TUNNEL & METRO FANS

Fans for Road, Railway & Metro Tunnels

For over fifty years, TLT-Turbo has developed first-of-their-kind, fine-tuned, and advanced ventilation systems for road, railway and metro tunnels. TLT-Turbo focuses on the system as a whole to offer you a safer ventilation system with high availability and lower maintenance costs over the total system life cycle. Experience, engineering and R&D lead to the highest product quality while our field-proven technology results in high end customized solutions designed specifically to the operational requirements of your project. TLT-Turbo’s ventilation system optimization provides high energy savings leading to lower lifetime operational costs and results in lower noise emissions.

The new MoJet®

In cooperation with Mosen Ltd. we have reimagined the traditional jet fan. The innovative design of the MoJet® is aerodynamic and efficient, resulting in more thrust without any additional power.

A Single-Source Solution

We offer a single-source solution for the design, manufacturing and installation of tunnel and metro ventilation. This achieves a significantly higher degree of safety as ventilation and smoke extraction systems are combined and complemented by intelligent monitoring and control systems. Our approach also includes a focus on optimization for more efficient energy consumption and noise abatement to ensure an ideal environment within the tunnel. This holistic approach keeps your initial investment and future operating costs at a minimum.

Features of TLT-Turbo’s Tunnel & Metro Ventilation Solutions

  • Reduced Tunnel Ventilation System power consumption
  • Reduced total cost of ownership
  • Sustainable environmental protection
  • Shorter installation and work timelines
  • Simplified order process for EPCs with a single point of contact

Products Range

Smoke Extract Jet FansThe TLT-Turbo Jet Fan generates thrust to accelerate the in-tunnel air flow velocity. It is designed for tunnel operation at exceptionally challenging environmental requirements as well as emergency smoke extraction at extremely high temperatures.

MoJet®The reversible TLT-Turbo MoJet® increases the in-tunnel air flow velocity by up to 50% compared to conventional Jet Fans. To achieve this significant improvement in performance, the MoJet® uses shaped nozzles which turn the jet flow away from the tunnel soffit and walls.

Smoke Extract Tunnel & Metro FansThe TLT-Turbo Tunnel & Metro Fan generates pressure and volume flow at highest efficiencies and product life times. It is designed for tunnel operation at exceptionally challenging environmental requirements as well as emergency smoke extraction at extremely high temperatures.

Variable Pitch Tunnel & Metro FansThe TLT-Turbo Variable Pitch Tunnel & Metro Fan generates pressure and volume flow at highest efficiencies and product life times. Adjustment of the blade angle during operation enables you to cover a wide range of operation points and ventilation scenarios always at the optimum efficiency. It is designed for tunnel operation at exceptionally challenging environmental requirements as well as emergency smoke extraction at extremely high temperatures.

Service & MaintenanceTLT-Turbo provides you with all relevant services around fans and ventilation systems for the whole product life cycle, e.g. site management, maintenance, trouble shooting and many more. We offer additional support during the tunnel design phase to optimize the complete system to guarantee reliable and safe functionality with highest efficiency.

Construction FansThe TLT-Turbo Construction Fan provides the construction site continuously and reliable with fresh air supply or removes consumed air. Due to the modular design the fan performance is scalable and thereby adjustable to tunneling progress. It is designed for operation under exceptionally rough environmental conditions under ground and on site.

Customized FansTLT-Turbo has specialist staff in all relevant technical fields like aeroaccoustics, material science and mechanical engineering. We design fans tailored exactly to your special demands, e.g. overpressure fans, super high temperature fans for 600 °C and above or exceptionally large fans.

Highest Safety & Efficiency Levels

In closed systems, such a tunnel, the extraction of hazardous gases and smoke, in the event of a fire or other catastrophic event, is of paramount important. It is crucial to keep all areas outside of the immediate fire zone as well as exit routes clear of smoke. TLT-Turbo is your partner for smoke extraction and safety with high temperature tested fans.

Reduced power demand and energy consumption supports environmental protection and compliance with governmental regulations and laws linked to CO2 limits. Customized system design and efficient operation modes improve ventilation conditions and create high quality air for the comfort of passengers and staff.

Client Support Services

We provide support at every point of your ventilation system lifecycle. We offer planning and design support at the start of your project to ensure that the final system meets your precise requirements and meets every safety standard. This is followed by manufacturing, transport, installation supervision, commissioning and aftersales services. We take aerodynamic acceptance measures to ensure that the system is functioning optimally and safely. TLT-Turbo also offers reconstruction and optimization of existing systems.
