Wallstein Rothemuhle

What Wallstein Rothemuhle does

Wallstein Rothemuhle Sp. z o.o. is a Polish industrial engineering firm specializing in environmental protection equipment for heavy industry. Founded in 2004 as Balcke-Durr Polska, the company was acquired in 2020 by the German family-owned Wallstein Holding GmbH & Co. KG, simultaneously acquiring the Rothemuhle technology portfolio, and was rebranded to its current name. Headquartered in Warsaw with a branch in Tychy, the firm employs approximately 50 specialized engineers and holds ISO 9001, 14001, 45001, 1090, and 3834 certifications (renewed through 2028).

The company's product portfolio centers on air pollution control and heat exchange equipment: electrostatic precipitators (ESPs), fabric filters, and rotary air preheaters (LUVO and GAVO types). The underlying technology is anchored in Rothemuhle's proprietary designs, supplemented by a 2019 licensing agreement with Howden Rothemuhle GmbH that grants access to a global reference base of over 1,200 installations, bringing the firm's combined historical reference count to more than 2,500. The firm also offers modernization services for existing installations, spare parts, and an electrical services line (E-Serwis). A notable technical milestone was the third ESP delivered to Elektrownia Opole, which achieved a record-low 3.5 mg/Nm3 dust emission concentration, establishing a domestic benchmark for BAT-compliant ESP performance.

Revenue is generated through capital equipment projects (turnkey design, manufacturing, installation) and aftermarket services (modernization, spare parts, electrical services). The customer base is concentrated in power generation but extends across chemical, steel, cement, paper, glass, and waste-to-energy sectors, with named clients including PGE, Elektrownia Opole, ArcelorMittal, Veolia, EDF, ENGIE, and Solvay. The business model relies on long procurement cycles typical of capital equipment sales, with after-sales service and modernization contracts providing a recurring revenue layer on top of the lumpy new-build pipeline. Growth has been recognized externally through three consecutive Gazele Biznesu awards (2020–2022) and three Forbes Diamonds recognitions (2023, 2025, 2026).
