The energy efficiency of the plant engineering system is the ability of the system to deliver the same service with less energy consumption. This capability is achieved by controlling everything in the best possible manner to reduce energy losses while achieving the same final comfort. Also important is the correct and continuous maintenance of the 'health condition' of the entire plant over time. For these purposes, this division includes all products for controlling and regulating process variables such as flow, temperature, humidity and pressure, as well as products required for maintaining plant health.
