The operation of the hatches is mechanized. It is possible to operate several hatches with a single hatch motor. With the Mooij Hatch operation the air inlet and the air outlet hatches are opened and closed. The hatch motors are featured with a gearbox with two output shafts. On both shafts rack and pinion sets are mounted for multiple hatches.
Inside the housing two limit switches for the position “ open” and two for the “ close” position are built-in.
