Thailand Data Center Cooling Market Size, Share & Forecast to 2035

The Thailand Data Center Cooling Market is valued at USD 446.25 million in 2026 and is projected to reach USD 1.66 billion by 2035, up from USD 237.12 million in 2025, a CAGR of 21.47% from 2025 to 2035 (DC Market Insights estimate). Water, more than electricity, now decides how Thai data halls are cooled: Bridge Data Centres signed a 10-year contract with Eastwater Stecon Utilities in October 2025 for up to 3.3 million cubic metres a year for a roughly 200 MW Chonburi campus, which DC Market Insights reads as about 16,500 cubic metres per megawatt a year if the halls ran fully evaporative. That ratio, set against a Board of Investment (BOI) rule that its high-efficiency tier keeps power usage effectiveness (PUE) at or below 1.3, pushes buyers in the Eastern Economic Corridor (EEC) toward hybrid towers, dry coolers and direct liquid cooling rather than open cooling towers alone. The money therefore follows megawatts: DC Market Insights books 132.5 MW of 2025 IT capacity at a blended USD 1.57 million of cooling per MW (USD 208.02 million of new-build cooling) and adds USD 29.10 million of service and retrofit on the installed base.

The Thailand Data Center Cooling Market covers the equipment, installation and service that remove heat from Thai data halls: chillers and heat rejection, air-side precision cooling, liquid cooling, and cooling controls. Liquid Cooling is the fastest-growing technology at 37.29% a year as AI halls move past 40 kW per rack, and the Eastern Economic Corridor is the fastest-growing region at 27.84% a year because the largest new campuses sit in Chonburi, Rayong and Chachoengsao.

How Fast Is Thai Data Center Cooling Spend Growing from 2020 to 2035?

The Thailand Data Center Cooling Market size was valued at USD 51.35 million in 2020, reached USD 237.12 million in 2025, and is anticipated to reach USD 1.66 billion by 2035, at a CAGR of 21.47% during the forecast period.

Historical period	2020-2024
Base year	2025
Forecast period	2026-2035
Market size 2025	USD 237.12 million
Market size 2026	USD 446.25 million
CAGR 2025-2035	21.47%
Market size 2035	USD 1.66 billion

Spend grew 35.80% a year from 2020 to 2025 as Thai completions rose from 30 MW to 95 MW, and it nearly doubles in 2026 because cooling is ordered the year before a hall energises. DC Market Insights books 380 MW of cooling orders in 2027 against 330 MW of completions and 465 MW in 2028, so 2027 spend reaches USD 699.50 million. After 2030 the curve flattens to 8.57% a year: completions settle near 500-600 MW and the service line, USD 463.89 million by 2035, does more of the work. The Board of Investment recorded 36 data center projects worth over USD 23.1 billion of applications in 2025 (BOI 2025 investment statement), which is the order book behind this cooling ramp.

Key Takeaways: What Should Buyers of Thai Data Center Cooling Know?

Four findings explain why Thai cooling spend grows 21.47% a year to 2035.

• Water caps, not chiller prices, set EEC designs: an open-tower campus needs about 16,500 cubic metres per MW a year, so hybrid systems that use 35% of that water win water-capped sites.
• Liquid Cooling grows 37.29% a year because AI halls cost USD 1.95 million of cooling per MW against USD 1.45 million for conventional halls and need direct-to-chip loops.
• The Eastern Economic Corridor overtakes Bangkok around 2032 because the six tracked EEC campuses alone carry 1,150 MW of announced capacity.
• Service and retrofit rise to 28.0% of spend by 2035 because installed Thai IT load grows elevenfold to 4,917 MW.

What Does Thailand Data Center Cooling Include, and Where Does It Stop?

The Thailand Data Center Cooling Market covers USD 237.12 million of 2025 spend on cooling equipment, installation and upkeep sold to data centers located in Thailand.

Included

Chillers (centrifugal, screw and air-cooled), cooling towers, hybrid and adiabatic coolers and dry coolers; computer room air handlers (CRAH), precision air conditioners, in-row units, fan walls and rear-door heat exchangers; direct-to-chip liquid cooling hardware such as coolant distribution units (CDUs) and facility-side loops, plus immersion tanks; building management and cooling controls software; design, installation and commissioning; maintenance, refrigerant service and retrofits of operating halls.

