Inverter drives (VSDs) with an integrated PLC enable system designers to design out a standalone PLC in a wide range of machine application. This simplifies panel design and wiring, reduces size, and saves cost. In addition to providing local control, the PLC function can also be used for condition monitoring and provide machine data […]
When modernising a city centre underground car park’s ventilation system, the owner wanted to improve air quality and improve efficiency to reduce energy costs. To achieve this, the new system needed to provide a dynamic response to actual vehicle movements. The fume extraction ventilation system consisted two centrifugal extraction fans located in a common […]
Booster control is used to maintain a constant pressure at the outlet by automatically varying the speed of the pumps. Altivar Process ATV600 drives allow the pumps to have an optimised consumption of power whilst time providing optimal monitoring features. Booster Control is used in several pumping processes. A typical application is water and […]
Companies buying new machines should think more about the energy that will be consumed by the machine during its lifespan says Schneider Electric. Among expenses from acquisition to dismantling, the purchase price accounts for only 2 to 3% of the overall costs: the remainder of the expense being mainly energy consumption. Machines are designed […]
ABB inverter drives with DTC improve cement kiln control and lower energy use. Portland cement clinker is made by heating a mixture of raw materials in a rotary kiln at high temperature, before being ground into a fine powder, for use as the binder in many cement products. ABB drives with DTC […]
