Ridder RW 240 Series

The Ridder RW240 motor gearboxes are maintenance-free, compact power units for driving ventilation, screen, hoisting and flap ventilation systems in greenhouses and barns.

All Ridder RW240 motor gearboxes feature a self-braking worm gear transmission.  This transmission ensures that the output shaft is braked when the drive unit is stopped. The combination of carefully matched pinion and worm reductions results in a very quiet mechanical transmission.

The Ridder RW240 motor gearboxes feature a patented integrated lineair limit switch system with duty and safety switches having a great switching precision. The maximum switching range of the limit switch system equates to 86 revolutions of the drive shaft. Using the optional installation set with potentiometer, it is possible to precisely feed back the positions of a drive system to a (climate) computer.

The Ridder RW240 motor gearboxes are finished with a graphite gray powder coating and are supplied including fixing bolts and spring washers.
