BMT devices are standard equipped with the ECO digital controller and can be upgraded to the advanced EVO digital controller for expanded functionality and features. Both the ECO and EVO controllers utilize fuzzy logic to assess process data, including operation temperature, chamber size, and other controlled elements. Based on the assessed data, the controller can make continuous adjustments to input values, such as heating intensity or cooling, to optimally regulate internal chamber conditions. With the goal of minimizing the time required to meet set process parameters, devices equipped with either the ECO or EVO controller can quickly ramp up to the exact temperature set point without overshooting. The result is reduced overall cycle time, power consumption, and recovery times after opening the chamber door(s).
