Altronic's AFR-500 Advanced Air-Fuel Control System is a scalable, reliable and cost-effective solution for stationary gas engines.
It can be used on carbureted engines in single or dual regulator configurations, and is designed to be easily installed in new or existing installations. The AFR-500 module operates using a UEGO exhaust sensor and offers precise control of Altronic EPC-series stepper motor-based control valves, the AGV-5 fuel control actuator, and other third-party 4-20mA-compatible devices. The system is compatible with Ethernet and ModBus TCP, and can be accessed and configured via a web browser or PC. The AFR-500 is suitable for use in hazardous areas.
