c) Construction internal
Electrical equipment is located in an internal distribution box and the rotor unit is attached to
this by a quick release connector. The rotor unit contains the rotor (6), drive motor (7), drive
belt (8), heating element (15) and covers (12,13), that is to say all internal components close to
the fan (3).
The parts referred to in the schematic images are described in more detail below.
(5)
Elastically secured removable ”drying pack”
(6)
Drying rotor with hub, bearing, spokes and blades
(7)
Drive motor with pulley for drive belt
(8)
Toothed drive belt
(9)
Rotor seal that forces air to pass through the drying rotor
(10)
Process air fan. There is a grille and filter between the process air fan and the process
air inlet (3)
(12)
Heat cover that traps part of the process air for regeneration of the drying rotor
(13)
Collection cover for wet air
(15)
Heating element
(20)
Rotor stay to secure the rotor in the drying pack. The rotor shaft is secured in the
middle of the rotor stay
(21)
Bent panel to facilitate air flow and thereby reduce flow losses
