Rivean Capital s'associe à Deltrian pour accélérer la création d’un leader européen de la filtration d'air.

Deltrian, one of Europe’s leading specialists in air filtration solutions and related consumables, today announces that Rivean Capital has acquired a significant stake in the company to support the Group’s next phase of growth.

Founded by the first generation of the Alexius family in the 1960s, Deltrian has been transformed under the leadership of the second generation, led by Jürgen Alexius, over the past four decades into a leading European platform for air filtration and air purification solutions serving industrial, commercial and technical applications. Today, the Group operates across more than 20 markets, generates approximately €130 million in revenue, and serves thousands of customers through one of the most extensive and effective sales organizations in the European filtration industry.

This transaction marks the beginning of a strategic partnership between Rivean Capital, Jürgen Alexius, Deltrian’s management team and the Group’s employees, united by a shared ambition: to accelerate Deltrian’s development and continue building a leading European air filtration platform.

Driven by powerful structural trends—including increasing focus on indoor air quality, energy efficiency, sustainability, stricter regulatory requirements and the modernization of industrial infrastructure—the European filtration market offers highly attractive growth prospects.

Combining deep technical expertise, strong customer proximity, recurring revenues generated through consumables and services, operational excellence and a strong culture of innovation, Deltrian is uniquely positioned to capitalize on these opportunities.

The partnership with Rivean Capital will enable Deltrian to accelerate:

• Organic growth across its European markets;
• The development of innovative air filtration and air quality solutions;
• Its buy-and-build strategy in a highly fragmented European market;
• The expansion of its geographic footprint and the further strengthening of its industrial and commercial capabilities.

Jürgen Alexius, majority shareholder and representative of the second generation of the Alexius family at Deltrian, commented:

“For more than fifty years, Deltrian has been built around a simple conviction: helping our customers improve air quality, reduce their energy costs and lower their carbon footprint. Today, thanks to the exceptional quality of our people, our strong European presence and the trust of our customers, we are ideally positioned to enter a new chapter of growth. We have found in Rivean Capital a partner who shares our entrepreneurial mindset, our ambition and our determination to build a sustainable European leader.”

Nicolas Linkens and Peter Hujoel, Senior Partner and Partner at Rivean Capital, added:

“We have been particularly impressed by the quality of Deltrian’s management team, the depth of its customer relationships, its innovation capabilities and its outstanding growth trajectory. The Group enjoys a highly attractive position in a market supported by exceptionally favorable structural trends. We are excited to partner with Jürgen Alexius and the entire Deltrian team as they continue this remarkable entrepreneurial journey and execute an ambitious organic and acquisitive growth strategy.”

 Gabriel Englebert, Managing Director and Head of Belgium at Lincoln International, commented:

“Under the leadership of Jürgen Alexius and his management team, Deltrian has built an outstanding European platform combining sustained organic growth, commercial excellence and recognized technical expertise. We are delighted to have advised the shareholders in identifying a partner that shares this long-term vision and is well positioned to support the Group’s continued growth, both organically and through acquisitions.”

Deltrian’s management team is making a significant reinvestment alongside Rivean Capital and will continue to play a central role in the future development of the Group.
