  • The essence of Scandinavian durability

    The essence of Scandinavian durability

    The WT-V buffer tank is made from black carbon steel, which has two advantages: it is resistant to corrosion and other chemical deterioration and performs better than most other materials in environments that experience a high level of shock and vibration.

    Moreover, black carbon steel can be produced from recycled materials and is easy to recycle later, meaning fewer CO2 emissions. These characteristics make black steel a great choice for projects that prioritize minimizing environmental impact.

Quality is part of our DNA

We have always followed the same basic philosophy: to have the best products on the market. Or in the words of Thermia’s founder, Per Anderson himself: “The products one releases must be not only the best of their time, but before their time, over time.”

To this day, this philosophy forms the backbone of all products developed by Thermia.
