Controls engineer & PLC programmer in Napa

Strule Automation is an independent industrial controls practice based right here in Napa. If you run a plant in the valley — a crush pad or bottling line, an aggregates operation, a water or wastewater site, a food or beverage process — and a control system is costing you uptime, you don't need to wait days for someone to drive up from the Bay or down from Sacramento. We're local.

The work is PLC programming, HMI and SCADA, fault-finding and optimization: the brains of the plant rather than the pipework. We're vendor-neutral and don't sell a hardware line, so the advice is about your process, not about something we're trying to move. That independence matters most when a fault sits in the seam between two vendors' equipment and each one says it isn't theirs.

Serving Napa and the towns around it

We cover the city of Napa, American Canyon, and out through the valley to Yountville, St Helena and Calistoga, plus neighbouring Sonoma and Solano County sites. If you're near the Napa County line and not sure whether you're in range, just ask — we travel for the right job, and a lot of the first look can be done remotely.

An honest first conversation

Controls work is diagnostic; nobody can promise a fix from the parking lot, and anyone who does is guessing. What we can do is come look, tell you plainly what we find, and be straight about which problems are worth chasing in software and which want a wrench or a purchase order. The first conversation is free.
