We design and erect soundproofed containers for generating sets and cogenerators, single-block shelters for switchboards and electricity transformers, soundproofed booths for control rooms. Each container can be supplied with ventilation, air-conditioning, fire-fighting and alarm devices. Some of our shelters are in overpressure with inert atmosphere, for preservation of electric motors of great size in different environmental conditions, like offshore in the North Sea or in the desert of Saudi Arabia, from -48°C of Siberia to +50°C of Qatar.
