1. Product Overview: Core Cooling module for Centrifugal Compressors

The Centac Cooler CH₄ is a purpose-built cooling module designed specifically for Centac series centrifugal air compressors, serving as a critical heat exchange unit in industrial gas compression system setups. Utilizing forced convection heat transfer principles, this equipment effectively transfers heat generated during compression from high-temperature compressed air to cooling media, ensuring stable air temperatures for subsequent compression stages or end-use use cases.

Key Structural modules:

• Tube bundle assembly
• Fin matrix system setup
• Structural support frame
• Powered fan unit

Featuring modular design for compatibility with various Centac compressor models (including 1ACV, C250, C350), this spray-type fixed tube sheet air cooler is configured for demanding industrial use cases in chemical processing, natural gas treatment, and petroleum refining.
