Safety and security

Made for year-round service in all climates, galvanealed steel,  stainless, aluminum or architecturally matched siding finish, weather-proof units can be built to withstand temperature extremes (-40˚C to +50˚C), resist hurricane winds and earthquakes, and protect from theft, vandalism and other attempts at sabotage or acts of destruction.

A sound investment

Perhaps no other category of housing requires a more focused attention to noise reduction than gensets.

SonoShield Walk-in

Recessed on three sides, this attenuated walk-in testifies to its sound proofing and passes the supreme test against reverberation.
It is also subject to tunneling winds, temperature variations from -40˚C to +50˚C, rain, sleet and snow storms.


The Vibra-Sil sound attenuation expertise can provide virtually noise-free installations.

In the field of sound, we have developed attenuation that, to our knowledge and that of our clients, surpasses attenuation limits for genset housings, achieving noise levels to  45 dBA, at 5 meters (15 ft.) on the entire perimeter of the enclosure —and we are working hard on improving that further.
