Design and manufacturing of explosion-proof MV/LV switchgear and fault-tolerant automation systems complying with ATEX, IEC 61439, IEC 62271, and SIL-3 safety standards to ensure operational continuity in hazardous environments.
Petrochemical environments demand zero downtime. Electrical failure translates to catastrophic environmental and financial risk.
Challenge: Arc Flash hazards in gas-rich zones and heavy compressor startup surges.
Solution: Metal-Clad switchgear up to 36kV, compliant with IAC AFLR arc-resistant classification (IEC 62271-200), featuring pressure relief flaps and optical arc flash detection relays (< 5ms response).
Challenge: Need for hot-swappable pump feeders and protection against corrosive gases (H2S).
Solution: Modular Form 4b withdrawable units per IEC 61439-2. Silver/Tin-plated busbars for chemical resistance, integrated with intelligent motor protection relays and redundant Modbus TCP/Profinet.
Challenge: Requirement for instantaneous emergency shutdown without false trips.
Solution: SIL-2/SIL-3 compliant architecture using Hot-Standby Redundant PLC systems, full SCADA integration, and intrinsically safe (Ex-i) isolation barriers.
Engineering documentation, FAT reports, and equipment delivery references.
33kV Arc-Resistant Metal-Clad switchgear with redundant Siemens protection relays.
24-module drawout MCC with live thermal and current monitoring.
Fault-tolerant automation system for LPG storage tank safety.
Technical insights regarding compliance, testing, and documentation.
Yes. All AHT Electro switchgear is manufactured based on designs validated by EPIL Type-Tests. We fully facilitate and support Factory Acceptance Tests (FAT) with third-party inspectors from organizations such as SGS, BV, and TÜV, or your internal technical inspection teams.
We utilize heavy silver/tin-plated busbars compliant with ISA 71.04 Class G3. Enclosures are coated with acid-resistant electrostatic paint and marine-grade polyurethane. All PCBs undergo Conformal Coating to protect against atmospheric corrosion and humidity.
Every shipment includes our Comprehensive Technical Dossier: EPLAN P8/Pro Panel As-Built schematics, thermal and short-circuit calculation reports, FAT protocols, relay calibration logs, complete Bill of Materials (BOM), O&M manuals, and our corporate warranty certification.
