Mini Excavator
Cooling Systems
Compact cooling solutions for mini and compact excavators. Engineered for urban jobsites with tight space constraints and low noise requirements.
Compact Cooling Needs
Mini excavators require highly integrated cooling solutions due to extremely limited engine compartment space. Many units require compact 2-in-1 packages combining engine cooling and hydraulic oil cooling.
Engine Coolant
Compact radiator for small diesel engine. 15-40 kW typical.
Hydraulic Oil
Combined pump and cylinder heat rejection.
Charge Air (if equipped)
Stage V compliant units require CAC cooling.
Compact Integration
- 2-in-1 radiator/oil cooler packages
- Optimized for small engine bays
- Low noise fan configurations
- Cost-effective solutions
Mini Excavator Constraints
Ultra-Compact Packaging
Very limited space in engine compartment requires highly integrated cooling solutions.
Zero Tail Swing
Many mini excavators have zero or reduced tail swing, further limiting cooling package placement.
Low Noise Requirements
Urban jobsites have strict noise regulations requiring quiet cooling fan operation.
Rubber Track Vibration
Rubber track systems create different vibration characteristics than steel tracks.
Simple Maintenance
Operators expect easy access for basic maintenance and cleaning.
Cost Sensitivity
Compact equipment market is highly price-competitive.
