These panels are for a heating and cooling application in large oil tanks.
They are a set of two control panels with a PLC, HMI and Starters and two Junction Boxes. The control panels used a series of Starters with varying HP’s to be controlled by Siemens PLC’s and HMI’s. The PLC’s regulated I/P transducers to simultaneously control the oil temperature of several, independent large oil tanks. The HMI’s allow the operator to monitor and control the temperature of each tank.
