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 Siemens SIRIUS Controls Ensures Cold Beer 1 400

Breweries are known for transforming malt, hops, and yeast into beer in gleaming brewing kettles and large fermentation tanks linked by numerous pipes.

Over the centuries, the equipment for mashing, lautering, boiling, and fermenting beer according to carefully guarded recipes has been steadily perfected.

 

The chiller is the heart of the brewery

One of the most important parts of the brewery, and perhaps the least visible, is the chiller. The fermentation temperature of the beer is crucial, which means that the heat generated by the yeast fermentation must be carefully controlled by the chiller.

If the beer ferments at too high a temperature, the yeast can produce a variety of undesirable aromas that ruin the beer.

According to Justin Thomas, President of G&D Chillers, based in Oregon

"The chiller is the heart of the brewery. Owners invest not only a lot of money in the brewery and brewing equipment, but also a great deal of time in the production of beer. But if the chiller fails, all that goes out the window."

Partnerships to keep pace with growth

Thomas says that growth at G&D Chillers has been exponential over the past 15 years. To continue this rate of success, the company had to look for new ways to meet customer demands for reliable, state-of-the-art chiller options.

For example, G&D Chillers recently teamed up with Siemens and the global distribution and supply chain solutions company WESCO to meet these needs and stay ahead of the competition. "We're still a small manufacturing company, but big enough to produce some technically advanced equipment," says Thomas. "We've always been service-oriented and always stood by our equipment, no matter what the problem. We get the same kind of support and service from Siemens that we give to our own customers."

Nationwide Equipment NetworkWhat’s the secret to providing superior service and staying competitive in a changing market? Well, you might learn something from ALTA Refrigeration’s experience. Over ten years, it transformed itself from a custom engineering services company into a scalable industrial equipment manufacturer, using an edge-oriented control architecture to efficiently manage a growing installed base.

 Originally started in 1975 as Industrial Refrigeration Services, ALTA has been designing and installing refrigeration systems across the United States for more than 45 years. And for a long time, they were large, custom-designed systems that used a central machine room to deliver refrigerant to various facility areas through long, overhead piping runs.

International Application by PILZWhen the Swiss engineering company Peter Huber AG won the order to upgrade and convert the control and safety technology on manual-feed bending machines - to include an additional sheet metal feed via robot - alongside the requirements for economy, flexibility and efficiency there was also one key condition in the requirement specification: wherever possible, the envisaged solution should continue to use the existing controllers.

As cooperation between human, robot and machine presents a complex challenge not only in control terms but also regarding safety, an innovative solution was sought. Peter Huber found it in the modular safety relay myPNOZ.
