SilenGen Soundproofed Shelters

Génératrice Drummond manufactures customized SilenGen soundproofed shelters in compliance with the standards of the Canadian Standards Association (CSA).

The unique design of these shelters allows the reduction of noise levels to 55 dBA.

Consequently, it is possible to install diesel engine generators in areas where regulations require very low noise levels, such as:

  • Residential areas,
  • Data centres located in urban areas,
  • Universities,
  • Near hospitals.

Available in many sizes and tailored to your needs, these shelters also protect generator sets from bad weather to ensure start-up in all conditions, even in hard to reach places.
