Engineered to exceed OEM specifications and ensure maximum mechanical protection under fluctuating operating temperatures.
The San Francisco Bay Area represents one of the most technologically advanced and environmentally regulated markets in the world. For commercial transit authorities, heavy-duty logistics firms operating near the Port of San Francisco, and data centers in Silicon Valley, managing heat is a critical operational parameter.
Unlike regions with extreme sub-zero winter temperatures, the coastal climate of Northern California requires antifreeze/coolants engineered heavily for high-efficiency thermal dissipation, cavitation protection, and long-term corrosion prevention. High-mileage delivery vans operating in dense urban gradients, hybrid bus transit fleets, and container-handling machinery require chemical formulations that remain stable over extended drain intervals.
Furthermore, California's strict regulatory framework under the California Air Resources Board (CARB) and local water quality controls demands that coolant exporters and suppliers maintain flawless chemical safety standards. Ethylene glycol (EG) and non-toxic Propylene glycol (PG) formulations must comply with ASTMs like ASTM D3306 for light-duty engines and ASTM D6210 for heavy-duty applications.
Deploying specialized coolant and lubrication formulations leads to measurable enterprise cost reductions:
Established in 2009 and headquartered in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. is a high-tech enterprise integrating R&D, production, and international sales. With over 15 years of industry leadership, we have built a fully integrated supply chain designed to export high-grade industrial lubricants, engine oils, and advanced antifreeze solutions directly to major global hubs, including the San Francisco Bay Area.
Under our proprietary brand "Century Longhai" and our strategic international brand partnership British "A Ba" series, our catalog spans synthetic motor oils, heavy-duty gear oils, hydraulic transmission fluids, turbine oils, and customized vehicle urea solutions. To guarantee complete peace of mind, our entire product range is insured globally by PICC (People’s Insurance Company of China), backed by comprehensive product liability protection.
Our manufacturing facility spans over 131 acres, utilizing state-of-the-art automated blending lines to deliver an annual production capacity of 200,000 tons. Our precision laboratories ensure every batch meets strict ISO standards.
Leveraging advanced automation to guarantee continuous supply and ultra-precise blending accuracy for bulk fluid orders.
Massive production infrastructure guarantees consistent product supply even during global logistics bottlenecks.
Advanced automatic filling systems achieve high-precision filling tolerances between 1‰ and 2‰.
Continuous technological iterations to meet evolving automotive emission and thermal management trends.
Aligning industrial chemistry with specific localized thermal dissipation needs.
Liquid-cooling technologies for high-density compute environments in Silicon Valley. Our formulations protect copper heat exchangers from galvanic corrosion and dynamic cavitation.
Engineered coolants for maritime auxiliary generators and port-side cargo handling equipment. Excellent corrosion inhibition in humid, high-salinity marine environments.
Extended life formulations for long-haul fleet trucks and municipal commuter buses, minimizing cooling system maintenance and ensuring consistent system pressure.
Quality is the lifeblood of chemical engineering. Shandong Longhai Lubrication has instituted a strict quality management system certified under ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018. Our automatic transmission and specialty fluids have passed rigorous evaluations, including official Mercedes-Benz approvals.
By utilizing high-grade imported additives and premium synthetic base oils, our formulations are optimized for extreme thermal stability. Every bulk shipment destined for export undergoes strict gas chromatography, viscosity testing, and reserve alkalinity tests in our central lab.

Submitting batch samples for lab confirmation to assure safety compliance.
High-efficiency manufacturing, automated packaging, and global export shipping to San Francisco ports.
With the rapid adoption of electric buses and commercial utility vehicles in California, the role of cooling fluids is shifting. EV motors and high-voltage battery packs require dielectric heat transfer fluids with low electrical conductivity and excellent thermal capabilities to prevent thermal runaway.
Shandong Longhai's engineering department is actively designing next-generation formulations to meet these future requirements. By combining low-viscosity bases with anti-foaming chemistries, our development roadmap prepares local distributors for future commercial fleet standards.
Traditional glycol-based coolants are undergoing a bio-based transition. Propylene glycol, derived from bio-renewable sources, is increasingly requested by municipalities aiming to reduce environmental footprints.
Our future focus centers on Phosphate-free and Silicate-free organic acid technology (OAT), minimizing environmental hazard potential without compromising the critical scaling and cavitation protection required by aluminum-alloy engines.
