DCS ABB A Trusted Partner in Tunel Ventilation in Canada 1 400

The safety and well-being of tunnel users depend on excellent ventilation. With its compact electric drives, ABB helps designers and operators of major infrastructures to meet the major technical challenges.

Ventilate better to protect better

Ventilation systems in tunnels first intend to protect their users' health and safety. Under normal circumstances, ventilation limits the concentration of pollutant emissions from motor vehicles and ensures good visibility. However, ventilation is part of the extinguishing system when a dangerous condition occurs, such as a fire. It removes smoke and heat from the tunnel, maintains escape routes and allows emergency services to access the incident site.

In 1999, a truck accident in the Mont Blanc tunnel caused a major fire. One of the leading causes was an insufficient smoke ventilation system. This unfortunate incident prompted France to inspect all its tunnels over 300 meters and review its safety standards, and many countries followed suit.

ABB meets ventilation challenges in Montreal and Toronto

In Canada, ABB proudly contributes to the safety of the Louis-Hippolyte Lafontaine tunnels in Montreal and the Crosslinx project in Toronto by installing its ACS880-17 and ACS880-37 series drives.

Reliability, an essential ally

Tunnels are critical infrastructures that provide essential transport connections for the local, national, and even international economy. Therefore, they must be safe and available, always. Controlling operational risks, such as ventilation failure in an emergency, must be supported by reliable facilities.

The technical challenges of ventilation

The tunnel ventilation system presents numerous technical challenges, including rapid braking and reversing direction in an emergency. ABB drives, such as our ACS880-17 ultra-low harmonic and regenerative drives, can stop and restart fans in less than 10 seconds feeding braking energy back to the grid - a blazing speed. Furthermore, these compact drives are ideal for tight spaces, which is often the case in tunnel infrastructure.

Global guidelines and standards for tunnel fans specify the time and temperature at which they must operate under extreme conditions. Particular attention is paid to acceleration and braking times. For example, motors must be tested in accordance with EN 12101-3, which is considered the most demanding standard for smoke extraction.

Promoting energy efficiency

Ventilation systems in tunnels can be incredibly energy-intensive and expensive. Ensuring the energy efficiency of such projects is a priority. Adjusting the speed of a fan according to demand is a sensible use of energy. ABB drives, equipped with high-efficiency motors (up to IE5), control the fans' speed according to the tunnel's air pollution.

Our variable speed drives can generally reduce energy consumption by 20 to 60% compared to fans operating at nominal speed.

They are also equipped with temperature monitoring, overload, overcurrent, under/overvoltage and other protections and warnings to prevent control failures in ventilation systems. In addition to these features, the drive contains a fire override mode, which promotes safe evacuation in the event of a fire, and a real-time clock, which indicates the incidence of events by tracking failures. Our ACS880-37 ultra-low harmonics (ULH) drives guarantee the quality of power supply on the tunnel network, ensuring the reliability of the electrical system and equipment – the electrical harmonics are taken to a minimum of 3%, and voltage drops over long tunnel cables are compensated with a drive-based voltage boost feature, so ventilation runs smoothly 24/7.

Security and efficiency

ABB's variable speed drives combined with accessible customer service help designers and operators of large infrastructure projects to ensure the safety and well-being of their users while improving the energy efficiency of their infrastructure.

DCS Lafert Formally Introduces New Plant in San Dona di Piave 1 400x275

The new production plant is officially in operation after its formal unveiling at Lafert’s 60th anniversity celebrations in San Donà di Piave, Italy, close to the historic headquarters. 

The 130 000 sq foot plant was developed to increase production capacity and meet the growing demand for IE5 Super Premium Efficiency motors, while also providing new storage areas for raw materials and finished products. In this plant alone, Lafert is able to produce up to 1400 pieces per day and can ship 4-5 international containers per week thanks to the internal customs area. 

The project began in September 2020 with the aim of building a brand-new manufacturing plant to produce high efficiency permanent magnet motors, specifically intended for pumping applications. The plant was designed and built with extensive automated production capabilities including fully automated production lines. Today the plant employs 50 operators who have been carefully trained to work in synergy with the production lines. The plant delivers maximum comfort in the working conditions of the operators in terms of light, space, services, and other factors that affect the well-being of employees.

DCS New LUTZE DRIVEFLEX and MOTIONFLEX VFD Cables from Automation Direct 1 400x275

AutomationDirect has added new LUTZE DRIVEFLEX® and MOTIONFLEX® variable frequency drive cables which provide supreme protection against electromagnetic interference (EMI).

These cables are available in 18 to 8 AWG sizes and include four black conductors with a green/yellow ground conductor of the same gauge. Each conductor is labeled for easy identification and is covered in a cross-linked Polyethylene (XLPE) insulation (type XHHW-2) that is oil and sun resistant, suitable for dry, damp, or wet locations, and approved for direct burial.

The DRIVEFLEX series has a black PVC outer jacket ideal for stationary applications, while the MOTIONFLEX series has a black thermoplastic elastomer (TPE) outer jacket designed for continuous motion applications. Both cables are tray cable-exposed run rated (TCER) for use in cable trays with or without conduit, which can significantly reduce installation costs.

The new DRIVEFLEX series cable starts at $2.58 /ft. and the MOTIONFLEX series cable starts at $3.67 /ft.  Both cables are made in the USA and can be ordered cut to length in 1-foot increments with a 10ft minimum.
