Efficiency of Boilers, Steams, compressed air depends on the circulation system. If the total circulating systems can be measured.. we can easily get the point of loss and take action to prevent it. Like wise we can keep the motors, generators, pumps monitored centrally. If the machines already has built in software based on SNMP .. the centralization can be done easily. The old machines can also be partially monitored using external censors and make a centralized system to monitor control and optimized. A single engineer from the NOC can monitor all the running machine and instruct from there for maintenance.
