About Danfoss IXA Sensor Technologies

Danfoss IXA Sensor Technologies, a subsidiary of the Danfoss Group, operates within the maritime industry, focusing on certified marine emission monitoring solutions. Established as a private stockholding company in April 2009, its origins trace back to an internal project within Danfoss Heating and later Danfoss Ventures, initially aimed at measuring air quality in office buildings. This endeavor evolved to address a gap in the maritime market for emission sensors specifically designed for sea vessels, as existing solutions were primarily land-based adaptations.

The company provides advanced sensors and systems engineered to help the shipping industry comply with environmental regulations and enhance energy optimization. Its clients include ship owner-operators, shipyards, system integrators, and OEMs. Danfoss IXA's business model centers on the development, sale, service, and commissioning of these specialized sensors and systems. The firm's products are built to be robust and withstand harsh maritime conditions.

A core product is the Marine Emission Sensor (MES) line. The MES 1001 measures harmful gases like NOx, SO2, and NH3 directly in the exhaust pipe, providing real-time data crucial for regulatory compliance and for optimizing the performance of after-treatment systems like Selective Catalytic Reduction (SCR). This sensor utilizes patented ultraviolet absorption spectroscopy and features a self-calibrating, in-situ design that simplifies installation and maintenance. Another key product, the MES 1003 Washwater Monitoring System, is used on vessels with scrubbers to measure pH, PAH, turbidity, and temperature in the washwater, ensuring compliance with International Maritime Organization (IMO) guidelines. The company also offers the MES 1002 for SO2/CO2 analysis and a MARPOL-approved NOx analyzer.

By providing precise and continuous data, these technologies enable shipowners to document their emissions, meet legal standards such as the MARPOL NOx technical code, and improve fuel efficiency. The data can be transmitted to a central server, allowing for long-term analysis and fleet-wide comparisons. This positions Danfoss IXA as a key technology provider supporting the maritime industry's transition towards more sustainable operations.
