Haniel portfolio company CWS Cleanrooms acquires majority in STAXS®, a leading Cleanroom Consumables partner to the life sciences industry

Duisburg, 9 May 2022. Franz Haniel & Cie. GmbH (“Haniel”) has agreed with Pan-European private equity firm Silverfleet Capital and management on the acquisition of a majority stake in STAXS® Contamination Control Experts (“STAXS” or “the Company”). With this acquisition, Haniel’s portfolio company CWS Cleanrooms further strengthens its position as the first full-service provider for cleanrooms in Europe.

STAXS is the leading value-added distributor of cleanroom consumables for Life Sciences and other industries in the broader Benelux region. As the contamination control expert, it has built an excellent reputation for quality and reliability. The acquisition of STAXS underpins the ambition of Haniel and CWS in building a strong independent cleanroom business, allowing for further growth across European markets. Under the CWS Cleanrooms umbrella, STAXS will represent the Cleanroom Consumables platform and continue to service its customers as a separate company. The management team around Johan-Detlef Dubbelboer, Stijn Van Eenoo, Wico Maltha, Jeroen Juffermans and Katia Poppe will remain committed as shareholders of STAXS.

As a company of the CWS Group, CWS Cleanrooms is part of Haniel’s “Planet” investment pillar. To implement its “enkelfähig” purpose, Haniel is currently focusing on expanding the “Planet” portfolio. 

“STAXS has a strong value proposition and an impressive growth track record. The business operates in a highly attractive niche market with structural underlying growth. I am looking forward to partnering with STAXS and management in continuing the journey together with CWS Cleanrooms,” said Moritz Merkert, Senior Investment Manager for Haniel’s Planet pillar. 

“With this acquisition, we are further expanding our international portfolio of services for our customers in the highly specialized cleanroom segment. At CWS Cleanrooms, we are Europe's first provider to offer textile services, cleaning, training, on-site services and consumables from a single source. Together with the existing management team, we will continue to expand the positioning of CWS Cleanrooms in Europe”, said Markus Schad, Managing Director CWS Cleanrooms.

Johan-Detlef Dubbelboer, CEO of STAXS stated: “It has been a pleasure to work with the Silverfleet team over the past three years and to develop the business over that time into the strong shape we are now in. We look forward to a bright future within the Haniel Group as we embark on our next stage of development.”

STAXS has seen a strong growth trajectory in recent years. Its product portfolio consists of its own brand DOTCH® as well as leading third-party brands, comprising top-quality disinfectants and detergents, wipes, mops, gloves and disposable garments ensuring safe cleanroom operations. STAXS is a leading player in the Benelux contamination control market with a strong customer base in the Netherlands, Belgium and Germany. The company was founded in 1995 and operates out of Heerenveen, The Netherlands, as well as Niel, Belgium. Completion of the acquisition is scheduled for later in May 2022 and is not subject to further closing conditions.
