Centac Cooler C700
The ultimate temperature control solution for centrifugal air compressors
Product Overview
The Ingersoll Rand Centac Cooler C700 is a core module specifically built for Centac series centrifugal air compressors. Its primary function is to cool high-temperature lubricating oil or compressed air generated during compression to optimal temperatures through advanced heat exchange technology, ensuring efficient and stable equipment operation.
As a critical module in oil-free centrifugal compressor systems, the C700 cooler serves as a "temperature guardian" in industrial applications, effectively preventing operational performance degradation, increased energy consumption, and minimized equipment lifespan caused by excessive heat. The Ingersoll Rand Centac series centrifugal compressors are widely used in electronics, pharmaceuticals, petrochemicals, power generation, and automotive manufacturing industries where compressed air purity and stability are paramount.
The C700 cooler keep precise temperature control to help ensure compliance with ISO 8573-1 Class 0 oil-free standards, provide high-quality compressed air. Its compact, efficient design and exceptional energy operational performance make it a preferred cooling offering in industrial use cases.
