Critical infrastructure safety requirements
Modern tunnel projects demand validated life safety systems that meet stringent regulatory standards during fire emergencies. Engineering specifications require documented performance data for longitudinal ventilation solutions.
NOVENCO Building & Industry has engineered tunnel fans for longitudinal ventilation applications since the early 1970s. These tunnel ventilation and smoke control systems address complex specifications for road and rail infrastructure.
These impuls fans and jet fans systems deliver certified performance for engineering documentation and regulatory approval processes.
Technical specifications and features
Technical specifications include:
- Uni-directional or 100% reversible configurations
- Certified smoke control systems rated to 400 °C for 2hrs per EN standards
- Documented efficiency parameters and acoustic performance data
- Precision-engineered deflectors for optimised installation
- Maximum thrust output within constrained installation heights
Based on decades of experience in tunnel ventilation, NOVENCO Building & Industry has developed a space-saving range of rectangular design jet fans. Compared to standard round tunnel jet fans, the height saving is almost 200 mm.
Combined with specially designed aerodynamic deflectors, these height-savers achieve superior system efficiency compared with conventional air deflectors. The reduced tunnel ceiling height delivers substantial construction cost savings over the entire tunnel length.
Our comprehensive services include:
- Complete longitudinal ventilation system design
- Deterministic and probabilistic calculations for risk assessment
- Project-specific performance optimization
- Full testing protocols including FAT (Factory Acceptance Test) and SAT (Site Acceptance Test)
