About Us

Smarter Cooling Solutions

At Transtherm Cooling Industries Ltd, specifying cooling systems is simpler. Our Smarter approach is built on over 40 years of cross-sector experience in process cooling and fluid distribution.

We support OEMs, resellers, and end users with dependable products and expert technical advice. Our air blast coolers, adiabatic coolers, coolant distribution units (CDUs), and packaged pump sets are engineered to exact specifications, reducing project risk, design time, and aftersales issues.

Though UK-based, we are a global supplier of cooling systems, with OEM and reseller customers across Europe, Middle East, Africa, North America and Asia. Partner with Transtherm for optimal performance, energy efficiency, and long-term reliability wherever your projects are located.

Cooler, Quieter, More Reliable

Our Cooler approach ensures reliable, efficient cooling performance for industrial and commercial applications.

Every Transtherm cooling unit is engineered for long-term durability and honest performance. We test cooling performance to BS EN 1048:2014 and noise levels to BS EN 13487:2019 standards, ensuring compliance and acoustic transparency. Using weather data from over 8,000 global weather stations, we match every adiabatic cooler, air blast cooler, or packaged pump skid precisely to its operating environment.

This commitment to robust engineering protects end-user systems, optimises energy use, and maintains performance in all climates.

Easier to Specify, Install & Maintain

Our Easier approach simplifies every stage of a cooling project — from quotation to commissioning.

Comprehensive data at quotation stage: environmental performance, acoustic reports, footprint dimensions, and CAPEX/OPEX breakdowns.
Fully documented engineering support: GA drawings (DWG/PDF) with 3D BIM-ready models available on request.
Plug-and-play solutions: all equipment is pre-commissioned and factory-tested at our UK facility, reducing on-site labour and installation time.
Integrated systems: Transtherm acts as your single point of responsibility for cooling and pumping solutions, removing the need to coordinate multiple suppliers.

This streamlined approach ensures faster project delivery, lower risk, and smooth, hassle-free commissioning.

Frequently Asked Questions (FAQs)

Who manufactures Adiabatic Coolers in the UK?

Transtherm Cooling Industries Ltd is a UK-based manufacturer of adiabatic coolers, supplying OEMs, resellers, and end users worldwide. Our systems are engineered for energy efficiency, reliability, and compliance with international standards.

What is the difference between an Air Blast Cooler and an Adiabatic Cooler?

An Air Blast Cooler uses ambient air to cool process fluids, making it ideal for moderate climates. An Adiabatic Cooler pre-cools the incoming air with water during hot weather, ensuring reliable cooling even in higher ambient temperatures. Transtherm designs and manufactures both technologies, helping you select the right solution for your project.

What industries use Transtherm cooling systems?

Our Air Blast Coolers, Adiabatic Coolers, Coolant Distribution Units (CDUs), and Packaged Pump Sets are used across multiple industries, including:

Data centres and IT cooling
Renewable energy systems (e.g. hydrogen electrolysers, battery storage)
Industrial process cooling
Food and beverage manufacturing
HVAC and building services

Does Transtherm supply packaged pump sets?

Yes. Transtherm manufactures Packaged Pump Sets and Coolant Distribution Units (CDUs) that are factory-tested, pre-commissioned, and supplied as plug-and-play solutions. These reduce on-site labour, speed up installation, and ensure system reliability.

Can Transtherm supply globally?

All equipment is tested and pre-commissioned at our UK facility. We design using global weather data from over 8,000 stations, comply with standards such as BS EN 13487:2019 for acoustic testing, and provide full technical documentation with every order.

What Transtherm's customers say...

Briggs and Forrester

Transtherm’s adiabatic technology is an efficient, reliable and high-quality solution for directly cooling data centres in which the server temperature parameters allow for the eradication of compressor or refrigerant based technologies.

Their designs are based on real time weather data for the installation site and their knowledgeable team of mechanical engineers can quantify any specification decision with independent research and testing results for complete peace of mind.

Senior Project Manager, Briggs and Forrester

NGD

Completing a build of such scale and complexity within just 16 weeks requires suppliers to adjust the design and build of their products in accordance to the build schedule and deliver them just in time for installation to prevent costly delays to NGD and our local contracting firms. The solution provided by Stulz and Transtherm is a great example of how data centres can work with trusted, reliable and dedicated supply chain partners..

PHIL SMITH

Uni of Plymouth

We were ultimately thrilled with the decision to upgrade to a new ambient-only cooling system, rather than simply switch the old chillers for a like-for-like replacement; something which we didn’t think was achievable within our original budget.

Commissioned during one of the hottest UK summers on record, the new system has already demonstrated its performance credentials and we are delighted with the results.

Maintenance Manager, University of Plymouth

Wessex Water

With a dramatic increase in digestion capacity and therefore gas production, the CHP system was working harder than ever before. With the CHP plant working harder, the original coolers were running at higher fan speeds for prolonged periods in order to manage the increased heat dissipation requirement.

It was clear the current cooler specification simply wasn’t able to maintain the engine and intercooler temperatures required for optimum engine performance. This was the point we turned to Transtherm.

MEP Studio

Working with Transtherm and the team of engineers from Geoffrey Robinson, we were able to clarify a number of sensible operating conditions in accordance to ARUP’s requirements...

In a project like this one, the keys to success are undoubtedly collaboration and communication up and down the supply chain, ensuring that any changes to the specification are quickly and efficiently implemented.

Senior Mechanical Engineer, MEP Studio

Geoffrey Robinson

By working with Transtherm, we have been able to dramatically reduce both the initial capital expenditure and future operating expenditure. The solution is also far more energy-efficient than alternative systems too, delivering considerable savings in electricity and huge reductions in water consumption over comparable adiabatic air-cooling systems. With sustainability key to the successful delivery of the project, the Transtherm system ticks all of the boxes.
