Krom schroder BCU370WFEU0D3 88600123 gas burner control unit application

1. Kromschroeder 88600123 BCU370WFEU0D3 automatic gas firing device can be utilized for both directly ignited forced draught burners and those ignited with a pilot burner. 
2. Kromschroeder 88600123 BCU370WFEU0D3 gas burner control box activates the fan and positions the connected butterfly valve in the pre-purge and ignition position.
3. Following pre-purge and burner start-up, the Enable signal is sent to an external controller, which adjusts the butterfly valve according to the required output demand.
4. Post-purge occurs after burner operation ceases.
5. Kromschroder 88600123 BCU370WFEU0D3 control unit monitors gas and air pressure.
6. An optional tightness control function checks valves using an external gas pressure sensor.
7. Programmability through the optical interface and BCSoft software ensures optimal adaptation to specific applications.
8. Adjustable start-up attempts and automatically restart, when activated, ensure high flexibility of burner equipment.
9. The quick-start option allows compliant start-up of forced draught burners without pre-purge after normal shutdown, thus preventing unnecessary air admission into the combustion chamber, and quickly achieving maximum heat output upon temperature demand.
