A dust collecting plate which is a also known as an ESP plate that absloutely a critical part of an electrostatic precipitator system. It serves as the collecting electrode that attracts and captures charged dust particles and pollutants from industrial exhaust gases. These plates are placed parallel within the ESP system which is forming the positive electrode counterpart to the negative cathode wires.
SENOTAY dust collecting plates—also known as collecting electrodes—are engineered to provide the grounded surface for ionized particulate inside Electrostatic Precipitators (ESPs). Featuring a specialized roll-formed profile with integrated aerodynamic pockets, these heavy-duty metal plates shield captured dust from high-velocity flue gas streams, preventing re-entrainment during rapping cycles. They deliver consistent electrical grounding and structural rigidity across demanding thermal power, cement manufacturing, and heavy steel milling plants.
