Onis Visa POWER CONTAINER: soundproof containerized diesel generators for heavy duty and complex projects
The Onis Visa POWER CONTAINER range is designed for particularly complex and demanding projects, providing a complete containerized diesel generator solution built for intensive, heavy-duty use. Each generating set is fully installed inside a robust soundproofed container and comes as a complete, ready-to-deploy power unit incorporating a comprehensive arrangement of accessories and integrated systems. Both external and internal technical equipment can be customised to project specifications: dust and water ingress filters, high-capacity fuel tanks up to several thousand litres, custom control panels, roof-mounted special radiators and many more options are available. The POWER CONTAINER range achieves sound pressure levels as low as 50 dB(A) at 7 metres, making it suitable for noise-sensitive environments and urban installations. All containers can be silenced to customer-defined residual noise thresholds on request.

Standard Equipment
WALL AND ROOF INSULATION:
- Walls and roof insulated with rock wool or fibrous materials combined with galvanised stretched sheet metal protection, achieving Euroclass A1 fire reaction rating.
- Insulation thickness defined according to the required residual noise level; all materials are certified fire-reaction Euroclass A1.
SOUND INSULATION:
The soundproofing system meets the residual noise thresholds defined by Onis Visa standards, ranging from 65 dB(A) to 75 dB(A) at 7 metres as standard. Custom low-noise versions silenced below these levels are available and can be engineered to the customer's specific project requirements.
COOLING SYSTEM:
Each containerized diesel generator is cooled by a purpose-designed silent air intake and outlet system, configured to suit the installed engine type, target residual noise level and site-specific variables. For complex installations, silencing panels are sized and positioned to address individual project requirements.
Optional Accessories
- Internal lighting system for safe maintenance access;
- Fire suppression system and gas detection system;
- Ventilation and air conditioning systems, sand and dust filters, motorised dampers;
- RINA, UIC, CSC certification and other project-specific certifications available on request;
- Phonometric tests and noise measurement reports.
