Engineered Assemblies & Industrial Systems

Directory of low-voltage switchboard configurations, automatic power factor correction suites, mechanical HVAC plant integration, and standby electrical infrastructure engineered in accordance with BS EN 61439.

Low Voltage Main Switchboard Power Distribution
BS EN 61439-2 • Up to 4000A

Low Voltage Form 4 Main Distribution Switchboards

Custom engineered modular switchboards providing Form 4 Type 2 and Type 6 internal segregation. Fully compartmentalized busbar, cabling, and functional unit zones to allow safe maintenance without shutting down the entire facility.

Power Factor Correction Unit Energy Optimization
Target >0.95 PF • Detuned 7% / 189 Hz

Automatic Power Factor Correction (APFC) Enclosures

Multi-stage microprocessor-controlled capacitor banks fitted with series detuning reactors. Prevents harmonic amplification, mitigates reactive power penalties from UK distribution network operators, and lowers I²R distribution losses.

Mechanical HVAC Systems Mechanical Building Services
BMS Integrated • BACnet / Modbus

Commercial Chiller & Air Handling Control Suites

Integrated electrical and mechanical motor control centres (MCC) incorporating variable speed drives (VFD), motorized damper sequencing, differential pressure monitoring, and emergency smoke extract interlocks.

Emergency Backup Generation Critical Power
Tier 3 / Tier 4 • Automatic Transfer

Standby Diesel Generation & Static UPS Systems

Emergency power architecture featuring true on-line double-conversion UPS systems paired with 4-pole automatic transfer switches (ATS). Ensures zero-transfer break electrical resilience for hospitals, data centres, and manufacturing.

Industrial Automation Control Automation & SCADA
IEC 61131 • Profinet / Ethernet IP

Industrial PLC Control Panels & Telemetry Outstations

IP66-rated stainless steel and mild steel control panels housing programmable logic controllers, intrinsically safe galvanic isolators, power supplies, and localized HMI touchscreens for process manufacturing.

Lightning Protection System Earthing & Lightning
BS EN 62305 • Class I / II / III

Substation Earthing & Structural Lightning Protection

Engineered copper tape grids, deep-driven earth electrodes, equipotential bonding manifolds, and transient surge diverter coordination to protect commercial structures against high-energy atmospheric strikes.
