Charge Air Coolers (CAC)

Overview

XinSheng Charge Air Coolers (CACs) are precision-engineered heat exchangers that cool compressed intake air from turbochargers and superchargers. By reducing intake air temperature, our CACs enable higher power density, improved fuel efficiency, and reduced emissions for diesel and gas engines across harsh-duty applications.

Technology

Our CACs utilize two primary construction technologies:

Bar & Plate Design

• Robust construction for high-pressure applications
• Superior durability in high-vibration environments
• Easily serviceable and cleanable
• Ideal for mining, construction, and heavy-duty applications

Tube & Fin Design

• Lightweight with excellent heat transfer
• Cost-effective for high-volume applications
• Optimized airflow characteristics
• Suitable for agricultural and mobile equipment
