In addition to operating their oxidizer reliably and efficiently, the customer requested that the new control system maintain communications with the plant distributed control system (DCS), interface with a remote annunciator panel, and collect a variety of data to help improve overall plant efficiency. We custom-engineered a solution with this advanced functionality. We installed a new HMI with the ability to send email notifications on alarms and to send emails with system data at a time interval based on an event. We also added ethernet interface cards to their existing VFDs that allowed for the collection of data such as the amount of torque used by the motors, their speed, and the amount of current drawn.
