Core Product Features
- Jet Structure: The core component is a spherical nozzle assembly, allowing for 360° horizontal rotation and 90° vertical pitch adjustment. This provides concentrated airflow with a long range, reaching over 30 meters.
- Airflow Characteristics: Utilizing a high turbulence coefficient design, it delivers fast airflow and slow temperature decay, enabling rapid temperature equalization in large spaces.
- Control Methods: Supports manual adjustment and electric actuator control. It can be integrated into building automation systems for remote directional airflow and volume adjustment.
Applicable Scenarios
- Typical Scenarios: Large-space buildings (gymnasiums, airport terminals, high-speed rail station waiting halls, large factories, exhibition centers).
- Special Scenarios: Locations requiring targeted airflow (e.g., stages, exhibition halls, logistics warehouses), or large spaces requiring downward heating in winter.
Core Value
- High-Efficiency Airflow: Long-distance jet capability covers large areas, reducing the number of air vents and lowering system costs.
- Precise Control: 360° adjustable angle enables targeted airflow, meeting the personalized temperature needs of different areas.
- High Adaptability: Capable of adapting to harsh environments such as high temperature, high humidity, and high dust levels, making it an ideal choice for industrial and large public buildings.