Excluded

The electricity used by cooling (a Thai cooling plant at PUE 1.3 still buys power at the Energy Regulatory Commission (ERC) charge of THB 3.95 per unit for May-August 2026), raw and treated water purchases, server fans and cold plates shipped inside servers, comfort air-conditioning in offices, and power equipment. Total data center capital spend sits in the Thailand Data Center Market (USD 1.95 billion in 2025); cooling is 12.2% of that total.

How the segments fit together

Every dimension below sums to the market total each year: four cooling technologies, three offerings, four data center types, five Thai regions and twelve provinces.

Why Do Thailand Data Center Cooling Market Estimates Differ?

Published figures for Thai data center cooling range widely because definitions differ, while DC Market Insights puts the 2026 market at USD 446.25 million on a strict cooling-hardware-and-service scope.

Broader definitions add the electricity that cooling consumes (at PUE 1.3, cooling and other overhead use up to 23% of a campus’s power), the water bill, comfort cooling in the whole building, and server-side fans and cold plates bought with the IT. Narrower ones count only new-build equipment and drop service, which in this model is USD 29.10 million in 2025 and USD 463.89 million by 2035. Our previous edition reported USD 185.37 million for 2025 on a top-down basis; the bottom-up rebuild lands at USD 237.12 million because 2025 cooling orders for 2026 completions are now counted.

Element	In this report	Why
Chillers, towers, dry coolers	Yes, USD 113.82 million (2025)	Core heat rejection
CRAH, in-row, rear doors	Yes, USD 85.36 million	Air-side heat removal
CDUs, facility liquid loops, immersion tanks	Yes, USD 23.71 million	Facility-side liquid cooling
Cooling electricity and water bills	No	Operating cost, not cooling sales
Server cold plates and fans	No	Bought with IT hardware

Buyers inside this scope include hyperscale cloud operators, colocation providers, Thai banks and government agencies running their own rooms, and small and medium-sized enterprises (SMEs) whose server rooms move into colocation halls.

What Is Driving Data Center Cooling Demand in Thailand?

Three Thai-specific forces add USD 1.42 billion of yearly cooling spend between 2025 and 2035: hyperscale cloud regions, the EEC water contracts, and the BOI efficiency tier.

AWS’s USD 5 billion and Google’s USD 1 billion cloud regions pull hyperscale cooling into Bangkok

Amazon Web Services (AWS) opened its Asia Pacific (Thailand) Region with three Availability Zones in January 2025 and plans to invest more than USD 5 billion in Thailand, according to the Amazon announcement. Google Cloud followed with a three-zone Bangkok region in January 2026 as part of a USD 1 billion investment, according to the Google Cloud release. DC Market Insights estimates hyperscale and cloud halls at USD 90.11 million of 2025 cooling spend, rising to USD 912.32 million by 2035 at 26.05% a year, the fastest data-center-type line.

Eastwater’s Chonburi water contract turns cooling design into a utility negotiation

The Bridge Data Centres contract with Eastwater Stecon Utilities caps water at 3.3 million cubic metres a year from May 2026, according to Kaohoon International (October 2025). Mongabay reported in April 2026 that more than 70 data center-related projects are planned or underway, mostly in the EEC, and that one facility’s water use equals about 37,000 residents. Each 100 MW moved from open towers to hybrid or dry heat rejection adds roughly USD 15-25 million of cooling equipment (DC Market Insights estimate), which is why Chillers and Heat Rejection still grows 17.70% a year even as its share falls.

The BOI 1.3 PUE tier rewards liquid cooling at investment-approval stage

The Board of Investment ties its higher data center incentives to construction and service standards, PUE and water management, according to the BOI data center promotion conditions; its high-efficiency tier asks for PUE of 1.3 or lower and GPU-ready halls (Mondaq, March 2026). Warm-water liquid loops cut chiller compressor hours in a 35 °C climate, so DC Market Insights models Liquid Cooling taking 34% of cooling spend by 2035, growing 37.29% a year.

How Are Thai Operators Changing Their Cooling Designs?

Two design shifts lift Liquid Cooling from 10% to 34% of spend by 2035 and move EEC heat rejection from open towers to hybrid systems.

