Production of a dust emitted to the atmosphere, which is a side effect of many industrial processes, is a serious hygiene problem. The use of devices that are generally called precipitators serves reducing highly polluted gas emission. Constantly festering permitted emissions caused an increasing demand for high-efficiency devices for exhaust gases treatment. Polish company ELENERGY has confronted the market needs offering electrostatic precipitators, which are appropriate for a wide range of volumetric flow rate.
