TLT-Turbo Secures Ventilation Works for Swiss Baregg Tunnel Project

TLT-Turbo (GmbH), a leading supplier of ventilation equipment and systems has received a contract to provide longitudinal ventilation and escape route ventilation for the Baregg Tunnel project through a call for tender by the Swiss Federal Roads Office, ASTRA, based in Zofingen, Switzerland.

The scope of TLT-Turbo’s delivery on the project includes 16 stainless steel, dual-speed jet fans. The jet fans will meet the project’s temperature requirement of 250 °C/2 h. The contract also includes the supply of an extensive array of services including project management, documentation of performance and technical specifications, inspections, QA, testing, training of operating personnel and future maintenance. The order is currently being processed with completion of the installation expected by January 2024.

The Baregg tunnel and the Neuenhof covering are part of Switzerland’s N01 route, located between the exits and entrances of Baden-West and Wettingen. This section is known as one of the busiest sections of the Swiss national road network.

TLT-Turbo Head of Tunnel and Metro division, Jürgen Steltmann, said: “We scoped out this project by starting with a dimensional survey and inspection of the existing tunnel structure. This will be followed by planning, fabrication, factory tests and finally delivery and installation. We are confident that our approach will result in a ventilation solution that meets the requirements of the Baregg Tunnel project and ensures and safe environment for commuters.”

TLT-Turbo has over 100 years of experience in ventilation technology and has been developing, manufacturing, and constructing fans and ventilation systems for more than 40 years. This extensive experience has been consistently incorporated into the development of their tunnel ventilation systems.

According to Steltmann, to ensure a safe environment inside tunnels, TLT-Turbo’s foremost consideration is smoke. “In an emergency, smoke is one of the major hazards for people in an underground tunnel. Our ventilation systems provide clear visibility for escape routes. In case of fire, our Metro and Tunnel fans provide smoke free emergency exit routes.”

“Our other key considerations are quality, noise abatement and energy efficiency. Our fans are tested according to EN 12101-3 give tunnel operators peace of mind that they are receiving ventilation equipment that meets their specifications and is of the highest quality. From there, TLT-Turbo combines specially selected materials, highly heat-resistant motors and design precision to blend quality assurance with the highest economic efficiency,” Steltmann explains.

The aerodynamic features of TLT-Turbo’s Jet Fan range guarantee low power consumption and installation costs. They also help to keep the acoustic noise low. These fans may be used in tunnel sections as jet fans with free inlet and outlet and as axial fans in ducted installations. The success story of these fans started in the early 1970’s in the Alps and several important Alptransit-routes have been equipped with TLT-Turbo tunnel fans since then – including ventilation for the longest railway tunnel worldwide in the Gotthard Base Tunnel.

“Our track record combined with the fact we have well-trained, experienced staff who collaborate with leading international consultants to ensure that we meet expected international standards are what have made TLT-Turbo not just a supplier, but a preferred tunnel and metro ventilation partner renowned for redefining ventilation quality and performance,” Steltmann concludes.

TLT-Turbo GmbH Announces Contract for Wuhan Sinter Project

TLT-Turbo GmbH, global ventilation fans and systems manufacturer, today announced its success in winning a contract for the supply of Sinter fans, including complete drive system, to Baosteel for the Wuhan Sinter Project. The announcement comes amid the COVID-19 global health crisis and further indicates improving business conditions in Wuhan.

TLT-Turbo has secured a contract together with consortium partner, TMEIC (Toshiba Mitsubishi-Electric Industrial Systems Corporation) for the supply of two complete fan systems to Baosteel. Headquartered in Shanghai, China, Baosteel is globally recognised as one of the most competitive iron and steel companies with the highest level of modernization in China.

TLT-Turbo’s delivery on the project will include the supply of two sinter waste gas fans as well as the accompanying drive motors, frequency converters, transformers, switch gears and control panels. TLT-Turbo will also fulfil the role of consortium leader for the project and will take the lead on commissioning and final installation of the fan systems.

“This newly secured contract adds to the growing list of projects that TLT-Turbo has been a part of in China recently – each of which reflects our excellent teamwork and long-term success,” says Ma Le, TLT-Turbo Sales Representative based in the region.

Ma Le adds that this is the fourth contract that TLT-Turbo has won since establishing a working relationship with Baosteel in 2013. Since 2013, TLT-Turbo has delivered a total of eight sinter fans to Baosteel – one of which is the largest operational sinter fan in the world.

“The success of this relationship is built completely on teamwork. The fact that Bao Steel always returns to TLT-Turbo to order our fans also speaks highly of our commitment of quality. The resilience shown by the TLT-Turbo global team is evident in their continued success in securing contracts in this region,” adds Ralph Mansius, TLT-Turbo GmbH Sales Liaison.

A Growing Presence in China

In total, TLT-Turbo has won contracts for 18 Sinter Fans since entering the Sinter market in China in 2012. Aside from their continued success with Baosteel, TLT-Turbo also signed an additional two contracts in China’s sinter market this year.

Another notable success coming out of the region is the continued business in the CDQ (Coke Dry Quenching) market. In 2020, TLT-Turbo has won contracts for a total of 10 CDQ Fans. Says Mansius: “This proves that we are a market leader in our field – and that we are committed to working together as a global team to keep up momentum throughout the COVID-19 crisis.”

Enduring Through the COVID-19 Crisis

Ma Le acknowledges that with the COVID-19 crisis still evolving in all parts of the world, it is to be expected that some orders might be coming in slower than usual. “Businesses across the world will all be bracing for its long-term effects. However, we strongly believe that through the combined efforts of the regional TLT-Turbo teams across the world, we will be able to endure through this crisis and for long after it has passed. We are sincerely thankful to every member of the TLT-Turbo global team for the part they have played in our continued success and resilience. We have all risen to the challenge of temporarily changing how we do things – but this is just another example of Ventilation Redefined.”
