High-efficiency formulations engineered to survive high ambient temperatures and heavy structural loads.
Ethiopia is undergoing a rapid industrial transformation, powered by massive infrastructure investments, expanding industrial zones (such as Hawassa, Bole Lemi, and Adama), and a burgeoning logistics corridor connecting Addis Ababa to the Port of Djibouti. However, East Africa’s geographic and climatic variations pose major engineering hurdles. Fleet operators and plant managers struggle with high elevations in the central highlands, where lower atmospheric pressures affect engine cooling efficiencies, combined with extreme heat in lowland basins like the Afar and Rift Valley regions.
Standard engine coolants frequently fail under these localized conditions. The combined stress of thin altitude air and tropical ambient heat accelerates coolant oxidation, causing rapid additive depletion, cylinder liner cavitation, and severe radiator scaling. For modern heavy-duty diesel generators, heavy-load freight trucks, and industrial machinery, using a highly stabilized, high-boiling-point antifreeze formulation is critical. It prevents unexpected downtime and avoids catastrophic thermal failures.
Globally, the industrial cooling and thermal management sector is transitioning from traditional Inorganic Additive Technology (IAT) to highly stable Organic Acid Technology (OAT) and Hybrid Organic Acid Technology (HOAT). Modern formulations eliminate phosphates, silicates, and borates, which tend to precipitate and form abrasive scales under high-temperature cycles. Eliminating these minerals is particularly crucial for the Ethiopian market, where access to pure demineralized water for coolant dilution can be limited in remote agricultural and mining operations.
Shandong Longhai Lubrication Technology Development Co., Ltd. addresses this need by supplying heavy-duty, long-life antifreeze products tailored for high-temperature stability and superior heat transfer. By implementing advanced organic acid inhibitor systems, our coolants offer up to 6 years or 600,000 kilometers of protection, ensuring optimal heat dissipation even under relentless operational profiles.
Heavy freight trucking along the steep, hot Djibouti-Addis corridor requires antifreeze with superior boiling protection and cavitation control to prevent diesel engine cylinder liners from pitting.
Earthmoving machinery deployed in major infrastructure developments requires heat-stable coolant that resists scale accumulation and ensures continuous duty cycles without thermal clogging.
Continuous-load backup generators running in manufacturing zones require high-purity OAT coolants to prevent radiator corrosion and sustain continuous power generation.
Established in 2009 in Zibo, Shandong, Shandong Longhai Lubrication Technology Development Co., Ltd. has spent over 15 years developing high-tech lubrication and thermal management solutions. We manage a fully integrated industrial ecosystem, delivering top-tier performance to industrial and automotive clients worldwide.
Under our flagship brand "Century Longhai" and our international strategic brand British "A Ba", we formulate a comprehensive range of products. These include diesel and gasoline engine oils, hydraulic transmission fluids, heavy-duty gear oils, automatic transmission fluids, and advanced long-life antifreeze. To ensure maximum operational reliability, all products are fully insured by the People's Insurance Company of China (PICC).
Investing heavily in technological innovation to build durable defense systems for global machinery.
Our intelligent blending facility utilizes micro-metered component feeding to maintain high formulation consistency. The automated filling lines operate with a metering precision of 1‰-2‰. This design achieves a 20% to 35% speed increase compared to conventional packing lines, enabling rapid export order fulfillment and consistent delivery schedules for our African distribution partners.
Fully certified under ISO-9001-2015 (Quality), ISO-14001 (Environment), and ISO-45001/18001 (Occupational Health). Our lubricants hold major international approvals, including Mercedes-Benz certifications.
Each batch is tested under simulated high-temperature, high-pressure environments, ensuring that equipment operating in harsh terrains, such as Ethiopian dry plains and deep mines, remains protected against wear.
We develop specific formulations adjusting boiling points, freezing points, and anti-corrosion additives to match the distinct regional demands of our East African buyers.
A seamless, structured process from custom laboratory formulation to final delivery at the Port of Djibouti.

Organic Acid Technology (OAT) coolants contain specialized organic corrosion inhibitors that provide much longer service lives compared to Inorganic Additive Technology (IAT) fluids. Traditional IAT coolants rely on silicates and phosphates that deplete rapidly and can form abrasive mineral scales when mixed with local hard water. This scaling acts as an insulating barrier, reducing heat transfer and causing overheating. Our OAT formulations contain no inorganic minerals, ensuring clean heat exchange surfaces and long-term protection against rust and cavitation under heavy loads.
At elevations above 2,000 meters, the ambient air pressure is significantly lower, which reduces the boiling point of open water and low-pressure cooling systems. This makes the engine highly vulnerable to localized boiling and coolant loss. Using a premium Ethylene Glycol-based antifreeze increases the boiling point of the coolant mixture. When combined with a properly pressurized radiator cap, this keeps the fluid in a liquid state, preventing steam pockets and maintaining efficient heat dissipation.
Yes. We customize our antifreeze formulations based on our clients' local climate conditions. For tropical regions like the Afar lowlands, we adjust the glycol-to-water ratio to prioritize heat transfer and boiling protection. Conversely, for high-altitude zones with cold nights, we ensure adequate freeze protection while maintaining maximum corrosion inhibition.
We regularly ship products to East Africa via the Port of Djibouti, where cargo is transferred to the main road network leading to Addis Ababa. We package our liquids in heavy-duty HDPE drums, IBC totes, or flexibags. All export containers are tightly secured to prevent shifting and handle the mechanical stresses of overland transit across challenging terrains.
Our plant operates an advanced quality control laboratory. Every batch of lubricants and coolants undergoes comprehensive testing. We check physical and chemical metrics, including kinematic viscosity, boiling point stability, pH balance, and corrosion inhibition. We issue detailed Certificate of Analysis (COA) reports with every shipment to ensure compliance with global standards, including ASTM and API specifications.
