Typical Thermal Circuits
Construction machinery cooling systems typically manage multiple thermal circuits, each with specific temperature targets and flow requirements.
Engine Coolant Circuit
Primary engine heat rejection via radiator. Temperature target: 85-95°C
Charge Air Circuit
Turbocharger outlet air cooling for emissions compliance. Pressure: up to 4.5 bar
Hydraulic Oil Circuit
Pump, motor, and valve heat rejection. Temperature target: 60-80°C
Transmission / Lube Oil
Gearbox and drivetrain cooling. Continuous duty rated.
Construction-Specific Constraints
Limited ram air; cooling fan is primary air source
Fin spacing and core access critical for cleanability
Track-induced loads require fatigue-rated designs
Multi-circuit packs optimize packaging efficiency
Stage V / Tier 4 Final thermal management requirements
Maintenance in remote locations with limited tools
Key Challenges & How We Solve Them
Dust Fouling
Debris accumulation reduces heat transfer and causes overheating
Wide fin spacing, easy-clean core designs, serviceability access
Vibration Fatigue
Track and engine vibration causes structural failures
Reinforced headers, fatigue-tested mounts, validated duty cycles
Packaging Constraints
Limited space with multiple heat rejection requirements
Modular multi-circuit packs, optimized core sizing, custom tanks
High Ambient & Altitude
Operation in extreme temperatures and reduced air density
Enhanced surface area, optimized fin density, altitude compensation
Maintenance Access
Field service in remote locations with limited tools
Bolt-on designs, accessible fittings, replaceable modules
Emissions Compliance
Stage V / Tier 4 Final require precise thermal management
Charge air cooler optimization, EGR cooling, thermal modeling
