Centac Cooler C160

Product Overview: Core Component for Industrial Cooling

The Centac Cooler C160 is a high-efficiency heat exchange device specifically designed for industrial-grade air compressor systems. As a critical component in post-compression processing, its primary function is to reduce the temperature of hot oil-gas mixtures (generated during compression) below 80°C using cooling media (water or air), preventing lubricant breakdown, bearing wear, and system efficiency degradation caused by excessive heat. Featuring modular design, it supports both air-cooled (AC type) and water-cooled (WC type) configurations to meet diverse operational requirements.

1.1 Technical Positioning & Market Value

As a complementary component for Centac series compressors, the C160 cooler serves as the "thermal gatekeeper" in compressed air systems. Its technical parameters directly impact the compressor's Energy Efficiency Ratio (EER) and maintenance costs. In an automotive manufacturing case study, implementing the C160 water-cooled solution achieved annual electricity savings of 120,000 kWh per compressor while maintaining compressed air quality (dew point) within 2-10°C, significantly reducing defect rates in paint shops.

1.2 Structural Features & Material Advantages

• Dual-Media Compatibility: Water-cooled version features 316L stainless steel heat exchange tubes with 1.5mm wall thickness, withstands ≤0.4MPa water pressure; air-cooled version has aluminum fin arrays with 12.5m² surface area and optimized 2.8mm fin spacing to minimize dust accumulation.
• Smart Control System: Integrated temperature sensors and pressure compensation valves automatically trigger alarms and activate backup cooling circuits when inlet water temperature exceeds 32°C or pressure fluctuations surpass ±0.05MPa.
• Sealing Protection: Critical joints utilize O-ring + metal gasket dual sealing, passing 10bar pressure tests to prevent downtime from coolant leaks.
