Founded in Wilmington in 1954 as Master-Port Feed Mills, D&E Equipment designs, fabricates and installs grain storage and material-handling systems for agricultural operations. The company has served Southern Ohio, Northern Kentucky and West Virginia for nearly 70 years, pairing CAD-based project planning with its own millwright, bin-erection and electrical crews. D&E also supports the equipment it sells with factory-trained service personnel, an extensive parts inventory and in-house repairs.
