Depending on the requirements, silencer-splitter sound insulation for noise control is installed in the inlet air and/or exhaust air openings of the cooling tower according to the absorption damping principle. The splitters with inlet and outlet profiles can be manufactured from galvanised steel profiles or as an aluminium frame construction. A perforated sheet cover is installed to protect the mineral fibre filling. A sound-transparent PE film prevents moisture from penetrating into the sound-absorbing material.
The splitter thickness, spacing and depth are variable and are designed exactly according to the permissible acoustic emission.
