Concrete Mixer
Cooling Systems
Transit mixers, self-loading mixers, and stationary plants. Cooling systems engineered for continuous drum drive operation and concrete production environments.
Mixer Cooling Requirements
Concrete mixers require cooling systems that handle continuous drum drive operation. The hydraulic system powering drum rotation generates significant heat that must be rejected efficiently.
Engine Coolant
Primary engine cooling for truck or self-propelled chassis.
Drum Drive Hydraulic
Continuous rotation creates sustained hydraulic heat load.
Charge Air (if equipped)
Emissions-compliant engines require CAC cooling.
Self-Loading Mixer Focus
- High hydraulic capacity for loading arm
- Multi-circuit integration
- Compact packaging for visibility
- Corrosion protection
Mixer-Specific Constraints
Drum Drive Heat
Hydraulic or mechanical drum drive generates significant heat during continuous rotation.
Continuous Duty
Drum rotation continues during transit and at jobsite, creating sustained thermal loads.
Concrete Dust
Cement dust and aggregate fines can coat cooling fins.
Water Environment
Wash water and splashing create corrosion concerns.
Urban Operation
Noise and emission requirements in urban delivery environments.
Self-Loader Hydraulics
Self-loading mixers have high hydraulic demands for loading arm and bucket.
