What Automation Components, Inc does
Automation Components, Inc. (ACI) is a Middleton, Wisconsin-based manufacturer of environmental sensors for HVAC and building automation, founded in 1991 and acquired by DwyerOmega in January 2024, at which point it became a DwyerOmega brand. The company employs 200+ people across four facilities spanning more than 60,000 square feet, producing over 20,000 part variations and shipping thousands of sensors daily. Its product portfolio spans twelve core lines — temperature, humidity, pressure, current, gas, interface, wireless (MESHNET 900 MHz), BACnet/Modbus, power meters, air quality, smoke/leak detection, and freeze stats — with proprietary differentiators including BTL-certified BACnet interoperability, an ECM Current Switch with the industry's lowest adjustable trip point (0.075A), and double-encapsulated temperature sensors.
ACI's revenue model is hardware sales to two primary channels: (1) catalog and configurator sales to HVAC contractors and building owners via 447+ authorized distributors across the US and 32 countries, plus direct e-commerce at workaci.com with same-day shipping and no minimum order; and (2) custom/OEM manufacturing producing hundreds of thousands of private-labeled sensors annually for partners in refrigeration, medical equipment, restaurant equipment, boiler/chiller, and air handler manufacturing. Published list prices range from approximately $46 for basic temperature sensors to over $6,000 for advanced leak detection controllers, with distributor volume discounts and stocking/blanket agreements for OEM accounts.
The company holds ISO 9001:2015 certification, maintains UL, CE, UKCA, REACH, and RoHS compliance across most product lines, and has won multiple Controltrends and Wisconsin Manufacturer of the Year awards. Technical support, custom engineering, and content-driven marketing (application guides, technical calculators, video gallery, distributor locator) form the operational backbone supporting customer acquisition and retention across contractor, OEM, and data center/IAQ use cases.
