POELLATH powers a clean break for Dürr’s green division

Published at 03 Jul 2025

The sale represents another move in Dürr’s strategy to concentrate on automated production solutions.

German law firm POELLATH has advised the management of global mechanical and plant engineering company Dürr Systems on the sale of its environmental technology business to an affiliate of private equity firm Stellex Capital Management.

The Munich team that advised on the transaction included management investments and M&A/private equity partner Dr Benedikt Hohaus and associate Ida Süß.

The environmental technology business consists of the clean technology systems division within Dürr, which includes the areas of exhaust air purification technology and sound insulation systems.

The sale is part of Dürr’s wider strategy to create a leaner setup with three divisions instead of five; however, Dürr will retain a 25% stake in the environmental technology business.

The environmental technology business has an enterprise value of approximately EUR 385 million. After accounting for reinvestment and other transaction-related expenses, the Dürr Group anticipates net proceeds of around EUR 250 million from the sale. These funds will be used to strengthen the Group by reducing its debt. The transaction remains subject to customary approvals and is expected to be completed in the fourth quarter of 2025.

CEO of Dürr AG Dr Jochen Weyrauch said: “The environmental technology business has grown strongly in recent years and has established itself as the global market leader. However, it lies outside our strategic core business relating to automation technology. The new owner, Stellex, therefore offers better opportunities for further growth for environmental technology. Through this sale, the Dürr Group will become leaner and sharpen its strategic focus. We will use the proceeds from the sale to strengthen our company.”

Stellex partner Karthik Achar added: “We look forward to becoming the next steward of Dürr’s Clean Technology Systems Environmental division and we welcome the company into our investment portfolio. We view the division as a global leader in environmental filtration and pollution control solutions - critical technologies that serve a wide range of industrial and adjacent markets. Its long-standing customer relationships are a testament to the company’s engineering excellence. We are eager to partner with the management team and its employees in an effort to shape the next phase of its growth.”

Head of the clean technology systems environmental division Dr Sebastian Baumann commented: “We can look back on a successful development in the environmental technology business and are convinced that we can develop our potential even better as an independent company. With Stellex at our side, new opportunities for growth and innovation are opening up, both in our established business areas and in pioneering technology areas such as carbon capture and heat storage.”
