BDLD is a curved rectangular silencer with convensional design with width and height dimensions that doesn´t exceed the present connection dimensions. The silencer can be produced in all normally existing duct dimensions.
BDLD has an external shell of trapezoidal corrugated sheet metal for stabillity and reduced risk of oscillation.
BDLD is designed for low pressure drop with baffle combinations that attenuate aspecially low frequences well.
The type of insulation material is developed to provide good sound properties, low weight and to be cleanable.
BDLD meets the requirements of air tightness class C.
Tools for dimensioning and planning
The software DIMsilencer is recommended for fast choise of silencer or a complete and fast sound calculation of the duct system.
The software CADvent offers dimensioning in an environment with 3D-modelling.
Computorised planning can be conducted with automatic presentation of niose levels, pressure drop etc.
