High Voltage



Power Supply for Electrostatic Precipitator Environmental protection concerns take centre stage today when it comes to fossil-fired power stations and particulate polluting industries. Improved efficiency and enhanced pollution control not only helps to get closer to the objective of a clean environment but also helps industries save valuable raw material going waste. Hirect Power Supplies for electrostatic precipitators with their particularly high efficiency and control leads the way towards clean Environment.
