The heavy trucks carrying cargo from the Port of Djibouti to the Ethiopian hinterland face grueling climbs. Our Cummins ISX15 and QSX15 oil cooler cores are engineered to handle the massive heat rejection required by these engines during long-haul ascents.
Addis Ababa's skyline is a testament to the construction boom. Excavators and cranes from brands like Sany, CAT, and Komatsu rely on our hydraulic oil coolers. Our aluminum plate-fin cores provide superior cooling density in compact spaces, ideal for modern urban construction machinery.
At Zhejiang Rock Auto Co., Ltd., our manufacturing process involves advanced vacuum brazing technology. Unlike traditional mechanical expansion, vacuum brazing creates a molecular bond between the fins and the tubes, resulting in significantly higher thermal conductivity and structural integrity. For the Ethiopian market, we also offer Brass Core Dust Filter Radiators, which are specifically designed for environments with high airborne particulate matter—common in Ethiopian agricultural and mining sites.
Established in 2007, Zhejiang Rock Auto Co., Ltd. has been a leading manufacturer, exporter, and supplier of high-performance auto cooling system components. We specialize in producing a wide range of automotive cooling solutions, including radiator tubes, intercooler tubes, oil cooler tubes, as well as radiators, intercoolers, and oil coolers.
With more than 15 years of industry experience, we have earned a reputation as a pioneer in the design and manufacturing of aluminum-based cooling products. We are committed to providing high-quality, cost-effective, and innovative solutions that meet the rigorous demands of our global customers.
Our state-of-the-art manufacturing facility is equipped with advanced technologies, including Brazing Furnaces, Fin Machines, and Core Assembly Machines. We are proud to be ISO/TS 16949 certified, ensuring every oil cooler core we ship to Ethiopia meets international automotive standards.
