Product Details
Product Introduction:
The centrifugal air curtain is a high-performance air-sealing device specifically designed for tall, spacious lobbies, industrial plants, cold storage facilities, warehouses, and the main entrances of large shopping malls. Compared with conventional cross-flow (horizontal‑flow) air curtains, it employs a forward‑curved, multi‑blade, dual‑inlet centrifugal fan, offering superior advantages such as high static pressure, long airflow reach, and high outlet air velocity. It can create a dense, continuous air barrier across doorways exceeding 4 meters—or even 6 meters—in height, effectively preventing indoor–outdoor air convection while blocking the ingress of dust, insects, and odors, thereby delivering substantial energy savings and maintaining a clean indoor environment.
Main functions of the Products:
1. Strong thermal break and energy efficiency: Thanks to the high‑velocity, high‑pressure airflow generated by centrifugal fans, the air curtain can fully cover even tall doorways. Even under significant wind pressure differentials, it maintains a stable air barrier, reducing heat and cooling losses by 40% to 60% and significantly lowering heating and cooling energy consumption.
2. Dust-proof, insect-proof, and odor-proof: It creates a high‑speed isolation barrier that effectively prevents outdoor dust, exhaust fumes, flying insects, and indoor odors and cooking fumes from spreading into the interior, making it particularly well suited for entrances to food processing facilities, pharmaceutical warehouses, and clean corridors.
3. Temperature Buffering and Comfort: Electrically heated or hot‑and‑cold water‑powered centrifugal air curtains can deliver warm or cool air at the entrance, blocking cold drafts in winter and heat waves in summer, thereby enhancing comfort for people entering and exiting and eliminating discomfort for both customers and employees.
4. Auxiliary Airflow Circulation: The natural‑air mode can be activated independently during non‑air‑conditioned seasons to circulate indoor air in large spaces, enhancing ventilation.
5. Durable and wind-pressure resistant: Centrifugal fans feature a robust design, making them well-suited for long-term, stable operation in applications with significant internal–external pressure differentials—such as the ground floors of high-rise buildings or areas exposed to strong winds—or at large doors that are frequently opened and closed.

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.
