Primarily composed of the combustion system, heat exchange system, control system, and exhaust system.

Through the combustion of the burner, high-temperature flue gas is produced to heat the heat exchanger system. The heated air is then blown into the drying system by a blower. The thermal efficiency can reach 92%. When the temperature of the hot air in the drying system reaches the rated upper limit, the burner will automatically stop combustion or switch to a low flame. When the temperature of the hot air drops to the rated lower limit, the burner will reignite and resume operation or switch to a high flame. The rate of temperature increase can also be adjusted by regulating the air intake valve.

High heat exchange temperature, high thermal efficiency, compact size, stable hot air temperature, long lifespan, and low maintenance cost.
