Introduction of 【Electric/Hydrogen/Gas】 Hot Air Generators 【Wide Range of Lineup】
AH Series
We propose a suitable "hot air generator" for your drying equipment. [It can be used for painting drying, food drying, heating furnaces, and various industrial furnaces.]
The hot air generation device can be used 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, making it suitable for a wide range of applications. 【Feature 1】 We offer a variety of heat sources and heating methods. ○ Gas type (compatible with city gas, propane gas, and hydrogen gas combustion) ○ Electric type (capable of achieving outlet temperatures equivalent to gas combustion type with clean hot air) ○ Indirect type (clean hot air using a heat exchanger) 【Feature 2】 We have a rich selection of combustion volumes and heater capacities. ○ Gas type: 47kW to 2300kW ○ Electric type: up to 470kW 【Feature 3】 (Model in parentheses) Flexible selection tailored to drying equipment is possible. ○ You can choose "clean hot air" that does not contain combustion exhaust gases, whether gas or electric type. (AH-BX, AH-E) ○ It can also accommodate high furnace pressure. (AH-B) ○ High-temperature hot air up to 800℃ (AH-B) ○ Hot air return is possible (AH-B, AH-D, AH-E) ○ Design can be customized according to the installation location. (All AH models) ○ Various safety devices are standardly equipped. For more details, please download the catalog or contact us.

basic information
~Lineup~ 【AH-B】Gas-fired hot air generator (High temperature and high pressure type) A hot air generator that accommodates special specifications such as "maximum hot air temperature of 800℃," "blast furnace pressure environment," and "indirect hot air using a heat exchanger." 【AH-C】Gas-fired hot air generator (Premixed type) Since it uses a premixed method, it achieves stable complete combustion flames, and adjusting the heat output is easy. 【AH-D】Gas-fired hot air generator (Post-mixed type) Withstand high temperature circulation (350℃)! The post-mixed method eliminates the risk of backfire and allows for high-efficiency combustion heating. 【AH-E】Electric hot air generator An electric hot air generator that supports a maximum hot air temperature of 250℃ (hot air circulation possible). It can be replaced from gas combustion types and contributes to decarbonization and low carbonization! 【MH】Mini heater series Compact and high-power drying! Automatic ignition with just one switch! By simply connecting gas and electricity, you can easily generate hot air. ■ Baking ovens (metal coating, plywood, resin, etc.) ■ Drying ovens (drying of fibers, food, printing, metal dewatering, etc.) ■ Heating furnaces (preheating furnaces, pretreatment furnaces, foaming furnaces, heat-set furnaces, oil baking furnaces, etc.) ■ Deodorizing devices (direct combustion, catalytic types, etc.) ■ Various other hot air treatments

Company information
Since its establishment in 1959, Seiei Manufacturing Co., Ltd. has supplied gas burners and industrial furnaces to various fields. Leveraging the "combustion technology" and "thermal utilization technology" developed during this time, we are working on the development of "hydrogen and ammonia combustion technology" and "low-carbon thermal equipment." At the "Thermal Technology Research Institute," we can conduct combustion tests of hydrogen gas burners, as well as tests for painting drying and aluminum melting using hydrogen combustion. Additionally, we can perform various tests to solve issues related to thermal equipment. As professionals in thermal equipment, we are committed to contributing to the realization of carbon-neutral manufacturing.
