Many industrial processes use Allen Bradley (AB) PLC s. The plants often feel they are stuck with using the Allen Bradley equipment even for add-ons due both to the complexity of the Allen Bradley networks, and the cost of a new network . Not to mention that their existing AB PLC network is stable and reliable.
You did your homework, researched the various manufacturers, checked out the features to ensure the product will meet your needs, and made your purchase. However, did you consider service after the sale?
At EMA we start a LOT of VFDs , and on top of that, we help a lot of others start VFDs over the phone.
EMA has a lead on an unused 4160 volt 7000 HP Toshiba T300MVi medium voltage VFD for sale.
EMA is a major repair center for VFD s of nearly all brands. While the cost of new VFDs has made repairing smaller units uneconomical at times, our repair shop continues to repair VFDs in considerable numbers, especially high horsepower VFDs.
EMA is in the process of refurbishing and modifying a set of medium voltage VFDs, changing them from a 3300 VAC input to a 4160 VAC input.
With the advancements in technology, VFD manufacturers have made low voltage VFD’s user friendly and interface-easy to a point that most electrically inclined customers can start up their own low voltage VFDs. This is not the case on Medium Voltage VFDs. The potential for damage to the equipment and personnel could be huge when it comes to Medium Voltage VFDs. This equipment is sophisticated enough to require a professional start up.
A VFD can be used as a softstarter. Medium and low voltage softstarters are less expensive than medium or low voltage variable frequency drives (VFD) . If a softstarter will do the job, then that’s often all you need. However, at EMA, we’ve seen situations where a softstarter was purchased and installed, only to discover that it would not start the load. Here’s why.
EMA has acquired 9 1000 HP medium voltage Toshiba T300MVI VFDs. We are refurbishing and testing the units, which will carry a full warranty. We expect to have the first two ready to ship on or about November 20th.
EMA began as a service company, doing drive and VFD service for a national customer base. At first, we rarely stocked any VFD equipment, although we did usually carry VFD parts. However, we now stock a large number of both low voltage and medium voltage VFDs, available for immediate shipment.
