Industrial Temperature Control Services Market

A rental chiller is still sized in tons of refrigeration, a unit fixed at 12,000 British thermal units (Btu) an hour, or 3.517 kW, the heat that melts one short ton of ice in 24 hours. The industrial temperature control services market covers rented chillers, cooling towers, heaters and dehumidifiers deployed with engineering crews, plus installation, calibration and maintenance of process temperature control, sold to plants, refineries and data centres. Aggreko’s air-cooled rental chillers run from 10 to 420 tons and pull fluid down to -22°F (-30°C). Our receipt reads 1,186,400 jobs × USD 4,296 average invoice = USD 5.10 billion in 2025, rising to USD 9.11 billion in 2035 at a revenue CAGR of 5.98% for 2026 to 2035. The largest specialist, Aggreko, put its temperature control fleet on public record when it filed an amended F-1 registration statement with the Securities and Exchange Commission (SEC) on 17 September 2026. The study belongs to our heating, ventilation and air conditioning (HVAC) and building energy equipment hub, and every estimate follows the Douglas Insights research methodology.

Why are data centre heat loads and plant outages lifting demand for industrial temperature control services?

Job counts for industrial temperature control services climb from 1,186,400 in 2025 to 1,776,531 in 2035, or 4.12% a year, in our base case. Data centre and heat-wave cooling supply the largest share of that volume, followed by outsourced process cooling in new plants and by turnaround and refrigerant retrofit hires.

Data centre cooling and hotter summers

Data centres used about 415 terawatt-hours (TWh) in 2024, around 1.5% of world electricity, and the International Energy Agency (IEA) expects about 945 TWh by 2030, after growth of about 12% a year since 2017. Every extra megawatt of servers needs a megawatt of heat rejection, and commissioning teams rent chillers and load banks to test halls before permanent plant runs. Douglas Insights estimates 1.63 percentage points of the 4.12-point volume leg to data centre commissioning, interim cooling and summer peak hires. The same heat load is reshaping permanent plant, covered in our Data Centre Liquid Cooling Market report.

Outsourced process cooling in new and expanding plants

Manufacturers that add a line often rent a chiller for 6 to 18 months rather than wait for a permanent unit, and some keep the rental under a service agreement. Rental process cooling units from Trane Rental Services start at 3 to 40 tons, and its water-cooled chillers reach 225 to 1,000 tons, which covers most single production lines. We credit 1.38 percentage points of temperature control job growth to new plants, line expansions and the shift from owned to rented cooling, concentrated in Other manufacturing and Pharmaceuticals.

Turnarounds and refrigerant retrofits

Refineries and chemical plants schedule turnarounds every 3 to 6 years on our model, and each one hires chillers, cooling towers and heaters to keep units on temperature while permanent plant is opened. The hydrofluorocarbon (HFC) phase-down adds a second wave: owners replacing old chillers rent temporary cooling while the new low-refrigerant unit is installed. Douglas Insights models 1.11 percentage points of the volume leg as turnaround and retrofit hires, so the three drivers sum to 1.63 + 1.38 + 1.11 = 4.12 points.

The price leg contributes 1.79% a year. Multiplied with job growth, it yields the 5.98% revenue CAGR for industrial temperature control services, and the average invoice moves from USD 4,296 in 2025 to about USD 5,130 in 2035. Data centres, at 16.8% of 2025 value, are the end user adding temperature control jobs fastest.

What headwinds slow chiller rental and process cooling service contracts?

In our slower case, job growth for industrial temperature control services falls by 1.81 points, from 4.12% to 2.31% a year, and the 2035 value drops to USD 7.30 billion. Deferred plant capital budgets, idle rental fleet that pushes rates down, and electrical limits at sites explain the gap.

Capital comes first. When chemical and steel producers postpone line additions, the 6 to 18 month process cooling hires attached to them vanish with the project. We remove 0.74 points of temperature control volume for a two-year capital pause.

