Emergency Shutdown (ESD) Panel

• Pneumatic ESD panel – for sites with instrument air or gas and no reliable power.
• Hydraulic ESD panel – for wellhead shutdown at hydraulic pressures up to 10,000 psi.
• Electro-hydraulic ESD panel – electric pumps and solenoid valves where power is available and integration with the plant system is needed.
• Hardwired relay ESD panel – simple, fixed logic without software for smaller installations.
• Safety PLC ESD panel – for complex cause-and-effect matrices and SIL-rated functions.
• Single-control or multiple-control outputs – one shutdown action for the whole site, or staged shutdown of separate zones and wells.

• Controlled shutdown – SDVs, blowdown valves and wellhead valves close in the sequence defined by your cause-and-effect matrix.
• Shutdown completes on loss of supply – hydraulic and pneumatic accumulators hold the energy to finish the shutdown.
• Fire detection at the source – fusible loop and fire and gas inputs initiate shutdown automatically.
• Faster diagnosis – first-out indication shows which condition started the trip.
• Confidence in shutdown valves – partial stroke testing confirms valve movement without stopping production.
• Integrated monitoring – status, alarm and trip signals to DCS or SCADA.
• Built for the environment – SS 316L enclosure, Zone 1 or Zone 2 equipment, and NACE MR0175 / ISO 15156 materials where required.

IEC 61511 functional safety when a SIL is specified; API RP 14C / ISO 10418; IEC 60079 hazardous-area equipment.

• Designed in Canada, built in India – engineering from Vaughan, Canada and manufacturing in Chennai, India give you international design quality with competitive pricing and lead times.
• Built to your specification – we engineer to your P&ID, data sheets and company standards, and submit GA drawings and 3D models for approval before fabrication starts.
• Proven in demanding service – our high-pressure Inconel 625 sampling stations have been supplied in series to Saudi Aramco refineries, and our lab, pilot and skid systems are used by national laboratories, universities and industrial R&D teams.
• Traceable quality – PMI, dye-penetrant and hydrostatic testing as specified, EN 10204 3.1 material certificates, and NACE MR0175 / ISO 15156 materials for sour service.
• Witnessed FAT and full documentation – factory acceptance testing with you or your third-party inspector, and a complete documentation dossier with every unit.
• One point of responsibility – engineering, fabrication, testing, installation support, commissioning, operator training and spares from one supplier.
• For this product: logic built to your cause-and-effect matrix in the technology you choose, with accumulators to complete the shutdown on loss of supply.

Engineering to your P&ID, data sheets and company standards; drawings submitted for approval before manufacture; factory acceptance testing (FAT) with client or third-party inspection; export packing and full documentation dossier; installation support, commissioning, SAT and operator training; spares and after-sales support worldwide.
