Testing facilities

Wind tunnel

There is a wind tunnel in the laboratory. During the development phase, it is possible to determine recirculation of flue gases in the air through-flow.

Boiler test

Pressure differences arising when installing the systems is a common problem. Using an extensive testing programme, the flue systems are designed so that they fit each individual boiler.


Using a special sprinkler installation, we can test how the products function during rainy weather. Various angles of impact on the product are evaluated.



Due to the increasing importance of quality materials, our materials—including any new additions—are

regularly tested to ensure the reliability of our products.



All our products can be subjected to temperature-based tests. It is important that no icicles remain suspended from the roof and facade penetrations in the winter. Temperatures as low as ‑20°C can be simulated in the laboratory to test this.
