Control Systems & BMS Upgrades (CSBU)
Replace obsolete mechanical jackshaft linkages and legacy relay panels with state-of-the-art PLC Burner Management Systems (BMS), parallel positioning micro-modulating actuators, oxygen trim, and SCADA telemetry engineered to Saudi Aramco SAES-J-601 standards.
Transform Legacy Mechanical Controls Into Intelligent, High-Safety Digital Boiler Islands
Legacy single-servo jackshaft control systems suffer from mechanical slop, hysteresis, and imprecise air-fuel ratio modulation, leading to excessive fuel wastage and high carbon emissions. Furthermore, outdated relay-based flame safeguards increase the risk of furnace explosions and trigger frustrating, unexplained nuisance plant shutdowns.
Saudi Boilers Company designs, builds, programs, and commissions complete Control Systems and BMS Retrofits. Featuring dual-redundant SIL-3 PLC controllers, direct-drive stepper servomotors, continuous zirconia O2 trim, 3-element feedwater control, and cyber-secure SCADA telemetry, our solutions ensure uncompromised combustion safety and peak operational efficiency across KSA.
Micro-Modulating Parallel Positioning
Independent optical-encoder servomotors for fuel gas, oil, and combustion air dampers to achieve sub-degree positioning precision and eliminate hysteresis.
SIL-3 Safety PLC Architecture
Fail-safe programmable logic controllers managing automated furnace purge, pilot proving, main flame supervision, and leak-proving interlocks per Aramco SAES-J-601.
Control Systems & BMS Modernization Modules
