Control Techniques DFS Saves the Day

Summary:

Due to the pre-engineered design and inventory in the US, the Control Techniques Unidrive DFS (Drive-Free Standing) series is ideal for replacing failed stand-alone VFD cabinets.

Solution:

Recently an Applied Controls customer called in looking for a replacement for a 250 HP VFD that failed.  The VFD power a regenerative thermal oxidizer (RTO) fan which shut down their entire paint line.  Obviously, they needed to get back up and running as quickly as possible.  The vendor of the original VFD did not have the drive-in stock which is why the customer then reached out to Applied Controls looking for a solution.

The VFD was installed in its own NEMA 12 enclosure so the quickest solution was to replace the entire enclosure and wire up to the existing power line and motor leads.  Control Techniques had a 300 HP Unidrive DFS in stock and was able to ship it out next day.  The customer had already removed the old VFD enclosure and was able to quickly drop the DFS in the existing space, land the power and signal wires, and commission the drive for operation.

With the Control Techniques Unidrive DFS and Applied Controls’ helpful and responsive customer service, you can minimize downtime in the event of VFD failure.
