Key Features
Core Advantages: Built for Tough Conditions
1. Durable Materials for Longevity
- Structure: Our air cooler boasts a robust build, featuring frames crafted from either 304 stainless steel or Q235 carbon steel. These frames undergo surface treatments like hot-dip galvanization or powder coating, providing exceptional resistance against high humidity, acidic gases (including ammonia in livestock barns), and dust. This meticulous construction extends the service life by more than 50%.
- Protection Rating: Rated at IP55, our air cooler offers superior dustproof and waterproof capabilities, ensuring it operates efficiently in outdoor or damp environments with minimal maintenance required over time.
2. Powerful Ventilation & Temperature Control
- High Airflow Design: Equipped with high-performance low-speed, high-torque pure copper motors, our air cooler features impellers ranging between 300mm and 1200mm in diameter. This design delivers an impressive airflow of up to 15,000 m³/h, efficiently expelling hot, humid air, odors, and harmful gases. This leads to reduced temperature and humidity levels in greenhouses and livestock facilities, significantly minimizing mold growth and reducing animal stress.
- Quiet Operation: Our aerodynamically optimized impellers ensure noise levels remain at or below 75dB, preventing disturbances to livestock or crop growth, thereby creating a serene environment.
3. Flexible Installation & Adaptability
- Compact Square Design: The sleek square design of the air cooler allows it to be mounted flush against walls, maximizing space efficiency. It is perfectly suited for installation on greenhouse side walls, livestock barn walls, or ceilings, with optional ceiling brackets available.
- Adjustable Airflow Angle: With manual blade angle adjustments from 0° to 45°, our air cooler offers precise airflow direction, perfect for targeted ventilation scenarios such as bottom ventilation for seedbeds or localized cooling in livestock activity areas.
4. Intelligent Control & Energy Efficiency
- Multi-Speed Settings: Our air cooler features a versatile 3-speed control system, accommodating high, medium, and low settings to adapt to seasonal and environmental changes. This flexibility aids in reducing energy consumption while maintaining optimal performance.
- System Compatibility: Seamlessly integrates with temperature and humidity sensors or PLC control systems, allowing for automatic start/stop functions and speed adjustments. This connectivity facilitates intelligent environmental management, ensuring a consistently comfortable and efficient climate.
