Safety Instrumented System (F&G, ESD, SIS, HIPPS)

Fairtex provides complete Safety Instrumented System (SIS) solutions designed to protect critical operations and ensure safety across industrial processes. An SIS integrates sensors, logic solvers, and final elements to perform defined safety functions that meet required Safety Integrity Levels (SIL). Our solutions comply with international safety standards and are engineered for reliability, accuracy, and long-term performance.

Our services for SIS include:

• Lifecycle Management: End-to-end management from initial design through operation and decommissioning, ensuring continuous safety and compliance throughout the system lifecycle.


• Reliability and Availability Studies: Detailed assessments to evaluate system performance, improve reliability, and minimize downtime.


• SIL Verifications: Safety Integrity Level assessments to confirm that systems can perform required safety functions under defined conditions.


• FAT and SAT Testing and Certification: Factory Acceptance Testing and Site Acceptance Testing to validate system functionality and secure required certifications.

Our SIS expertise covers a wide range of applications, including:

• Programmable Electronic System (PES)


• High Integrity Pressure Protection System (HIPPS)


• Emergency Shutdown System (ESD)


• Fire and Gas Detection (F and G)


• Leak Detection Systems (LDS)

All SIS solutions are designed and implemented by qualified and certified functional safety engineers, recognized by TUV Rheinland or TUV Sud, and developed in accordance with IEC 61508 and IEC 61511. This ensures your systems meet the highest global standards for safety and operational integrity.
