Charge Air Cooler
The charge air cooler (CAC) reduces the temperature of compressed air from the turbocharger before it enters the engine, increasing air density and improving combustion efficiency. Optimized fins and tubes ensure high heat transfer performance, while durable, simplified construction supports long-term reliability.
The Air-Cooled CAC efficiently transfers heat from high-temperature, high-pressure charged air to ambient air.
The Water-Cooled CAC transfers heat from the high-temperature, high-pressure charge air to coolant. Typically, WCACs operate in conjunction with air-cooled low temperature radiators.
