Inspections of ABB in more than 2.000 industry move systems have shown possibility of energy savings by average 31% by motor.
The ABB, from June util September of 2023, study more than 2.000 industry electric engines at the field of Electric Inspection and it has tracked a prospect of saving energy of up to 31%, by average, which means more than 2,1 TWh of the 20 year life cycle of those systems. The Energy Inspections help the industry to track down the spots with the biggest possible energy saving at the moving systems, so that they can consider the best decisions about the investments on the section of energy saving and the depreciation of the corresponding investments (ROI). The Inspections collect functioning data from machine moving systems from the field. One expertized mechanic makes the comparisons of those values, with the theoretical performances where they could be achieved with the addition of one requlator of cycling variabled speed tester (VSD), the right distance inspection or the modernization of the equipment.
The improvement of the energy efficiency give the possibility at business to reduce the consumption of electric energy, with surprizing reduction of the CO2 emissions and a short depreciation for the investment (ROI), which depends from the energy mixture of every country. For example, if all the engines whic were inspected were functioning in a country like the United Arab Emirates, one energy saving of 2,1 TWh would be equal to 1,5 million tons of CO2 emissions and depreciation in a time of six months. In Germany it would be equal to a saving of 940.000 tons of CO2 and depreciation of the investment in three months**. This saving would be enough to offset the carbon emissions of one factory for 2 months in Germany and for 3 months in the United Arab Emirates.
«At the time where the world, in the context of COP28, will be searching for the confrontation of climate change, the facts are showing that it is possible to do the right thing for the planet, as much as for the corporations. The realization that it can be achieved an energy saving of class 31% in 2.000 engines it shows the fact that the systems of electric moving form on great unexploited chance for the improvement of a society with low carbon monoxide emissions», was stated by Erich Labuda, President of Technical Support Department of the Motion Systems Sector of ABB.
With more than 300 million biomechanic elctroengines on the world, the results are showing the great prospects of saving energy and CO2 emissions, especially when more than half the electroengines are over 20 years old and are lacking in modern technology of high performance.
The engines that were inspected server many industries, such as food and drinks, chemical process, energy and HVAC(heating, cooling and air conditioning). Covering one big magnitude of engine applications low and middle voltage, such as pumps, fans and other systems. The inspections have shown constant motives in performance between different applications where they are used in engines, with those that consern fans to provide usually the greatest energy saving. Furthermore research has tracked that the greatest chances are related with engines which function with cycle regulators, which control the speed or the torque of the engines to match exactly the production with demand, fact that reduces the consumption of energy.
These findings are enhancing the exposure of "The Case for Industrial Energy Efficiency" which was published recently from the Movement of Energy Efficiency. This exposure has as a purpose to provide in the industry basic information for 10 actions based in modern technologies, which contribute in the limitation of total cost and emissions and they can be applied directly without the need of complicated procedures.
