We put all our energy into saving yours
Electric motors account for more than two thirds of electrical energy consumption in industry within the EU. Introducing speed control can in some cases save well above 50 per cent. Emotron provides the technical solution, but also actively promotes energy efficiency on a wider scale. We strongly believe energy crises are not simply caused by a shortage of energy, but often by a surplus of inefficiency!
Existing technology to meet a global challenge
The world faces a great challenge: meeting the growing demand for energy while also improving the climate situation. Research is being conducted to identify renewable energy sources; something which is not mentioned quite as much is the option of saving energy by increasing efficiency in existing processes. This can be done today using proven and verified technology which offers immediate positive effects.
69 per cent of energy to electric motors
In industry within the EU, 69 per cent of electrical energy consumption is used to drive electric motors. The applications representing by far the greatest part of this consumption are pumps, fans and compressors. They also offer the greatest savings when speed control to continuously adapt operation to demand is introduced. The efficiency potential is estimated to be 20 to 50 per cent. For pumps the typical payback time for variable speed drives is one to two years.
Great energy savings with speed control
An EU survey shows that all electric motors installed in Europe consume a total of 800 TWh. 50 per cent of these operations are not suitable for speed control and a further 15 per cent are already controlled efficiently. For the remaining operations, the consumption can be reduced by 40 per cent, equivalent to 110 TWh. This corresponds to the total annual electricity consumption of the Netherlands with its 16.5 million inhabitants.
Promoting energy efficiency in Europe
Emotron is involved in the issue of energy savings as an endorser of the EU’s Motor Challenge Programme (MCP) and as a member of the organization of Swedish Energy Efficient Companies. MCP supplies tools to European companies which undertake to reduce energy consumption by improving the efficiency of their electric motors. Emotron contributes by spreading the knowledge about speed control and by supplying the technical solution.
Emotron customer saves EUR 25,000 per year
One example which clearly illustrates the great energy-saving potential of electric motor driven systems is the industrial processing company INEOS. Controlling one single fan using an Emotron variable speed drive reduced energy consumption by 25%, saving the company EUR 25,000 per year.