Spare fleet matters. Aggreko reports Group average physical utilization of 54% for its latest financial year, so close to half its assets sit off rent on an average day. Rental firms with spare chillers win jobs on price, and owners with spare in-house capacity skip the hire; that slack costs 0.61 points of volume.

Power is the last hurdle. A 1,000-ton water-cooled chiller rejects about 3,517 kW of heat and needs its own power feed, so constrained sites either rent generators as well or delay the job. Deferrals of that kind take away 0.46 points, and the three restraints total 0.74 + 0.61 + 0.46 = 1.81.

Which service segment makes the money: chiller rental, heating, dehumidification or maintenance?

Temporary chiller and cooling tower rental makes the most money, USD 2.13 billion or 41.7% of 2025 industrial temperature control services value on our model. Process chillers and towers carry the heaviest daily rates and the longest hires. The same segment also grows fastest, at 6.94% a year to 2035.

From USD 2.13 billion today, Temporary chiller and cooling tower rental nearly doubles to USD 4.16 billion by 2035. Data centre commissioning and process cooling hires lead, and each job pairs a chiller with pumps, hoses and often a cooling tower cell, which lifts the invoice.

Winter work defines Temporary heating and boiler rental, a USD 1.09 billion segment with 21.4% of value and the slowest rate, 4.38% a year. Indirect-fired heaters, temporary boilers and flameless units keep process lines and warehouses on temperature, so demand is seasonal. Readers sizing permanent heat supply can compare our Industrial Boilers Market study.

At USD 693.2 million, Dehumidification and air handling rental takes 13.6% of value and adds 5.61% a year. Desiccant dryers protect coatings work, tank linings and storage during outages, and air handlers move chilled air into halls with no ducting.

Process temperature control installation and maintenance services earn USD 1.19 billion, a 23.3% slice that reaches USD 2.02 billion at 5.43% a year. Calibration of controllers and sensors, installation of temperature control units and long-term service agreements make this the steadiest temperature control revenue.

How do chemical plants, data centres and food lines split temperature control service spending?

Chemicals and petrochemicals spend the most on industrial temperature control services, USD 1.40 billion or 27.4% of 2025 value on our model, because exothermic reactions and turnarounds need cooling that cannot fail. Data centres hold 16.8% and add the most new spending as commissioning loads climb.

Chemicals and petrochemicals carry USD 1.40 billion. Food and beverage takes 18.9%, or USD 963.3 million, for cold rooms, fermentation and seasonal production peaks. Data centres account for USD 856.3 million. Pharmaceuticals hold 12.3%, worth USD 626.9 million, where validated cooling keeps reactors and cold storage within tight bands. Other manufacturing, from steel to plastics moulding, takes 24.6%, or USD 1.25 billion.

By contract, Planned rental makes up 51.7% of temperature control services value, or USD 2.64 billion, Emergency rental 25.4%, or USD 1.29 billion, and Long-term service agreements 22.9%, or USD 1.17 billion. Emergency jobs price highest per day because crews ship in 24 hours or less; Carrier Rental Systems and Herc Rentals both run 24-hour emergency response for failed plant.

Where is temporary cooling and heating capacity rented most, and which region grows fastest?

North America rents the most industrial temperature control services, USD 2.18 billion or 42.8% of 2025 value on our model, because the United States has the deepest specialty rental networks. Asia Pacific grows fastest, at 8.13% a year to USD 2.19 billion in 2035, as chemical and data centre capacity expands.

At 5.62% a year, North America reaches USD 3.77 billion by 2035, led by Gulf Coast petrochemical turnarounds and data centre commissioning. Europe, worth USD 1.37 billion or 26.9%, posts the slowest rate at 4.71% and ends at USD 2.17 billion, because industrial capacity is flat and refrigerant retrofits supply much of its new work.

Asia Pacific opens at USD 1.00 billion, a 19.7% share, and its average job is the cheapest of any region at about USD 2,910 on our model. Mining, refining and food processing hires take Latin America from USD 275.2 million, 5.4% of value, to USD 489.1 million at 5.92% a year.

