Product Details
Product Introduction:
Our company manufactures stainless steel round dampers—specialized flow‑control valves designed for circular ductwork. These dampers are widely used in ventilation and air-conditioning systems, exhaust‑gas treatment, chemical processing, food and pharmaceutical industries, and other sectors, enabling precise airflow regulation, duct opening and closing, and system balancing. With outstanding corrosion resistance, hygienic properties, and high‑temperature tolerance, they are the preferred choice for demanding applications involving humid, corrosive environments or stringent hygiene requirements.
General technical specifications (using a mainstream 304 stainless steel round manual damper as an example):

Applicable Scenarios and Selection Recommendations:
Core use cases:
1. Airflow regulation for anti-corrosion exhaust ducts in the chemical and electroplating industries
2. Ventilation and exhaust systems for food processing plants and pharmaceutical manufacturing facilities
3. Airflow control for kitchen exhaust and steam piping (high-temperature resistant model)
4. For ventilation ducts in humid environments and underground spaces, prevent valve corrosion.
5. Fresh-air purification system and airflow balance in cleanrooms
Key considerations for selection:
1. Select based on duct diameter: Prioritize models that precisely match the duct’s inner diameter to avoid installing reducers, ensuring smooth airflow and minimal pressure loss.
2. Select material based on operating conditions: For ordinary humid environments, choose 304 stainless steel; for highly corrosive environments involving strong acids or strong alkalis, select 316L stainless steel.
3. Selection based on control method: Choose the manual version if only on-site adjustment is required; upgrade to an electric actuator when remote control or integration with an automation system is needed.
4. Sealing and High-Temperature Resistance Requirements: When stringent pipeline sealing is required or the medium temperature is relatively high, it is recommended to select high-temperature‑resistant sealing strips.

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.
