About Us

Jining Denaichi New Energy Co., Ltd., situated within the Wenshang Chemical Industry Park in Jining City, Shandong Province, is a diversified, leading-edge enterprise specializing in the comprehensive integration of lubricant technology R&D, product manufacturing, technical services, and sales.

Established in 2016, the company occupies a total area of ​​over 100 mu (approximately 6.7 hectares) and currently employs a workforce of more than 100 individuals. The company's Phase I project has been successfully completed and features one modern, intelligent blending and filling workshop, as well as two intelligent, multi-tier warehouses for packaging materials. The total built-up area spans 21,000 square meters, comprising 10,000 square meters for production, 8,000 square meters for warehousing, and 5,000 square meters for office space.

As a comprehensive petrochemical enterprise with years of deep-rooted experience in the lubricant sector, the company possesses robust developmental capabilities. It maintains a standing storage capacity of over 15,000 tons for base oils, over 2,000 tons for additives, and over 10,000 tons for finished lubricant products, with an annual production capacity exceeding 100,000 tons across various types of lubricants and fluid products.

The company has successfully obtained numerous relevant certifications, including ISO 9001 (Quality Management), ISO 14001 (Environmental Management), IATF 16949 (Automotive Quality Management), HSE (Health, Safety, and Environment Management), ISO 45001 (Occupational Health and Safety Management), and the Quality Management System Certification for Weapon Equipment. Furthermore, the company's products have currently secured certification from the American Petroleum Institute (API). The company's lubricant blending workshop now employs a world-leading, fully automated DCS (Distributed Control System) for intelligent blending control. Through database-driven management and fully automated, high-response control valves, the blending process has achieved a state of near-total "unmanned" precision operation. High-precision data sensors transmit real-time operational data from the blending reactors to an intelligent, digitized control console, enabling continuous, real-time monitoring of the entire lubricant production lifecycle. This advanced system has elevated the first-pass success rate of lubricant blending to over 95%, thereby not only boosting production efficiency but also further guaranteeing product quality, while simultaneously making a meaningful contribution toward energy conservation, emission reduction, and green development. The company currently operates over 20 automated and intelligent lubricant filling production lines, capable of achieving rapid and precise filling for various specifications ranging from 1L, 2L, 4L, 16L, 18L, and 200L to 1000L. This capability allows us to meet the demands of large-scale, high-volume production while simultaneously ensuring personalized and customized lubricant manufacturing services, thereby truly putting the philosophy of "Customer First" into practice.

To guarantee product performance and quality, the company invested over 10 million RMB to establish the Denachi Lubrication Technology R&D Center. We have successively introduced more than 100 pieces of advanced domestic and international lubricant testing equipment, covering the research, development, and testing of eight major product categories, including engine oils, hydraulic oils, transmission fluids, gear oils, industrial oils, automatic transmission fluids, and antifreeze. The company currently employs a dedicated team of over 10 R&D professionals and holds more than 20 invention patents; notably, several of these inventions have received national, provincial, and municipal-level awards for scientific and technological innovation, further solidifying the enterprise's competitive technical advantage.
Currently, the company manages renowned lubricant brands such as "Dayu" and "Weinaili." Our product portfolio comprises seven major series-including construction machinery oils, commercial vehicle diesel engine oils, gasoline engine oils, industrial oils, specialty oils, metalworking fluids, and antifreeze-encompassing over 1,000 distinct specifications and models. Guided by the development philosophy of "Technology as the Driving Force, Quality as the Key to Survival," the company has forged global strategic partnerships with internationally renowned suppliers of base oils and additives-including Afton, Infineum, SsangYong (Korea), and CPC (Taiwan)-as well as strategic alliances with major domestic enterprises such as Sinopec, CNPC, XCMG, Shacman, Beiben Trucks, Chitian Auto, Longmay Group, and Yankuang Group. Through superior lubricant product solutions, we empower domestic and international enterprises to reduce costs, enhance efficiency, and elevate their overall operational capabilities.

In 2020, the company took the initiative to set its sights on the global market and actively engage in international competition. To date, our export operations have expanded to cover over 20 countries and regions, and we have successfully established four overseas sales distribution centers located in Russia, South Africa, Kazakhstan, and Singapore. With an ever-expanding network of partners, Denairch has entered a new era of accelerated growth; the company's Phase II expansion project is currently being actively planned and developed.
Looking ahead, Jining Denairch New Energy Co., Ltd. remains driven by the ambitious vision of "Quality First, Lubricating the World." Leveraging intelligent manufacturing facilities and cutting-edge lubrication technologies, the company will continue to supply the market with highly reliable lubrication products and services-utilizing its renowned lubricant brand to propel corporate growth forward and achieve new heights of excellence.