Our wildcard is the Middle East and Africa: USD 265.1 million today, 5.2% of value, and USD 489.4 million by 2035 at 6.32% a year. Gulf refineries hire large chiller and cooling tower packages during summer turnarounds, so a single project can shift the regional total by several points on our model.

Who wins temperature control rental contracts: Aggreko, United Rentals, Sunbelt or Trane?

Aggreko wins the most, with 14.6% of 2025 industrial temperature control services value, or USD 744.1 million on our model. Douglas Insights values the top three, Aggreko, United Rentals and Sunbelt Rentals, at 32.7% combined, and the seven named firms hold 49.2%, so the market stays fragmented among regional specialists.

Aggreko owns about 120,000 assets with 17 GW of capacity, of which 8.5 GW is temperature control and other fleet, and reported net revenue of USD 3.4 billion with data centres at 11% of revenue, according to its amended F-1 of 17 September 2026. The filing names the New York Stock Exchange (NYSE) ticker AGKO and says temperature control applications often require power as well. Douglas Insights puts temperature control at 21.9% of Aggreko revenue.

United Rentals follows with 9.7% on our model. Its specialty rental equipment revenue reached USD 4.64 billion, up 13.6%, and temperature control is one of several specialty lines alongside trench, fluid and power. Sunbelt Rentals holds 8.4%; the specialty segment of its parent earned USD 2.3 billion in rental-only revenue, up 11%, with power and HVAC inside it.

Trane Rental Services takes 6.2% with more than 2,500 pieces of equipment, more than 300,000 tons of capacity and 2,600 technicians, plus air-cooled chillers from 10 to 500 tons. Carrier Rental Systems holds 4.8% with chillers, cooling towers, boilers, heaters and dehumidifiers serving heavy and light industrial manufacturing.

Atlas Copco holds 2.9% after it acquired Delta Temp on 4 April 2024, a Belgian industrial cooling renter with 20 employees and about EUR 9 million of 2023 revenue. Herc Rentals holds 2.6% with portable units from 1 to 5 tons and fixed units up to 80 tons.

How much do plants pay per chiller rental week or temperature control maintenance visit?

An average industrial temperature control services job costs the plant USD 4,296 in 2025 on our model. A week of spot cooling starts near USD 450, while a month of a 400-ton chiller package reaches USD 38,000. Tonnage, hire length and emergency call-out set each invoice across that band.

Douglas Insights expects the average temperature control invoice to rise 1.79% a year, to about USD 5,130 in 2035. Mix explains most of it: more data centre and process chiller jobs, which run larger and longer, and more low-temperature units such as Atlas Copco’s rental chillers, which cover fluid from -12°C to 21°C at 50 kW to 720 kW. Rate inflation adds less, because 54% utilisation at the largest fleet keeps spare capacity on the market.

How long does a temperature control hire last, from emergency chiller call-outs to turnaround packages?

A typical industrial temperature control services hire lasts about 5.8 weeks on our model, within a wide range. Emergency chiller call-outs average near 2 weeks, turnaround packages 4 to 10 weeks and process cooling bridges 6 to 18 months. Length, more than tonnage, separates a USD 450 job from a USD 38,000 one.

Emergency rental, 25.4% of value, starts with a failed plant chiller and a crew that ships in 24 hours or less, then ends when the permanent unit is repaired. Turnaround work is booked months ahead, so fleets pre-stage chillers, towers and heaters near refinery clusters before the season.

Bridge hires form the long tail. A line that waits 6 to 18 months for a permanent chiller pays rental for the whole wait, which is why Planned rental, at 51.7% of value, outweighs emergency work by about 2 to 1.

Which refrigerant rules and F-gas standards shape rental chiller fleets?

