Energy saving drives: savings are not only from motor speed control It is generally accepted that installing AC variable speed drives in fan, pump and compressor installations offers significant energy saving, reducing cost and lowering CO2 emissions. However, all variable speed drives are not equal: some VSDs include advanced software that provides further savings, […]
ABB’s new ACS480 general purpose and pump drive. At the 2016 SPS Fair in Germany, ABB launched their new ACS480 general purpose all-compatible drive to meet the energy-efficiency needs of a variety of light industries, including food & beverage, logistics & warehousing, and water & wastewater. Complementing the existing all-compatible ACS580 drive […]
Combat rising HVAC energy costs Building owners and facility managers are continually look for ways to save energy and money. Recent government regulations and the rising popularity of the “green building” concept have led to highly energy-efficient new building, but what about older buildings, and will retrofit projects that achieve energy efficiency to […]
The advanced optimum excitation control (AOEC) in Mitsubishi Electric’s FR-F800 series inverter drives continuously adjusts the excitation current to an optimum level providing highest motor efficiency. The newly developed AOEC, provides a large starting torque while maintaining the motor efficiency throughout the speed range. This is done without the troublesome adjustment of acceleration/ […]
While an industrial enterprise may realise its pumping system could be more effective, what may not be obvious is that energy-efficient pumps can help reduce utility expenses. Here’s why. Electricity costs account for 40% of the total cost of ownership (TCO) of a pump. By following energy management best practices, a manufacturer can decrease […]
