Roller & Compactor
Cooling Systems
Single drum, tandem, and pneumatic rollers. Cooling systems engineered for vibratory loads, continuous operation, and asphalt environments.
Compaction Cooling Needs
Rollers and compactors operate with sustained vibration and continuous duty cycles. The cooling system must handle vibration-induced fatigue while maintaining thermal performance in demanding environments.
Engine Coolant
Continuous duty rated radiator for sustained compaction work.
Hydraulic Oil
Vibrator motors and propel systems generate significant heat.
Charge Air (if equipped)
Emissions-compliant engines require CAC cooling.
Vibration-Rated Design
- Reinforced headers for fatigue resistance
- Flexible mounting provisions
- Validated to vibratory duty cycles
- Brazed construction for durability
Roller-Specific Constraints
Vibratory Loads
Continuous vibration during compaction creates sustained fatigue loads on cooling system components.
Asphalt Environment
Tandem rollers operate near hot asphalt, elevating ambient temperatures and creating vapor exposure.
Continuous Operation
Compaction work proceeds continuously without cool-down periods.
Dust Exposure
Soil compaction generates significant airborne dust affecting heat transfer.
Compact Packaging
Narrow machine widths limit cooling package space.
Operator Comfort
Noise and heat rejection must not affect operator platform.
