Company History – Sterling Systems & Controls, Inc.

The founding personnel worked for National Manufacturing in Sterling, IL, within a controls department in 1971. They separated from National in 1972 and, as a result, Sterling Systems & Controls was established. One of the first systems completed was a batching system for an agricultural fertilizer facility. This batching system utilized continuous batching technology and was completed in the early 1970’s. Process automation of Animal Feed Mill and poultry processing facilities became a focus, expanding to include Animal Feed, Baking and Food Processing, Pet Food, Chemicals and many other agricultural and industrial processes.

Sterling Systems & Controls was bought by the owners of Prater Industries, Inc. in 1987. Sterling Controls supplied electrical process controls and automation for products that Prater manufactured. This allowed Prater to provide complete system solutions, e.g. grinding, pulverizing, material handling, and batching systems. As a result, the combination of Prater’s equipment and Sterling System & Controls proved very successful for customers needing complete process systems. In 2000, Sterling Controls, Inc. changed its name to Sterling Systems & Controls, Inc. emphasizing the company’s real focus, “Systems”, including process equipment, electrical controls and process automation. The full capabilities of Sterling Systems & Controls, Inc. are best reflected and promoted as Automation * Batching * Process * Systems.

Industrial Magnetics, Inc. purchased both Sterling Systems & Controls, Inc. and Prater Industries in 2014. Since 1961, Industrial Magnetics has been a leader in manufacturing innovative, engineered permanent magnet and electromagnetic solutions. Today Sterling Systems & Controls, Inc. is a proud part of the International Process Equipment Company (IPEC) family, which also includes Prater Industries and Industrial Magnetics (IMI).
