Overview

ETC6100 is an electronic ratio control (ERC) solution for combustion systems, designed to manage single point and multi-element processes with precise fuel-air mixture control. It supports smart system architectures by integrating with IoT frameworks and enabling advanced monitoring and analytics. Its compact footprint supports installation inside burner enclosures for both new and retrofit applications.

Core functions

• Adjusts the fuel-air ratio to optimize combustion performance across single point and multi-element processes
• Controls fuel and air positioning using assigned rotary servomotors to maintain accurate, repeatable ratio control
• Manages multi-curve operation by programming up to four fuel-air ratio profiles to suit different operating conditions
• Coordinates combustion air fan and fuel pump control through dual variable speed drive management, including VFD-based fan speed control
• Performs local modulation using boiler temperature or pressure sensors with two internal PID controllers for integrated control behavior
• Supports integration and interfacing through CANBus wiring architecture, selectable industrial communications, and interfaces to third party flame safeguards

Key technical features

• Up to 10 rotary servomotors can be assigned to address complex applications
• Rotary servomotors positioning accuracy of ±0.1°
• Control of two variable speed drives for combustion air and fuel pump control
• Local modulation using ETC or third party boiler temperature or pressure sensors
• Two internal PID controllers for modulation control
• Up to 4 fuel-air ratio profiles can be programmed
• CANBus communications between controllers, servomotors, displays and peripherals to simplify wiring
• Communications protocol options include RS-485, Profibus and Modbus RTU
• Interfaces to third party flame safeguards for external system connectivity
• Multilingual text or graphical display options available for the user interface 

Options and customization

• Oxygen trim option using a dedicated ETC oxygen probe and interface
• Communications interface selection via RS-485, Profibus or Modbus RTU (as required)
• Multilingual text or graphical display selection for the user interface
• Compatibility with ETC621x expansion modules for boiler water control

Typical applications

• Burner control systems requiring electronic air-fuel ratio control for single point or multi-element combustion management
• Single and dual-fuel boiler applications, including new installations and retrofit integration within burner enclosures
• Low NOx combustion strategies, including flue gas recirculation, and applications using complex or exotic fuels
