Widest portfolio of adsorbent technologies for a broad spectrum of applications. BASF provides high-quality products, proven technologies, and reliable services for the sulfur recovery process. By developing customized solutions, BASF supports customers increase sulfur recovery, optimize performance, and maximize profitability. Catalytic converters for aircraft cabins and fuel inerting. Cathode materials, e-mobility, next-generation technology solutions. Air cleaners that help to improve indoor air quality. Solutions for the most challenging applications. BASF maintains significant diesel research and development facilities around the world. These facilities are being used to develop the technologies needed to meet the extremely low emission levels called for in new emissions regulations. As the global leader in mobile emissions catalysts, BASF has developed a number of specialized catalyst technologies. BASF offers a "full loop" of precious metals products & services. Catalysts for chemical, petrochemical, and refining industries. We offer precious metals supply and full-loop management services, including refining to recover precious metals from spent catalysts. The development of fuels and chemicals based on biological feedstocks is critical to a sustainable future and BASF is proud to provide the catalysts to support this industry. BASF has established itself as a front-runner in this field by becoming the global market leader for sodium methylate, the homogeneous catalyst used for biodiesel production. BASF catalyst technologies play a crucial role in the manufacture of a wide range of fine and specialty chemical products including flavor and fragrances, herbicides and pesticides, resins, pigments and dyestuffs, pharmaceuticals, and plastic and rubber additives. BASF offers a broad variety of competencies, technologies and products to the fuel cell industry. With our long term experience in the fuel processing area we deliver adsorbents and catalysts needed to generate hydrogen for fuel cell applications with high efficiency. Chemistry plays an important role in the transformation of vegetable oils to products for our daily life. Catalysts are an indispensable tool to make this transformation possible. BASF offers more than 125 years of experience with oxidation catalysts. Each percent of catalyst selectivity advantage creates additional value and reduces COx emission. Solutions for power plants, process industries and more. BASF Catalysts has long been a leader in the development of highly active, robust and selective catalysts and related technologies for the destruction of volatile organic compounds (VOC). Thermocouples, pyrometers - insights for higher yields. Our contact temperature probes include profile and spike thermocouples, industrial thermocouples, fiberglass thermocouples, furnace thermocouples, and high-temperature thermocouple wire and cable. We also produce epitaxial thermocouples. Glass Industry Thermocouples have been a specialty of BASF for over 100 years. We have grown with the industry and, as glass technology requirements have expanded and changed over the years. Offering excellent accuracy, resolution, repeatability, and stability, EXACTUS® optical pyrometer technology provides significant performance advantages in non-contact temperature measurement in a practical, rugged and user-friendly design.

BASF updates the Abbreviated Component Maintenance Manuals for its Deoxo™ ozone and ozone/VOC converter portfolios

  • BASF Deoxo™ ozone and ozone/VOC converters catalytically remove ozone and certain odorous volatile organic compounds (VOCs) to deliver quality cabin air compliant with government regulations
  • The updated BASF Abbreviated Component Maintenance Manuals (ACMMs) redefine the test procedures and service methods for maintaining the converters
  • The converters are rotable parts and must be properly tested and maintained to ensure reliable performance

BASF announced today that it has updated its Abbreviated Component Maintenance Manuals (ACMMs) for the Deoxo™ ozone converters and ozone/VOC converters portfolio, with the release of revised ACMMs for the Airbus A320 airplane platform and the Airbus A330/A340 airplane platform. The updated ACMMs redefine the test procedures and service methods for maintaining the converters, to ensure continued industry-leading performance of its ozone converters. Proper testing includes functional checks of both ozone conversion efficiency and pressure drop for air transiting through the converter. BASF encourages airline operators to check with their current MRO (Maintenance Repair and Overhaul) service provider to ensure compliance with the updated ACMMs.

During flight, airplanes at high altitudes are exposed to significant levels of ambient ozone. If unabated, the ambient ozone enters the aircraft cabin through the air conditioning ducts. Prolonged exposure to ozone at concentrations typical of these altitudes is known to cause adverse health effects including headaches, fatigue, shortness of breath, chest pains, coughing, and irritation of the eyes, nose or throat.

During ground and taxiing operations, odorous VOCs can enter the aircraft cabin through the bleed air system. These VOCs may include exhaust fumes from jet engines on neighboring airplanes, exhaust fumes from airplane service vehicles and de-icing fluids. Engine oil and hydraulic fluids may also leak into the bleed air system. These odorous VOCs may result in crew and passenger discomfort or even alarm, precipitating aircraft diversions and delays.

BASF’s Deoxo™ ozone/VOC dual function converters catalytically remove ozone and certain odorous VOCs to deliver better quality cabin air. They are available for factory installation on new airplanes or as a field retrofit for airplanes already in service that either don’t have an ozone converter or would benefit from the performance upgrade from an existing Deoxo™ ozone converter.

BASF is the leading supplier of proven ozone and ozone/VOC catalytic converter technologies addressing the needs of aircraft OEMs to achieve compliant and comfortable cabin air quality for crew and passengers. We pioneered the first ozone converter over 30 years ago, and our ozone/VOC dual-function converter has been used on aircraft for over 15 years.

At BASF we create chemistry for a sustainable future and develop innovative solutions that ensure the long-term success of our customers.
