E3 Holding SE acquired 100% of Clean-tek Group on 20 October 2022. Clean-tek Group is a leading full-service clean room specialist; from planning and production right through to assembly – Clean-tek clients benefit from the company’s very own first-class production technology. 

Clean-tek is a leading manufacturer of modern and efficient clean room systems; whilst its core markets are Germany and Switzerland, the company, which is now under the investment umbrella of E3 Holding, also services international clients. Its principal sites are located in Renningen (Germany) and Basel (Switzerland). Clean-tek’s product offering includes wall, ceiling and door systems, as well as equipment such as laminar flow modules, pass-throughs, personnel and material locks, decontamination showers and weighing booths – all manufactured in-house. 

The modular design of Clean-tek’s clean rooms allows for optimal adaptation to any spatial requirement, along with simple, fast assembly, conversions and extensions. Every Clean-tek clean room complies with GMP, FDA and ISO requirements, and is suitable for all types of hygienic production.

Clean-tek has been an established supplier of comprehensive high-quality clean room system solutions for 30 years, with a strong focus on the pharmaceutical sector. The company was founded in Renningen in 1986 by Albrecht Ritter, father of the current Managing Director Felix Ritter, and employs around 65 staff members. For 2022, the company expects a turnover of approx. €22 million. 

Looking ahead, Clean-tek’s target market offers excellent opportunities to continue its growth trajectory. The market for clean room technology is driven by investments from the biotech, pharmaceutical and semiconductor industries, along with an ever-growing number of hygiene and manufacturing standards in other industries such as cosmetics and food. All these industries post average growth rates of 5-7% p.a. 

My goal was to team up with experts to guide the transformation of our family business into a mid-sized industrial firm. E3 Holding’s approach to business – making a company fit for the future, holding it for the long term, reading the signs of the time and integrating ESG factors – resonated with me. Plus, the relationship with Mr Weddrien and Mr Rieder is excellent.

Clean-tek is led by an experienced team, consisting of current Managing Directors Felix Ritter and Holger Lautenschlager. The transaction was financed with Nord/LB Hanover.

Clean-tek Group’s excellent positioning in a resilient and high-growth market, coupled with additional growth potential via further operational development, for example in the company’s ongoing digital transformation, convinced E3 Holding of this attractive investment.
