Product Details
Product Introduction:
Our company manufactures spherical diffusers—also known as spherical nozzles—which are specialized air‑handling terminal units designed for high‑ceiling spaces and long‑distance airflow. Their key feature is a built-in, rotatable spherical nozzle that allows the airflow direction to be adjusted freely within a specified angular range. With extended throw distances and substantial airflow volumes, these diffusers deliver targeted ventilation in large areas, making them ideal for applications such as airport terminals, sports arenas, large industrial facilities, and railway stations.

Applicable Scenarios and Selection Recommendations:
Core use cases:
1. Air conditioning supply air for large-scale public buildings such as airport terminals, railway stations, sports stadiums, and exhibition halls.
2. Air supply and ventilation for large industrial buildings, warehouses, and logistics centers
3. Directional air distribution systems for shopping mall atriums, double-height lobbies, theaters, and auditoriums
4. Air supply or localized cooling for high-temperature workstations in industrial plants and workshops
Key considerations for selection:
1. Select the diffuser based on duct size and airflow rate: Prioritize diffuser sizes that match the duct’s internal diameter, and calculate the supply air velocity according to the design airflow volume. It is recommended to keep the air velocity within the range of 3–10 m/s to minimize noise and excessive pressure loss.
2. Select based on adjustment requirements: For applications requiring manual adjustment of airflow direction, choose the manual‑control model; for large‑volume spaces or scenarios that demand seasonal mode switching, we recommend models with electrically adjustable settings, which allow remote control of airflow direction.
3. Select based on installation height: The higher the ceiling, the more you should choose a model with a larger diameter and longer airflow range to ensure that the air reaches the areas where people are active.
4. Material and Appearance Selection: In humid, dust‑prone environments, aluminum alloy is the preferred choice; for applications with high aesthetic requirements, consider powder‑coated finishes that match the color of the ceiling or walls.

Cross-flow air curtain machine
The cross‑flow air curtain employs a large‑diameter, slender cross‑flow impeller—also known as a tangential fan—directly driven by a single‑phase motor to generate a wide, planar, high‑velocity airflow. It is installed above or on the side of doorways. The unit features a flat, rectangular profile with a much reduced depth compared to centrifugal models, allowing it to seamlessly integrate into various ceiling designs. It is particularly well suited for spaces with limited headroom and where aesthetics and quiet operation are paramount, such as shopping malls, supermarkets, restaurants, office buildings, banks, hospitals, and residential garages.
Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used to cool and dehumidify air, and can also be switched to hot-water or steam mode during winter to provide air heating. By utilizing a refrigerant (such as chilled water, refrigerant, or brine) or a heat-transfer medium (such as hot water or steam) flowing inside the tubes, these units facilitate forced‑convection heat exchange with the air flowing outside the tubes, thereby regulating air temperature and humidity. As the central heat-exchange components of chiller units, fresh-air handling units, fan coil units, and other equipment, they offer high heat-exchange efficiency, flexible installation, and broad compatibility.
The ceiling‑mounted fresh air ventilator (ceiling‑type air handling unit) is a central air‑conditioning terminal unit that integrates fresh air exchange, air temperature and humidity control, air filtration and purification, and energy recovery. The unit features a concealed ceiling‑mount installation, suspended within the building’s suspended ceiling. It utilizes chilled water or hot water piping to provide cooling and heating, while simultaneously exhausting indoor stale air and supplying filtered outdoor fresh air. This system not only enhances indoor air quality in enclosed spaces but also regulates air temperature through heat‑exchanger coils, offering both ventilation and central air‑conditioning functions. It delivers energy savings, minimizes floor space occupation, and is widely suited for integration into fresh air systems in commercial, industrial, and large public buildings.
Our company’s Q‑type air heater is an industrial‑grade, forced‑convection heating unit that uses water or steam as the heat transfer medium. It is specifically designed for large‑space applications such as factory and mine workshops, warehouses, large buildings, and drying rooms. The equipment consists of a fan, an electric motor, and a steel finned‑tube radiator integrated into a single unit. Performance tests have demonstrated its stable and reliable operation. By combining “steam heat exchange with forced air supply,” it rapidly heats the air, delivering highly efficient heating and making it one of the mainstream solutions for heating high‑ceiling spaces.
