Centac Cooler 2CV

1. Product Overview: Core Temperature Control Component for Centrifugal Compressor Systems

The Centac Cooler 2CV is a specialized cooling unit designed by Fete Vessel for CENTAC series centrifugal air compressors, serving as a critical heat exchange component in multi-stage compressed air systems. This cooler efficiently removes heat generated during compression through indirect heat exchange between cooling water and compressed air, ensuring stable operation within flow rates of 720-51,000 m³/h and pressure ranges of 0.7-22.5 kg/cm². Its core functions include:

• Thermal Load Management: Controls outlet temperature below 50°C for high-temperature air (up to 200°C+) from each compression stage, meeting requirements for downstream equipment like dryers and air receivers
• Energy Efficiency Optimization: Reduces energy consumption in subsequent processes by lowering air temperature, improving mold filling efficiency by over 15% in PET blow molding applications
• System Protection: Prevents high-temperature induced seal aging and bearing lubrication failures, extending MTBF (Mean Time Between Failures) beyond 8,000 hours

2. Technical Features and Data Specifications

(1) Structural Innovations and Process Breakthroughs

• Tandem Graphite Seal Floating Ring Technology
  • Dual-seal structure: Inner graphite floating ring maintains 0.05mm clearance with shaft neck, while outer ring uses 12-15 psig clean air as barrier gas, achieving <1% leakage rate with zero oil contamination
  • Temperature resistance: Continuous operation between -40°C to 250°C, suitable for extreme conditions like high-altitude regions (e.g., Qinghai-Tibet Railway)
• High-Efficiency Sleeve Air Cooler (Patented Technology)
  • Heat transfer efficiency: Special internal fin design boosts air-side heat transfer coefficient to 120 W/(m²·K), 40% improvement over conventional smooth-tube designs
  • Pressure loss control: Air-side pressure drop ≤0.02 bar, maintaining system COP >3.5
  • Corrosion resistance: Copper tubes with Heresite coating withstand 100ppm sulfur environments for 10+ year service life
