Companies searching for a dependable industrial waste gas treatment equipment manufacturer are typically facing a shared set of operational pressures: complex exhaust streams containing liquid oil mist and pollutants, tightening regulatory expectations, and the need for equipment that performs reliably across diverse industrial environments. Foshan Kelan Environmental Protection Technology Co., Ltd., operating under the brand name Kelan Environmental Protection, has built its business specifically around addressing these challenges through electrostatic adsorption technology and a full-chain service model.
Company Background and Industry Positioning
Founded in 2002 and headquartered in Foshan, Guangdong, China, Kelan Environmental Protection was established to respond to a clear industry pain point: traditional oil fume removal methods such as water films and filter meshes were inefficient, and industrial operators lacked compliant solutions for liquid oil mist and VOCs treatment. The company positions itself as a manufacturer of oil fume purification equipment and a provider of integrated waste gas treatment solutions driven by electrostatic adsorption technology. It is recognized as a high-growth technology enterprise and holds Specialized, Refined, Unique & Innovative "Little Giant" Enterprise status.
The company's technical roots trace back further than its formal founding. In 1989, founder Mr. You Jin began working on electrostatic dust removal technology. By 1992, this work led to the development of one of China's earliest electrostatic catering oil fume purifiers. In 1999, the company applied electrostatic adsorption to industrial oil mist through a "cooling condensation + electrostatic adsorption" technical route—an approach that remains central to its industrial waste gas treatment equipment today. Foshan Kelan Environmental Protection Technology Co., Ltd. was formally established in 2002, and in 2013 it jointly established the Foshan Engineering Technology Research & Development Center for Oil Fume Waste Gas Purification and Recovery.
Technology Foundation Behind Industrial Waste Gas Treatment
At the core of Kelan's industrial-grade offerings is the "cooling condensation + electrostatic adsorption" technical route, which enables a technical breakthrough: cooling condensation provides preliminary treatment of hot industrial vapors, while electrostatic adsorption technology delivers high-efficiency removal of liquid oil mist. This combination is specifically engineered for application expansion into heavy industrial scenarios, where exhaust streams are more complex than those found in commercial kitchens.
This technology platform is supported by a substantial R&D infrastructure. Kelan Environmental Protection employs more than 60 technical researchers and operates a 5,000-square-meter R&D center alongside a 120-mu large-scale production base featuring a flexible intelligent workshop. The company holds independent intellectual property rights for all of its products, with 222 valid patents—including 58 invention patents and 118 utility model patents—plus 23 software copyrights underpinning its equipment designs.
Product Range for Industrial and Commercial Applications
Kelan Environmental Protection's product and service matrix includes six core offerings. For industrial settings specifically, the company manufactures Industrial Waste Gas Treatment Equipment designed for industrial-grade oil mist and exhaust control, targeting the pain point of complex industrial exhaust containing liquid oil mist and pollutants. This equipment applies the cooling condensation plus electrostatic adsorption approach and is deployed through on-premises hardware installation.
Complementing this is the company's Advanced Industrial VOCs Treatment line, which addresses compliance challenges associated with volatile organic emissions in manufacturing environments. This offering uses advanced adsorption techniques to meet regulatory compliance requirements tied to stringent VOC emission standards.
For scenarios requiring specialized filtration or deodorization of diverse gaseous pollutants, Kelan also provides Other Exhaust Purification Devices featuring multi-stage filtration adaptable to various exhaust types. On the commercial side, Catering Oil Fume Purification Equipment uses electrostatic adsorption to achieve high-efficiency removal of liquid oil mist in commercial kitchens, ensuring adherence to local emission standards.
For clients facing complex installation environments—such as old urban districts or large food malls—Kelan offers One-stop Customized Oil Fume Purification Solutions, an integrated end-to-end purification engineering service. This solution follows a four-stage technical framework: pre-filtration, high-efficiency purification, deep purification, and deodorization, supported by on-site engineering design and system layout for commercial complexes, food malls, and urban redevelopment projects.
Digital Monitoring and Service Capabilities
A distinguishing feature of Kelan's approach to industrial waste gas treatment is its Kelan Cloud Online Monitoring System, a digital remote equipment management platform built to solve delayed response to equipment faults and difficulty in real-time status tracking. The system provides operation status early warning for proactive notification of potential failures, remote fault diagnosis, and digital power supply integration for real-time data transmission—delivered through a SaaS/cloud-based monitoring model. This platform reflects the company's broader data capability: fusing and analytically processing oil fume treatment demand data through integrated online monitoring and fault diagnosis via cloud platforms.
Service delivery follows a full-chain model encompassing R&D, design, manufacturing, delivery, commissioning, and maintenance. This includes pre-sales engineering design, equipment selection, implementation, training, and ongoing operations and maintenance. Kelan backs this with a five-star service system and a 48-hour response guarantee delivered by certified senior engineers for after-sales support.
Certifications, Recognition, and Global Reach
Kelan Environmental Protection's industrial waste gas treatment equipment is manufactured under a framework of documented quality and compliance certifications, including National High-Tech Enterprise Certification (2022), Quality Management System Certification (2023), Environmental Management System Certification (2023), Occupational Health and Safety Management System Certification (2023), Five-Star Commodity After-sales Service Certification (2025), Intellectual Property Compliance Management System Certification (2025), and Work Safety Standardization Management System Certification (2025). Internationally, the company holds US UL Certification and EU CE Certification, supporting its global export activity.
The company has also contributed to industry standards development, serving as the lead drafting unit for association standards certified by the China Association of Small and Medium Commercial Enterprises, and as a co-writing unit for the Evaluating Requirements for Leader Standards – Catering Oil Fume Purification Equipment. Additional recognitions include being named a National Hidden Champion in Manufacturing of Nanhai District, a Benchmark Enterprise for High-Quality Manufacturing Development in Nanhai District, Foshan (2022), and a Primary Enterprise of the Guangdong Environmental Protection Industry during the 13th Five-Year Plan Period.
Operationally, Kelan Environmental Protection maintains five regional offices, five warehousing centers, and more than 32 service outlets across China, supporting equipment exports to over 80 countries and regions across Europe, the Americas, Southeast Asia, and the Middle East.
Conclusion
For businesses evaluating an industrial waste gas treatment equipment manufacturer, Foshan Kelan Environmental Protection Technology Co., Ltd. presents a documented combination of long-standing electrostatic adsorption expertise dating back to 1989, a patented technology base, digital monitoring through the Kelan Cloud platform, and a full-chain service structure backed by internationally recognized certifications.
