Tunnel Fans

Howden’s range of fans for tunnel ventilation has been developed and improved thanks to many years’ experience in the market with multiple brands.

Our axial and jet fan products cover a wide range of performance duties and can be configured as reversible or uni-directional to suit the needs of all tunnel ventilation systems.

Every fan is designed and manufactured to the highest quality standards for assurance of safe and reliable operation in the event of fires and long-term performance. Fans are tested to the most stringent fire safety standards (DIN EN 12101-3 or ISO 27927) to operate at 200ºC/1h or up to 400ºC/2h. Aerodynamic testing of fans ensures performance meets or exceeds all required standards demanded by project specifications.

Our fans can be delivered on a scalable basis including full turnkey and are backed up by a comprehensive aftermarket capability to ensure performance is maximised throughout the life of each operation.

Digital Controls

Digitalisation is improving the way many industries control and optimize their assets. This is also true in transportation tunnels and Howden is a leader in the field.

Fans are fitted with multiple sensors allowing our Howden Uptime platform to seamlessly integrate related performance data. The system combines active inputs, such as temperature, pressure and vibration, with reference parameters from manuals, specifications and maintenance reports. When the data is analysed, it provides a unique foundation for maintaining and enhancing operational excellence.

Digital Controls

Aftermarket

A ventilation system must operate reliable for multiple decades. Keeping fans well maintained and rated for conditions is critical, as some fans operate on a continuous basis and other fans need to respond instantly to emergencies.

Howden offers full lifetime service coverage. We have a permanent presence across every continent with specialist engineers able to ensure reliable performance through expert maintenance and quick resolutions to any unexpected issues.

The range of services on offer support our ventilation equipment as well as fans supplied by other manufacturers.

Our range of services includes:

  • Inspections
  • Testing and training
  • Spare parts and inventory management
  • Repairs and refurbishments
  • Retrofits and performance enhancements
  • Balancing

Services are delivered either on-site or in our workshops depending on the nature of the service and customer requirement.
