MEC-R Rich-Burn Air-Fuel Control System

If your business banks on revenues from rich-burn, spark-ignited natural gas-fueled engines equipped with catalytic converters, you face tough challenges every day:

Emissions Control Compliance. Variance by as little as one percent from the stoichiometric air-fuel ratio – the ratio at which all fuel is oxidized in engine combustion – will keep your catalytic converter from doing its job.
Troubleshooting & Maintenance. Engine misfires, ashed catalysts, overheating: these and other glitches not only impair engine performance and shorten your equipment’s life span. They can also cost you plenty. Take one example. The unburned fuel coughed into your exhaust stream by a misfiring cylinder can cause a hot catalyst to burst into flame.
Operational Issues. In any competitive arena, your business suffers when you’re not getting the benefits of today’s most advanced technologies, and tomorrow’s. But keeping up with technology can be costly – in dollars, time, headaches and hassles. And who can afford to keep rocket scientists on board to run engines day-to-day?

Compliance Controls has the ideal solution: The MEC-R Rich-Burn Air-Fuel Control System.™

The Best. Bar None.

The MEC-R controls rich-burn, natural gas-fueled engines – maximizing the efficiency of a three-way catalyst by maintaining the proper air-fuel ratio over varying engine loads, speeds, fuel quality, ambient temperatures and barometric pressures.

And the MEC-R works without operator intervention.

Easy to install, even easier to use, and equipped with a comprehensive 44-fault on-board diagnostics and troubleshooting system, the Windows-based MEC-R redefines the state-of-the-art – in hardware, microprocessor power, control system software, operator interface options, adaptability to variable engine conditions, software upgradeability, you name it.

Typical Configuration (Dual-Valve, Full Authority)

Dollars & Sense. Continuous emissions control. Improved engine performance. Longer, more trouble-free equipment service-life. Fail-safe troubleshooting. Fast, easy installation. Easy, user-friendly operation, with minimal training. Network compatibility (RS485 or CAN link), with high-speed data transfer. Powerful smart-system features and benefits you won’t find anywhere else. All with the flexibility to tailor solutions to your specific current and future wants and needs.

Business owners, financial officers, engineers, IT and operations managers can all agree: the Compliance Controls MEC-R Rich-Burn Air-Fuel Control System is simply the best value on the market, bar none.
