Ventilation systems for pellet stoves - SPG

THE FUNCTION OF THE FANS IN PELLET STOVES

The heating system of pellet stoves is designed with the aim of producing hot air by burning pellets.

The pellet is contained inside the stove in a tank; the screw conveyor, driven by a gear motor, picks it up and lets it fall, via a slide, inside the burner. Here the pellet comes into contact with the flame and combustion takes place.

The residual fumes produced by combustion are forced into the heat exchanger and then channeled and expelled by the fumes suction fan.

The clean air, on the other hand, is sucked in by another fan (centrifugal or tangential); it passes through the heat exchanger in different pipes becoming hot, and then it is diffused into the environment through the vents located in the front of the stove.

FANS FOR SPG PELLET STOVES

Designed to complete the range of products suitable for manufacturers of pellet stoves and boilers, Garnet has specific external rotor fans for the extraction of fumes from our representative SPG.

The intrinsic characteristics of the external rotor construction of these fans for pellet stoves allow to reduce the axial dimensions to a minimum, ensuring optimal performance in terms of flow rate, head and noise.

The position of the motor also ensures optimal ventilation.

The SPG smoke extraction fans are made of pressed steel sheet which ensures perfect operation over time; the impellers are in stainless steel and the motors are equipped with a sensor, to allow the control electronics to adjust the speed.

Garnet has fans for the extraction of combustion fumes with steel impeller diameters from 150 mm to 210 mm, with and without volute.

There are also centrifugal or tangential fans for the diffusion of hot air into the environment, equipped with an external rotor or shielded pole AC motor, available in different sizes.
