Product Introduction: SFAAENG-595 Full Aluminum Radiator for Komatsu 400-7 Excavator
SFAAENG-595 is a premium full-aluminum radiator tailor-made for Komatsu 400-7 excavators, serving as the core heat exchange component for heavy-duty construction machinery widely used in mining, highway construction, quarry sites and large municipal projects. It comes with standardized matched dimensions: header size 490×124 and an extra-thick 1180×468×100 cooling core. The radiator is fitted with multi-caliber ports including dual Φ60 main coolant interfaces, a Φ25 auxiliary connector and a small Φ8 vent hole, which fully match the original pipeline layout of Komatsu 400-7 equipment. Perfect size and port matching allows direct bolt-on installation without any cutting or modification, effectively stabilizing engine temperature and avoiding overheating shutdowns under long-term continuous heavy-load operation.
Its core highlight lies in the integrated full-aluminum structure paired with ultra-exquisite manufacturing craftsmanship. Unlike mixed copper-aluminum radiators from ordinary manufacturers, we adopt high-purity anti-corrosion aluminum alloy for every component, including upper and lower water headers, cooling tubes, reinforced fins and side mounting plates. All parts are shaped by precision CNC stamping, with smooth, burr-free edges and consistent wall thickness. Automated seamless brazing technology is applied to all welding joints; solder lines are compact, uniform and free of tiny gaps, showing far finer workmanship than generic aftermarket radiators. Such meticulous details eliminate hidden leakage points and greatly strengthen the overall tightness of the cooling system.
We adopt raw material specifications higher than general industrial standards, delivering outstanding structural rigidity and shock resistance. The 100mm thick core is equipped with thickened tubes and sturdy dense fins. Komatsu 400-7 excavators often work on bumpy, rugged ground and generate persistent engine vibration; our robust core structure resists bending, deformation and cracking even after years of high-intensity operation. A full anti-rust oxidation coating covers all aluminum surfaces, forming a dense protective film to resist corrosion caused by mud, mineral dust, rain and coastal salt fog. Superior anti-corrosion performance greatly extends service life and reduces customers’ frequent replacement and maintenance costs.
A complete multi-stage quality inspection system runs through the whole production process. Each finished SFAAENG-595 radiator undergoes high-pressure air tightness testing, heat dissipation performance testing and full dimensional calibration before shipment. Supported by our abundant mold resources, advanced automated production equipment and senior skilled workers with rich heat exchanger manufacturing experience, every production batch maintains consistent exquisite appearance and stable cooling performance.
We provide flexible customized optimization for this Komatsu radiator upon customer demands, such as adjusting fin density or upgrading anti-corrosion coatings for extreme harsh working environments. With full-aluminum premium materials, delicate production details, powerful heat dissipation capacity and long service life, SFAAENG-595 has become a reliable aftermarket replacement choice for global Komatsu machinery dealers and repair workshops. We sincerely welcome worldwide partners to place bulk orders and visit our factory to inspect our full-aluminum production and strict quality control workflow.
