For new-build projects of large chemical plants Venti Oelde offers centrifugal fans with a tandem drive. This necessitates a relatively low investment and reliably prevents downtime which can cause production losses amounting to several hundreds of thousands euros daily.
The tandem drive consists of two drives: a medium or high voltage motor to start up and a steam driven turbine for continuous operation. As soon as sufficient steam is available the plant automatically switches over to the steam turbine. For the reverse, technically sophisticated action from steam turbine drive to the electric motor the manufacturer uses a special coupling configuration which limits the torque peaks to a defined, maximum permissible torque. The tandem drive has for many years proved itself to be successful on a daily basis in large plants all over the world. A further plus, mainte-nance work can be carried out on the inactive drive while the plant is in operation.
