Established over 70 years ago, the Witt Group has expanded into one of the world‘s premier manufacturers of industr ial fans. With manufacturing facilities in Germany, the UK, and Switzerland, JVs in India and China and licensed manufacturing in Canada, Japan, Korea and Indonesia, in addition to a network of agents, the Group is able to supply products throughout the world.
Over the past 40 years, the Witt Group has added Tunnel Ventilation Systems to its range of centrifugal and axial-flow fans. Alongside a range of jet fans, the Group has researched and developed a number of systems that can be used for ventilating tunnels.
Witt Group HQ, Hamburg, Germany
Precise, quality engineering has enabled the Witt Group to establish itself as one of the market leaders in tunnel ventilation systems. The Group is able to conduct the whole process from system design to installation, commissioning, staff training and also service and maintenance.
•Tunnel Jet Fan •Axial – Flow Fan •Banana Jet ® Fan
Working to DIN EN ISO 9001 quality systems, we can ensure that the product quoted is the same as the product supplied, with regards to performance, noise and other characteristics.
Pictured are a number of products used for tunnel ventilation systems:
With a reference list of over 500 projects, including many major contracts such as the renovation of many stations for the RATP in Paris, the Palm Jumeirah Tunnel in Dubai, the XiangAn Tunnel in China and the renovation program of the three old Elbtunnel tubes in Germany, WITT&SOHN AG can call on much experience and technical knowledge to design world-class systems.

WITT&SOHN AG is renowned for its range of axial-flow fans, which are installed in tunnels world-wide. The range of fans is shown below:
Axial – Flow Fans are commonly used in shafts for tunnel ventilation or for exhaust fumes / smoke from the tunnel.
Axial-Flow Fans Axial-Flow Fans
Inlet Size : Casing Thickness :
Volume : Pressure :
Fire Rating : Impeller Material :
Casing Material :
400mm – 4000mm 4mm – 16mm Up to 2,000,000m3/h Up to 7,000Pa Up to 700 oC, acc. EN12101-3 Corrosion resistant cast aluminium, steel, special alloys. Steel, aluminium. Special alloys
Axial-Flow fans as shown on the left are installed in wind tunnels of aerodynamic testing facilities.
Possible accessories & services:
WITT&SOHN AG manufactures large Axial-Flow fans for wind tunnels
• dampers • frequency converters • silencers • performance
testing acc. to ISO or AMCA standards
• impeller diameter 4000mm • and shaft power of about 2,0
MW.
• installation • supervision •commissioning • maintenance
up to 4000mm up to 4000mm up to 2000 kW up to 2000 kW
Testing A comprehensive testing procedure ensures that our products meet the required specifications. WITT&SOHN AG has modern test facilities including a heat test chamber. All tests can be certified by nominated bodies such as GL & TÜV.
Standard Accessories A standard range of accessories is offered with all fans, these include: • Mounting structures • Vibration attenuators • Protection grills
Special Accessories In addition to standard accessories, a number of additional options are also available, these include:
• Bearing temperature thermistors (PTC) • Bearing temperature resistors (Pt100) • Space heaters • Certified calculation for mounting structure • Anchor Bolts in grade 1.4401 (stainless steel) • Anchor Bolts in grade 1.4529 (stainless steel) • Safety switch
Quality Assured Performance Jet fans can be tested according to ISO 13350 and all axial-flow fans according to ISO 5801. Additionally, all fans must pass the factory routine test before delivery. Jet fans are tested and certified according to EN12101-3 (F200, F300 and F400)
• Vibration control sensors • Safety wires (material: 1.4401)
• Halfenscrews in 1.4529 • Safety chains 1.4571 • Terminal box 400°C/2h • Vibration control sensors • Service switch in IP65 • Temperature Sensor • Outlet Guide Vanes
• Fewer jet fans, lower investment costs for fans • Lower power consumption, lower investment costs
for the electrical system, especially cabling. • If niches are required, then they can be smaller
and shorter, lower civil construction costs. • Lower operational cost because of reduced
power consumption and fewer fans to be maintained
• Less turbulence of stratified smoke layer at the ceiling

WITT&SOHN AG has developed the patented „Banana Jet®“ Depending on the tunnel characteristics the Banana Jet ® generates 20-50% more effective thrust than a traditional jet fan of the same size. The Banana Jet® fan reduces the costs for new tunnel ventilation systems and enables tunnel system upgrades (due to increased traffic load or new fire rules) with lower costs.
Banana Jet ®
Traditional Jet
Banana Jet® reduces tunnel installation loss factors
A significant part of the airflow of a standard jet fan sticks to the ceiling and so the transferred impulse is significantly reduced. To take this effect into account several tunnel installation loss factors (Kempf-Factor etc.) have to be applied.
The Banana Jet ® with the bent outlet airflow directs the impulse jet slightly towards the centre of the tunnel, therefore frictional losses due to swirls at the ceiling are negligible. So with Banana Jet ® tunnel installation loss factors such as the Kempf-Factor can be ignored in most of the cases.
Banana Jet® benefits
This problem has in the past been overcome by the use of Saccardo nozzles, where it was possible to blow air into the tunnel with a small angle downwards. As an extension of the Saccardo nozzle solution the Banana Jet ® was developed to be used where Saccardo nozzles are not practical.
