About Us

Transtherm is a leading designer and manufacturer of adiabatic coolers, air blast coolers, free coolers and pump sets.

We focus on manufacturing systems for applications including power generation, data centres, water-cooled chillers, induction heating, air compressors and other renewable energy and process cooling systems.

Our efforts have been recognised by the DCS Awards panel and we are proud winners of the ‘Data Centre Cooling Innovation of the Year’ Award.

Based in the UK, we are innovators of technologically-advanced cooling solutions that deliver industrial connectivity benefits, reduce energy and water consumption and automatically control Legionella risk. That’s why our products are the chosen option for some of the world’s most reputable OEMs.

Have you noticed our tagline? It’s ‘Smarter, Cooler, Easier’ – a description which, we believe, characterises how we work and what we create.


We work at the forefront of industrial and commercial connectivity, with integrated PLC (Programmable Logic Controller) interfaces as standard, tried and tested 3G connectivity for smart environments and a combination of temperature probes and read/write parameters for data collection and analysis.

We’ve automated Legionella control too, with integrated functionality designed to eradicate harmful bacteria automatically. Why not work with our specialists to understand how connecting your plant and adjusting the performance of your cooler could deliver facility wide efficiencies?


We strive to deliver optimum cooler performance for each individual project. Our mechanical engineers have the skills and experience required to develop bespoke product design alternations which suit challenging installation environments, working hands-on to create a cooling solution that is designed within your site’s exacting specification variables.

Our products are shipped from our UK factory, fully-built, with control panels supplied fitted and pre-wired. Every Transtherm work with regulatory bodies such as the Biological Agents Unit at the British Health and Safety Executive and the Institute of Sound and Vibration Research Centre to ensure our designs are safe and our standards uncompromising.


Did you know our sales force are all qualified and highly skilled mechanical engineers?

Taking a consultative approach to best practice specification, our experienced team will produce fit-for-purpose, data rich proposals designed to optimise cooler performance on a project-by-project basis. Don’t take our word for it though, we’ll provide you with all the thermal, acoustic, water and energy consumption and climatic data we’ve used to work out your achievable ROI, so that you can specify our products with complete confidence.

We’re proud to be a customer-centric, family owned and managed business. We work hard to maintain longstanding relationships with our customers, adding value to their supply chain with our efficient product specification processes, established logistics and delivery services, alongside fast, convenient installation and commissioning procedures.

But that’s enough about us, let’s talk about you. Give our dedicated team a call to discuss your requirement on 024 7647 1120.

What Transtherm's customers say...


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.

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..

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.

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.
