Steam Turbine Governors

The Si-TEC BDG and Si-TEC Xtend ADG are steam turbine controls, specifically designed for mechanical drive applications (i.e. pumps, fans, shredders, mills, etc.). These controllers offer optimum steam turbine performance during transient and steady state conditions, utilizing their wide range of control speed PID’s.  

The Si-TEC BDG (Basic Digital Governor) design is based on the very successful Si-TEC Xtend ADG steam turbine controller. The compact design, user friendly interface, onboard data logging and wide range of PIDs makes the BDG a standard choice for steam turbine control solutions.
