The CENTURION Industrial RSO range has been designed to safely automate extremely heavy roller-shutter doorssuch as entrances to factories and loading bays. Each model is equipped with a heavy-duty electric motor that, coupled with a powerful gearbox, delivers maximum lifting force. In addition, a convenient manual override facility comprising a five metre chain ensures that the door can be operated even in the event of a power failure. A three-button wall pendant allows the operator to not only open and close the door but also safely stop it should an emergency situation arise. The RSO9 is a heavy duty roller-shutter operator utilising a 380V, three-phase power supply enabling it to lift very heavy roller-shutter doors weighing up to 900 kilograms.
