Product Introduction: SFAAENG-577 All-Aluminum Radiator for CAT 320D93
SFAAENG-577 is a premium full-aluminum radiator tailor-made for CAT 320D93 excavators, a core cooling component built to match the heavy-duty working demands of Caterpillar medium excavators widely used in road construction, mining, municipal engineering and quarry operations. This radiator comes with precise standard dimensions: header size 395×124 and an extra-thick 925×368×100 core, paired with dual Φ58 coolant ports fully consistent with the original machine’s pipeline layout. It delivers powerful continuous heat dissipation to stabilize engine operating temperature, effectively eliminating overheating faults caused by long-hour high-load excavation work.
The most prominent highlight of this model is its full-aluminum integrated construction with exquisite, refined craftsmanship. Unlike hybrid copper-aluminum radiators in the aftermarket, we adopt high-purity aviation-grade aluminum alloy for the entire water chamber, core tubes, cooling fins and side panels. Every structural part is formed by precision stamping and one-piece molding, with neat edges, uniform wall thickness and zero rough burrs. All welding joints are finished with automated seamless brazing technology; the welding lines are smooth, compact and free of tiny gaps or uneven solder buildup, showcasing meticulous workmanship that far surpasses ordinary aftermarket radiators. This sophisticated manufacturing detail fundamentally avoids hidden leakage risks and greatly boosts overall structural tightness.
Our raw material standard exceeds common industry benchmarks, endowing the radiator with outstanding rigidity and vibration resistance. The 100mm thick core adopts reinforced thickened tubes and sturdy dense fins, which will not deform or crack under constant severe jolts and engine vibration from uneven construction sites. Complete full-process anti-rust oxidation treatment is applied to all aluminum surfaces, forming a dense protective film that resists corrosion from mud, mineral dust, rainwater and coastal salt mist. It maintains stable cooling efficiency for years, extending service life significantly and cutting customers’ frequent replacement and maintenance costs.
Strict multi-stage quality control runs through the whole production flow. Each finished SFAAENG-577 radiator undergoes high-pressure air tightness testing, heat dissipation performance simulation and full dimensional inspection before delivery. Supported by our complete mold library, advanced automated production lines and teams of skilled workers with decades of heat exchanger manufacturing experience, we ensure uniform precision and consistent exquisite finish across every production batch.
We provide flexible customized optimization for this CAT radiator upon client demands, such as adjusting fin density or upgrading anti-corrosion coatings for ultra-harsh working environments. Boasting full-aluminum premium materials, delicate manufacturing details, reliable cooling performance and long service life, SFAAENG-577 has become a high-value aftermarket replacement choice for global CAT machinery dealers and repair service providers. We sincerely welcome all partners to place bulk orders and arrange factory visits to witness our all-aluminum production and strict quality inspection workflows.
