Exhaust Silencers

AXCES has a wide range that covers all applications and engine sizes. These silencers are divided in series depending on the application, damping technique and the desired damping levels.
 

 

Silencer Types|Principles

 

Absorption Type

 

The noise is absorbed by specific acoustical fibre inside the silencer. The Absorption Type silencer is most effective in the middle and high frequency range.

 

Reflection Type


The noise is reduced by creating a gas flow through separate chambers in the silencer. The Reflection Type silencer is most effective in lower and middle frequency range.

 

Reflection|Absorption Type


The Reflection | Absorption Type silencers are based on a combination of absorption and reflection damping techniques in order to reduce the noise in the complete frequency range.


 

Silencer Types With Integrated Spark Arrestor


Axces silencers can be equipped with an internal spark arrestor. Axces spark arrestors are DNV and RMRS type approved.


 

Spark Arrestor with damping


Axces has a wide range of Spark Arrestors with Damping which can be mounted in the exhaust gas system. Axces spark arrestors are DNV and RMRS type approved.

Pipe Diameter

The silencer size is important as well as the pipe diameter of the exhaust system. We will calculate the optimal diameter and silencer for your engine.

NOx Reduction catalyst and Integrated Silencer

 

Cuistom made Exhaust Silencer

Engineering turns theory into practice. With a strong expertis both in acoustics and physics .AXCES specializes in custom engineering, specifically in the fields of shipping, engine power, energy systems and automotive.


When it comes to fully integrated exhaust gas systems for combustion engines, AXCES covers every aspect that matters.


AXCES is a single partner providing clients with everything they need, from the smallest accessory to fully customized solutions. Truly a one stop shop in industrial exhaust systems.

 

Integrated Silencer - SCR Reactor

Moving forward towards 2016 and in-line with current EPA and IMO standards. regulating the release of harmful NOx compounds from exhaust systems.


The integrated SCR/silencer reactor is a novel solution making AXCES a market leader in this field. The new IDE - NOx reactor can be swapped with the existing noise reduction elements.


This upgrade of reactor leads to a reduction in the release of toxic NOx compounds through selective catalytic reduction, at the same time operates as a exhaust silencer.
