DECCO® – Over 100 Years of Leadership

Known as Detroit Coil Company, or DECCO® , the company was founded in 1912 to supply high-quality coils and solenoids to a variety of industries and industry-specific applications. Detroit Coil Company, a family operated business, was known for providing electro-mechanical actuators to Ford Motor Company for starter solenoids in Ford’s flagship vehicles, the Model A and Model T. The DECCO® trademark quickly became recognized as the representative for high-quality industrial grade solenoids and state-of-the-art coil technology. The company developed into an international supplier of laminated solenoids with a subsidiary in the United Kingdom and manufacturing facilities in Michigan.

DECCO® Becomes Employee Acquired

In the early 2000's, the Oil Immersed and Air Packaged solenoids demonstrated DECCO® ability to develop products for a broad range of different applications in a variety of industries. As this family owned business matured, several spin-off companies were developed, and ownership of the parent company was transferred to an employee-based management group. Late in the decade, the company was tested by challenging market and economically unstable times.

ROSS CONTROLS® Acquires Detroit Coil Company – ROSS DECCO® is Born

In 2012, ROSS CONTROLS®, an industry leader in pneumatic and hydraulic valves, control systems, and safety products for the fluid power industry, acquired Detroit Coil Company. The name of the company was then changed to ROSS DECCO®, maintaining the highly recognized DECCO® brand and trade name. ROSS® and DECCO® have collaborated in the past as DECCO® has supplied components to ROSS® for many decades. Both companies have long histories and an unmatched reputation for innovative design and manufacturing solutions.
