtake in-row units in 2027 by DC Market Insights estimates and reach 61.00% of value in 2035.

Form Factor	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
In-Rack CDUs	263.66	18.00%	491.71	6.43%
In-Row CDUs	644.51	44.00%	1,639.03	9.78%
Facility-Scale CDUs	556.62	38.00%	3,332.69	19.60%

By End User

Hyperscale and AI cloud operators buy 52.00% of 2025 value; colocation providers grow fastest at 15.71% because they fit liquid-ready halls for AI tenants.

End User	2025 (USD million)	Share 2025	2035 (USD million)	CAGR 2025-2035
Hyperscale and AI Cloud Operators	761.70	52.00%	3,004.89	14.71%
Colocation Providers	380.85	26.00%	1,639.03	15.71%
HPC and Research Centers	161.13	11.00%	273.17	5.42%
Enterprise and Edge Data Centers	161.13	11.00%	546.34	12.99%

DC Exclusive: The CDU Supplier Ownership Map, Seven Makers and Four Takeovers

This DC Market Insights supplier map is built from 11 inputs: 7 dated company filings and releases and the 4-dimension market model. It shows that four of the seven suppliers below changed owner or bought a CDU maker between December 2023 and March 2026, and that DC Market Insights estimates the five largest suppliers held about 58% of the USD 1.46 billion of 2025 value.

Supplier	Ownership or deal	Largest unit class	Main format
Vertiv	Vertiv (CoolTera, closed 8 Dec 2023)	2.3 MW (CoolChip CDU 2300)	Facility and in-row
Schneider Electric	Motivair, 75% stake closed 28 Feb 2025	Facility and in-row	Liquid-to-liquid
Eaton	Boyd Thermal, closed 12 Mar 2026	2 MW class (Deschutes-compliant)	Facility
Trane Technologies	LiquidStack, agreed 9 Feb 2026	Facility	Liquid-to-liquid and two-phase
nVent	Own range	In-row and in-rack	Liquid-to-liquid and liquid-to-air
Nidec	Own range	2 MW prototype (SC25, Nov 2025)	Facility
CoolIT Systems	Independent	In-row and in-rack	Liquid-to-liquid

The map matters to a buyer because the CDU is now sold as part of a power or chiller package: three of the four acquirers also make switchgear, uninterruptible power supplies or chillers. Buyers who tender the CDU alone still get the widest field of independents, such as CoolIT Systems, Envicool, STULZ, FläktGroup and DCX Liquid Cooling Systems, which launched an 8 MW facility CDU for warm-water AI halls in January 2026 (Source: DCX Liquid Cooling Systems).

Which Regions Buy the Most Coolant Distribution Units?

How the Model Sizes the CDU Market

DC Market Insights built the estimate bottom-up from 3 volume inputs and 3 price inputs for each of 16 years. New IT capacity (12.0 GW in 2025, 22 GW in 2030, 27 GW in 2035) times the share placed on CDU-served liquid loops (32.70% in 2025, 64.00% in 2035) gives 3,920 MW in 2025; times USD 285 per kW gives USD 1.12 billion. Retrofits add 420 MW at USD 420 per kW, USD 176.40 million, and service adds USD 171.19 million. Three bound checks:

• Ceiling 1: CDU value is 25% of the USD 5.80 billion 2025 liquid cooling market, within a 15% to 30% band for the CDU share of a direct liquid cooling system.
• Ceiling 2: 3,920 MW on CDUs is 32.70% of 2025 new IT capacity, below the 35% AI share, since not every AI rack is liquid-cooled.
• Floor: 3,920 MW at a minimum of USD 150 per kW gives USD 588 million, below the USD 1.12 billion new-build estimate.
