Product Details
Product Overview:
Our company’s GaoDa warm-air heaters are specialized heating units designed for industrial and commercial spaces with ceiling heights of 4 to 30 meters and large spans. Powered by hot water, steam, or electricity as the heat transfer medium, they use high‑velocity jet fans to forcibly deliver warm air, effectively overcoming the common “thermal stratification” phenomenon in tall, open spaces. By efficiently delivering heat to occupied zones, they provide uniform, energy‑efficient heating—making them the preferred heating solution for factories, warehouses, large venues, and similar applications.
Main functions of the Products:
Core Heating and Temperature Equalization ：
High‑velocity jet fans can deliver heated air over long distances, with a delivery range of 15–30 meters, addressing the “hot at the top, cold at the bottom” issue in tall, open spaces. They quickly achieve uniform indoor temperatures and eliminate heating dead zones.
Air Circulation and Heat Recovery ：
It promotes continuous air circulation indoors, prevents cold air from settling, and recovers heat from the warm air at the ceiling, thereby reducing heat loss through the building envelope. Compared with conventional heating systems, it achieves energy savings of 20% to 40%.
Heating adapted to multiple scenarios:
1. Suitable for industrial plants, machining workshops, automotive manufacturing facilities, and other production environments;
2. Suitable for winter insulation in e‑commerce fulfillment centers, logistics warehouses, large supermarkets, and sports arenas;
3. Some models that support both cooling and heating feature a summer‑mode air‑delivery/cooling coil, enabling dual functionality in a single unit.
Intelligent Control and Energy-Efficient Operation:
Standard equipped with a thermostat, supporting automatic temperature adjustment and timed on/off operation; some models also offer app-based remote control and multi-unit linked zone‑based temperature management, with variable airflow regulation to meet site-specific needs and reduce energy consumption.
Special Environment Adaptation ：
Customizable explosion-proof and corrosion-resistant models are available, suitable for chemical plants and other specialized industrial environments where flammable or explosive gases are present. High-temperature and low-temperature‑resistant models can meet the demands of extreme operating conditions.

Note: For steam‑type models, the heating capacity increases as steam pressure rises (0.2–0.6 MPa); for electric‑heating models, the power typically ranges from 10 to 60 kW, with specific specifications varying slightly by brand and model.
Additional Notes and Key Selection Considerations:
Heat Transfer Fluid and Model Selection:
1. In scenarios with a centralized hot water or steam heat source, prioritize the hot water or steam‑type model, as it offers lower operating costs.
2. In scenarios without a centralized heat source, an electric heating model can be selected, offering convenient installation and flexible control.
3. For spaces with a ceiling height exceeding 20 meters, it is recommended to select an extra-large model with a supply air distance of ≥25 meters to eliminate heating dead zones.
Key selection criteria:
The required heating capacity must be calculated based on the building’s floor-to-ceiling height, insulation conditions, and target indoor temperature (for every 3 meters of ceiling height exceeding this, an additional 5%–10% of load should be accounted for); meanwhile, select a model with an appropriate supply‑air distance according to the building’s span.
Installation and Usage Precautions:
1. The recommended lifting height is 4–6 meters above the ground to avoid direct airflow onto areas where personnel are active.
2. Hot-water and steam‑type units require regular inspection of piping and coil tubing to prevent scale buildup that could impair heat‑transfer efficiency.
3. In flammable and explosive environments, explosion-proof units must be used, along with explosion-proof fans and control components.

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.
