Robust Partner of Industry



DELTA PROSES commissioned Turkey's most prestigious tunnels in İstanbul, Kağıthane - Piyalepaşa and Bomonti - Dolmabahçe tunnels with all electrical and automation systems, Sarıyer - Çayırbaşı tunnel has signed an agreement for the entire electrical and automation works. Turkey's longest and most high-density urban traffic tunnels, using advanced technology equipment and software is controlled. Turkey and Europe in terms of reliability and user comfort of the tunnel between the tunnels is a candidate to take part.
All sub-control systems located within the tunnel, the tunnel Local Control Center and Control Center located in the tunnel can be monitored and controlled via SCADA.
The sub-systems within the tunnel and control systems, the following occurs:
  • Tunnel Ventilation System
  • Tunnel Lighting System
  • LV and MV Power Distribution System
  • UPS and Generator Emergency Power Systems
  • Fire detection and extinguishing system,
  • Camera Monitoring System in and out of the tunnel,
  • Event Detection System
  • Tunnel Traffic Control System
  • Variable speed control signs and traffic lane
  • Variable message signs
  • Vehicle count and classification done,
  • Tunnel radio
  • SOS Emergency Telephone System
  • Tunnel Safety Equipment
  • Meteorological Monitoring Systems
