Resolving Radiator Failures in Mining Dozers with SINRUI's Copper Core Solution

At a mining site in Indonesia, dozens of bulldozers (including D8R, D9R, D10 and D11 models) are waiting for inspection and repair due to failure.

️ The Problem: Premature Failure of OEM Radiator Components

During a survey of Indonesian mines, it was discovered that the OEM radiator systems used on dozens of large mining bulldozers were failing just two months after installation.

The rubber mounting components had deteriorated rapidly, showing signs of cracking and wear.And the modular radiator cores AMOCS exhibited serious corrosion, with visible aging, reduced structural integrity, and performance degradation.

Multiple bulldozers had to be taken offline, waiting for radiator repairs, causing interruptions in daily operations.

High Downtime, High Cost

️ Every two months, the entire cooling unit must be disassembled and transported over long distances for repair — a process that’s time-consuming and costly.

✅ The Sinrui Solution: Replace AMOCS with Copper Fin Tube Modules

To address the frequent failures and short service life of mining cooling systems, Sinrui offers a custom cooling solution using:

Heavy-duty remaovable copper fin tube cores and component kits, designed to fit with mining bulldozers like the D8R, D9R, D10, and D11.

Why Copper-Based Cooling Works Better for Mining:

SINRUI’s copper tube and fin radiator systems are specifically engineered for the harsh conditions found in mining operations. Here’s why they deliver superior performance and reliability:

·  Excellent Corrosion Resistance
Copper naturally resists corrosion, especially in humid, acidic, or dust-heavy environments common to open-pit mines. This ensures longer service life and fewer failures.

· Strong Structural Durability
Copper cores offer high mechanical strength, making them resistant to vibration, impact, and thermal fatigue — all of which are typical in heavy-duty mining equipment.

· Easy Maintenance and Cleaning
Copper fin structures can be safely cleaned using high-pressure water jets without damaging the core, reducing the time and labor required for maintenance.

·  Modular and Repairable Design
SINRUI radiators are built with a replaceable copper core and detachable parts. When one section wears out, it can be swapped without replacing the entire unit.

·  Extended Service Life
With proper use and routine maintenance, SINRUI copper-core radiators can operate reliably for more than 4 years — far exceeding the typical lifespan of standard systems.

·  High Thermal Efficiency
Copper’s superior thermal conductivity ensures faster and more stable heat dissipation, which helps protect engines from overheating, even under full load.

·  Backed by a 4-Year Warranty
Our confidence in the product’s performance is reflected in our long-term warranty, offering peace of mind and lower total cost of ownership.

Designed for Harsh Environments

Mining sites in Indonesia—and similar regions—face extreme dust, vibration, and temperature fluctuations. That's why Sinrui cooling systems are built for:

✔️ Longer operating cycles

✔️ Rapid on-site cleaning and maintenance

✔️ Reduced risk of corrosion or seal failure

✔️ Better thermal efficiency over time

OEM ≠ Always Optimal

The fact is, OEM doesn’t always mean optimal. Our products are engineered to handle tough mining environments with fewer failures and reduced maintenance cycles.

Sinrui radiators are engineered with mining environments in mind — not just for performance, but for long-term value.

If you’re facing frequent radiator issues, rising maintenance costs, or downtime delays — talk to our engineering team.

We’ll help you customize a cooling solution that lasts longer and saves more.
