LGB21系列燃气燃烧器控制器

LGB21系列燃气燃烧器控制器
产品说明:

The LGB... burner controls are used for the startup and supervision of single- or 2-stage gas or gas / oil burners in intermittent operation. Depending on the type of burner control used, the flame is supervised either by an ionization probe, a blue-flame detector QRC1... for forced draft gas / oil burners, or a UV detector QRA... (with auxiliary unit AGQ1...A27).

In connection with the respective adapters, the LGB... burner controls replace their predecessor types LFI7... and LFM1... (also refer to ?Replacement types under Ordering).

  • Automatic forced draft burners for gaseous fuels to EN 676

  • Gas burner controls to EN 298

  • Undervoltage detection

  • Air pressure supervision with functional check of the air pressure monitor during startup and operation

  • Electrical remote reset facility

  • LGB41... for use with atmospheric gas burners
