Wallstein Rothemühle has stood for technical progress in electrostatic precipitator technology for decades. With innovative solutions and continuous further development, we have redefined the performance of dry electrostatic precipitators and set standards in industrial dust separation. Our electrostatic precipitators achieve residual dust contents of less than 5 mg/Nm³ in large coal-fired power plants - a record value made possible by patented technologies and our decades of expertise.

By taking over the filter technologies of "Apparatebau Rothemühle" and "Hamon Research Cottrell", we have a unique database with design plans for more than 2,500 filters installed worldwide. This valuable pool has made a significant contribution to tightening environmental regulations worldwide and significantly reducing dust emissions into the atmosphere.

Our electrostatic precipitators are used in numerous industries: from power and heating plants with coal or biomass firing to waste and sewage sludge incineration plants, refineries, steelworks, cement works and glass and paper factories. They impress with excellent dust separation rates of up to 99.99 %, combined with low energy consumption, high reliability and exceptional durability.

Wallstein Rothemühle has developed numerous technological innovations that make our electrostatic precipitators cutting-edge technology. These include Wallstein PowerPlus™, a high-frequency, high-voltage technology that ensures maximum performance and reliability. Delta Wings®, patented discs that optimize gas flow and dust distribution, minimize pressure loss while improving efficiency. Bi-Action® technology enables existing electrostatic precipitators to be modernized and increases dust removal efficiency without the need for structural changes. The portfolio is complemented by Bi-Corona®, an optimized electrode geometry that not only improves fine dust separation, but also reduces energy consumption by up to 10 %.

Our electrostatic precipitators are suitable both for modern new systems and for retrofitting existing systems from other manufacturers. With turnkey solutions, modernization services and comprehensive expertise, we offer tailor-made systems that guarantee maximum efficiency and environmental friendliness.
