Centac Air Cooler

Technical Features: Data-Driven Industrial Design

1. Compact Structure and Heat Exchange Efficiency

The Centac Air Cooler features dual-mode design with aluminum alloy plate-fin (air-cooled) and shell-and-tube (water-cooled) configurations, achieving a heat transfer coefficient of 230-815W/(m²·℃). The C400 model, for example, utilizes a vertically split casing integrated with intercoolers and condensate drainage systems on a single chassis, reducing footprint by 30% and installation costs by 45%. Its ternary flow design with backward-curved impeller blades creates straight-through airflow channels, decreasing pressure loss by 18% while maintaining noise levels below 82dB (compliant with ISO 3744 standards) - significantly outperforming traditional centrifugal compressors.

2. Materials and Manufacturing

The cooler's heat transfer tubes employ copper tubes with rolled fins, precisely manufactured to 0.8mm wall thickness and 2.5mm fin spacing, ensuring structural stability at temperatures up to 120℃. Heat exchange areas adapt dynamically to flow requirements:

Unit Size	Flow Capacity	Heat Exchange Area	Pressure Range
Small	≤100m³/min	≥15m²	0.8-1.6MPa
Medium	100-500m³/min	30-60m²	2.5-4.0MPa
Large	＞500m³/min	＞80m²	Special requirements

3. Intelligent Control System

The Centac Air Cooler features CMC intelligent controller with:

• Constant pressure control: PID algorithm maintains ±0.01MPa pressure fluctuation, reducing energy consumption by 22% compared to traditional two-step control
• Self-diagnostics: 128 sensors monitor bearing temperature (±1℃ accuracy), vibration (0.1-100Hz range), oil pressure (0.1-1.0MPa) with 72-hour failure prediction
• Remote monitoring: Modbus TCP/IP protocol enables integration with plant DCS systems for optimized multi-unit operation

4. Energy Saving & Environmental Protection

• Three-stage compression reduces exhaust temperature by 15℃ and energy use by 30%
• Oil-free certification meets ISO 8573-1 Class 0 standards through graphite ring seals and independent lubrication
• Waste heat recovery improves total efficiency by 12-18% for process heating or facility warming
