On April 26, 2025, the "Innovative Products" launch ceremony of China Refrigeration Exhibition was held in Shanghai. Sifang Optoelectronics Co., Ltd. (hereinafter referred to as "Sifang Optoelectronics") has won the "Innovative Product" award at the 2025 China Refrigeration Exhibition, thanks to its independently developed refrigerant leakage monitoring sensor AM4205, which has been recognized by the evaluation experts and stood out from numerous competing products. This honor not only demonstrates the technological strength of Sifang Optoelectronics in the field of refrigerant monitoring, but also reflects the industry's full recognition of its innovative capabilities.

Since 2016, Sifang Optoelectronics has been laying out its presence in the field of refrigerant sensors. With over 20 years of deep accumulation in non dispersive infrared (NDIR) technology, it has successfully developed the AM4205 refrigerant leak monitoring sensor. This product, with its advantages of high detection accuracy, fast response, and long lifespan, can accurately detect various A2L/A3 refrigerants such as R32, R454A, R454B, R454C, R290, etc. It has passed multiple international certifications such as UL and IEC, and has won wide recognition from domestic and foreign customers.

In terms of technological innovation, Sifang Optoelectronics has always adhered to diversified development, horizontally expanded the thermal conductivity and ultrasonic technology routes, and further enriched the product line of refrigerant leakage monitoring sensors to meet the diverse needs of different customers. And based on a comprehensive sensor technology platform, Sifang Optoelectronics has vertically developed a complete set of refrigerant leakage monitoring solutions, including refrigerant laboratory research equipment (compliant with UL/IEC Appendix LL and Appendix MM testing requirements), air conditioning/refrigerant production line environmental refrigerant leakage detectors, refrigerant leakage monitoring sensors for air conditioning, and refrigerant recovery. At present, it can cover R454B, R454C, R1234YF, R1234ZE, R290, CO₂、NH₃By testing various refrigerants, the service scope extends from household/commercial refrigeration equipment to new fields such as industrial refrigeration and cold chain logistics.

Winning the "Innovative Product" award at the 2025 China Refrigeration Exhibition is a recognition of the excellent product performance of Sifang Optoelectronics, and also marks the industry's recognition of Sifang Optoelectronics' strength in refrigerant leakage monitoring. In the future, Sifang Optoelectronics will continue to increase research and development investment, continuously improve technological innovation capabilities, and strive to launch more high-quality products that meet market demand to ensure the safe operation of refrigeration systems.
