— Guolin Technology Makes a Brilliant Appearance at the 27th China Environmental Protection Expo

From April 13 to 15, 2026, the 27th China Environmental Protection Expo—the premier event in Asia’s environmental protection sector—was successfully held at the Shanghai New International Expo Center. This edition brought together nearly 2,000 environmental protection companies from around the globe, focusing on cutting-edge areas such as water treatment, solid-waste resource utilization, smart water management, and carbon neutrality, to jointly explore new pathways for high-quality development of the environmental protection industry in the inaugural year of the 14th Five-Year Plan.

As a leading enterprise in China’s ozone industry and the first domestically listed company in the ozone sector (stock code: 300786), Qingdao Guolin Technology Group Co., Ltd. (hereinafter referred to as “Guolin Technology”) made a high-profile appearance with several of its subsidiaries, presenting a comprehensive showcase that encompasses a full range of ozone equipment, a complete industrial-chain technology matrix, and diversified application solutions. This once again underscores the advanced technological capabilities and robust strength of domestically produced ozone equipment.

On the very first day of the event, Guolin Technology proudly clinched the 2026 Shanghai Environmental Expo’s Annual Leading Enterprise Award, instantly becoming the industry’s star attraction and drawing widespread attention at the show.

All-Scenario Solutions Unveiled; Technology Matrix Upgraded Again

As a “barometer” of technology and market trends in the environmental protection industry, China Environmental Protection Expo has consistently focused on the sector’s pain points and emerging development directions. During this year’s edition of the expo, Guolin Technology has centered on core application scenarios—including municipal water treatment, industrial wastewater treatment, high-end manufacturing, healthcare, and space disinfection—to create a dedicated showcase for end-to-end ozone solutions, comprehensively demonstrating its full capabilities—from equipment manufacturing and system integration to engineering applications and intelligent operations and maintenance.

At the exhibition, Guolin Technology, together with its subsidiaries, unveiled a portfolio of core products, including intelligent ozone equipment and integrated system solutions, while also launching a range of innovative offerings such as semiconductor-grade ultra-pure high-concentration ozone generators, PEM electrolysis-based ozone water machines, pharmaceutical-grade high-purity ozone generators, high-precision laboratory ozone equipment, and space disinfection units.

All of the aforementioned products are independently developed based on Guolin Technology’s core proprietary technologies, boasting outstanding advantages such as zero impurity introduction, high purity, exceptional stability, and superior safety. They are precisely tailored to meet the stringent requirements of demanding applications in pharmaceuticals, healthcare, laboratories, and advanced water treatment, providing a one-stop ozone technology solution to address environmental protection and health needs across multiple sectors.

High-Profile On-Site Engagement Fuels Deeper Customer Collaboration

During the exhibition, the Guolin Technology booth enjoyed strong visitor traffic and lively exchanges. The sales team adopted a service model featuring “one-on-one precision matchmaking, in-depth interpretation of comprehensive solutions, and expert technical Q&A” to engage in in-depth discussions with domestic and international clients on topics such as ozone-generation mechanisms, process optimization and upgrades, intelligent O&M systems, and innovative system integration. They shared the company’s technological application achievements in benchmark projects, engineering implementation experience, and customer-service case studies.

This exhibition represents not only a significant opportunity for Guolin Technology to showcase its comprehensive strengths and expand its market footprint, but also a pivotal step in the company’s proactive integration into the environmental protection industry ecosystem and deepening of cross-sector collaboration. Leveraging the Environmental Expo as a platform, Guolin Technology has further strengthened its connections with both upstream and downstream players in the industry, laying a solid foundation for future technological innovation, market expansion, and industrial synergy.

Over three decades of deep cultivation and accumulation have solidified our core competitive edge in the industry.

For more than three decades, Guolin Technology has been deeply committed to the ozone industry. As a pioneer in domestic ozone technology and a key participant in the development of industry standards, the company has consistently upheld technological innovation and serving the nation through industrial advancement as its mission. Driven by independent R&D of core technologies, Guolin has become one of the first domestic manufacturers to achieve breakthroughs in the production of full-range ozone generators—ranging from kilogram-scale to 10-kilogram, 100-kilogram, and even 500-kilogram models—thereby realizing a leap-forward transformation of China’s ozone technology from “catching up” to “leading.”

Leveraging a full-industry-chain R&D and manufacturing system, Guolin Technology has established a complete industrial closed loop that spans “core equipment R&D—system integration design—project implementation—intelligent operation and maintenance services.” With stable product performance, cutting-edge technological capabilities, and extensive project execution experience, Guolin’s products and solutions are widely deployed across municipal, industrial, pharmaceutical, healthcare, and ecological-environmental protection sectors, providing reliable support for key national environmental protection projects and firmly establishing the company as a leading domestic brand in ozone equipment.

Charting a Course for Long-Term Development and Supporting the Nation’s New Journey of Green Transformation

At present, with the in-depth implementation of the “dual carbon” strategy and the accelerated advancement of Beautiful China initiatives, the global environmental protection industry is poised for unprecedented development opportunities, while also placing higher demands on the innovative upgrading and expanded application scenarios of ozone technologies and equipment.
