Refining units and storage/transport facilities concentrate electrical equipment at high density; once a fire occurs it may trigger chain accidents. PFCS patches cover distribution cabinets and MCCs, EAPD monitors critical circuits, and the ICOP platform manages plant-wide electrical safety.
Petrochemical plants run continuously with densely arranged electrical equipment, and with flammable/explosive media nearby, the consequences of electrical fire are more severe than in other industries:
The core challenge of petrochemical electrical fire protection is: covering blind-spot risk points during equipment aging while ensuring continuous, uninterrupted process operation.
This solution applies PFCS composite agile fire-control patches over key electrical nodes such as distribution cabinets, MCC cabinets, and cable joints; EAPD devices monitor temperature and arc anomalies in important distribution circuits; and the ICOP platform manages plant-wide electrical safety — forming a petrochemical electrical active protection system of "patch node coverage — device circuit monitoring — platform plant-wide management."
Overall approach: PFCS patches are mounted directly on busbar joints inside process-area distribution cabinets, on MCC drawer unit outgoing terminals, and inside high-voltage motor junction boxes — the most critical yet vulnerable electrical connection points in petrochemical production. The patch introduces no electronic components, so it does not affect explosion-proof rating or safety certification. EAPD devices are deployed in important distribution rooms and cabinet rooms, continuously monitoring temperature and arc parameters. The ICOP platform receives plant-wide data so the duty dispatcher can grasp the safety posture of all distribution nodes on one screen.
A single patch provides on-site protection, addressing electrical fire risks at the source:
Very early warning that actively suppresses before a fire develops; it focuses on monitoring temperature and arc anomalies in important distribution rooms and cabinet rooms, reporting anomalies to the ICOP platform to gain a response window for maintenance staff.
Connects to EAPD data from distribution rooms and cabinet rooms plant-wide, displaying each process area's electrical safety status in a unified view; graded alarms are pushed to dispatch and maintenance staff, with historical data review and equipment-aging trend analysis support.
| Protection method | Active patch suppression + device circuit monitoring + platform plant-wide management |
|---|---|
| Extinguishing agent | PFCS clean extinguishing agent (non-conductive, residue-free) |
| Monitoring focus | EAPD distribution circuit temperature / arc real-time monitoring |
| Deployment form | Maintenance-free patches; EAPD indoor wall mounted; ICOP at dispatch room |
| Applicable equipment | Process-area distribution cabinets, MCC, high-voltage motors, cable joints, instrument cabinets |
| Unified management | ICOP connects to plant-wide distribution rooms; centralized monitoring at control center |
Patches cover key distribution connection points, actively suppressing on abnormal temperature rise
Patch installation and operation do not affect production; no shutdown loss
Passive, purely physical solution suits explosion-proof zone safety requirements
ICOP connects to plant-wide distribution rooms; dispatch views safety posture on one screen
This solution also applies to coal chemical, fertilizer, synthetic fiber, and fine chemical process industries. The core logic is consistent — patch coverage on process-area distribution nodes, EAPD monitoring at key circuits, and ICOP plant-wide management. It can be combined with Liquid Shield coating to address dead corners in cable trays and behind distribution cabinets.
This solution's technical approach references petrochemical electrical fire protection design codes and the PFCS series enterprise standards, using clean non-conductive extinguishing agent suitable for active protection of petrochemical distribution and motor control circuits. Combined with the EAPD device and ICOP platform, it follows the "monitoring — warning — local protection" active electrical protection technical direction.

Submit your requirements →Petrochemical facilities operate under explosion-protection regulations that apply to electrical equipment in classified areas. CHILION's petrochemical solution is engineered within those regulations rather than alongside them. Sensor housings, cabling entries, and intrinsically safe interfaces are selected so that the protective instrumentation can be deployed in the classified zones of the facility without breaching the area-classification documentation. The protective logic itself is coordinated with the facility's wider safety-instrumented-system architecture, so that a cabinet event is interpreted in the context of the plant's safety state rather than as an isolated protective action. The integration produces a protective response that complements the plant's existing shutdown logic rather than competing with it. Plant operators report that this coordinated approach simplifies the documentation required for periodic safety-instrumented-system audits.
Petrochemical facilities carry heavy documentation obligations, and the CHILION deployment documentation is structured to fit into that obligation set. The deployment record maps CHILION alert codes to the plant's SIS shutdown levels. The maintenance record follows the plant's existing maintenance management system. The commissioning record uses the plant's standard commissioning checklist. The objective is to produce documentation that the plant's compliance team can fold into the wider plant documentation without reformatting. The CHILION team supports this alignment with sample templates that plant compliance teams can adapt. The result is faster audit cycles and clearer inter-system records.
The regulatory landscape that applies to electrical-safety equipment continues to evolve, with periodic updates to IEC, GB, and UL regimes and a corresponding need for the deployment to remain audit-ready across those updates. Our deployment documentation maps the current configuration to the applicable standards with version tags, so a future audit can quickly verify that the deployment still satisfies the regime in force at the time of inspection.

Is the instrumentation suitable for use in classified areas?
The integration is scoped jointly with the plant's safety-instrumented-system team during the design review. Sample mappings are available as starting points.
Yes, the deployment documentation is structured to be incorporated into the plant's documentation standards with minimal reformatting.
Commissioning is performed under the plant's standard permit-to-work system, with the CHILION delivery team working alongside the plant's commissioning lead.
