Designed for low horsepower gas fueled, carbureted rich-burn industrial engines.
Microprocessor-based controller with a single set point.
Set point and operation done entirely through the full-color graphic display, enclosure or remote mounted.
Post catalyst, oxygen sensor input for real-time adaptation to changing catalyst performance (post catalyst sensor is optional).
Pre and post catalyst thermocouple input for catalyst over temperature protection (ungrounded Type K thermocouples, optional).
Pre and post catalyst differential temperature displayed.
Separate alarm and shut-down dry-contact relays for flexibility in setup and operation.
High-speed full-authority butterfly fuel control valves for quick response time. (available)
Proportional solenoid fuel control valves for auxiliary fuel control (available)
The AFR-1R is the simplest to use rich-burn engine, single set point air/fuel ratio control system available. The system is designed to maximize the efficiency of a 3-way catalyst by maintaining the proper air/fuel ratio.
Maintaining the correct air/fuel ratio to enhance the performance of your catalytic converter shouldn’t be that hard, and it’s not if you choose the right equipment.
The FW Murphy AFR-1R features a single pre-catalyst set point target to optimize the catalysts performance. And when activating the optional post-catalyst set point target, the AFR-1R monitors the catalyst performance and adjusts the air/fuel ratio to maintain and prolong the catalyst performance.
The system includes the FW Murphy PV450 fullcolor graphical user interface for control functions, monitoring, programming and diagnostic displays.
