Montreal’s Transit History
Public transport has been around in the city of Montreal for over 150 years, first introduced on November 27th, 1861 with the first tramway pulled by horses. Throughout the years, the Société des Transports de Montréal – STM has always fulfilled its mission; provide Montrealers with an efficient, reliable, and affordable collective transport service. It wasn’t until 1960 that a subway/metro system project was put in place, by then mayor Jean Drapeau, and construction began soon after for a total cost of 213 million dollars.
In 2020, most of the installations are over 50 years old and require maintenance, repairs, or simply a full replacement. Some of the dampers present in the Montreal metro system were outdated and did not meet the requirements put in place by recent administrations. They were noisy, unsafe, hard to maintain, and some of the parts were just not available anymore. This was the case for the dampers at multiple stations, they had no other choice but to replace what had been installed many years ago.
The STM and AQC
Aireau Qualité Controle (AQC) worked in collaboration with the STM to install the High-Pressure Stainless-Steel Industrial Dampers. AQC designed dampers that met the stringent requirements specified by the STM for the replacement of the old equipment. With the double sealed gasket design, considered as an Ultra-Low Leakage system per AMCA, the single piece transmission axel (with D shaped ends), as well as the high-end material used, allows it to be an exceptional product. Its performance and ease of maintenance makes it a top product for all subway systems throughout North America.
Our Advantages
Dampers have evolved over the last 50 years and our high-pressure, stainless-steel damper is at the forefront of the technological advancements in the field. To assure the highest quality and results of our products, AQC sent the dampers to AMCA facilities in Chicago and put them to the test. As expected, our dampers came back having gone through AMCA’s tests with flying colors. Our dampers are certified 400-D-18 for air volume control and can withstand temperatures up to 752oF (400oC).
We are now in over 12 subway stations on the Island of Montreal, in various tunnels, and are working on many other projects.
