Functional systems

For small and large projects

You can always turn to our sales team to help you plan your projects. We are a flexible company with in-house product development and programming based in Raisio, Finland. Our product range offers technical solutions for even the most demanding projects.

The product measurements have been carried out in an accredited laboratory by Insinööritoimisto W. Zenner Oy. The calculation programme on the website is also implemented by Insinööritoimisto W. Zenner Oy. The informative and reliable calculation programme is freely available to engineers to support project planning. The calculation programme calculates a wide range of values that support the overall success of projects, both in terms of sound and ventilation. At the request of engineers, we have also added our products to CADmatic and MagiCAD.
