LE DIFESE® PLATFORM SOUND-ABSORBER (PSA)

Railway to Silence.

A powerful sound-absorber based on linear PVC panels (PSA_P160, PSA_S125) or pyramidal shaped PC panels (PSA_WALL) that have been developed to protect passengers and local residents from excessive noise from trains slowing down .

A railway station tends to be a polluted and noisy environment due to brake dust, rust and aggressive substances like oils.

Thanks to large perforations in the panel surface, brake dust can partially be stored inside the acoustic panel and will eventually be drained back into the railway track.

The relatively flexible shell resists potential impact from shooting ballast (stones) and the sound absorber can easily be exchanged if needed.

No need for grounding since plastic panels are 100% non conductive matter.

The panels are firmly housed in galvanized steel brackets, resisting severe dynamic loadings. Panels and brackets are firmly secured by strong-duty couplings.

An expansion gap is provided between each panel, allowing it to expand or shrink.

LE DIFESE® PLATFORM meets the highest standards:

EN1793-1:2017, EN1793-5:2016, EN16272-3-1:2012, EN1794-1:2018, EN1794-2:2011, ISO 9001, EN14389, EN14388

LE DIFESE® platform sound-absorber is beneficiary in many ways: 

resistant: ballast stones, ammonia, gasoline, oil, rust.
large perforations: partial storage of brake dust
corrosion proof + grounding-free: up-cycled and recyclable plastic components
light-weight: easy-handling
smooth surface: dirt-repellent, anti graffiti
skin: mass colored, UV-resistant
