MCON Nitro measures H2 level in the furnace and calculates characteristic nitriding number Kn. Depending on the difference between measured Kn and desired Kn (setpoint), NH3 flow is increased or decreased which directly affects dissolution of ammonia and thus H2 level into furnace and Kn. In addition, the device also controls the temperature in the furnace with heating or heating/cooling outputs. N2 and Endogas flows are set points that are used to drive mass flow controllers while NH3 flow is controlled with a PID control algorithm in which process value is Kn and manipulation value is scaled to NH3 flow.

The MCON Nitro is a measuring and control system for exact furnace atmosphere-control in nitriding- or nitrocarburizing processes. The 99 program controls of process-temperature and KN -values, with free eligible program time tracks and analogous outputs for NH3- N2- Endogas CO2, by mass flow controls enable an exact control of gas-nitriding processes. A controlled N2- thinning of the Nitriding atmosphere is possible. By use of the initial gas, it is possible to reduce the complete treatment time.
