This analysis controlled injection system measures the NO–concentration in the waste gas. Based on this measurement the amount of reactant to be injected into the waste gas channel is calculated. The NO-concentration for this closed loop control is continuously measured after the SCR-catalyst. (The emission monitoring values are updated every five minutes.) That makes it possible to reach very low exhaust pollution standards.
The measuring system and dosing unit make part of the same control system. The cost and time for installation and commissioning are reduced to a minimum.
In order to adapt the system to the varying needs, different options are available. All options can be simply integrated into the standard system. It is also possible to upgrade an existing standard system.

ACIS closed-loop system continuously monitors actual post-catalyst NOx emissions and automatically adjusts reactant injection to ensure compliance whether you’re running a base-load or load-following application from idle to 100% rated load.
Comfort in knowing that continuous, ongoing compliance, and maximum efficiency in reactant use–via an incredibly user-friendly monitoring and control system. Plus, with features like remote monitoring and troubleshooting, ACIS cuts man-hours required for SCR operations.
