200kW ventilator-start
(OP)
Hi,
I need some suggestion about how to start 200kW ventilator (400/690V 2 pol or 4 pol)?
I have two ventilators. Ventilator 1 is 200kW and for continuously, when ventilator 1 goes down(defect), ventilator 2 has to start automatically. What is best solution for start so big fans and how to switch automatically if the fan 1 defect.
Switche has to be quickly as possible.
thank you!

If the power source is enought I will start each one DOL.Then
You could install air sensors(Air pressure) in each duct of each ventilator(Fan) to detect if is or not in operation in order to command the backup fan starting. Also you can analize the option of use VFD to obtain energy savings, in this case you can connect the contacts and signals from one VFD1 to give advise to the other VFD2 to operate in case of failure or accidental disconnection.

Soft starter, star-delta or frequency inverter?

I don't look time as time. It has to be safety when changeover is made. Fan 1 has to stop and then fan 2 start. If is that 10 min it will be 10min if 30min it will be 30min.
I look for VFD from Danfoss FC302.
