What Electronic Systems Design does
Electronic Systems Design, Inc. (ESDI) is a privately held US manufacturer of electronic control systems for the water industry, founded in 1978 and headquartered at 1010 North Maclay, San Fernando, California. The company designs and produces a portfolio of OEM controller boards for water vending machines and reverse osmosis (RO) water purification systems, plus custom electronics design and manufacturing services for adjacent industrial applications. ESDI holds US Patent 6,495,983 for the Robomotor, an integrated motor assembly that records and plays back motion, functioning like an audio/video recorder for mechanical motion rather than sound and images.
ESDI's product line spans single-price and multi-price water vending controllers (e.g., Model 030400, 110100A, 110150A, 170258, and the 110400-NOM and 110400 series for up to four vend stations) and RO system controllers (Model 250C, 258, 500, 503, 190100). Notable technical features include NAMA Multi-Drop Bus (MDB) protocol compatibility for payment device integration, TDS continuity monitoring, automatic membrane flush cycles with switch-selectable timing, pump run-time hour metering, flow-sensor-based vending with calibration from 1/2 liter to 6 gallons, and UL-508, IEC 1000-4-4, MIL-STD-2000, UL-325, and UL-991 compliance. All products carry a two-year warranty and are designed and manufactured in the USA.
ESDI operates a B2B, sales-led go-to-market, selling quote-based hardware directly to OEM manufacturers that build water vending machines and RO systems, with direct engineering support as the primary customer touchpoint. Revenue derives from hardware sales of standard controllers, custom electronics design and manufacturing services (covering solar, gate operators, access control, industrial automation, and aerospace applications), and licensing of the Robomotor technology. The company markets primarily through its website, which serves as a detailed product catalog with specifications, data sheets, manuals, and wiring diagrams available for download.
