About:
For twenty years now Design Engineering, Inc.™ has been known for producing exceptional quality heat control products primarily sold through the performance distribution system. But there's another facet of our business that we specialize in - working with other customers to help solve their heat and sound control problems. We work with these customers to define their problem, determine the correct materials necessary to handle their heat or sound control issues and work to design a solution. Our in-house design team can quickly turn around first article prototypes for inspection, for fitment and evaluation purposes. Once a final design is tested and approved by the customer, production begins based on their requirements. Over the years we have designed custom solutions for many industries and fields including, aviation, powersports, racing, marine and eve, locomotive. We have also produced "build to spec" contract work for commercial, industrial and military related businesses to name a few. All of these businesses who decide to contract Design Engineering for heat and sound solutions have recognized our capabilities and ability to come up with correct and innovative products to solve the problem. Our Beginnings The late Dale Markley, well known and long time performance industry veteran, founded DEI in 1995. Dale and his wife Nancy formed the company with a vision of developing dynamic solutions for the racing and performance industry's ongoing struggle with underhood, power-robbing heat issues. The business was started in a small space, located in Cleveland, Ohio, behind a convenience store, and within a few years had to double the space. Before Dale's passing in 2001, he and Nancy worked together and brought DE and its "Thermal Tuning Products" to a whole new level. Fueled by success and further growth, it was necessary to expand operations, and in late 2004, DEI relocated from its leased location to its newly acquired complex that houses office, warehouse and manufacturing operations. The new facility afforded DEI ample room for future expansion and, in fact, manufacturing and warehouse expansion plans were quickly underway. Today, DEI is bigger, stronger, and "cooler" than ever. With Dale's son David at the helm, the family is committed to continuing Dale's vision of moving DEI forward by developing and improving products to ensure they remain industry leaders. We are Design Engineering "At Design Engineering, Inc, YOU the customer, are behind every decision we make. We try to look at every product and service we offer from your perspective.
