Large Excavator
Cooling Systems
High-capacity cooling for mining and quarry class excavators. Engineered for maximum heat rejection, severe vibration, and demanding operating environments.
High-Capacity Systems
Large excavators in mining and heavy earthmoving applications require cooling systems capable of rejecting 250-500+ kW of heat. These platforms often feature multiple independent cooling circuits and modular designs for serviceability.
Engine Coolant
High-capacity radiator for large diesel. 120-200+ kW.
Charge Air
Large CAC for twin-turbo or high-output engines.
Hydraulic Oil
High-flow hydraulic systems for heavy digging.
Transmission / PTO
Track drive and power take-off cooling.
Mining-Grade Design
- Extra-heavy construction for durability
- Modular design for field service
- Wide fin spacing for mining dust
- Extreme vibration validation
Large Excavator Constraints
Maximum Cooling Capacity
Large excavators require substantial heat rejection capacity, often exceeding 300 kW total.
Severe Vibration
Heavy track frames and high-power digging create extreme vibration loads on cooling systems.
Mining Environment
Operation in mining conditions requires enhanced dust management and corrosion protection.
Extended Service Life
High-value assets require cooling systems designed for long service life and reliability.
Field Serviceability
Remote mining locations demand easy maintenance and component replacement capability.
Multiple Engine Options
Large excavators may have multiple engine variants requiring adaptable cooling solutions.
