XINZ's Distributed Product, CASRI Fuel Water Detector Wins Excellence Award At The 25th China Patent Awards
Sep 19, 2025| The CASRI Fuel Water Detector has been honored with the Excellence Award at the 25th China Patent Awards. This esteemed accolade, one of China's most prestigious intellectual property honors, recognizes the product's significant innovation and substantial utility within the critical field of aviation fuel safety.
The award-winning CASRI Fuel Water Detector is a rapid and reliable solution for identifying trace water in jet fuel. It utilizes a patented reagent technology that produces a clear and immediate color change upon contact with water, enabling aviation maintenance engineers and fuel handlers to perform essential on-the-spot quality checks and prevent the use of contaminated fuel.
Aviation fuel quality is fundamental to flight safety, and even trace amounts of free water can become a "hidden killer" in fuel systems. At high altitudes and low temperatures, this water may freeze, obstruct fuel lines, and potentially cause catastrophic engine failure. Traditional detection methods often rely on complex equipment, specialized facilities, and highly trained personnel, making them time-consuming and impractical for rapid on-site testing.
To tackle this challenge, the research team developed the CASRI Fuel Water Detector-an innovative test paper that simplifies and accelerates free water detection. By passing just 5ml of fuel through the test paper, users can obtain clear visual results within two minutes based on color changes, indicating whether free water content exceeds safety limits. The product's preparation integrates cutting-edge advancements in materials science and chemical engineering, overcoming technical hurdles related to sensitivity, stability, and anti-interference capabilities.
Complemented by a compact and portable detection device, the CASRI detector is adaptable to various operational environments such as aprons and fuel depots. It supports both routine inspections and emergency assessments, delivering rapid and accurate results that significantly improve fuel quality management efficiency.
This innovation has gained recognition from leading international standardization bodies, including ASTM, EI, IATA, JIG, and the Japan Petroleum Institute, and has been exported to countries such as Italy and Japan. By providing a reliable and accessible solution for on-site free water detection, the CASRI Fuel Water Detector effectively mitigates operational risks and contributes to global aviation safety.
Key advantages of the product include:
High Sensitivity: Effectively detects minute traces of water.
Immediate Results: Provides visual results within seconds for quick decision-making.
Ease of Use: Designed for simple operation with minimal training required.
Portability: Ideal for field use at airports, in hangars, and at fuel depots.
This national award, jointly administered by the China National Intellectual Property Administration (CNIPA) and the World Intellectual Property Organization (WIPO), further validates the product's excellence and is anticipated to drive its adoption across the global aviation sector.
