HEC Cleaning

Irregularities in system operation often lead to an increased differential pressure in the filter system

This increases the power consumption of the ID fan and can lead to a failure of the entire process.

The Kayser HEC process provides a quick remedy here, in which the built-in filter bags are cleaned individually with the HEC cleaning device. The specially modulated compressed air pulse results in a significantly higher pressure and a larger quantity of primary compressed air than with the system's own pulse jet cleaning. The forces that occur also blast off larger agglomerations.

  • Supporting cages and filter hoses remain installed
  • Fast throughput time, also possible during plant operation
  • Sustainable cleaning success
  • Lower compressed air consumption compared to other in-situ cleaning processes, making it sustainable and cost-effective
  • Possible with vertically and horizontally installed filter bags
