About us

HIAK has been developing and marketing noise reducing products since 1947. The first product developed was a mobile silencer. It was used for function-testing the first jet aircraft used by the Swedish air force. The successful result, laid the foundations for the knowledge and experience required to develop industrial noise reduction solutions for a variety of applications.

HIAK possesses an extraordinary capacity to develop new products and solutions for optimised noise reduction. Over the years, we have built up a comprehensive portfolio of applications and solutions for the process, manufacturing and construction industries.

We have developed machine enclosures and silencers for, gas and steam turbines, the energy sector and the aeronautical industry. We also possess in-depth knowledge of the manufacturing processes behind the products we have in our solutions.

Thanks to our long and broad experience in noise reduction, our employees possess a remarkably deep pool of knowledge. That we consider, to be our most important resource.
