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.

Cooling coil

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.

Fresh air ventilator

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.

Q-type steam heater

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.

Cassette fan coil unit

A cassette fan coil unit is an air-conditioning terminal device installed within the ceiling of a room, with only the decorative supply air grille exposed on the ceiling surface. It typically features four‑ or three‑way airflow, with centralized return air at the center; the airflow is delivered in a radiant pattern that closely follows the ceiling, ensuring uniform indoor temperature distribution with no dead zones. It is widely used in settings where aesthetic appeal and comfort are paramount, such as hotel lobbies, office spaces, brand‑name retail stores, private dining rooms, and high‑end residences. The unit comes equipped with a built‑in condensate lift pump, allowing flexible adaptation to varying drainage conditions, and can be conveniently operated via wireless remote control or an LCD wired controller.

Modular air conditioning unit

A packaged air-conditioning unit is composed of various modular air-handling components that can be flexibly configured from different functional sections according to specific application scenarios and treatment requirements, enabling comprehensive, all‑round air conditioning to meet the demands of diverse environments for temperature, humidity, cleanliness, and fresh‑air supply.

Electrostatic precipitator

Our company manufactures duct‑type micro‑electrostatic dust collectors—also known as duct‑mounted electronic air purifiers—which are plug‑in or section‑type air purification devices specifically designed for central air conditioning and fresh‑air systems. By utilizing a high‑voltage electrostatic field, these units charge airborne particulates, which are then captured by collection plates, achieving highly efficient removal of PM2.5, dust, pollen, bacteria, and other pollutants. This equipment features low airflow resistance, high purification efficiency, and no need for secondary consumable replacements (the collection plates can be cleaned and reused), effectively improving indoor air quality while reducing dust buildup in ductwork and extending the maintenance intervals of air‑conditioning systems. It is widely used in ventilation systems across various commercial and public buildings.

Oil fume purifier

Our company manufactures fume purifiers—devices that use mechanical means to filter harmful gases and particulate matter from indoor air before discharging it outdoors, thereby meeting environmental standards. These purifiers are primarily used in hotels, restaurants, eateries, food-processing facilities, and urban environmental protection initiatives, helping to reduce pollutant emissions, improve air quality, and mitigate noise pollution.
