NO DOWNTIME BETWEEN CROPS

Instant, electronically controlled follow on without
the need for emptying and re-filling.

PRECISE FLOW CONSISTENCY

Plus the mechanical flow avoids streaming, and
complete bed inversion.

STEPLESS AUTO SPEED CONTROL

MECHANICAL CONVEYING

All granular products and nuts are moved within the dryer, meaning no possibility of blockages, bridging or hot spots.

LOW INSTALLATION COST

Mostly pre-assembled, pre-wired and low foundation costs.

MINIMAL ENVIROMENTAL IMPACT

Low profile, low noise (extra silencers
and cladding avaliable).

DUST CONTROL SYSTEMS

Optional dust house to collect dust and chaff.

More Features

High fuel savings compared to other drying systems

Built-in air recirculation for the used cooling air which allows heat from dryer to be re-used, saving fuel.

Further fuel savings can be made with external cladding, allowing even more warm air to be re-used. The dryer can be fully internally insulated, to minimise even more heat loss and reduce the fuel usage when drying with extreme weather conditions.

Easily set for every granular crop

All key drying parameters including bed depth, drying air temperature, residence time (amount of drying to be done), airspeed and maximum grain temperature are fully adjustable from dryer / control panel to allow dryer to be optimally set for each product, maximising efficiency.

Less electrical power consumption

Fully adjustable hot fan speed via electrical inverter technology allows fan speed to be reduced on lighter products, saving electrical energy.

Built-in dust and chaff removal

Built in dust and chaff removal system eliminates the need for separate cleaning system prior to drying to achieve satisfactory and safe drying, reducing any additional electric consumption.

Grain is turned during drying process, ensuring even drying.

Highly automated

Continuous Grain and Air temperature monitoring allows the grain dryer to automatically regulate drying process to maximise efficiency and throughput.

Sensors on grain feed system automatically control grain fill level, minimising running time on intake equipment.

Blockage sensors on all connected equipment minimise downtime in event of system blockage.

Built to last for generations

Proven construction with an anti-corrosion finish and strong epoxy paint.

Backed by a 2 year warranty and worldwide support.
