Centac Cooler 5C

1. Product Overview: Core Component for Efficient Heat Exchange

The Centac Cooler 5C serves as the critical temperature control component in industrial centrifugal air compressor systems. Engineered based on multi-stage compression thermodynamics, it enhances heat transfer efficiency between air and cooling media to ensure stable compressor operation under high-efficiency conditions. This modular cooler integrates with Centac series compressors' three-stage compression units, working alongside diffusers and sealing systems to form a complete thermal management solution.

1.1 Structural Composition and Operating Principle

The cooler features a multi-tube flow path system with copper tube/stainless steel cover composite construction. Air flows through tubes while cooling water circulates externally, creating counter-flow heat exchange channels. Wave-shaped fins increase air-side heat transfer area by 30+%. Water distributes evenly via top headers while air enters from the bottom, forming spiral upward flow guided by diffusers for optimal turbulent contact. This design reduces air temperature from 150-180°C post-compression to 40-50°C with 75%+ cooling efficiency.
