Product Details
Product Introduction:
Our company’s fully automatic smoke exhaust and fire‑proof damper is a core component of building smoke control and exhaust systems, integrating smoke removal, fire protection, and automatic control in a single unit. Normally closed, it automatically opens to vent smoke during a fire and, when the temperature of the flue gases reaches 280°C, it closes automatically to prevent the spread of flames. This fully automatic fire‑protection valve combines smoke exhaust functionality with fire‑separation capabilities and is widely used in smoke exhaust ductwork for shopping malls, office buildings, underground parking garages, industrial plants, and other facilities.

Applicable Scenarios and Selection Recommendations:
Core use cases:
1. Ductwork for mechanical smoke-extraction systems in public buildings such as shopping malls, office towers, hotels, and hospitals.
2. Smoke exhaust ducts for underground parking garages, equipment rooms, and tunnels
3. Smoke-exhaust and ventilation ducts for factories and warehouses
4. Smoke exhaust ducts that pass through fire compartments, and smoke exhaust ducts for equipment rooms
Key considerations for selection:
1. Select equipment based on duct size: Prioritize models that match the duct’s inner diameter to avoid installing reducers, ensuring that the exhaust airflow remains unaffected.
2. Control Mode Compatibility: When interfacing with the fire‑alarm linkage system, a fully automatic model equipped with electric actuation and feedback signals must be selected to ensure integration with the fire control room.
3. Installation requirements: Install at locations where smoke exhaust ducts pass through fire compartments and at the entrance to the smoke exhaust fan room, ensuring effective containment of fire spread.
4. Regulatory Compliance: Products must comply with national fire safety standards and possess fire safety certifications to ensure successful fire safety inspection and acceptance.

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.
