Product Introduction: SFAAENG-578 Full Aluminum Radiator for Hitachi 350 Excavator
SFAAENG-578 is a high-performance full-aluminum radiator specially developed for Hitachi 350 heavy excavators, serving as the core cooling component for large-scale construction machinery. This model fits perfectly for Hitachi 350 equipment widely applied in mining sites, highway construction, municipal projects and quarry operations. It features standard industrial dimensions: header size 450×124 and an ultra-thick 1030×428×100 cooling core, equipped with dual Φ60 coolant ports that fully match the original pipeline layout of Hitachi machines. The matched port size ensures smooth coolant circulation without flow resistance, eliminating engine overheating risks during long-hour continuous heavy-load operation.
The biggest highlight of this radiator is its full-aluminum integrated structure paired with exquisite, precise manufacturing craftsmanship. Unlike mixed copper-aluminum radiators from ordinary suppliers, we adopt high-purity anti-corrosion aluminum alloy for every component, including upper and lower water headers, cooling tubes, dense fins and side brackets. All parts are formed via precision CNC stamping, with neat, smooth edges free of rough burrs or uneven cut surfaces. Automated full brazing technology is adopted for all welding joints; solder lines are tight, uniform and seamless, presenting fine workmanship far superior to generic aftermarket radiators. Such delicate details effectively avoid hidden water leakage points and greatly improve the overall tightness of the cooling system.
We adopt raw material specifications stricter than the average industry standard, bringing remarkable structural strength and shock resistance. The 100mm thick core is built with reinforced thick tubes and rigid fins, which can withstand constant strong vibration and bumping on rugged construction ground without deformation, bending or cracking. A complete anti-rust oxidation coating is applied on all aluminum surfaces, forming a dense protective film to resist erosion from mud, dust, rain and coastal salt fog. The outstanding anti-corrosion performance extends the product’s service life significantly, helping machinery owners cut down frequent replacement and maintenance costs.
A complete multi-stage quality inspection system covers all production procedures. Each finished SFAAENG-578 radiator undergoes high-pressure air tightness testing, heat dissipation efficiency detection and full-size dimension calibration before delivery. Supported by our abundant mold resources, advanced automated production equipment and senior workers with years of heat exchanger manufacturing experience, every batch maintains consistent exquisite appearance and stable performance.
We provide personalized customization service for this Hitachi radiator as requested, such as adjusting fin density or upgrading anti-corrosion coating for extreme harsh working conditions. With full-aluminum premium materials, delicate production details, powerful cooling capacity and long service life, SFAAENG-578 has become a reliable aftermarket replacement choice for global Hitachi machinery dealers and repair workshops. We sincerely invite worldwide partners to place bulk orders and visit our factory to inspect our full-aluminum production and strict quality control process.
