About
OTC Industrial Technologies — operating in Phoenix under the Keller Electric and AAP Automation brands — is an industrial-focused electrical and automation distributor and service provider serving commercial and industrial facilities across the Phoenix metro from its location at 1881 E. University Drive. With emergency service capabilities and a broad portfolio spanning engineering, design, and maintenance repair, OTC is positioned to support facility managers and plant engineers who need a single-source partner for complex electrical and automation challenges. The company's service scope covers power distribution and control solutions, motor control, automation systems, and fluid power — making it a strong resource for manufacturing plants, food and beverage processors, pharmaceutical facilities, water and wastewater operations, and general industrial sites throughout the Phoenix region. OTC's integrated company structure — combining Keller Electric's electrical expertise with AAP Automation's controls capabilities — gives facility and operations managers access to cross-disciplinary teams who can handle everything from panel-level troubleshooting to full system integration and startup. This is particularly valuable in Phoenix's growing industrial corridor, where aging equipment and capacity expansion often demand both electrical and automation competency on the same project. Industries served include automotive, chemical, agriculture, OEM manufacturing, power and utility, and steel — covering the breadth of heavy commercial and industrial facilities common to the greater Phoenix market. With an emergency service line and a multi-location national presence through OTC Industrial Technologies' broader network, multi-site facility managers can leverage consistent service standards across multiple properties. Facility managers and plant engineers managing critical uptime requirements will find OTC's combination of product supply, engineering support, and field service maintenance a practical resource for Phoenix-area industrial electrical and automation needs.
