Product Details
Product Introduction:
The vertical side‑blowing air curtain (also known as a side‑blowing air barrier) is a box‑type air‑sealing device mounted vertically on one or both sides of a building’s doorway. Powered by a high‑capacity internal fan, it accelerates air and directs it through long, vertical slots on the unit’s sides, projecting a high‑velocity horizontal airflow that forms an invisible, planar air curtain at the entrance. This model is ideal for applications where doorways are excessively tall or where conventional air curtains cannot be installed overhead—such as in shopping malls, factories, warehouses, cold storage facilities, and garages—and it effectively prevents indoor–outdoor air exchange, dust, and flying insects from entering.
Main functions of the Products:
1. Efficient air curtain isolation: A high‑velocity, planar airflow ejected from the side spans the entire width of the doorway, preventing outdoor cold or hot air, dust, exhaust fumes, and insects from entering while maintaining indoor temperature and cleanliness.
2. Energy Conservation and Consumption Reduction: During air-conditioning or heating seasons, energy loss through open doorways is significantly reduced, resulting in energy savings of 30% to 50%.
3. Dust-proof, insect-proof, and odor-resistant: In logistics corridors, food processing areas, and restaurant back entrances, it can prevent flies and insects while blocking the spread of kitchen fumes and external dust.
4. Create a Comfortable Passage: Reduce drafts at entrances of large supermarkets, train stations, and other venues, enhancing comfort in high‑traffic areas.
5. Optional heating and cooling functions: Electric‑heated model: Equipped with a built-in PTC heating element, it delivers a warm air curtain in winter and prevents ice formation around the door. Chilled‑water/hot‑water model: Connected to a central air-conditioning system, it produces a cool air curtain in summer and a warm air curtain in winter.
6. Make-up Air and Ventilation in Large Spaces: The natural ventilation type can be used for auxiliary ventilation and airflow management in areas where air conditioning is not required.

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.
