What CSI Controls does
CSI Controls, founded in 1993 and operated as a brand of S.J. Electro Systems, Inc. (SJE), designs and manufactures liquid level and pump control hardware for water and wastewater applications. The brand serves residential, commercial, municipal, and industrial OEM customers across the United States and, through SJE's broader footprint, in Canada, China, and Mexico. Its primary value proposition is reliable pump control and tank-level monitoring at a price point enabled by a multi-brand parent platform and a 5-year limited warranty that is described as industry-leading.
The core product portfolio is organized into three groups: pump control panels (Standard, RK Series with 4-20mA continuous level sensing, Fusion Plus, and ACCEL engineered custom solutions); tank alarm systems anchored by the CSION family (indoor WiFi, Type 3R, and NEMA 4X variants, alongside CS1200 and CS1000 models); and supporting level-sensing and pressure components including float switches, the CS4-20 submersible level transmitter, and the WS360 360-degree water sensor. Manufacturing, engineering, and assembly take place at a 51,000 sq ft UL-listed facility in Ashland, Ohio, opened in 2019, where CSI Controls also runs engineered-custom programs (ACCEL, SJE Panel Link, Rapid Set). Products carry UL/cUL and CSA certifications and are integrated with two product sub-brands, RK Series and Fusion Plus.
Revenue is generated primarily through hardware sales of standard panels, tank alarms, and engineered custom control solutions sold on a quote basis, with multi-year contract pricing available for engineered work. Go-to-market is indirect: CSI Controls does not sell directly to end users, instead reaching installers, contractors, plumbers, wholesalers, and OEM customers through a network of manufacturer representative agencies (OnPoint Sales, TAG, Watermark, among others), wholesale distributors, and a growing regional sales management layer that supports both channel partners and end customers. The brand is 100% employee-owned through SJE, is privately held, and does not publicly disclose revenue.
