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 […]
How many times have you heard someone say about a machine “If it ain’t broke don’t fix it”? Probably too many times, when the truth is often the reverse. Plastic container maker PrimePac in Northern Ireland discovered this recently when replacing a failing drive and motor package gave then a 60% percent fall […]
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 […]
Electric motors are part of our way of life: in the home, in industry and in commercial buildings. According to Schneider Electric, motors consume 30% of the energy of a building, and 60% of the energy of industries and infrastructures. In business, 85% of electric motors control pumps, fans and compressors and by reducing motor […]
