Venti Oelde ensures high levels of availability of centrifugal fans in large plants with a tandem drive.
For new-build projects of large chemical plants Venti Oelde offers centrifugal fans with a so-called tandem drive. This necessitates a relatively low investment and reliably prevents downtime which can cause production losses amounting to several hundred thousand Euros daily.
Tandem drive with automatic drive change-over
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 Venti Oelde uses a special coupling configuration which limits the torque peaks to a defined, maximum permissible torque.
Safety right down the line
Venti Oelde meets all design regulations for centrifugal fans and their individual components. The tandem drive has for many years proved itself to be successful on a daily basis in large plants all over the world. Furthermore, test runs and simulations substantiate that specific designs meet customer requirements. A further plus, maintenance work can be carried out on the inactive drive while the plant is in operation.
