Combined silencers reduce engine and exhaust noise in motor vehicles and CHP (Combined Heat and Power) plants. This silencer solution combines the properties of both reflection and absorption principles, enabling the simultaneous attenuation of high and low frequencies. For noise reduction, a combined silencer must operate reliably even under persistently challenging weather conditions, vibrations, hot emissions, and pressure requirements. This is particularly essential in industrial applications.
Benefit from our extensive expertise in exhaust technology! We design and manufacture bespoke combined silencers for manufacturers of machinery, equipment, and vehicles. We handle all preliminary work regarding dimensions, arrangement, and materials for you. The performance of NovaNox® combined silencers is further enhanced by optimal utilisation of the available installation space, which improves the reduction of engine and exhaust noise. The selected materials also ensure that a NovaNox® combined silencer delivers its maximum performance.
NovaNox® combined silencers are manufactured from certified steel or stainless steel. The internal insulation material consists exclusively of first-class glass fibre wool, stainless steel wool, or rock wool. If your application frequently experiences condensate, we can optionally use insulation materials that do not absorb moisture. This prevents persistent formation of condensate inside the combined silencers, significantly extending their service life and ensuring reliable performance.
As a certified welding specialist, NovaNox® possesses extensive experience in welding technology and highly skilled personnel. Our combined silencers are produced using both automated and manual welding processes. Manual welding offers cost advantages and time savings, particularly for one-off productions and small to medium-sized batches. Hand-welded combined silencers are manufactured on modern welding tables. Our in-house jig construction ensures dimensional accuracy and lasting precision, even for higher tolerance classes.
State-of-the-art welding robots are employed in the automated welding process. The automated manufacturing process allows for production with short lead times and high efficiency, which is ideal for cost-effective production of high volumes with consistent quality. Automated welding is the optimal method for exceptionally high precision, enabling the implementation of highly complex combined silencers with stringent tolerance requirements.
Our versatile selection of pipe end finishing options ensures quick and straightforward installation in any assembly situation. These include beads according to DIN 71550 and DIN flanges, as well as expansions and reductions tailored to your requirements. Furthermore, pipe ends can be slotted or supplemented with threaded connections, cutting screw fittings, or male and female sleeves.
Surface treatments provide a permanently corrosion-free, secure, and robust surface. This increases the longevity and safety of the combined silencers and gives them an appealing appearance. With our in-house powder coating and painting facility, we can quickly achieve all RAL colours to a high standard. For optimal corrosion protection, we offer heat-resistant coatings, galvanising, and powder coating, as well as pickling and passivation. Do you have a specific question?
