ABOUT US
Focuses on the management and operation of industrial volatile organic waste gas, and is committed to providing customers with full life cycle system solutions with high purification efficiency and low operational energy consumption.
The manufacturing base of Suzhou Kelan Environmental Technology Co., Ltd. is located in Liyang City, Jiangsu Province. At present, we have more than 30,000 square meters of standard production plant, over 5,000 square meters of office facilities and supporting R & D space, nearly 100 sets of various complete sets of R & D and production equipment, and a sound team of technical personnel with a production and testing center.
We have established a perfect quality management system, from the inspection of raw materials to the factory testing of finished products, each link has strict quality control, all equipment is assembled in the factory, factory pre-commissioning, only products that have passed the FAT test will be sent to the customer site to maximize ensure that customers get the best experience. To ensure high-precision manufacturing and efficient production, we use advanced production equipment such as plasma cutting machines, CNC machines, automatic welding machines, etc. All equipment is regularly maintained and upgraded to always maintain the best condition. Through the introduction of advanced production equipment and optimization of production processes, we have improved our production efficiency and can flexibly adjust our production schedule according to market demand and customer orders to ensure quick response and on-time delivery.
We always adhere to the concept of green development, and our factory has been constructed as a green factory in Changzhou City, which has passed the environmental management system certification, energy management system certification, intellectual property management system certification, occupational health and safety management system certification, quality management system certification, and greenhouse gas emission verification. At present, there is a photovoltaic power generation facility in the plant. Under the national goal of "carbon peak, carbon neutral", CN-KELAN will continue to implement clean technology transformation and take the road of high-quality development. We promise to pay more attention to environmental protection and sustainable development while pursuing economic benefits, and to further enhance green productivity and create more value for the society through refined management and waste reduction.
