Where we work:


Industrial Heat Transfer Experts

Extran has extensive experience in the Petrochemical sector, providing reliable, high performance and cost-effective heat transfer solutions for Refinery applications and Chemical processing plants.

We specialise in the design, manufacture, supply, service and maintenance of heat transfer equipment and our experience in the Petrochemical Industry enables us to tackle more technically sophisticated projects and to provide fast turnarounds to minimise down time.

On-Site Solutions

Together with our extensive testing procedures, Extran draws upon our in-depth knowledge of heat transfer theory and practical construction methods to accurately investigate the performance of existing heat transfer equipment. We are on hand to perform on-site equipment audits and to suggest the most effective solutions to improve performance. Prior to any physical work commencing, we will model alternative scenarios in order to accurately predict the effects of any change. Our capabilities extend to in-house thermal and mechanical design, drafting and manufacture with a focus on providing solution-based packages for all stages, from concept design through to commissioning.

In-House Design

We use the latest Thermal Design Software for new installations and projects or to model changes for existing process equipment. Our engineers will work with you and the data supplied to design your heat transfer equipment within the constraints set down in your specifications. We are also able to provide design options that will minimise cost and optimise performance of your equipment. Mechanical designs can be performed to any recognised standard, such as AS1210 or ASME VIII.

From the thermal design stage we then provide mechanical calculations and drawings to enable you to preview the proposed solution.

We have the capabilities to manufacture Heat Exchangers from either existing information or from designs developed in-house. New units are manufactured in line with any required standards such as AS1210, TEMA or API. Full traceability of all designs, components, manufacturing methods and tests is provided through our job tracking system and the production of an MDR.
All work is produced in accordance with our DNV certified ISO 9001 Quality System. Testing of the pressure and air movement equipment is conducted using calibrated test gauges and measurement tools and documented on test certificates.

Extran also maintains existing units to all of the above standards.
We are flexible in our scheduling and will work within required time frames. Extran personnel are on hand to visit sites to investigate problems or to provide quotes for units before they are removed from service.


Extran’s Maintenance Workshop has an enviable reputation for fast, efficient service, rebuild and repair of Heat Exchangers, Oil Coolers, Air Coolers, Plate Heat Exchangers, Shell and Tube Heat Exchangers and Industrial Radiators.

We also offer a comprehensive on-site maintenance and cleaning service.

All work carried out is in accordance with written work instructions as per ISO 9001 and with test certificates issued upon request.
