Armstrong Fluid Technology has launched pre-programmed plant automation system controls for air cooled and water cooled variable primary chiller plants. The Armstrong IPC 9511 and IPC 9521 plant automation controls sequence the air cooled and water cooled chillers respectively, optimize pump operation, provide energy savings, and prolong equipment life while maintaining occupant comfort and process control. The plant automation control solution can be integrated with the reporting and remote read-write capabilities of any building management system. It includes the latest Armstrong technologies such as Multi Parallel pumping with sensorless technology. Since the sensorless technology is installed on the panel (not on the pump), any system – even systems including sensors – can profit from this control method.
