Data Center Refrigerant Market Size, Share & Forecast to 2035

The Data Center Refrigerant Market covers the refrigerant gases that data centers buy to charge and service their mechanical cooling plant: hydrofluorocarbon (HFC), hydrofluoroolefin (HFO) and natural refrigerants filled into chillers, direct expansion (DX) computer room air conditioners (CRAC) and in-row units, and pumped two-phase cooling loops. DC Market Insights values the global Data Center Refrigerant Market at USD 104.94 million in 2025 and forecasts USD 254.42 million by 2035, a compound annual growth rate (CAGR) of 9.26%. The build receipt: about 12.0 GW of new information technology (IT) capacity in 2025 needed about 2,000 tonnes of new refrigerant charge worth USD 39.87 million at original equipment manufacturer (OEM) bulk prices, and the 23,239 tonnes already installed in operating sites took 1,394 tonnes of service top-up worth USD 48.80 million plus USD 16.27 million of retrofit and recharge gas, which adds up to USD 104.94 million. Natural refrigerants grow fastest at 25.50% a year because the European Union (EU) F-gas Regulation sets lower global warming potential (GWP) ceilings each phase, and the Middle East and Africa is the fastest-growing region at 12.46% a year as new campuses there rely on mechanical cooling in hot climates.

Executive Summary

The Global Data Center Refrigerant Market size was valued at USD 46.34 million in 2020, reached USD 104.94 million in 2025, and is anticipated to reach USD 254.42 million by 2035, at a CAGR of 9.26% during the forecast period.

Data Center Refrigerant Market, CAGR	9.26%
Data Center Refrigerant Market Size 2035	USD 254.42 Million

DC Market Insights estimates that refrigerant spending by data centers grew 17.76% a year between 2020 and 2025, faster than new capacity, because the blended contractor price of refrigerant rose from about USD 22 per kg to about USD 35 per kg as the United States (US) American Innovation and Manufacturing (AIM) Act phase-down and the EU F-gas quota cut HFC supply. Value rose 17.1% in 2025 over the USD 89.65 million of 2024. From 2025 to 2035 the forecast slows to 9.26% a year: new capacity more than doubles to 27 GW a year, but AI halls cool most of their heat with liquid loops and dry coolers, so only about 30% of AI hall heat runs through vapour-compression plant against 80% in a conventional hall. Service gas stays the largest channel at USD 48.80 million in 2025, 46.5% of value, because every operating chiller and CRAC unit leaks and is topped up each year.

Market Scope: What Does the Data Center Refrigerant Market Cover?

The Data Center Refrigerant Market is measured as the value of refrigerant sold for data center cooling, at OEM bulk prices for factory and site charge and at contractor prices for service gas, in current US dollars. It totals USD 104.94 million in 2025.

How the segments fit together

Each kilogram is counted once. Refrigerant type, application, sales channel and data center type are four views of the same USD 104.94 million, and each split sums to the total in every year from 2020 to 2035. The DC Exclusive matrix crosses application with sales channel.

Market Drivers: What Drives the Data Center Refrigerant Market?

1. New capacity adds about 2,000 tonnes of charge a year

DC Market Insights estimates 12.0 GW of new IT capacity in 2025, rising to 22 GW in 2030 and 27 GW in 2035. With cooling plant sized at 1.2 kW per kW of IT for redundancy and a large air-cooled chiller holding about 0.16 kg of refrigerant per kW, the new-build charge rises from about 2,000 tonnes in 2025 to 3,743 tonnes in 2035. The charge figure comes from manufacturer data: Airedale’s I-Chill IZ4 R-1234ze chiller range lists 140 kg across two circuits for a 966 kW unit (Airedale technical manual), and Carrier sells its AquaForce 30XF air-cooled screw chiller from 390 to 2,100 kW on R-1234ze (Carrier).

2. Regulation forces a refrigerant change in every new unit

The US Environmental Protection Agency (EPA) Technology Transitions rule sets a GWP limit of 700 for data center, computer room air conditioning and IT equipment cooling systems installed from 1 January 2027, after a 700 limit for chillers from 1 January 2026 (EPA, page updated August 2026). Schneider Electric states that R-410A and R-407C, used by most data center air conditioners today, are well above this limit (Schneider Electric, April 2026). Each switch moves spending from HFCs at about USD 31 per kg to HFO and A2L gases at USD 33-49 per kg, which DC Market Insights models as a 14% rise in the blended contractor price between 2025 and 2035.

3. The installed bank keeps service demand rising

The installed refrigerant bank in data centers grows from 23,239 tonnes in 2025 to 45,309 tonnes in 2035 as the installed IT base rises from 116 GW to about 314 GW. A 6% annual top-up rate on that bank gives 1,394 tonnes of service gas in 2025 and 2,719 tonnes in 2035, worth USD 48.80 million and USD 108.74 million at contractor prices.

Market Trends: What Are the Key Trends in the Data Center Refrigerant Market?

HFO chillers become the default for large sites

HFO and HFO blend refrigerants grow 18.12% a year, from USD 23.09 million in 2025 to USD 122.12 million in 2035. STULZ has moved its chillers to R-1234ze with a GWP of 1 and its medium multi-scroll chillers from R-410A to R-454B with a GWP of 466 (STULZ).

Pumped two-phase cooling arrives with AI racks

Pumped two-phase cooling is the fastest-growing application at 35.70% a year, from USD 2.02 million in 2025 to USD 42.77 million in 2035, as DC Market Insights expects 10% of AI hall capacity to use two-phase cold plates by 2035 against 2% in 2025. Solstice Advanced Materials lists cold-plate liquid cooling among its two-phase applications for data centers (Solstice Advanced Materials).

