ESP

ESP - Electrostatic Precipitator is the most cost effective industrial particle emission control device. It functions by removing particles from gas stream using induced electrostatic charge, which has very minimum impeding of flow.

 

  • Electrode point charge particles negatively (e.g. dust or smoke)
  • Collector plate positively charged
  • Law of attraction – particles collected at plate

 

 

  • High Collection Efficiency >99%
  • Easy Operation & Maintenance - 1 operator with no moving parts
  • High Operating Temperature 200°C-850°C
  • Wide particles size range 0.01µm to 100µm
  • Wide Capacity Range - modular to meet any flow rate
  • Low Pressure Lost < 3 mbar
  • Life expectancy > 20 years
  • Robust & reliable construction
