      LEC1系列燃燒器控制器(SIEMENS)

      LEC1系列燃燒器控制器(SIEMENS)
      產品說明:

      Control unit for double or multiflame supervision of oil, gas or forced draft oil / gas burners of any fuel throughput, suited for continuous or intermittent operation.

      The LEC1... is designed for the fully automatic startup and supervision of forced draft burners with which the flame supervision should or must be carried out by separate flame safeguards, e.g. with

      • Dual supervision
      of the main flame or of the pilot and main flame by 2 identical or different detectors.
      • Supervision of forced draft oil / gas burners
      with different types of detectors depending on the selected operating mode.
      • Multiflame supervision

      that is, central and simultaneous control of the startup and supervision sequence for several burners the flames of which must be individually supervised by one or 2 flame safeguards each.
