As of 16 June 2011, only highly efficient 2- to 6-pole rotary current asynchronous motors must be introduced into the European market according to an EU directive. They must achieve at least efficiency class IE2 (IE = International Efficiency), corresponding to the previously highest European efficiency class EFF1. Siemens offers energy-efficient drive alternatives for all affected motor series to make transfer easy – which is highly necessary. The next increase of requirements has already been announced for 2015.
Identify, evaluate, implement. Again and again.
More than ever, economic production today means that companies need to systematically analyze their complete system and production processes, consistently and repeatedly. With the matching hardware and software, you will be able to record, visualize and analyze energy flows to better identify energy guzzlers.
Then, possible measures for energy optimization must be evaluated under consideration of their efficiency and savings potential. Concrete measures can thus be taken to make best use of energy savings potentials in production. Special focus should be on drive technology, which makes up about two thirds of the industrial energy demand. With energy management according to EN 16001, productions can now comply with the high market requirements, such as the EUP directive (directive on environmentally compatible design of products) or rising energy demand.
Competition is subject to the same legal requirements and economic forces and needs to act. Every company, no matter the size and industry, is bound by standards. Every new standard will again be replaced by the next. Again and again. System operators, planners and machine engineers need to continually optimize energy consumption, materials and resources.
Success factor energy efficiency
Creating transparence regarding the demands of, e.g., power, gas, vapor, compressed air, heat and cold or switching to energy-efficient motors are important initial steps. Systems must become more productive, efficient and flexible regarding technology, control and smart networking. This investment will pay off. Modernizations can save up to three quarters of the previous energy costs. This constitutes essential leverage for higher efficiency and growth, in particular in the light of rising energy prices. Energy efficiency is more profitable than ever. With answers from Siemens.
