Key Features
Core Advantages: Engineered for the Most Challenging Environments
1. Durable Materials for Longevity
- Structure: Expertly crafted with robust 304 stainless steel or resilient Q235 carbon steel frames, these products are surface-treated with advanced hot-dip galvanization or premium powder coating. This meticulous engineering ensures remarkable resistance to high humidity, corrosive acidic gases such as ammonia often found in livestock barns, and dust, thereby extending the product's service life by an impressive margin of over 50%.
- Protection Rating: Rated at IP55 for superior dustproof and waterproof capabilities, this design guarantees impeccable performance in outdoor or damp environments, requiring minimal maintenance for prolonged efficiency and peace of mind.
2. Powerful Ventilation & Temperature Control
- High Airflow Design: Fitted with low-speed, high-torque pure copper motors and large impellers ranging between 300mm to 1200mm, this system delivers an impressive air volume of up to 15,000 m³/h. This capability ensures swift expulsion of hot and humid air, unpleasant odors, and hazardous gases, effectively reducing temperature and humidity in greenhouses and livestock facilities. The result is a significant decrease in mold growth and stress levels in animals, fostering healthier environments.
- Quiet Operation: With aerodynamically optimized impellers, this technology maintains noise levels at or below an unobtrusive 75dB, ensuring a serene atmosphere that minimally disturbs livestock and promotes optimal crop growth.
3. Flexible Installation & Adaptability
- Compact Square Design: Ingeniously designed to mount flush against walls, this space-saving feature is ideal for greenhouse side walls, livestock barn walls, or ceilings, with the option of ceiling brackets, providing versatility in installation.
- Adjustable Airflow Angle: The manual adjustment capability of the blade angle, from 0 to 45°, allows precise direction of airflow, making it perfect for targeted ventilation. Whether it is bottom ventilation for seedbeds or cooling for lively livestock activity areas, this feature enhances user control and customization.
4. Intelligent Control & Energy Efficiency
- Multi-Speed Settings: Offering a 3-speed control system (high/medium/low), this feature caters to varying seasonal and environmental demands, optimizing energy use, and significantly reducing consumption without compromising performance.
- System Compatibility: Seamlessly connects with temperature and humidity sensors or advanced PLC control systems. This integration allows for automatic start/stop functions and speed adjustments, empowering users with smart environmental management and enhanced operational efficiency.
