Heat generators for grain dryers, 0.5–5 MW
HELIX 0.5–5 MW grain dryer heaters: indirect heating through our own heat exchanger, minimum maintenance and manufacturer-led selection.
Heat for your grain.
Flue gases kept separate.
HELIX heats drying air through a heat exchanger. Our own design combines separate flows with an approach focused on minimum maintenance.
Flue gas circuit
- Biomass combustion
- Flue side of the exchanger
- Separate flue gas outlet
Drying air circuit
- Incoming air
- Heat through metal walls
- Heated air to the grain dryer
Minimum maintenance. Maximum time to work. According to HELIX Energy, the heat exchanger is designed to operate without clogging or routine manual cleaning of its heat transfer surfaces. Fuel requirements, operating conditions and inspections are agreed for each installation.
Data needed for selection
Selection requires the dryer model, operating airflow, inlet and heated-air temperatures, system resistance and duty cycle. Crop, initial and target moisture, throughput and grain quality requirements also matter.
HELIX model range
Available output classes are 0.5, 1, 1.5, 2, 3, 4 and 5 MW. Explore the heat generator catalogue or use the heat load calculator for a preliminary estimate.
Fuel and configuration
Configuration is selected for wood chips, wood or agricultural pellets and other agreed biomass. Fuel moisture, size and ash properties influence the furnace, feeding and cleaning. Price depends on the agreed equipment package.
Dryer integration
Indirect heating transfers heat through an exchanger wall. Integration checks cover airflow, fan pressure, connections and control signals. Installation and commissioning are agreed for the specific site.
