Dry Electrostatic Precipitators
The R&R-BETH® Dry Electrostatic Precipitators are designed to significantly reduce dust emissions, bringing them well below the legal limits of 20 mg/m³ (0.00873 grain/ft³) under standard conditions. Our units can even achieve values below 5 mg/m3 (0.00219 grain/ft3). These systems offer numerous benefits over traditional media filtration systems, including:
- Low Energy Consumption:
They require less energy to operate, making them more cost-effective and environmentally friendly. - High Operational Reliability:
These precipitators are designed for consistent and dependable performance, reducing the likelihood of operational disruptions. - Low Maintenance Requirements:
Their design minimizes the need for frequent maintenance, which can save both time and money. - Cost Efficiency:
They have lower initial investment costs, making them an economically viable option for industries looking to reduce emissions.
These key features make R&R-BETH® Dry Electrostatic Precipitators an efficient and cost-effective solution for controlling dust emissions in various industrial applications.

How the Electrostatic Precipitator works

The dust-laden process gas enters the electrostatic precipitator horizontally, where it is evenly distributed to create a consistent flow across the entire filter profile. High-voltage discharge electrodes generate an electric field that charges the dust particles as they pass through. These charged particles are attracted to the collecting electrodes, where they combine with already separated dust. The accumulated dust is dislodged by drop hammers and falls into the filter hopper for removal via the material discharge system. The purified gas is released out of the clean gas hood.
