We’re with you all the way
Over the years, we have grown and expanded, and today we have representatives in all the Nordic countries. We aim to be a Nordic maintenance and service partner for both the traditional liquid fuels sector and the growing segment of E-mobility.
Our journey begins
In 1917 engineer F. Wennström becomes the owner of Bergvalls metal foundry in Kungsör outside Eskilstuna. When moving to central Stockholm some years later, the company is renamed F. Wennströms Gjuteri och Metallfabrik (foundry and metal factory) and specialises in the manufacturing of couplings and valves.
Standardisation of a complete industry
In the beginning of the sixties, Wennstrom delivers couplings to all major oil companies. In 1964 we are the driving force in the standardisation of couplings in gas stations, resulting in the commonly adopted FW125 and FW135 screw fittings for the 4-refilling system.
First contact with Wayne
Ljungmans Verkstäder was a metal shop that also repaired ships. When Texaco placed an order for a device to distribute fuel, the model for the modern gas pump was born. In 1934 Ljungmans Verkstäder had manufactured and sold 6,000 dispensers in the Nordic countries. During the 2nd World War and when motoring had its breakthrough, the company expanded rapidly and began developing flow meters and pumps for depots and road tankers.
In 1986 Wennstrom buys the mobile division of Ljungmans Verkstäder from Dresser Wayne. It’s the beginning of a close collaboration between Wennstrom and Wayne (now part of Dover Fueling Solutions). It also means the Wennstrom product portfolio with PD-meters and gear pumps for road tankers and depots.
From open landscapes to mountains and fjords
We say “Hei” and take our first steps abroad by establishing of our Norwegian subsidiary.
A market revolution
Our patented system, FlowCheck, revolutionizes the market for electronic gas separators. At the time, gas separators were heavy, bulky and mechanical. Furthermore, they always had some petrol or diesel left in them, resulting in involuntary mixtures when changing product. With FlowCheck it became possible to monitor the fuel flow electronically and accurately and stop the delivery when air was detected in the flow. FlowCheck was smaller than its predecessors, and it was possible to place it lower down on the road tanker increasing the fall in height for gravity deliveries. FlowCheck is followed by other in-house systems for level detection and metering – products that, together with FlowCheck, give us a strong position for equioment för petroleum road tankers in Sweden.
We look to the east to Finland
Wennstrom enters Finland by acquiring Tam Tam Varuste, one of the leading suppliers of mechanical equipment for road tankers and service stations in Finland.
Establishment in South Africa
And south to Africa turns out to be a perfect market for FlowCheck thanks to high demands on theft protection and metering accuracy.
Current owners take the next step
Ulf and Kerstin Ekelund acquire the Wennstrom group through Ekelund Invest.
In (almost) all the Nordic countries
Wennstrom increases it´s presence in the Nordics with the acquisition of Dresser Wayne’s sales and service organisations in Denmark, Norway and Sweden. As a result, we grow to nearly 100 field technicians and become one of Northern Europe’s largest suppliers of services and maintenance for fuel stations.
Now building sites too!
In Skellefteå, we establish Wennstrom Entreprenad AB, specialists in drawing, constructing and adapting fuel stations in northern Sweden.
Spotless in Denmark
Now with 200 employees, we form Wennstrom Wash Systems joins us in Denmark, with complete wash systems for cars, trucks, buses and trains from Christ.
The fossil-free future
We become the majority owner in Wennstrom Net AS when Wennstrom Fuel Systems AS and Norsk Energiteknikk AS merge. Wennstrom Net AS is at the forefront of E-mobility in Norway and has a nationwide service organisation.
New members in the Wennstrom Group
In early summer, Wennstrom buys ELPM in Mariestad, Sweden. It means an increased focus on both E-mobility and construction. And in the autumn, Dansk El & Teknik and 30 electricians in Odense, Denmark, become a part of the Wennstrom Group.
In June 2022, the operations in Finland are expanded with the personnel of Sähköhovi. In addition to competence in electrics, the move also increases the number of service technicians for fuel sites and also the capacity for installation and service of wash systems for vehicles.
And in September 2021, the company LaddAlliansen becomes part of the Wennstrom Group further strengthening our presence, experience and competence within e-mobility for heavier vehicles such as buses and trucks.
E-mobility in Finnish?
Sähköhovi becomes part of our Finnish operations enabling us to move into price signs, wash system installations and maintenance, and, of course, e-mobility. We now have the Nordics covered when it comes to e-mobility!
New times, new name – Solutions & Service
Wennstrom has developed from a distributor of systems and products to an integrator that assists customers with complete solutions, a change we now also signal via our name.
Complete Solutions joins Wennstrom
In August, Complete Solutions ApS, consulting architects and engineers, becomes part of the Wennstrom Group. The company, which realized early on the importance of project management being carried out by committed and experienced project managers, works with everything from sketches, technical drawings and calculations, authority contacts, material selection and project management. The goal is to grow within existing operations in the Nordics as well as within new areas such as e-mobility. In addition, the company wants to take overall responsibility for larger industrial projects within, among other things, Power-to-X.
With openness, commitment and accessibility, we will make a positive difference to the environment and safety around fuel transports in the Nordics.
We want to be the natural choice when it comes to investments and maintenance of sustainable fuels. Together with our customers, suppliers and other stakeholders, we shall improve the Nordic environment for future generations.
We want to fulfil expectations and requirements by constantly working with improvements that add noticeable value, so our customers prefer us to others.
We always strive to reduce our environmental footprint – a work characterised by a holistic approach, understanding and participation. Our values are based on care, respect for the individual and equality. We are convinced that it will lead to well-being, development and results. By integrating sustainability in our business model, we will secure added value over time.
