Helical combustion chamber
The high cylindrical chamber forms a longer gas path and a controlled spiral motion. This improves burnout of volatile fractions and pushes the hot core of the flow toward the heat-exchange surface.
Lower fouling on difficult fuels
Sunflower husk, straw and mixed agri residues tend to create unstable combustion and sticky deposits in weak chamber geometry. HELIX is engineered to reduce these risks and keep the service interval predictable.
Stable process air
The heat exchanger keeps flue gases separated from process air. Grain gets clean heated air in the required temperature band, typically 40–160 °C, with stable control.
Automation and controls
Siemens S7-1200 PLC, variable speed drives, PID loops and oxygen-temperature logic allow precise control of the thermal process under changing fuel quality.
Why it matters commercially
For the customer this means lower operating cost, fewer emergency stops, easier operator training and more confidence during the peak of the drying season.
