Projects our engineers have delivered
A few projects from our engineering team. We describe customers by industry and application, never by name.
Freelance DCS control panels for a high-power test facility
I/O and electrical design from the customer's I/O list, S800 I/O over PROFIBUS, staged delivery and as-built terminal maps; programming and commissioning under way. 2025–2026.
More than fifteen years of DCS support at a chemical plant
Panels, I/O migration, Freelance programming, shutdown support, training and care agreements. 2009–2026.
Freelance controls for a cultures producer's freeze dryers
Built in 2022–23 and maintained hands-on; an extension for another dryer, reusing the original design and code, was ordered in 2026.
S800 I/O supply and support for an oilseed processor's DCS
S800 I/O quoted from the plant's own parts list, same-day engineering support during an outage start-up, and an analog input expansion. 2025–2026.
Machine power-monitoring hardware for two IIoT deployments
Monitoring kits, gateways, approved schematics, cable schedules and Modbus maps behind a software partner's platform. 2026.
Relay-panel equipment package for a municipal substation upgrade
Specification review, sourcing and an engineered nameplate package, won on sealed bids. 2025–2026.
Field service, repairs and small retrofits for local manufacturers
On-site PLC troubleshooting, a drive retrofit and small panel builds. 2022–2026.
Where our panel shop began: a 32-axis motion retrofit
The project that gave us an engineering group and a panel shop. 2007–2016.
Panels from our UL 508A shop
Every panel our engineers design is built in our own UL / cUL 508A listed shop. Panel-shop case studies are on grossmfg.com.
Test-cell power and control line-up for a factory drive test floor
Eight assemblies, 690 V and 480 V, PLC/HMI programming and on-site commissioning. 2025.
Long-running controls supply for a dairy and farm equipment OEM
Pre-programmed operator panels and drives, depot repair and an obsolete-drive cross-reference. 2012–present.
UL 508A control box for a robotic work cell on a deployment deadline
Designed around the customer's safety and control kit and inspected by UL in our shop. 2025.
All panel-shop work
Utility network cabinets, generator alarm panels, transfer-switch enclosures and more.
