Industrial Heat Transfer Experts

Extran is a highly experienced, solutions-based heat transfer company, supplying Shell & Tube, Plate and Air Cooled Heat Exchanger to the Industrial sectors.

The Industrial Heat Transfer category covers a wide range of applications and our experience and depth of knowledge enables us to provide highly efficient heat transfer solutions across the entire sector.

Extran is a quality, competitive provider in terms of design, manufacture, supply, maintenance, cleaning and on-site service and Spare Part Supply.

Our in-house expertise enables us to address technically sophisticated projects and, through our partnerships with global leaders, a greater range of equipment supply.

Extran has the engineering depth for complex heat transfer solutions in both Thermal and Mechanical Design disciplines and code conformance requirements with design capabilities that include AS 1210, AS4041, ASME (Div 1 & 2), PD 5500, API661 and TEMA.
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 the equipment. Mechanical designs can be performed to any recognised standard, such as AS1210 or ASME VIII.

Extran has 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, in consultation and will work within required time frames. Extran personnel are able to visit sites to investigate problems or to provide quotes for units before they are removed from service.
