Burner Controller
Sequences ignition, proving and safety interlocks into one supervised start-up.
Servomotors
Product view
Servomotors
Drives the air and gas dampers that hold combustion ratio across the firing range.
The BC-SM actuator positions air and gas dampers to a signal from the burner controller, holding the air/gas ratio correct as firing rate changes. A mechanical position indicator and adjustable cam or electronic curve let the ratio be set and re-checked at commissioning without guesswork.
Features
- •Proportional positioning across the full firing range
- •Visible position indicator
- •Adjustable mechanical cam or electronic characterisation curve
- •Manual override for commissioning
- •Torque suited to damper and butterfly-valve duty

Frequently asked questions
What engineers most often ask when specifying this equipment.
Ionisation probes are simpler and cheaper and work well on stable, well-defined gas flames with a good earth path. UV cells suit larger flames, oil/gas dual-fuel duty and installations where the probe cannot be positioned reliably.
