Reduce your energy costs in utilities

Compressed air systems

23

Up to 10% of electricity consumption in industry – equivalent to the output from 75 large nuclear power stations – is used to generate compressed air using compressors. Up to 95% is lost as unproductive waste heat in the process. And up to 30% of the compressed air generated “disappears” due to leakages in the supply network. Experience has shown that by implementing appropriate measures, this proportion can be reduced by up to 10%, thus reducing power consumption. In large-scale systems this can quickly equate to ten thousands or up to hundred thou sands of euros per year. Financial losses due to inefficient compressed air systems never theless continue to be underestimated, ignored or simply accept ed as a given. It doesn’t have to be like that! With Endress+ Hauser’s energy management solutions, you can reliably iden tify weaknesses and savings potential in your compressed air system, and permanently monitor the specific energy consump tion of compressors (kWh/Nm 3 ), for example. Compressed air systems Active reduction of energy loss and leakage

Savings made easy Waste heat, pressure losses, excess system pressure – all this also contributes to compressors being regarded as power guzzlers. Reduce your energy consumption by:

•  Taking in air for compressors at the coldest point (improved performance) •  Utilizing waste compressor heat (process air) •  Keeping system pressure low •  Shutting down compressors during unproductive times •  Checking the efficiency of a compressor (corrected volume flow vs. power consumption)

•  Minimizing leaks (less pressure loss) •  Monitoring filters (less pressure loss)