AI halls reach two-thirds liquid by the early 2030s

True Internet Data Center (True IDC) opened what it calls Thailand’s first AI hyperscale data center, over 20 MW in Bangkok, in May 2025, and broke ground on a 250 MW AI campus in the EEC worth THB 77 billion (USD 2.36 billion) in April 2026 (Source: True IDC via The Nation and W.Media). DC Market Insights prices AI-hall cooling at USD 1.95 million per MW in 2025 against USD 1.45 million for a conventional hall, a 34% premium carried by CDUs, larger chillers and warm-water loops.

Thai suppliers localise cooling and power assembly

Delta Electronics (Thailand) reported 2025 sales of THB 198,514 million, up 20.3%, according to its Delta Electronics (Thailand) 2025 results filing, and the company builds data center power and thermal products in Thailand. Local assembly gives Thai buyers a second source for CRAH units and CDUs alongside imported chillers.

What Could Slow Thailand Data Center Cooling Spending?

Grid and water permits could cut 2035 spend by up to USD 562.13 million, the gap between the base and low cases.

EEC power plan of about 3,800 MW faces 10,000 MW of demand

The EEC Office said in August 2026 that long-term data center power demand could exceed 10,000 MW against a plan of about 3,800 MW (MGR Online). If 30% of 2027-2035 completions slip, the market reaches USD 1.10 billion rather than USD 1.66 billion by 2035.

Community resistance over water and missing impact studies

Prachin Buri residents gathered more than 11,207 signatures against EEC expansion in August 2026, according to MGR Online, and a subdistrict head told Mongabay that a 0.2-gigawatt hyperscale facility had no environmental impact assessment (EIA). The Office of National Water Resources (ONWR) said it has a water management strategy that protects farm and household supply. Each permit delay pushes cooling orders out by a year, worth about USD 2.05 million per MW of AI capacity.

Where Are the Best Cooling Opportunities in Thailand?

Retrofits and hybrid heat rejection hold the two largest open opportunities, together about USD 1.04 billion of 2035 spend.

Retrofitting Bangkok’s first-generation halls for 30 kW-plus racks

Bangkok’s installed base, most of it built before 2022 at 5-8 kW per rack, needs rear-door exchangers and CDUs to host inference clusters; the Maintenance, Service and Retrofit line grows 31.90% a year to USD 463.89 million by 2035 on 4,917 MW of installed IT load.

Hybrid and dry heat rejection for water-capped EEC campuses

The six EEC campuses tracked in the DC Exclusive table below carry 1,150 MW and about USD 2.36 billion of cooling content at USD 2.05 million per MW; a hybrid design that uses 35% of evaporative water would save 12.33 million cubic metres a year across them.

What Does Data Center Cooling Cost per MW in Thailand?

A conventional Thai data hall needs about USD 1.45 million of cooling per MW of IT load in 2025, and an AI hall about USD 1.95 million, per DC Market Insights.

Price point	2020	2025	2030	2035
Conventional hall cooling (USD million per IT MW)	1.30	1.45	1.60	1.70
AI hall cooling (USD million per IT MW)	1.75	1.95	2.15	2.25
Service and retrofit (USD thousand per installed MW a year)	60	75	90	100

Public anchors: True IDC’s EEC campus works out to USD 9.44 million per MW of total investment (USD 2.36 billion for 250 MW), so cooling at USD 1.95-2.15 million is roughly 21-23% of facility cost; Bridge Data Centres’ BOI-approved 134 MW Chonburi project is THB 24.6 billion (USD 746 million), USD 5.57 million per MW before IT (Thailand Business News, May 2026).

Which Rules and Standards Shape Thai Data Center Cooling?

Three rule sets shape about USD 446.25 million of 2026 cooling purchases: BOI promotion conditions, ERC energy rules, and water allocation in the EEC.

• BOI data center promotion (November 2025): construction and service standards, PUE and water management conditions; high-efficiency tier at PUE 1.3 or lower.
• BOI Subcommittee on Energy Management for Data Center Investment and Project Screening, chaired by the Minister of Energy (July 2026), screens power and cooling plans.
• ERC draft direct renewable power purchase agreement framework (October 2025): BOI-promoted data centers of at least 50 MW IT per building.
• ISO/IEC 27001 certification is required before the corporate income tax exemption applies (Mondaq, March 2026).
• ASHRAE TC 9.9 thermal guidelines and TIA-942 / Uptime Tier designs set inlet temperatures and cooling redundancy in Thai colocation contracts.

