Reflection silencers attenuate engine and exhaust noises in automotive and CHP plant applications. A reflection silencer utilises the reflection principle, primarily reducing low sound frequencies. Inside reflection silencers, there are usually two or more chambers of different sizes.
In these chambers, incoming sound waves meet reflected sound waves. The reflection reduces the sound energy. This type of silencer is frequently used with non-turbocharged engines or for compressed air applications. A reflection silencer must reliably perform noise reduction even under persistently challenging weather conditions, vibrations, hot exhaust gases, and extreme pressures. This is significant in industrial settings.
Thanks to our extensive experience in exhaust technology, we develop and build custom reflection silencers for manufacturers of machinery, systems, and vehicle technology. We fully design the dimensions, construction, and materials.
This enables efficient use of installation space, which in turn positively impacts the performance of NovaNox® reflection silencers. Engine and exhaust noises are significantly reduced as a result. Furthermore, materials are selected to optimally utilise the performance capabilities of NovaNox® reflection silencers.
NovaNox® reflection silencers are manufactured from certified steel or stainless steel. Only high-quality glass wool, stainless steel wool, or rock wool is used for internal insulation. We employ moisture-repellent insulation materials when high condensate formation is expected in an application.
This prevents persistent condensate build-up in the reflection silencer. Consequently, the reflection silencer maintains its performance even with high moisture levels and achieves a significantly extended service life.

Manual Welding
Our trained personnel reliably apply the expertise in welding technology that NovaNox® has acquired over many years as a certified welding specialist. We utilise both automated and manual welding processes for the production of our reflection silencers. Manual welding benefits single unit productions, as well as small and medium series, through lower costs and shorter production times. Hand-welded reflection silencers are produced on modern welding tables. Our in-house jig construction ensures dimensional accuracy and consistent repeatability – even with high tolerance ranges.
Automated Welding
Our state-of-the-art welding robots handle the automated welding process. The automated manufacturing process ensures very rapid and economical production. Therefore, it is the preferred choice when large quantities of consistent quality are to be produced at the lowest possible cost. The automated welding process also yields the most precise results. This allows for the implementation of highly complex reflection silencers with demanding tolerance requirements.
With our numerous options for tube end finishing, assembly is straightforward in any installation situation. In addition to beads according to DIN 71550 and DIN flanges, we implement expansions and reductions according to customer specifications. If required, tube ends can be slotted or fitted with threaded connections. We also offer cutting screw connections or male and female sleeves.
Surface treatments are a method to optimise the longevity, safety, and appearance of your reflection silencers. A permanently corrosion-free, protected, and robust outer shell enhances the service life of the reflection silencer. It also improves the aesthetics of the reflection silencer. Our in-house powder coating and painting facility enables surface customisation in all RAL colours, quickly and to a high standard. Optimal corrosion protection is achieved through heat-resistant coatings, galvanising, powder coatings, as well as pickling and passivation.
