Compliance Controls AFR-9R: Air Fuel Ratio Controller

Rich Burn Air-Fuel Ratio Control System for Natural Gas Engines

compliance.AFR9Compliance Controls’ AFR-9R air-fuel ratio controller is exactly the right choice. It is pure simplicity at every step, from installation to operation.

The AFR-9R controller is a true load-following controller. It offers nine setpoint targets that can be specifically matched to engine conditions, based on a combination of three RPM settings and three manifold pressure settings. As your engines load conditions change, your AFR-9R continues to make sure it is in the best possible operating range.

Compliance Controls AFR-9R air-fuel ratio controller offers the same simplicity as the AFR-1R model. Non-intrusive installation. Streamlined menu-driven navigation. But with more setpoints, you get even tighter control. It also includes manifold pressure and RPM sensing technology.

If your site is facing tightening regulations, changes in ambient temperature, big load swings or gas quality and gas pressure changes, the AFR-9R is the right choice. It’s simple air-fuel ratio control with more flexibility.
