Calistair's catalytic air purification modules for wheat flour facilities
Calistair offers advanced catalytic modules that integrate with existing HVAC systems to eliminate airborne contaminants in wheat flour facilities, achieving over 96% efficiency in removing bacteria and fungi with minimal pressure drop.
Overview
Calistair's innovative solution provides a cutting-edge method to significantly reduce airborne contaminants in wheat flour facilities. By utilizing catalytic modules that seamlessly integrate with existing air handling units and HVAC systems, this technology effectively eliminates pathogens—including Gram-positive and Gram-negative bacteria, fungi, and volatile organic compounds (VOCs)—in a single air exchange. Unlike traditional HEPA filters, Calistair's system offers minimal pressure drop and avoids clogging, ensuring efficient operation in high airflow environments.
Technical specifications
Calistair's patented technology combines catalysts such as titanium dioxide (TiO2) and manganese oxide (MnO) with adsorbents like zeolite, all coated on aluminum honeycombs. Activated by UV light, this combination effectively destroys the cell walls and RNA/DNA of microorganisms. Key performance metrics include:
- Gram-Positive Bacteria: Over 96% removal efficiency for pathogens like Staphylococcus aureus and Bacillus cereus.
- Gram-Negative Bacteria: More than 99% purification efficiency for Escherichia coli.
- Fungi: Over 93% removal efficiency for Aspergillus.
This technology is already validated and tested in diverse environments such as hospitals, laboratories, and poultry hatcheries.
Technology readiness level
With a Technology Readiness Level of 9, Calistair's modules are fully developed and validated, ready for immediate deployment in industrial settings. The technology has been proven effective through independent third-party testing, and recommendations for clients include piloting in real-world locations and further independent testing to verify effectiveness under specific conditions.
About Calistair
Founded in 2014, Calistair is a material science and chemical technology company specializing in innovative air purification and contaminant capture. Its core technology, the Calistair Technology, utilizes a proprietary non-thermal catalysis method integrated into modular reactors. These reactors combine honeycomb structures impregnated with advanced materials—such as zeolites and metal-organic frameworks (MOFs)—with UV-C activation. This process generates hydroxyl and superoxide radicals that effectively mineralize and destroy airborne biocontaminants, volatile organic compounds (VOCs), chemical pollutants, and viruses, including coronaviruses, without producing toxic by-products like ozone. The technology is designed for scalability and high-velocity airflow, allowing it to be retrofitted into ventilation systems or utilized in dedicated air purification units.
Calistair's solutions are engineered to improve safety standards in environments ranging from hospitals, laboratories, and cleanrooms to industrial buildings and public spaces. The company serves a global client base, including medical facilities requiring high particulate cleanliness standards and industrial sectors focused on emission reduction and gas purification. Since its inception, the company has received recognition for its contributions to public safety, notably during the COVID-19 pandemic, and continues to advance its material science research for applications in energy storage, defense, and pharmaceutical sectors. Headquartered in France, Calistair maintains integrated R&D and manufacturing capabilities to support the implementation of its air decontamination technology across diverse industrial and medical applications.
