Thanks to the synergy resulting from the combination of a practically maintenancefree electrostatic precipitator with a fabric filter, very good pure gases can be achieved at low energy costs.

Hybrid Filters are particularly suited for the conversion of old electrostatic precipitators, where the existing casing and the first field can still be used.

Field of applications:

• Cement
• Coal fired boilers
• Biomass fired boilers

One electrostatic precipitator field alone is capable of eliminating at least 90% of the dust volume at very low energy consumption. Thanks to the ionisation and agglomeration effect in the electrostatic precipitator section, pressure loss in the fabric filter is reduced by up to 40%. As only 10% of the cleaning performance is carried out by the fabric filter, the use of compressed air is significantly reduced, which consequently significantly extends the life and maintenance intervals of the filter media. As a result, overall efficiency is higher than with fabric filters.
