Why MineCool Cooling Components outperforms OEM parts for Caterpillar 793F Mining Trucks

The cooling challenges of the Caterpillar 793F Mining Truck

Original Equipment Manufacturer (OEM) parts have long been the standard for maintaining heavy mobile mining equipment like the Caterpillar 793F Mining Truck.

But with growing pressure on performance, part availability and pricing, MineCool is the leading OEM cooling component alternative when it comes to Australian mining.

MineCool is a world-class cooling components engineering specialist offering direct-fit aftermarket parts engineered to meet—and often exceed—OEM standards. Designed and engineered in Australia and for Australia’s toughest mining conditions, MineCool products deliver proven reliability you can trust.

One of these extreme duty solutions is the MC60023AC Charge Air Cooler (CAC). Built with reinforced heavy-duty manifolds and high-performance cores, it is designed to suit all versions and serial numbers of 793F mining trucks.

OEM issue: premature cracking in the CAT 370-9333 CAC

Premature cracking has been identified in OEM CAT 370-9333 Charge Air Cooler (CAC) cores, most commonly occurring around the inlet side where components are exposed to the highest levels of heat, vibration and pressure.

Over time, these stresses can lead to structural fatigue, reduced cooling efficiency, and an increased risk of unplanned downtime for Caterpillar 793F fleets operating in demanding conditions.

MineCool engineering solution: re-designed 793F Charge Air Cooler (MC60023AC)

Rather than replicate this product, MineCool engineered a redesigned 793F CAC to address this cracking. The result includes:

• Reinforced Manifolds
  Upgraded with thicker walls to increase durability, improve heat transfer and withstand harsh operating conditions.
• Optimised Internal Design
  Strategically positioned splitters and baffles within the tanks enhance structural integrity.

Together, these MineCool CAC product enhancements create:

• Significantly stronger manifolds – reducing the risk of cracking, a common issue with standard OEM CAC models.
• Improved airflow and heat transfer.
• Greater reliability and better durability under extreme heat cycling and pressure.

Here is how the air flows through the CAC with greater balance and consistency, cooling the 793F as expected.

CASE STUDY: How MineCool solved OEM cracking failures

When premature cracking was identified on OEM CAC cores (CAT 370-9333), around the inlet side where heat and vibration are highest, the MineCool engineering team set out to redesign the component from the ground up to provide a quality alternative to the OEM product.

MineCool re-engineered the Caterpillar 793F CAC to better direct and control airflow, ensuring uniform distribution and improved heat transfer for greater durability and performance under extreme operating conditions.

The result is a strengthened, longer-lasting solution that reliably withstands heat cycling and pressure—outperforming the original OEM design and keeping Caterpillar 793F fleets performing with  MineCool.
