From April 13 to 15, 2026, the 27th China Environment Expo, a benchmark event in Asia's environmental protection sector, was successfully held at the Shanghai New International Expo Centre. This year's expo brought together nearly 2,000 environmental companies from around the world, focusing on cutting-edge fields such as water treatment, waste resource utilization, smart water services, and carbon neutrality, to explore high-quality development pathways for the environmental protection industry at the start of the "15th Five-Year Plan" period.

As a leading enterprise in China's ozone industry and the first listed company in the domestic ozone sector (Stock Code: 300786), Qingdao Guolin Technology Group Co., Ltd. ("Guolin Technology") made a prominent appearance at the expo together with several of its subsidiaries. By presenting a full range of ozone equipment, a whole-industry-chain technology matrix, and diverse scenario-based solutions, Guolin Technology once again demonstrated the technological sophistication and core strength of domestically manufactured ozone equipment. On the very first day of the expo, Guolin Technology won the "2026 Shanghai Environment Expo Annual Leading Enterprise Award," becoming a focal point of industry attention.

Comprehensive Scenario-Based Solutions Debut with an Upgraded Technology Matrix

As a bellwether of environmental technology and markets, the China Environment Expo consistently focuses on industry pain points and development trends. During this year's expo, Guolin Technology closely addressed core application scenarios including municipal water treatment, industrial wastewater treatment, high-end manufacturing, healthcare, and space disinfection. The company created a one-stop ozone solution display zone, comprehensively showcasing its complete capabilities ranging from equipment manufacturing to system integration, from engineering application to intelligent operation and maintenance.

At the expo, Guolin Technology, together with its subsidiaries, prominently featured core products such as intelligent ozone equipment and supporting integrated systems. Concurrently, the company released innovative achievements including a semiconductor-grade ultra-pure high-concentration ozone generator, a PEM electrolytic ozone water machine, a medical-grade high-purity ozone generator, a high-precision experimental ozone device, and space disinfectors. These products, developed independently based on Guolin Technology's core technologies, offer outstanding advantages such as no impurity introduction, high purity, high stability, and high safety. They can be precisely tailored to demanding application scenarios like pharmaceuticals, healthcare, laboratories, and high-end water treatment, providing one-stop ozone technology solutions for environmental protection and health needs across various sectors.

High On-Site Engagement, Deepening Customer Exchange and Cooperation

During the expo, Guolin Technology's booth attracted significant traffic and lively discussions. The sales team adopted a service model of "one-on-one precise matching, in-depth interpretation of total solutions, and professional answers to technical questions," engaging in thorough exchanges with domestic and international customers. Discussions covered ozone mechanism research, process optimization and upgrading, intelligent operation and maintenance systems, and system integration innovations. The team also shared the company's technological application results, engineering implementation experience, and customer service cases from benchmark projects.

This participation was not only an important opportunity for Guolin Technology to demonstrate its comprehensive strength and expand its market presence but also a key initiative to actively integrate into the environmental protection industry ecosystem and deepen industrial collaboration. Through the platform of the Environment Expo, Guolin Technology further strengthened its connections across the industry chain, laying a solid foundation for subsequent technological innovation, market expansion, and industrial synergy.

Over Thirty Years of Deep Cultivation, Building Core Industry Competitiveness

With over three decades of deep cultivation in the ozone field, Guolin Technology, as a pioneer in domestic ozone technology and a participant in formulating industry standards, has always been driven by the mission of technological innovation and serving the nation through industry. Propelled by independent research and development of core technologies, the company became the first domestic enterprise to break through the manufacturing technology for a full series of ozone generators, including kilogram-scale, 10-kilogram-scale, 100-kilogram-scale, and 500-kilogram-scale units, achieving a leapfrog development of domestic ozone technology from "following" to "leading."

Relying on its whole-industry-chain R&D and manufacturing system, Guolin Technology has established a complete industrial closed loop covering "core equipment R&D — system integration design — engineering implementation — intelligent operation and maintenance services." With stable product performance, leading technical levels, and extensive project implementation experience, Guolin Technology's products and solutions are widely applied in municipal, industrial, pharmaceutical, healthcare, ecological, and other fields. They provide reliable support for key national environmental protection projects, solidly establishing the brand image of a leading domestic ozone equipment manufacturer.

Committed to Long-Term Development, Supporting the National Green Transformation

At present, as the "dual carbon" strategy is deeply advanced and the Beautiful China initiative accelerates, the global environmental protection industry is facing unprecedented development opportunities. This also places higher demands on the innovation, upgrading, and scenario expansion of ozone technology and equipment.

As a leading enterprise in the ozone field, Guolin Technology will continue to leverage its core ozone technology as a foundation, driven by innovation and supported by high-quality services. The company will continuously expand application scenarios and upgrade solutions, contributing to the sustained improvement of the ecological environment with more advanced ozone technologies and more comprehensive solutions, and playing its part in green, low-carbon development and the construction of a Beautiful China.
