Industrial Fan for High Temperature
Industrial centrifugal fan used for hot air circulation (250°C during operation, with peaks of 350°C) within a furnace for the baking of ceramic slabs.
V (m3/h) = 5.500
Pt (Kg/m2) = 5860 Pa at 250°C
Fan made of robust carbon steel S 235 JR, impeller made of COR-TEN with blades on the rear side, equipped with cooling fan. Arrangement 12, with belt drive.
The centrifugal fan was insulated by a layer made of ceramic fibers and mineral wool within aluminium sides.
Epoxy painted WEG Electric Motor 250 M4, 55 kW, 4 poles, IP55, mounting B3, V 400/690/50, efficiency IE4.
The fan was conceived and designed to replace an existing one, already installed for several years in the production process, but almost at the end of its lifecycle. The current fan is installed on a mezzanine, connected in suction and discharge to the plant through very thick steel pipes with PN16 flanges, which could not be modified.
