HTS Maxon – Smartfire Intelligent Combustion Control System
Need help selecting your product?
The Honeywell Maxon SMARTFIRE® Intelligent Combustion Control System is an advanced closed-loop platform that optimizes combustion efficiency, safety, and repeatability across industrial burner systems. Combining continuous oxygen trim, real-time combustion monitoring, and intelligent valve actuation, SMARTFIRE® delivers highly accurate fuel-to-air ratio control, reduced emissions, and lower operating costs. Designed to integrate seamlessly with Honeywell Maxon burners and SMARTLINK® valve technology, SMARTFIRE® provides complete digital management of air and fuel delivery in modern thermal process systems.
Features & Benefits
- Continuous, closed-loop fuel-to-air ratio control for optimal combustion efficiency.
- Integrated O2 trim maintains precise excess air across varying process loads and ambient conditions.
- Combines the SMARTFIRE® controller, SMARTLINK® DS actuators, and intelligent valve assemblies into a unified system.
- Reduces setup and commissioning time through automated calibration and digital tuning.
- Built-in diagnostics, data logging, and communication interfaces support predictive maintenance and process optimization.
- Up to 8 channels of control available for multi-burner or zoned applications.
- Designed for integration with existing PLC and SCADA systems via Modbus TCP/IP or RTU protocols.
System Overview
SMARTFIRE® consists of three primary system components:
| Component | Description | Key Features |
|---|---|---|
| SMARTFIRE® Controller | Core combustion control module | Manages all process inputs/outputs, air/fuel ratio, O2 trim, temperature, and safety interlocks. Communicates with field devices via Modbus TCP/IP or RTU. |
| SMARTLINK® DS Actuators | Digital positioners for valves/dampers | Provide precise digital valve control with feedback and diagnostics; eliminate mechanical linkages and manual tuning. |
| O2 Trim Sensor & Analyzer | Real-time oxygen feedback device | Continuously measures flue gas oxygen and adjusts the combustion profile for maximum efficiency and low emissions. |
