The electric hot air generator is a duct heater that can be used for a wide range of applications, including as a heat source for drying ovens, heating furnaces, and various industrial furnaces, as well as in drying processes for painting equipment and food processing. Compared to gas combustion types, it does not contain combustion exhaust gases, allowing for clean hot air usage. It is the same size as conventional gas hot air generators (AH-D series), making it easy to replace during equipment upgrades. It features a unit heater with an over-temperature prevention sensor. Energy savings can be achieved with hot air circulation at a maximum temperature of 250°C. 【Product Specifications】 Heater: Sheath heater Casing: Made of stainless steel (with insulation) Heating target: Air Rated capacity: 116.3 to 465.1 kW (depending on model) Inlet temperature: Ambient temperature to 150°C Outlet temperature: Max. 250°C Design air velocity: 5 to 10 m/s (at 180°C) Power supply: AC200V 50/60Hz 3-phase Installation: Indoor use *For custom manufacturing outside the standard dimensions listed in the catalog, and for customers considering replacement from our gas combustion types (AH-C, AH-D, SAH series), we can accommodate on-site measurements and consultations, so please feel free to contact us.

The "AH-D" is a stainless steel burner that supplies "clean gas hot air" for food heating, paint drying, fiber drying, and hot air curtains. The turn-down ratio is adjustable over a wide range of more than 1:10. Unlike oil burners that require indirect heating, clean gas burners can directly combust within the duct to heat the air, making them efficient. Since it adopts a pre-mixed combustion method, there is no concern about backfire, and it is equipped with an automatic safety combustion device, allowing for safe use. 【Features】 ■ Wide adjustment range ■ High reliability ■ Efficient heating method ■ Easy operation ■ Excellent durability *For more details, please refer to the PDF materials or feel free to contact us.

The "AH-B" can be used as a hot air generator for food heating, paint drying, fiber drying, deodorization devices, and heating devices. 【Features】 1. Maximum hot air temperature of 800°C. 2. Equipped with a burner that can handle high furnace pressure conditions. 3. Energy-saving as it can accommodate hot air return temperatures up to 350°C. 4. Utilizes highly reliable combustion equipment, with an automatic safety combustion device included as standard for safety. 5. Compactly integrated piping equipment that excels in maintainability. 6. Customizable design according to usage conditions. 7. An indirect hot air type (AH-BX) with an external heat exchanger is also available. For more details, please refer to the catalog.

【Features】 ◇ It is a packaged type that is pre-assembled in the factory. ◇ It achieves a thermal efficiency of 90%. ◇ It is compatible with high-temperature hot air circulation in the heat dissipation line. ◇ It has high maintainability, equipped with inspection doors in various locations. ◇ The gas burner is equipped with safety devices such as automatic ignition and flame detection, allowing for safe use.

The "hydrogen-only specification" of the pre-mixed duct burner series, which has a proven track record as a heat source for hot air generators, has made its debut. It is a decarbonized gas burner that achieves both stable combustion and low NOx performance. 【Features】 1. Hydrogen combustion gas burner that emits no CO2 during combustion. 2. Unique casing structure that balances durability and combustion performance, with a turn-down ratio of over 20:1. 3. A lineup of combustion capacities up to "465 kW." 4. Clears emission regulation values through low NOx combustion technology (tested with our equipment). 5. The ignition pilot burner is also equipped with a hydrogen-only specification. 6. Can be replaced with existing burners. As a heat source for hot air generators, it can be used in painting drying ovens, food drying ovens, various drying furnaces, drying equipment, and heating furnaces. Hydrogen combustion demonstrations are currently being conducted at the Thermal Technology Research Institute. We invite you to visit.

By installing a heat exchanger in the existing paint drying oven and recovering the exhaust heat from the oven, the combustion air for the burner is preheated. The temperature difference from the preheating of the combustion air contributes to energy savings.

In our company's thermal technology research institute, we have a hybrid painting and drying test furnace (Quick Curing System: QCO) that can accommodate various sizes of workpieces, as well as a complete painting booth and guns! We can conduct various thermal equipment studies, including painting and drying. Additionally, we have recently made it possible to heat the hot air zone of the painting and drying furnace (QCO) using a hydrogen burner. With simple operation, it is possible to switch between LPG and hydrogen for combustion.
