ESP – Electrostatic Filters

Electrostatic precipitators (ESP) are crucial to an energy plant and regular cleaning is essential to maximise efficiency and reduce unscheduled shutdowns.

The most effective solution for this is online shockwave cleaning. Online Cleaning Technologies has several alternative online solutions to clean ESP’s while the installation is operational.

Traditional cleaning methods require plant shutdown after the ESP is blocked. This can be extremely costly.

It has been consistently demonstrated that facilities which utilise online shockwave cleaning of ESP’s, avoid the need for regular shutdowns.

Online shockwave cleaning is an efficient and innovative alternative to help clients save time and money.


  • The best solution to effectively and rapidly clean the ESP
  • Increased efficiency up to 110%
