Model RW800 - Motor Gearboxes

From

0

The RW800 motor gearboxes are maintenance-free, compact drive units for operating ventilation, screen and lifting systems in greenhouses and livestock houses. All RW800 motor gearboxes feature a self-braking worm gear transmission. This transmission ensures that the output shaft is blocked when the drive unit is halted. The combination of carefully matched pinion and worm reductions results in a very silent mechanical transmission.

RW800 motor gearboxes feature a patented integrated linear limit switch system with duty and safety switches, giving excellent switching precision. The maximum switching range of the limit switch system equates to 120 revolutions of the drive shaft. The optional RPU PositioningUnit accurately monitors the current position of a drive system and transmits this data back to your climate computer or controller. This position feedback can also be achieved using an installation set with a potentiometer.

RW800 motor gearboxes are finished in graphite-grey powder coating, and are supplied complete with fixing bolts and spring washers.
