Who are using Transtherm's Air Blast Coolers | Dry Coolers?


Aberdeen International Business Park

Transtherm supplied 6 x 450kW Air Blast V-Coolers to the M&E contractor on this job. Given the site’s proximity to the coast materials of construction were upgraded to suit.


ITV / Granada Studios - Manchester

Air Blast Coolers and Adiabatic Coolers were supplied for installation at the set of Coronation Street to dissipate the heat generated by the on-site CHP (Combined Heat and Power) and absorption chiller systems.


Vodafone - Dublin

2 x 8 Fan and 1 x 14 Fan Transtherm V-style Air Blast Coolers have been supplied to this site over two phases. The coolers were all painted for aesthetic purposes and supplied with coil protection mesh to help avoid debris being sucked into the heat exchange coils.

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.

Mark Mickleburgh
Senior Project Manager, Briggs and Forrester

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..

Senior Project Manager, Briggs and Forrester

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.

Paul Nile
Maintenance Manager, University of Plymouth

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.
