The new Visa range of enclosure with rockwool soundattenuating material - available in sizes GV151 and GV 205 - offers innovative features of soundproofing, thermal insulation and improved cooling air flow. 

The soundproof canopies for generating sets are made of galvanized steel and are designed to be internally lined with rock wool, a highly effective solution for noise reduction, achieving acoustic attenuation of up to 30 dBA with 50 mm panels.
 

The sound-absorbing panels used are non-combustible, corrosion-resistant, and designed to ensure long-term durability.

Thanks to its open-cell fibrous structure, rock wool provides excellent acoustic performance, allowing sound waves to be absorbed and attenuated.

In addition to its sound-absorbing properties, the material guarantees high mechanical strength, vapor permeability, water repellence, hygienic safety, and resistance to microbial attack.

Main features and advantages of the new range of soundproof enclosures with rock wool insulation:

• Superior acoustic insulation: the fibrous structure of rock wool traps air, enabling highly effective noise attenuation.
• Safety and resistance: possibility of achieving Class A1 non-combustibility classification, ideal for high-risk industrial applications.
• Design flexibility: standard or custom-built enclosures with internal rock wool lining for optimal noise reduction and enhanced protection of machinery and operators.

Starting from this high-quality canopy range, Visa can offer an even higher level of noise reduction thanks to the following design solutions:

ADDITIONAL HIGH-PERFORMANCE SOLUTIONS FOR EVEN FURTHER NOISE REDUCTION

• Improved airflow management: addition of panels for intake and exhaust air flows.
• Double sealing system to further reduce noise.
• SCR exhaust system with additional silencer.

The result is a technologically advanced enclosure, designed to provide high acoustic comfort, mechanical robustness and long operational life, increasing the overall reliability of the generator set.

The combination of advanced design and high-performance materials makes this new Visa range of canopies one of the most effectively soundproofed solutions on the market, suitable for use in any context, even under the most extreme environmental conditions.
