The MCC division delivers molecular filtration solutions in light processes, industrial applications, cleanrooms and buildings where indoor air quality matters the most, such as airports or offices.
With over 100 years of combined expertise—strengthened by the integration of BION—we deliver advanced solutions that remove harmful gases, vapors and odors from air.
We provide complete, end-to-end solutions by combining high-performance filtration media, engineered equipment, and dedicated services.
Our technology-driven approach is built on deep expertise in adsorption chemistry, system design, and real-time monitoring.

including Indoor Air Quality, Corrosion and Odor Control, Emission Control, Process Protection, Biogas Purification, and Postharvest Solutions.
With a global footprint and strong local presence, we partner with our customers to improve air quality, protect critical processes, and drive more sustainable and efficient operations.
The corrosion control product range is supported by a comprehensive range of filters, sales tools and site services. We are a leading manufacturer of UL-certified activated alumina adsorbents (CamPure™) as well as plastic modules (CamCarb™), housings for filters and adsorbents (PSSA, VDBs) or analytical services (corrosion coupons, ISA Check online monitors, media post-mortem tests).
For the last 20 years, we have revolutionised molecular contamination control in microelectronic facilities with the introduction of GigaPleat™, the cleanest product on the market designed for cleanroom applications where activated carbon particle emissions and outgassing cannot be tolerated. GigaPleat is available with a wide range of adsorbent media such as ion exchange resins or activated carbon, adapted to the different chemicals observed in microelectronic facilities including, acids, bases, condensables, oxidants, VOC, dopants and refractory compounds.
Heavy-duty products are most often applied to the exhaust field with a range of so-called deep bed products (ProCarb) for high loads and/or very high removal-efficiency requirements, as well as containment applications (ActiCarb). Finally, our versatile product line also includes combination filters for air handling units with limited space to control both particulate matter and gaseous chemicals within a single filter stage (CityCarb).
All these products are specially designed and tested with chemicals relevant to each application. Our unique ISO 10121 molecular test rigs for full filter sizes as well as our lifetime calculation and design software bear witness to our 55 years of experience in this field and help to ensure proper dimensioning and guaranteed results.
