Are You Leaving Your Surplus FA Inventory Idle? A Strategic Guide to Selling Used Factory Automation Parts
From PLCs, Inverters, and Servos to HMIs and Sensors — RotomTech provides comprehensive support, from complimentary appraisals to immediate payments.
A common sight in many facilities—but leaving them idle means their value depreciates every single day.
Those boxes of FA components kept under the assumption that they “might be useful someday”—haven’t they remained in that exact same spot for the past year or two?
When automation lines are overhauled or equipment specifications change, it is common for fully functional PLCs, inverters, and servo motors to end up sitting idle in a warehouse. While scrapping them feels like a waste, navigating the process of where and how to sell them can be quite daunting.
RotomTech is a premier B2B FA parts procurement specialist, dedicated to recirculating these idle assets back into the supply chain at their fair market value. Simply send us a photo of your inventory, and we will provide an initial estimate within 24 hours. We offer a seamless process, with all appraisals and shipping provided entirely free of charge.
