Machine enclosure or Operator cabin, for indoor or outdoor use. Can be fitted with silenced ventilation/cooling/heating, door/window, lighting. Environmental noise barriers & silencers for dust collectors. Soundproofed building contains large axial fans and heating equipment for an underground mine. It is built with thermo-acoustic insulated panels, air intake with silencers/louvers, acoustic doors and an engineered steel structure – all turn-keyed by Silentec, with a noise performance guarantee. Acoustic shroud, over part of an HRSG casing (Heat Recovery Steam Generator). In addition to the vibration isolated acoustic panel envelope, it has a silenced vent system designed to limit the temperature of the casing structure.

Roof mounted noise barrier for a ventilation and air conditioning system. Panel System B is rigid and structural. It resists wind gusts while screwed on long spans. Whilst 24’ is a standard length; it can be ordered longer or cut to size on site. Residential heat pump noise barrier, with wood finishing for aesthetic purposes. Other finishes are also available. Noise treatment for emergency electric generator, with silencers & barrier/absorption panels.

Temporary noise barrier application. Reusable, and fast installation/dismantling. Panel length: 24’ standard, available up to 44’. Wind resistant with long span requiring fewer columns.