Pumped refrigerant economisers cut compressor hours

Vertiv’s Liebert DSE system uses pumped refrigerant economisation, and Digital Realty reported more than four years of use of the technology when Vertiv launched 250 kW and 400 kW versions in December 2017 (DCD, December 2017). DC Market Insights counts the refrigerant in these systems within DX Precision Air Conditioning, which reaches USD 68.08 million by 2035.

Market Challenges: What Holds Back the Data Center Refrigerant Market?

Liquid cooling removes refrigerant from most AI heat

In an AI hall, DC Market Insights assumes only 30% of the heat passes through vapour-compression plant, against 80% in a conventional hall. As AI halls rise from 35% to 66% of new capacity, the mechanical share of new heat falls from 62.5% in 2025 to 47.0% in 2035, which cuts about USD 22 million from the 2035 new-build charge compared with a constant mix.

Price swings in the HFC market

The EPA’s July 2026 draft analysis of HFC allocation data notes that standard contractor-sized cylinders of R-410A were being sold at one-third of the expected cost in 2024, and that US HFC consumption has been much closer to the yearly limit under the AIM Act (EPA, July 2026). A 10% fall in the blended price would remove USD 10.49 million from the 2025 value.

Market Opportunities: Where Are the Opportunities in the Data Center Refrigerant Market?

Retrofit of legacy R-410A units: USD 36.25 million by 2035

Retrofit and recharge gas grows from USD 16.27 million in 2025 to USD 36.25 million in 2035 as operators recover high-GWP charge from older CRAC units and refill with R-513A or R-454B. Suppliers that pair reclaim services with new gas sales can reach this pool.

Two-phase fluids for AI racks: USD 42.77 million by 2035

Chemours agreed in May 2025 that Navin Fluorine International will manufacture its Opteon two-phase immersion cooling fluid, with an ultra-low GWP of 10 and capacity beginning in 2026 (Chemours, May 2025). Pumped two-phase refrigerants for cold plates add USD 40.75 million of new value between 2025 and 2035 in the DC Market Insights model.

Pricing: How Much Does Data Center Refrigerant Cost per kg?

DC Market Insights estimates a blended contractor price of USD 35.00 per kg in 2025, and OEM bulk buyers pay about 55% of that, or USD 19.25 per kg. New-build refrigerant content was about USD 3,323 per MW of new IT capacity in 2025.

Year	Blended contractor price (USD/kg)	OEM bulk price (USD/kg)	New-build refrigerant per MW of IT (USD)
2020	22.00	12.10	2,681
2025	35.00	19.25	3,323
2030	37.50	20.62	3,447
2035	40.00	22.00	4,053

Public price anchors: a Washington State contract catalogue lists R-410A at USD 349.00 for a 25 lb cylinder (USD 30.78 per kg), R-134a at USD 349.90 for 30 lb (USD 25.71 per kg), R-513A at USD 519.90 for 30 lb (USD 38.20 per kg), R-454B at USD 439.90 for 20 lb (USD 48.49 per kg) and R-32 at USD 300.00 for 20 lb (USD 33.07 per kg) (Washington State Department of Enterprise Services). A US electrical distributor lists a 20 lb R-454B cylinder at USD 823.59, or USD 90.78 per kg (Elliott Electric Supply).

Standards and Regulation: Which Rules Govern Data Center Refrigerants?

• US AIM Act Technology Transitions (40 CFR Part 84, Subpart B): GWP limit of 700 for data center, computer room air conditioning and IT equipment cooling systems from 1 January 2027; 700 for chillers with exiting fluid at or above -30 °C from 1 January 2026 (EPA).

Forecast Scenarios: What Is the Range for Data Center Refrigerant Spending in 2035?

DC Market Insights puts 2035 refrigerant spending between USD 181.59 million and USD 331.78 million, with a base case of USD 254.42 million.

Scenario	2035 (USD million)	Assumptions
Low	181.59	4% top-up rate, prices 10% lower, 15% less new mechanical cooling
Base	254.42	6% top-up rate, USD 40 per kg contractor price in 2035
High	331.78	8% top-up rate, prices 10% higher, 10% more new mechanical cooling

Under the low-case assumptions the 2025 value would be USD 79.81 million, so the top-up rate is the single largest uncertainty in the model.

Methodology: How Did DC Market Insights Size the Data Center Refrigerant Market?

DC Market Insights built the estimate bottom-up from 16 annual capacity cohorts from 2020 to 2035, split into conventional and AI halls. New-build refrigerant equals new IT MW × 1.2 kW of cooling plant per kW × the share of heat on vapour-compression plant × charge per kW (0.16 kg for chillers, 0.55 kg for DX units, 0.40 kg for pumped two-phase loops) × the OEM bulk price. Installed-base refrigerant equals the installed bank × a 6% top-up rate at contractor price plus a 2.5% retrofit and recharge rate.

The 2025 model in numbers: 12.0 GW × 1.2 × 62.5% mechanical share gives 9.0 GW of new vapour-compression plant and about 2,000 tonnes of charge worth USD 39.87 million; the 23,239-tonne installed bank × 6% gives 1,394 tonnes of top-up worth USD 48.80 million; retrofit gas adds USD 16.27 million; total USD 104.94 million.

Three bound checks hold:

• Ceiling 1: the 2025 value of USD 104.94 million is 5.1% of Chemours’ 2025 TSS net sales of USD 2,066 million, one supplier’s refrigerant segment.
• Ceiling 2: pricing all 3,975 tonnes bought in 2025 at the highest public anchor, USD 90.78 per kg, gives USD 360.85 million, above the estimate.
• Floor: the 2,000 tonnes of new charge alone at the lowest public anchor price (R-134a, USD 25.71 per kg) × 55% OEM discount gives USD 28.28 million, below the estimate.
