Customized silencers are our specialty. We can produce a virtually infinite range of custom-built silencers in a wide variety of materials, sizes and shapes, including round, oval and rectangular cross-sections. If preferred, we can design your own range of silencers, as we did for some of the leading equipment and engine manufacturers.

Our modern 65,000ft² facility in Krimpen aan den IJssel, the Netherlands, is well-equipped for the production of silencers. All components are in-house engineered and manufactured. One of our main strengths is therefore a very short delivery time. Our logistics and expediting departments manage all of your shipping requirements, whether it is a simple accessory or a silencer.

More than 65 people are fully dedicated to the design, engineering and production of our products. These people, together with our well-equipped facility gives us the capability to handle orders of any size, any shape or complexity. Combining these product options with superior quality, innovation, competitive prices, great service and short delivery times makes TIO your perfect partner for your project.


We are committed to engineering excellence and to design the right silencer to meet your specific noise requirements, regardless of shape, size or complexity, from a cylindrical to a box-type silencer, from a single component to a turn-key application. Our engineers are ready for you - we carry out noise measurements, noise reports and acoustic calculations, as well as velocity and back-pressure calculations of your complete installation. In addition to this, we can also advise in vibration control, mounting, material selections and strength calculations.
