However, we are a real company, with real people, and a real building. We are open weekdays from 7:00 am to 4:30 pm, Central Time. We would welcome your call, if you wish to talk to someone about a problem, application, or with a question.


Our Specialties

Steel And Paper Mills


We have a long history serving steel mills and paper mills in the Southeast. We offer various sensors, valves, and controls for detecting and controlling temperatures, pressures, flows, and production speeds within these heavy duty industries. Maxon Corporation is our oldest partner and known worldwide for their reliable, high performance gas burners and valves, including safety shut-off valves.

Municipal Water Treatment


We have been fortunate to be involved with Georg Fischer and their partnership with Orica, a company from Australia that has developed an environmentally friendly water treatment process. Referred to as MIEX Resin, the process utilizes a magnetic ion exchange which prevents toxic trihalomethanes from existing in drinking water. The system is currently in use at five water treatment facilities in Alabama.



We have been in the instrumentation and controls business for all of our 80+ years. Providing simple on-off controllers to complex multi-parameter systems, we have devices for steel & paper mills, water treatment, bottling & canning, foundries, iron, steel, & plastic pipe making, food handling, mining, and more recently, automotive manufacturing.


Gems Sensors & Controls

Gems Sensors is known for their wide range for level, flow, and pressure switches and transducers. They offer products designed to withstand the harshest environments, which is why they are the preferred sensor for military ships in the United States Navy. We offer these same sensors to help our customers solve industrial and commercial flow, level, and pressure applications


The BaumerHubner product line represents a joint venture in Europe that provides various heavy-duty encoders for steel and paper mills. These units already have a world class reputation for durability and reliability in harsh, demanding environments. We have added the BaumerHubner line, so we can support our customers using and maintaining European built machinery.


Having been a distributor for Ogden Manufacturing for 20+ years, we were pleased to be added to the Chromalox family of distributors when they purchased Ogden. Joining together Chromalox and Ogden greatly increases the capabilities and product offering for both these companies. In time, the Ogden brand name will be discontinued, but their products and support will continue to be available through Chromalox.


Encoders, resolvers, and speed detection is now a mainstay requirement for modern manufacturing and material handling processes. As movement and speed requirements have become more relavent, being able to accurately monitor those requirements has become commonplace. Dynapar, which now includes popular brands like Northstar, Lakeshore, Hecon, Hengstler, Acuro, and Harowe, can offer solutions for any application.
