We pursue approaches to materials, designs and processes in order to fully optimize the life cycle, cost-effectiveness and function of ventilation systems and components.

Occupying a leading position in the market with sustainable silencers

Splitter silencers are mass-produced goods which are used in ventilation, air-conditioning and process air systems. They help us to work, learn and grow up in clean and well-ventilated environments, and also condition our process air. But what impact do the silencers themselves have on our carbon footprint? And how can we reduce and further optimize this footprint for the future?

Sustainability is one of the key challenges of our time. Together with you, as a manufacturer of silencers, we want to address this issue and rethink the product of splitter silencers. Besides all other required properties, we focus on energy efficiency and sustainability. We also take a close look at the materials that are currently used to make them. Our goal is to develop a recyclable splitter silencer that is gentle on raw materials, meets all requirements, and also conforms to a certified sustainability standard. Are you interested in a cooperation? We look forward to hearing from you!

Our services at a glance:

  • Assessment of the CO2 footprint and life cycle of a splitter silencer
  • Identification of alternatives to mineral wool and sheet steel
  • Life cycle assessment of conventional splitter silencers
  • Offer to develop sustainable silencers
  • Life cycle assessment of sustainable and recyclable splitter silencers
  • Calculation of pressure loss coefficient (direct relationship to energy efficiency) in the silencer test rig
  • Determination of the acoustic effectiveness of new absorber concepts in the impedance tube and as a splitter in the silencer test rig

The life cycle of silencers in process air and HVAC systems needs to be improved by taking new approaches to materials and design in order to fully optimize their cost-effectiveness and function.
