Product Details

Product Introduction:
Our company manufactures panel-type smoke vents—also known as remotely controlled smoke vents or smoke dampers—which are specialized devices installed in ceilings or walls within building fire‑suppression smoke‑exhaust systems. Normally closed, they are automatically opened upon activation of the fire‑alarm linkage system during a fire to exhaust indoor smoke, thereby facilitating safe evacuation and supporting firefighting and rescue operations. These products are widely used in shopping malls, office buildings, underground parking garages, industrial plants, and other facilities.
General technical parameters (using a mainstream fire‑proof panel‑type smoke vent as an example):

Electric during a fire / Manually activated; normally closed

Applicable Scenarios

Ceiling of rooms, corridors, and smoke-control zones / Wall-mounted smoke exhaust system

Installation method

Recessed ceiling / Wall-mounted, flange‑to‑flange ductwork

   

Applicable Scenarios and Selection Recommendations:
Core use cases:  
1. Indoor smoke exhaust systems for public buildings such as shopping malls, office towers, hotels, and hospitals
2. Mechanical smoke exhaust systems for underground parking garages and equipment rooms
3. Smoke exhaust and ventilation systems for factories and warehouses
Key considerations for selection:
1. Select based on airflow rate and dimensions: Choose diffuser specifications that match the design smoke exhaust volume of each smoke-control zone and the ductwork size, ensuring uniform smoke extraction and minimal pressure loss.
2. Control Mode Compatibility: When interfacing with the fire‑alarm linkage system, it is mandatory to select a model equipped with electric actuation and feedback signals to ensure seamless integration with the fire control room.
3. Installation requirements: Install at the top of a smoke compartment or on a wall near the ceiling, with a horizontal distance from the farthest point not exceeding 30 meters.
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.

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.