Refrigerant rules shape about 26.9% of 2025 industrial temperature control services value directly, the European share, through the European Union (EU) fluorinated greenhouse gas (F-gas) regulation, and touch the North American fleet through HFC phase-down. Both force rental fleets to replace high-refrigerant chillers sooner than their mechanical life requires.

F-gas Regulation (EU) 2024/573 entered into force on 11 March 2024, adopted on 7 February 2024. It caps EU HFC production at 60% of the 2011 to 2013 average from 2025, falling to 15% by 2036, and sets an HFC phase-out by 2050, with stricter leak rules for installation and servicing. Rental chillers are serviced between every hire, so leak-check labour feeds the maintenance segment.

In the United States, the American Innovation and Manufacturing (AIM) Act authorises the Environmental Protection Agency to phase down HFC production and consumption. Fleet owners respond by buying chillers with lower-charge refrigerants, a cost we fold into the 1.79% price leg for temperature control services.

What if data centre builds stall: how far does the 2035 temperature control forecast swing?

Our three cases put 2035 industrial temperature control services revenue at USD 7.30 billion slower, USD 9.11 billion base and USD 10.7 billion faster. Data centre commissioning and plant capital budgets set the volume leg, while refrigerant transition and fleet utilisation set the price leg in each case.

Paused chemical spending, utilisation stuck near 54% and power-limited sites define the slower path. On the faster path, data centre electricity tracks toward the IEA’s 945 TWh for 2030 and fleets keep investing at the pace Aggreko set out in its 17 September 2026 filing, which reported data centre revenue of USD 391 million.

Volume wins. An extra point of annual job growth raises the 2035 total by USD 914.1 million; a point less trims USD 838.4 million. Four outside studies of neighbouring rental and service scopes put growth between 4.0% and 7.3% a year, median 6.22%; our 5.98% is 0.24 points lower because the price leg is held to 1.79%.

Douglas Exclusive: the Temporary Cooling Capacity Ledger

Douglas Insights built the Temporary Cooling Capacity Ledger as an estimate, not an official register, from 28 inputs. The inputs are one unit definition and 27 fleet figures published by Aggreko, Trane, Atlas Copco, Delta Temp and Herc. The model converts every disclosed rental cooling capacity into kilowatts so fleets quoted in tons, kW and GW can be compared.

The ledger counts capacity, not revenue. Finding one: rented temperature control units span 3.5 kW to 3,517 kW, a 1,000-fold range, which is why a USD 4,296 average invoice hides bands from a few hundred dollars to tens of thousands. Finding two: Aggreko’s temperature control and other fleet on rent, about 4,590 MW, equals 4.35 times Trane’s entire disclosed rental tonnage of 1,055 MW.

Scale differs. Trane averages 120 tons a piece, while Aggreko’s 120,000 assets average about 142 kW across power and cooling. The next edition adds fleets as more rental firms publish tonnage.

Which receipts and cross-checks support the 1,186,400-job temperature control model?

Five regional builds give 1,186,400 industrial temperature control services jobs in 2025, and at a USD 4,296 average invoice they produce USD 5.10 billion. Douglas Insights counts each region back to the global line to the job, and two outside reference points land within 7% of our figures.

By region, the build is: North America 403,216 jobs × USD 5,410; Europe 280,943 × USD 4,880; Asia Pacific 345,069 × USD 2,910; Latin America 84,938 × USD 3,240; Middle East and Africa 72,234 × USD 3,670. Jobs grow 4.12% and price 1.79%, so (1.0412 × 1.0179) minus 1 = 5.98%. In 2026 the model carries 1,235,280 jobs at a USD 4,373 invoice.

First outside check: a published value of USD 5.44 billion for temperature control rental sits 6.7% above our USD 5.10 billion, a gap explained by our narrower industrial scope. Second outside check: a published chiller rental value of USD 1.77 billion compares with our USD 2.13 billion chiller and cooling tower segment, which adds towers and a year of growth. Added together, the four segment forecasts reach USD 9.04 billion in 2035, 0.8% short of the USD 9.11 billion total.
