Icing wind tunnelVTT icing wind tunnel serves testing and verification
of products and concepts. The tunnel is located
inside a climate chamber which allows wide variety
of testing conditions based on customer needs.
The combination of low running costs and high
competence of personnel make this facility a unique
possibility for trying out new ideas, functionality of
prototypes, design optimisation, and verification of
products in controlled environment.
