S2 Mercor tunnel

Mercor delivered to the facility devices for the automation system for tunnel ventilation based on the mcr OMEGA pro power supply units. Tunnel ventilation is a complex technology requiring compliance with, among others: criteria such as exhaust gas level control or adequate visibility for drivers. A system of sensors located in the tunnel transmits information about their current status to MERCOR devices.

26 mcr OMEGA pro control panels are responsible for activating the elements used to improve air quality and visibility in the tunnel, which perform various functions depending on their intended use. Ground mounted, located in transformer stations, are responsible for the control and monitoring of exhaust fans, supply fans started with inverters and jet fans, for which soft starters are the starting devices.

In the tunnel part, in each of the emergency passages, control panels composed of, among others, made of ABB components, controlling 152 dampers located along the tunnel, which are activated for air extraction and supply.

Switching the backup power supply for the fire ventilation system takes place in a certified power supply unit manufactured by MERCOR, for the construction of which air circuit breakers of the Emax series were used.

We are proud that being part of this unique project on a national scale, Mercor will take care of the safety of its drivers on a daily basis.

We wish everyone a safe journey.
