1. Product Overview: Core Temperature Control module for Centrifugal Compressor system setups

The Centac Cooler 2CV is a specialized cooling unit designed by AirsCooler for CENTAC series centrifugal air compressors, serving as a critical heat exchange module in multi-stage compressed air system setups. 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 overall efficiency Optimization: minimizes energy consumption in subsequent processes by lowering air temperature, improving mold filling overall efficiency by over 15% in PET blow molding use cases
• system setup 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 keep 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-overall efficiency Sleeve Air Cooler (Patented Technology)
  • Heat transfer overall 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 loss ≤0.02 bar, keep system setup COP >3.5
  • Corrosion resistance: Copper tubes with Heresite coating withstand 100ppm sulfur environments for 10+ year service life
