High-Performance Automation Cabinets & Magnetic Equipment

Engineered for mission-critical reliability across Northern California cleanrooms, robotics facilities, and distribution hubs.

Bay Area Industrial Integration

Meeting San Francisco's Rigorous Automation & Electrical Standards

From the biotech labs of South San Francisco to high-throughput warehousing in the East Bay, procurement teams face intense compliance, space, and seismic constraints.

UL 508A & NFPA 79 Alignment

San Francisco Department of Building Inspection (DBI) and local city inspectors mandate third-party field evaluation or accredited shop labels. Our automation control panels follow rigorous UL 508A guidelines, wire color conventions, touch-safe finger protection (IP20 minimum internal), and selective coordination to bypass costly local re-inspections.

Seismic Bracing & OSHPD Standards

Operating along the San Andreas and Hayward faults requires physical equipment resilience. Our enclosures are built with reinforced unistrut framing, gusset plates, and heavy-gauge cold-rolled steel, designed to withstand high spectral response accelerations (Ss) per California Building Code (CBC) Title 24 Seismic Zone 4 parameters.

Clean Energy & Harmonic Decoupling

With aggressive California PG&E interconnection rules and strict IEEE 519 compliance goals, our control cabinets integrate series line reactors and active harmonic filters. This suppresses total harmonic current distortion (THDi) under 5%, preserving transformer life and ensuring stable power quality for sensitive microelectronics.

Procurement Whitepaper Note: The Short Circuit Current Rating (SCCR) Challenge

A frequent stumbling block for imported panels entering California is a default 5kA SCCR label on complex motor circuits. Hengel/Prima engineers perform detailed short-circuit calculations during schematic design, utilizing current-limiting fuses and coordinated circuit breakers to deliver verified cabinet labels of 65kA to 100kA SCCR at 480V, matching utility fault availability without on-site field rework.

Why Tier-1 Integrators Choose Our Manufacturing Ecosystem

Combining heavy-duty magnetic fabrication, panel enclosure sheet metal engineering, and modern automation design.

Vertical Magnetics Integration

Unlike ordinary panel shops that outsource transformers and chokes, our direct production capability spans custom control transformers from 50VA to 5000kVA and line reactors up to 2500A. This vertical synergy reduces thermal footprint, eliminates component lead-time bottlenecks, and ensures optimal impedance matching.

Computerized Routine FAT Testing

Every automation enclosure leaves our facility backed by an exhaustive Factory Acceptance Test (FAT) dossier. Our facility utilizes automated computerized panels for single and 3-phase testing, open/short-circuit diagnostics, Megger insulation resistance testing, and double voltage double frequency (DVDF) stress checking.

Streamlined Transpacific Logistics

We provide full-container-load (FCL) and consolidated (LCL) freight solutions straight to the Port of Oakland or air cargo directly into SFO International. Cabinets are secured inside moisture-barrier vacuum packaging with desiccant arrays and reinforced wooden crates engineered for cross-ocean transit stability.

Procurement Clarity

Frequently Asked Questions for California Buyers

Essential guidance addressing regulatory approvals, electrical codes, lead times, and engineering change management.

Can you build panels that pass San Francisco electrical field inspections?

Yes. We design and build strictly adhering to NEC (NFPA 70), UL 508A, and NFPA 79 standards. All major components used (breakers, contactors, terminals, wires, power supplies) are UL Listed or Recognized. We can also coordinate with accredited Nationally Recognized Testing Laboratories (NRTL) such as Intertek (ETL), UL, or TÜV for field evaluation labels prior to project handoff.

How do you handle engineering design changes during fabrication?

We utilize EPLAN Pro Panel and AutoCAD Electrical for all electrical engineering. Initial schematic submittals are sent to your engineering team for redline approval. Any subsequent revisions are tracked via structured Engineering Change Orders (ECO), and revised wiring runs are verified using computerized terminal mapping before assembly progresses.

What are the standard lead times for custom control cabinets shipped to California?

Typical engineering submittals take 7 to 12 working days. Once schematics are approved, fabrication spans 3 to 5 weeks depending on component sourcing. Sea freight from origin ports to Oakland typically requires 14 to 18 days on water, offering an overall timeline 40% faster than standard domestic fabricators facing component backlogs.

Do your switchgear and cabinets support remote monitoring and telemetry?

Absolutely. Our panels can be specified with IoT edge gateways, managed industrial Ethernet switches, and PLCs configured for MQTT, Modbus TCP/IP, BACnet/IP, or OPC UA protocols. This enables real-time facility telemetry integration with cloud architectures (AWS IoT, Azure) common across Bay Area enterprises.
