direct air heater

  
 

Hot air generation with direct air heater
The direct air heater consists of an outer casing, an intermediate casing against radiation
losses and a perforated combustion chamber made of highly heat-resistant steel, arranged
centrically in the casing. The hot combustion gases are mixed with the fresh air heated up
at the side of the combustion chamber and hot air of homogeneous temperature is
generated. So the energy from combustion is directly fed into the drier. This method is
applied above all for the drying of feed and industrial raw products.

The firing efficiency is 100 %.

Oil or gas fan burner
We only use quality burners of the leading European manufacturers for the hot air generation with fan burners. Depending on the heating medium and demand on the control behaviour, you can choose from different designs:
• one, two, three-stage or infinitely variable (modulating)
• light and heavy fuel oil
• natural or liquid gas
• on demand, as blue burner in most modern emission-reduced design
• also for bio diesel or biogas
 
 
 

Gas line channel burner for direct air heating
As alternative for the direct air heater with gas fan burner, often gas line burners are used.
Here the burner is installed into a heating duct integrated into the hot air cap.
 


 

 

• for natural or liquid gas
• control range up to 25 : 1
• firing efficiency 100 %
• ideal air mixing and thus
  homogeneous hot air temperature
• space-saving
• no upper capacity limit
• no combustion fan necessary
• robust and maintenance-low
 

 
 
 





 

 

Further information
 Of course, we equip our driers also with steam or special heating.
