Compliance Controls Home

Compliance Controls realized the need for a more advanced, cost-effective, flexible, easy-to-install and easy-to-use engine control system tailored to a customers’ specific requirements. A system based upon a proven technology with powerful enhancements prompted by a decade of real-world control system field experience.

Compliance Controls Air-Fuel Control Systems – for Rich-Burn and Lean-Burn spark-ignited natural gas engines – maximize emissions-control and operational efficiency by maintaining the proper air-fuel ratio over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressures.

AFR-1R: Rich Burn Air-Fuel Ratio Control System

The AFR-1R air-fuel ratio control system operates on an auxiliary fuel line, which can be easily isolated for maintenance, analysis or troubleshooting. Just enter a single setpoint target, and the system starts controlling the air-fuel mix. No fine-tuning or tweaking is needed. Streamlined navigation guarantees single-button access to the main functions. This control system was designed for pure simplicity. Learn more.

AFR-9R: Rich Burn Air-Fuel Ratio Control System for Natural Gas Engines

The AFR-9R controller offers nine setpoint targets, based on a combination of three RPM settings and three manifold pressure settings. As your engine's load conditions change, your AFR-9R continues to make sure it is in the best possible operating range. If your site is facing tightening regulations, changes in ambient temperature, big load swings or gas quality/pressure changes, the AFR-9R is the right solution. Simple air-fuel ratio control with more flexibility. Learn more.
