An electrostatic particulate filter is a highly efficient separation system designed to reduce fine dust emissions from wood-fired heating systems and biomass plants. The dust particles contained in the flue gas are electrically charged and collected on dedicated separation surfaces. In Switzerland, electrostatic particulate filters are used to reliably comply with the emission limits defined by the Air Pollution Control Ordinance (LRV).
An electrostatic particulate filter consists of a high-voltage unit, a discharge electrode for generating the electric field, and integrated collection surfaces within the flue gas path. The electric field electrostatically charges the fine dust particles, causing them to adhere to the grounded collection surfaces. The collected particles are removed automatically at regular intervals through a defined cleaning cycle, ensuring consistently high filtration efficiency and reliable compliance with emission limit values.
Depending on system design and operating conditions, an electrostatic particulate filter achieves a separation efficiency of 90–95%. Actual emission reduction depends on factors such as fuel quality, system output, flue gas temperature, and maintenance intervals. Meisterfilter designs each filtration system individually to ensure reliable compliance with applicable emission standards.
Electrostatic particulate filters are characterized by high separation efficiency combined with minimal pressure drop. Compared to mechanical filtration systems, energy consumption remains low and the overall efficiency of the heating system is hardly affected. Meisterfilter systems are low-maintenance, durable, and individually adaptable — including for high-capacity industrial applications.
Electrostatic particulate filters from Meisterfilter are suitable for pellet heating systems, wood chip boilers, large-scale industrial baking ovens, as well as commercial and industrial biomass plants. The systems can be integrated into new installations or retrofitted to existing wood-fired heating systems, covering a wide performance range — from smaller boilers with outputs starting at 100 kW to industrial-scale plants in the multi-megawatt range.
Yes, Meisterfilter’s electrostatic particulate filters are also suitable for larger commercial and industrial biomass plants exceeding 500 kW. Each system is individually engineered based on flue gas volume, output class, and the required level of emission reduction. Meisterfilter delivers solutions ranging from smaller heating systems to large-scale industrial installations with outputs of several megawatts.
The planning of an electrostatic particulate filter begins with a detailed analysis of the existing heating or biomass system. Key factors include system output, flue gas volume, fuel type, and the applicable emission limit values. Meisterfilter carries out a project-specific system design and precisely sizes the filter solution to match the respective installation — from smaller heating boilers to industrial plants with outputs of several megawatts. Following the technical coordination phase, the system is delivered, installed, and commissioned.
In Switzerland, emission limits are regulated by the Air Pollution Control Ordinance (LRV). Depending on system size, output, and location, the installation of an electrostatic particulate filter may be required. Meisterfilter supports plant operators in meeting legal requirements and provides project-specific consultation to ensure full regulatory compliance.
Emission limit values for wood-fired heating systems and biomass plants are regulated in the Swiss Ordinance on Air Pollution Control (OAPC). They vary depending on the plant’s capacity class and system type. For installations up to 500 kW nominal heat input, particulate matter limits of 50 mg/m³ typically apply, while for systems above 500 kW, limits of 20 mg/m³ are commonly required. The specific requirements and enforcement practices may vary depending on the competent authority and location. Meisterfilter takes all current regulatory requirements into account for every system design, ensuring a technically sound and compliant implementation.
Yes, Meisterfilter electrostatic particulate filters are suitable for retrofitting existing wood-fired heating systems and biomass plants. Adequate space within the flue gas path and a technical system assessment are required to ensure proper integration.
An electrostatic particulate filter requires regular cleaning of the collection surfaces and inspection of the high-voltage unit. Meisterfilter provides maintenance and service solutions to ensure consistently high separation efficiency and operational reliability.
Operating costs primarily consist of the power consumption of the high-voltage unit and routine maintenance. Energy demand remains low relative to the overall heating capacity and depends on system size and operating hours.
With proper installation and regular maintenance, an electrostatic particulate filter can operate reliably for many years. Meisterfilter systems are designed for durability, and wear components are inspected and replaced as needed during maintenance.
Modern Meisterfilter electrostatic particulate filters are designed to maintain minimal pressure drop within the flue gas path. When properly dimensioned, the efficiency of the wood-fired heating system or biomass plant is only marginally affected.
Funding programs for electrostatic particulate filters may be available at cantonal or municipal level. Meisterfilter advises customers on potential funding opportunities and supports the technical evaluation of each project.
Meisterfilter operates throughout Switzerland as well as across the DACH region. In addition to projects in Germany and Austria, the company also delivers electrostatic particulate filters in Italy. Through project-specific engineering and customized system design, national emission regulations are carefully considered. Meisterfilter supports customers from initial technical design through delivery and installation to final commissioning — for both new systems and retrofits.
Meisterfilter develops, supplies, and installs electrostatic particulate filters for wood-fired heating systems and biomass plants in Switzerland. Each project is engineered in accordance with applicable emission limits, system capacity, and specific customer requirements — from planning to commissioning.
