Noise protection units prevent sound propagationat the very point of origin and protect the operating personnel from intense direct sound.

The Noise Protection Tunnel System HEIN Model : TUS 472 represents the total enclosure of the noise emitter -- in minimal space --

Noise protection tunnels in the field of container movement contribute further
-- as ancillary effect -- to product protection.
They prevent the entry of foreign particles into open containers.

Noise protection
on conveyor systems

The transfer movement of containers in
bottling machines is known to emit
noise values above the mandatory
limits for various reasons.

and TUS 472 European Patent

This system is distinguished by a minimum space requirement and allows --- when open --- total explosure of the bottle conveyor and thus, full access.
A typical example of an application with the Noise Protection Tunneling System HEIN
Model : TUS 472
The tunnel elements that are strung together are preferably layed out longways (up to 3000 mm length).

Noise protection on conveyor systems
Model : HSA

Every HEIN Tunnel System is designed to be absolutely free of obstruction.

That is:
  • the entire conveyor track can be freely accessed from both sides instantly.

  • for conveyor repair work the tunnels do not have to be disassembled - not even partially.
Note:
On a European level, legislation has come into force, the EU "Noise" standard (2003/10/EU) effective from 15-02-2003, to improve industrial impact.
For example, noise protection measures above a noise emission level of 80 dB(A) ("lower threshold value") are required.
