Company Profile

Established in 1952 as Aero Research Instruments in Chicago, Illinois, ARi was one of the first companies to use mineral insulated cable technology to improve product performance and reliability. That same technology has been improved and refined over the years and is the heart of a wide variety of products that ARi/OMC manufactures today. ARi is a member of the Okazaki group of companies since 1980. ARi manufacturing facilities are located in Addison, Illinois. OMC manufacturing facilities and corporate offices are located in Japan.

ARi/OMC is recognized as an industry leader and quality supplier of metal sheathed mineral insulated cable. ARi/OMC is also a leading supplier of mineral insulated heater assemblies and cable. AerOrod^® high watt density heaters can supply up to 150 watts per square inch yielding quick response and long heater life in even the toughest applications. By using internally welded transitions between the hot and cold sections, possible cold end failures are greatly reduced. ARi/OMC heaters are used in semiconductor processing, furnace element manufacturing, aerospace and heat tracing applications.

ARi’s quality management system meets the requirements of ISO9001-2000 as certified by Lloyds Register Quality Assurance.
