Direct Gas-Fired Industrial Air Heater WEDONE

High-volume process air heating with fast response, efficient fuel use and low-emission options.

The WEDONE Direct Gas-Fired Air Heater produces high-volume heated air for industrial process applications. Fuel is burned directly within the airflow, allowing rapid temperature response and efficient transfer of combustion heat to the process air.

WEDONE provides duct-style and gun-style configurations to suit different airflow arrangements, installation spaces and process requirements.

• Direct-fired design for efficient process-air heating
• Rapid response to changing temperature requirements
• Suitable for high-volume airflow applications
• Duct-style and gun-style configurations available
• Fuel, airflow and temperature capacity customized for each project
• Automatic burner and temperature controls
• Safety interlocks for ignition and operating protection
• Low-emission configurations available
• Compact structure simplifies integration with process ductwork

    Core advantages 

    As their name suggests, direct-fired air heaters apply heat directly to the product air stream. These heaters are used when a hot air source is needed for applications that are not sensitive to the by-products of combustion: drying, heat treating, sand or clay processing, printing, or coating, cement production, composite curing, fertilizer production, etc. Regardless of the application, we have a direct-fired air heater to fit your process needs.

    Frequently Asked Questions

    1
    How does a direct gas-fired air heater work?
    The burner releases combustion heat directly into the process airflow. Because there is no separate heat exchanger between the flame and the air, the system can provide rapid heating and efficient heat transfer.
    2
    What is the difference between the duct-style and gun-style models?
    A duct-style heater is integrated into the process-air duct, while a gun-style unit projects the burner assembly into a chamber or airflow section. The appropriate design depends on the duct dimensions, airflow pattern, installation space and required temperature rise.
    3
    Which fuels can the air heater use?
    The system is primarily designed for gaseous fuels such as natural gas or LPG. Other fuel options may be evaluated according to the project, burner configuration and available fuel supply.
    4
    Can the outlet-air temperature be controlled automatically?
    Yes. Temperature sensors and automatic burner controls regulate the heat input according to the required outlet temperature. The control system can also be integrated with the customer’s production equipment.
    5
    What information is required to select an air heater?
    Please provide the airflow volume, inlet and required outlet temperatures, available fuel and pressure, duct dimensions, process application, operating schedule, site conditions and applicable emission requirements.
