What clean tek does

clean-tek Reinraumtechnik GmbH is a German manufacturer of modular cleanroom systems, headquartered in Renningen and operating as a wholly-owned subsidiary of Swiss-domiciled clean-tek Holding AG (Basel). The company designs, produces, and supplies a vertically-integrated cleanroom component portfolio, including proprietary ceiling systems (ceil-tek Bandrasterdecke, T-Grid Kreuzbandrasterdecke, clean-ceil Klemmkassettendecke), wall systems (GMP 50 / GMP 100 Wandsystem, Vollglaswand, Bi-Wall), cleanroom doors, and a full component range covering HEPA Filter-Fan-Units, laminar-flow modules, cleanroom luminaires, weighing booths, material hatches, and decontamination showers. These products are engineered to work together as integrated, customizable cleanroom systems rather than as standalone hardware items, and are qualified for GMP-regulated pharmaceutical and medical-device environments (ISO 9001:2015 certified, Certificate QAS9001-GM2229-24-27).

The company's commercial model is project-based and quote-driven, with no public pricing. Sales are executed through a direct, territorial sales force covering the DACH region — led by a Sales Director DACH and a Sales Management & Business Development function, supported by North and South area sales managers — plus a corporate website serving as the top-of-funnel information channel. Customer focus is primarily pharmaceutical and biotech, with secondary verticals in medical/healthcare and electronics/semiconductor manufacturing; pain points addressed are contamination control, GMP compliance, and regulatory qualification of controlled environments. Geographic footprint is anchored in Renningen, with a project office in Bensheim and a Swiss operating subsidiary (Clean-tek Reinraum- und Hospitaltechnik AG) extending coverage into Switzerland.

Operationally, clean-tek serves as the German execution entity of a broader Swiss-led group, with the holding company in Basel acting as sole shareholder. Distribution is direct, not channel-based, and the company does not disclose revenue, headcount, or backlog in the available source material. The company's stated emphasis is on sustainability and design-oriented cleanroom technology, and it positions single-manufacturer turnkey delivery as its core differentiator versus multi-vendor cleanroom assembly.

Emerging players

• AES Clean Technology: US-based provider of modular cleanroom solutions and containment technologies for pharma, biotech, and life sciences. Compares to clean-tek on modular cleanroom design and GMP-compliant construction, focused on the North American market.
• Drexel + Weiss: Austrian manufacturer of cleanroom components including air handling units, FFUs, and cleanroom ceilings. Overlaps with clean-tek's filter-fan-unit and laminar-flow product lines, particularly in the DACH region.
• Terra Universal: Manufacturer and supplier of cleanroom equipment including modular wall systems, ceilings, FFUs, and contamination-control accessories. Overlaps with clean-tek's product portfolio, particularly for smaller-scale and laboratory cleanroom applications.

Broad incumbents

• Exyte (formerly M+W Group): Global engineering, construction, and project delivery specialist for high-tech facilities including semiconductors, pharma, and biotech cleanrooms. competes with clean-tek on turnkey pharma cleanroom projects but at significantly larger scale and global footprint.
• Weiss Klimatechnik (Schunk Group): German manufacturer of climate-controlled environments, cleanrooms, and environmental simulation chambers. Competes with clean-tek in pharma/electronics cleanroom construction but operates as part of the broader Schunk industrial conglomerate with deeper resources.

Regional players

• G-CON Manufacturing: US-based manufacturer of prefabricated, modular cleanroom 'PODs' for pharma and biotech. Comparable to clean-tek's modular turnkey approach but primarily serves North American customers, making it a regional rather than direct competitor.
• ClorDis (Christeyns group): European specialist in cleanroom and controlled-environment cleaning, disinfection, and contamination control services. Adjacent to clean-tek's customer base in DACH pharma/medical, but provides services rather than physical cleanroom systems.

Direct peers

• Lindner Group: Bavaria-based international contractor offering cleanroom fit-out, wall/ceiling systems, and interior finishing for pharmaceutical and industrial clients. Directly competes with clean-tek on DACH cleanroom projects and is significantly larger.
