Ariterm - Dual Feeding Screws System
The feeding screws used in the Ariterm bio burning systems are made of steel and designed to endure the strain caused by different fuels. The right choice of screws is a critical factor when deciding the faultless functionality of the bio heating system. In a dual screw system there is more leeway in positioning the boiler and the storage in relation to each other. The free fall funnel can also be ordered with special measurements, so that the devices can be positioned to fit the operating space.
The dual screw system is recommended because it has a better burnback protection. The free fall funnel between the screws forms a flame-retardant, fuel-free space between the storage and the burner. The funnel, along with the rising burner screw, enables the formation of a water lock in a case of a burnback.
The transmission of the feeding screws is dimensioned according to the size of the screws and the chosen fuel. The motors and gears are maintenance-free worm gears and conical cylinder gears.
