Product Details
Product Overview:
Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used for cooling and dehumidifying air, and can also be switched to hot-water or steam mode during winter to provide air heating.
It achieves forced convection heat exchange between the refrigerant (such as chilled water, refrigerant, or brine) or heat transfer fluid (such as hot water or steam) flowing inside the tubes and the air flowing outside, thereby regulating the air’s temperature and humidity. As a core heat-exchange component in central air-conditioning units, fresh-air handling units, fan coil units, and similar equipment, it combines high heat-transfer efficiency with flexible installation and strong adaptability.

Note: Model designations typically incorporate dimensions, number of rows, and airflow rate; for example, “TL-2000-4R” denotes a surface cooler with an airflow of 2,000 m³/h and four rows of tubes. Fin materials can be selected from hydrophilic aluminum foil or corrosion‑resistant aluminum foil, making it suitable for humid or corrosive operating conditions.
Scope of Product Use:
Air coolers are widely used in various applications that require air temperature and humidity control, primarily including:
HVAC field:
The core heat-exchange components of central air-conditioning units, packaged air-handling units, fan coil units, and fresh-air air-conditioning units are used to cool, dehumidify, and heat the air in shopping malls, office buildings, hotels, and residential spaces, thereby achieving indoor temperature and humidity control.
Industrial Ventilation and Process Air Conditioning:
In facilities such as electronics manufacturing plants, pharmaceutical workshops, food-processing facilities, and textile mills—where stringent requirements for air cleanliness, temperature, and humidity prevail—this system is employed for cooling and dehumidification in process air‑supply systems, ensuring a stable production environment.
Special Operating Conditions Applications:
In cold storage and low-temperature preservation facilities, the pre-cooling system employs low-temperature surface coolers using brine or ethylene glycol as the refrigerant. In high-temperature drying systems, the surface cooler can be switched to operate with hot water or steam, thereby providing air heating.
Energy Conservation and Waste Heat Recovery Scenarios:
When combined with heat pump systems and waste‑heat recovery systems, it recovers the cooling or heating energy from exhaust air, thereby reducing air‑conditioning energy consumption; it can also serve as auxiliary heat‑exchanging equipment for cooling towers and evaporative condensers.

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.
