Indirect-type Hot Air Generator

1) Generating hot air for drying and heating process by burning oil or gas 

2) Hot air temperature: 60-250 degree C (adjustable) 

3) Heat output: 10,000-3,600,000 kcal/hour; 

4) Temperature control accuracy: +/- 10 degree C 

5)  Applied fuels: heavy oil, diesel, natural gas

RLY series industrial hot air generator is oil or gas fired indirect shell type hot air heater which has been widely used in drying and heating process.

This horizontal type industrial hot air generator consists of combustion chamber, heating jacket with fins, heat insulation, blower and burner. The Riello Burner jets the flame into the combustion chamber which is surrounded by heating jacket. Clean cold air is blown into the heating jacket to get clean hot air. The three-way pass heating jacket with fins welded on it can considerably increase the heat exchanging area and time.

1) High heat efficiency: special designed labyrinth type heating jacket and fins can considerably increase the heat exchange area and time. 

2) Stable heat output and temperature: The combined two-stage flame RIELLO burner can make stable heat output and temperature. And cold air flow rate can be accurately controlled 

3) Long-life span: The combustion chamber is made by heat resistant carbon steel and insulated by 80mm mineral wool. Outer surface body temperature is less than 40 degree C.
