Ekströms Värmetekniska AB
Ekströms Värmetekniska AB are a market leader in the design, and supply of Flue gas coolers, Economisers, Airpreheaters, Shot cleaning systems and extended surface heat transfer tubes, spiral finned or gilled tubes, for utility power generation, industrial processes and marine applications. During the 1920’s the product range was extended to address demands of the energy business sector. In 1949 Ekströms engineers pioneered the unique on line shot cleaning technique which remains in demand as the most efficient system for cleaning of heat exchangers operating in ash laden flue gases. More than 1000 shot cleaning systems has been delivered since this cleaning metod was introduced more than 50 years ago Our customers can be found all over the world.

- Year Founded:
The Ekströms Company was founded in 1905 by Arthur Ekström, who was an industrialist and engineering graduate from Chalmers University in Gothenburg. The original company name was A. Ekströms Maskinaffär AB. Initially the Company concentrated on machinery supplies to the emerging and rapidly expanding pulp and paper industry.
Market demands during the 1960’s attracted Ekströms to focus on thermal engineering, particularly in the development of extended surface economisers and airheaters which made significant contributions to plant thermal efficiencies.
In recognition of the increased involvement in thermal engineering the name of the Company was changed to Ekströms Värmetekniska AB in 1968. The heat exchanger products were further refined with the advent of single and double welded steel gilled tubes during the 1980’s enabling Ekströms to supply a far more cost effective product.
In more recent times during the 1990’s Ekströms have developed export business throughout Europe and Asia, as well as maintaining their service to valued customers in their home Scandinavian market and in the U.K.
In 2005 Ekströms started to collaborate with A&J Fabtech for manufacturing of Economisers for the UK Market.
All engineering practices at Ekströms and the manufacturing at Maskinarbeten are controlled in strict accordance with ISO 9001:2000/EN 29001. The Maskinarbeten workshop is accredited to SS-EN ISO 14001:1996 and maintains an Environmental Management System to minimise the disturbance to local, national and global environment.
The production of fin tubes fulfils the requirements of European standard EN 729-2. Material certificate EN 10240-3.1 is always supplied with our deliveries. On request we can supply shop inspection certificate 3.2 from inspection companies such as Lloyds register, DNV, Nippon Kaiji Kyokai, Bureau Veritas, ABS, etc.
Ekströms provides thermal and mechanical design of extended surface heat exchangers, such as Fin tube Economiser, Flue gas coolers and Air preheaters. All heat exchanger pressure parts are CE marked, inspected, radiographed, and hydraulically pressure tested in accordance with EU-PED 97/23/EC, EN12952 and EN13445 and also taking account of particular customer requirements.
We also offer site engineering services, particularly for supervision of installation and commissioning of shot cleaning systems.
