Centac Cooler Ch5

1. Product Overview: Core Cooling Unit for Industrial Compressed Air Systems

The Centac Cooler CH5 by Fete Vessel is a specialized cooling unit designed for medium and small centrifugal air compressors, serving as a critical component in the Centac compressor series. This compact modular cooler combines air cooling with system integration technology to address efficiency loss, increased energy consumption, and reduced equipment lifespan caused by high temperatures during compressed air production.

1.1 Core Functional Positioning

As a key subsystem for Centac centrifugal air compressors, the CH5 cooler performs these essential functions:

• Interstage Cooling: Reduces compressed air temperature between compression stages to decrease subsequent compression work and improve overall efficiency
• Aftercooling: Cools final discharge air to meet process temperature requirements for downstream equipment
• System Protection: Prevents bearing lubrication failure, seal aging, and electrical component faults caused by overheating

1.2 Technical Evolution Background

With Industry 4.0 demanding higher efficiency from compressed air systems, traditional coolers have shown limitations. The CH5 cooler represents Fete Vessel's optimization based on operational data from over 20,000 Centac units, featuring:

• Material Upgrade: CuNi alloy heat exchange tubes replace traditional copper tubes for better corrosion resistance
• Structural Innovation: Built-in corrugated internal fin tubes increase heat exchange area by 30% while reducing system pressure drop
• Smart Integration: Data communication with CMC (Compressor Microcomputer Control Cabinet) enables remote monitoring

2. Technical Features and Data Specifications: Precision Engineering Meets Efficient Heat Exchange

The CH5 cooler's technical advantages stem from coordinated innovation in materials, structure, and control systems.
