Linkageless system uses a burner with individual servos to control fuel and air ratios, thereby providing savings to the end user. Benefits of linkageless systems include higher efficiency: O2 levels may fluctuate but will always return to position of highest fuel and electrical efficiency. In addition, turndown often is improved, resulting in less cycling of the burner. The system communicates via Modbus and reports on all functions. The main module monitors the positions of all fuel- and air-control devices. Any positioning error shuts the burner down safely. It also provides automatic adjustments for ambient air and fuel changes. The FlexFit can be used in new or retrofit applications and fits into existing jackshaft control panels that use supported common flame safeguards.
