Advanced chemical engineering tailored for high-efficiency machinery and automotive assembly lines.
In modern mechanical engineering, thermal management is not merely a utility—it is a critical boundary condition for system efficiency, emissions reduction, and physical asset lifespan. The Nagoya metropolitan region, representing the industrial engine of Aichi Prefecture, stands as one of the world's most concentrated clusters for automotive assembly, precision machining, and heavy aerospace components.
As internal combustion engines (ICE) undergo unprecedented thermal stresses due to downsizing and hybridization, and electric vehicle (EV) battery packs demand exact isothermal zones, the role of high-performance engine antifreeze and industrial coolants has become paramount. Standard glycol formulations no longer suffice. Modern procurement teams require advanced Organic Acid Technology (OAT) and Hybrid OAT (HOAT) variants that guarantee multi-metal protection, cavitation resistance, and operational lifespans exceeding five years under continuous mechanical cycles.
Nagoya's industrial landscape is highly structured around the Toyota ecosystem, aerospace contractors in Toyoyama, and precision machine tool developers in Minami-ku. These diverse sectors require distinct thermal fluid chemistries:
The global chemical industry is facing a dual transition: ecological sustainability and systemic electrification. The key trends reshaping the market include:
Established in 2009 in the industrial heartland of Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. represents the pinnacle of Chinese Lubrication & Coolant Factory 4.0 standards. Operating a state-of-the-art 131-acre manufacturing complex, Longhai has developed a highly integrated supply chain that directly addresses the challenges of just-in-time (JIT) production in Nagoya.
Our manufacturing resilience is built on three core pillars:
Shandong Longhai Lubrication Technology Development Co., Ltd. was established in 2009 and is headquartered in Zibo, Shandong. It is a high-tech enterprise integrating R&D, production, and sales. The company has been deeply involved in the lubricant and coolant industry for more than 15 years, has built a complete industrial chain system, and is committed to providing high-quality lubrication and thermal management solutions for the global industrial and transportation fields.
As a reliable lubricant manufacturer in the industry, Longhai Technology owns its own brand "Century Longhai" and the international strategic cooperation brand British "A Ba" series of products. The products cover diesel engine oil, gasoline engine oil, gear oil, hydraulic transmission oil, anti-wear hydraulic oil, special engine oil for engineering machinery, special oil for natural gas, full synthetic oil, automotive urea solution, antifreeze, special engine oil for motorcycles, industrial oil, automatic transmission oil, and many other lubricant varieties. The brand is insured by PICC China People's Insurance Company.
Longhai Technology has always insisted on innovation-driven development. Its annual R&D investment accounts for more than 5% of its annual revenue. We have established strategic cooperation with many universities and scientific research institutions to continuously optimize lubrication technology and promote industry progress. At present, the company's production base covers an area of 131 acres, with an annual production capacity of 200,000 tons. It is equipped with intelligent production lines and precision laboratories to meet the customized needs of different customers.
The company has passed ISO-9001-2015 quality system certification, 14001 environmental management system certification, 18001 health management system certification. Automatic transmission Mercedes-Benz certification has laid the foundation for the healthy development of the company and the stability of product quality. The company strictly follows international standards and introduces foreign production processes and testing technologies to ensure that the products can still perform excellently under extreme working conditions, helping customers improve equipment efficiency and reduce maintenance costs.
Meeting global specifications with certified production lines and flexible custom packaging services.
We offer fully synthetic and semi-synthetic formulations tailored to vehicle/equipment requirements, climatic conditions or market positioning to meet international standards such as API, ACEA, and Japanese JIS.

Providing direct answers to essential engineering queries and procurement standards in the Nagoya market.
Organic Acid Technology (OAT) utilizes organic inhibitors (such as sebacate and 2-ethylhexanoic acid) without silicates or phosphates. This offers prolonged service life but requires specific sealing materials. Hybrid OAT (HOAT) combines organic acids with a small amount of inorganic inhibitors (typically silicates or phosphates) to provide rapid protective passivation. For Japanese vehicle engines (e.g., Toyota, Honda), non-silicate, phosphate-containing OAT (often called P-OAT) is highly recommended. It complies with JIS K 2234 standards, preventing thermal scaling while maximizing heat dissipation in compact aluminum blocks.
Our manufacturing center in Zibo uses multi-stage deionized water systems (reducing conductivity to <2 µS/cm) to eliminate minerals that cause heat exchanger scaling. Additionally, our high-precision blending lab employs chromatographs to verify additive concentration down to parts-per-million (ppm). This is critical for preventing localized cavity erosion and maintaining high thermal conductivity.
We export our coolants and lubricants in multiple configurations: 1000L IBC totes, 200L steel drums, and flexible customized retail packaging (1L, 4L, 18L). Due to our strategic factory location in Shandong, China, we route shipments through Qingdao Port. Shipping transit times to the Port of Nagoya typically range from 4 to 7 days, allowing us to support JIT logistics requirements for Japanese industrial buyers.
Our global quality insurance, issued by the People's Insurance Company of China (PICC), covers system malfunctions or engine damage proven to be caused directly by formulation defects. This gives international distributors and fleet owners absolute confidence and financial security when replacing OEM fluids with Century Longhai products.