Which Cooling Technology Makes the Most Money in Thai Data Centers?

Sources for the megawatts: True IDC (April 2026), WHA Eastern Seaboard 4 via MGR Online (August 2026), Skyline and Bridge via Thailand Business News (May 2026), Bridge’s water contract via Kaohoon International (October 2025), NTT (July 2026) and the Digital Edge and B.Grimm Power green loan (May 2026). The ledger shows why water, not chiller price, ranks suppliers in the EEC: 18.97 million cubic metres a year on open towers versus 6.65 million on hybrid systems.

Which Thai Region Spends the Most on Data Center Cooling?

The Bangkok Metropolitan Region spends the most, USD 137.53 million in 2025, and the Eastern Economic Corridor grows fastest at 27.84% a year to USD 829.38 million by 2035, overtaking Bangkok around 2032.

Bangkok Metropolitan Region

USD 137.53 million in 2025, USD 597.16 million by 2035, 15.82% CAGR. Carrier hotels in Bangkok and Samut Prakan, AWS and Google zones and True IDC’s 20 MW AI hall keep the region at 36.0% of 2035 spend even as land and grid limits push new campuses east.

Eastern Economic Corridor

USD 71.14 million in 2025, USD 829.38 million by 2035, 27.84% CAGR. Chonburi, Rayong and Chachoengsao host True IDC’s 250 MW campus, NTT Bangkok 4, Bridge Data Centres and Skyline; water contracts with Eastwater set the cooling design here.

Other Central and Eastern Provinces

USD 16.60 million in 2025, USD 142.65 million by 2035, 24.00% CAGR. Prachin Buri and Ayutthaya industrial estates draw overflow campuses, but community petitions in Prachin Buri add permit risk.

North and Northeast

USD 9.48 million in 2025, USD 66.35 million by 2035, 21.48% CAGR. Khon Kaen and Chiang Mai host government and university rooms; the region holds 4.0% of spend.

Chonburi becomes the largest province by 2035 at USD 497.63 million, ahead of Bangkok at USD 364.93 million.

What If Thai Data Center Build-Out Slows or Speeds Up by 2035?

The 2035 Thailand Data Center Cooling Market ranges from USD 1.10 billion to USD 2.18 billion around the USD 1.66 billion base case.

Scenario	Assumption	2035 (USD million)
Low	Completions 30% lower from 2027 (EEC grid cap holds), AI share 10 points lower, prices 5% lower	1,096.63
Base	1,900 MW of completions 2026-2030, AI share 45% by 2030	1,658.76
High	Completions 25% higher from 2027, AI share 5 points higher, prices 5% higher	2,184.52

The low case sits closest to Ember’s October 2025 forecast of 6 TWh of Thai data center electricity demand by 2030; the base case follows the 2.5 GW of announced IT load recorded by Mondaq in March 2026.

Who Supplies Data Center Cooling in Thailand, and How Concentrated Is It?

The top five suppliers hold about 55% of 2025 Thai data center cooling revenue, a judgement-based DC Market Insights estimate (no supplier discloses Thai data center revenue); Daikin leads with about 13%.

Methodology: How Did DC Market Insights Size Thai Data Center Cooling?

DC Market Insights sized the market from 16 years of Thai IT completions (30 MW in 2020, 95 MW in 2025, 1,900 MW over 2026-2030, 600 MW in 2035) multiplied by cooling content per MW, plus service on the installed base.

The 2025 receipt: 132.5 MW booked (half of 2025 and half of 2026 completions) × USD 1.57 million blended cooling content = USD 208.02 million, plus 388 MW average installed IT load × USD 75,000 = USD 29.10 million, total USD 237.12 million. Inputs: 10, of which 4 carry a public fact. Bound checks: (1) ceiling, cooling equals 12.2% of the USD 1.95 billion Thailand Data Center Market total, inside the 11-15% reference band DC Market Insights uses for cooling’s share of capital spend; (2) ceiling, model completions of 1,900 MW in 2026-2030 equal 76% of the 2.5 GW announced pipeline; (3) floor, True IDC’s 250 MW EEC campus alone needs about USD 487.50 million of cooling, 47% of modelled 2026-2027 new-build spend of USD 1.04 billion. The AI-hall pricing matches the Thailand AI Data Center Market, and the global context sits in the Data Center Cooling Market and Data Center Chiller Market.
