Overview
L.W. Allen, Inc. designs, manufactures, and distributes pump and electrical control systems for municipal water and wastewater projects in the upper Midwest. Its in-house Altronex division creates UL-certified control systems that integrate components from brands like Allen-Bradley and ABB to automate, supervise, and monitor pump equipment and flow control, with services that include installation, programming, repair, and 24/7 support. Unlike many competitors, it builds and codes its own control systems in a UL-certified facility and provides end-to-end solutions backed by SJE, Inc. to expand capacity. The company's goal is to grow its capabilities and market reach by delivering customized, integrated pump-and-control solutions for water infrastructure.
