In an open-pit mine in Indonesia, a batch of radiators used in Komatsu 930E trucks has been operating steadily for 6 years.
Despite extreme heat, heavy dust, and continuous vibration, their cooling efficiency remains above 90%.
These radiators were built with SINRUI’s copper fin-tube technology, known for durability and reliability.
Tube quality directly affects cooling performance and radiator lifespan.
SINRUI uses 99.9% high-purity oxygen-free copper from Aurubis, a world-renowned supplier.
This copper meets international standards and is widely used in military and heavy equipment projects.
The fins are made from high-purity copper, offering:
Excellent thermal conductivity (>380 W/m·K)
High corrosion resistance
Great balance between flexibility and strength
This ensures the fins remain evenly spaced, free from collapse or oxidation, even after years of heat and vibration.
These radiators are not generic.
They are engineered for Komatsu 930E platforms and tailored for tough mining conditions in Indonesia.
Design features include:
Tight mechanical bonding between tubes and fins, preventing heat loss
Consistent fin spacing that resists vibration damage
Modular, removable cores for on-site maintenance without full replacement
A 6-year-old unit we tested showed minimal oxidation.
Fin alignment remained uniform, with only an 8–9% drop in cooling efficiency.
SINRUI applies automated tube expansion and precision welding during production.
This guarantees strong bonds between copper tubes and fins.
It also eliminates heat loss caused by uneven spacing or poor manual assembly.
High-temperature solder is used at joints to prevent leaks and ensure structural stability.
Frame parts are protected with corrosion-resistant coatings, further extending lifespan.
Some similar-looking radiators from other brands face:
Uneven fin spacing causing early performance loss
Rust spreading rapidly on untreated copper surfaces
Non-removable designs that increase long-term costs
These issues underscore the value of SINRUI’s high standards in material and design.
A mining radiator isn’t just a component—it’s the heart of a machine’s temperature control.
SINRUI radiators for Komatsu 930 have proven, in real-world mining operations, that performance and longevity are achievable.
Backed by 6 years of field use in Indonesia, SINRUI delivers durable, efficient cooling in the harshest environments.
Because a radiator shouldn’t just “fit”—it should last.
