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

By burning through the burner, high-temperature 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 hot air temperature in the drying system reaches the rated maximum temperature, the burner will automatically stop burning or switch to a low flame. When the hot air temperature drops to the rated minimum temperature, the burner will reignite and operate or switch to a high flame, and the rate of temperature increase can also be adjusted by regulating the inlet valve.

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