A linkageless control system uses a burner with individual servos to control fuel and air ratios, and provide more savings to the end user. This technology can cut boiler room costs and solve end-user headaches. Here are three reasons to choose linkageless controls:
- Higher efficiency: O2 levels may fluctuate, but will always return to position of highest fuel and electrical efficiency. In addition, turndown is often improved resulting in less cycling of the burner.
- Monitoring and communication: 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.
- Automatic adjustments for ambient air and fuel changes: Linkage systems can cause major problems for technicians. Once all the linkage is set, the ambient air density may change, throwing the system off. In addition, instead of system readjustment every time there is a fuel switch, the positions of all servos are programmed and independent. This means that the system adjusts automatically to fuel/air ratio changes as well as fuel changes.
In a world of high electric and fuel costs, this technology is indispensable to the modern boiler room.
Our Solution: The Preferred FlexFit Linkageless Controller can be used in new installations OR be easily retrofitted into existing jackshaft control panels that use supported common flame safe guards.
