Tunnel Ventilation


The integrated drives family for every application

  • The complete and integrated drives family that covers all performance levels. The converters are characterized by maximum flexibility, functionality and engineering efficiency

  • Wide performance range from 0.12 kW to 85 MW

  • Optimally integrated into the automation system with PROFIdrive, PROFIsafe and PROFIenergy

  • Powerful, drive-autonomous safety functions. Shared engineering with just two tools for all drives: SIZER for configuring and Startdrive for parameterizing and commissioning

Benefits in the tunnel

  • System-wide integration of the SINAMICS converters into the overall SIMATIC system enables optimal integration and diagnostics of the ventilation system

Smoke Extraction Motors

Reliable ventilation even at high temperatures

  • Low voltage motors for use in automatic smoke and heat extraction systems according to EN 12101-3

  • Ventilation or extraction under standard conditions, for instance KT -20 ... +40°C

  • Certified smoke extraction motors meet a running time of 120 minutes in each temperature class (200 °C and 300 °C) and therefore provide increased security above the current standard requirements

Benefits in the tunnel

  • In case of fire, Siemens smoke extraction motors can keep the tunnel free of smoke to keep evacuation and access routes clearly visible and to facilitate fire-fighting

  • Siemens smoke extraction motors can even cope with high ambient temperatures safely and, in the event of an accident, reduce the heat loading on the tunnel
