As a result of the eightfold growth in ballast production 1965-1975, Helvar built the most modern ballast factory in the world, in Karkkila, in 1973.
The high degree of automation, the large production volumes, cost-effectiveness, reliable products and professionally skilled staff, have all been key factors in Helvar’s success over the years. Thanks to the famous Helvar spirit, the factory is still one of the most efficient in the world, as well as one of the largest in Europe.
The impact of the 1973 oil crisis forced a change in the use of energy. From boundless consumption, energy efficiency became a part of the production of ballasts, as well as the mission of Helvar.
