Continuous Leak Detection for Fuels, Cryogenic and Hazardous Liquids
SOVATZOGLOU S.A. has established a technical cooperation with Permalert, a globally recognized manufacturer of continuous leak detection systems for fuel lines, cryogenic liquids and other hazardous fluids.
This cooperation supports projects where early leak detection is a critical safety requirement, both for fire prevention and for minimizing environmental impact and operational risk in industrial and critical infrastructure facilities.
Role of Leak Detection in Mechanical Design
Leak detection is not treated as an auxiliary or secondary system. It is an active risk mitigation measure, particularly in installations involving:
- Fuel distribution networks
- Double-wall piping systems
- Cryogenic liquid lines
- Underground or concealed pipe routes
- Facilities with increased safety and insurance requirements
Integrating leak detection at the design stage enables early intervention before a leak escalates into a fire, explosion, or environmental incident.
Permalert System Architecture
Permalert systems are fully engineered monitoring systems consisting of:
- Sensing cables or probes installed along piping routes or within defined zones
- Monitoring and control units
- Leak location and identification capability
- Interfaces for alarms or connection to the facility monitoring system
System operation is based on the immediate detection of liquid presence or vapor conditions, allowing accurate identification of the leak location.
Continuous Monitoring and Early Warning
Unlike periodic inspections or visual checks, Permalert systems provide continuous, real-time monitoring of protected piping and spaces.
In the event of a leak:
- an alarm is triggered immediately,
- the affected zone or location is identified,
- corrective action can be taken without delay.
Early warning significantly reduces:
- The risk of fire or explosion
- Uncontrolled release of fuels or hazardous liquids
- Repair costs and operational downtime
Typical Applications
Within SOVATZOGLOU S.A. projects, Permalert systems are typically applied in:
- Fuel supply and transfer networks
- Double-wall piping installations
- Cryogenic liquid systems (LN₂, LOX, CO₂, etc.)
- Data centers with fuel lines routed below raised floors
- Underground pits, trenches and technical voids
- Industrial facilities handling hazardous liquids
System selection is based on fluid type, installation layout, and project-specific requirements.
Integration with Safety and Fire Protection Systems
Permalert leak detection systems are integrated into the overall safety concept of the facility and coordinated with:
- Fuel and hazardous fluid systems
- Fire detection and fire suppression systems
- Operational and maintenance procedures
This approach ensures leak detection operates preventively, before a fire or major incident occurs.
Standards, Compliance and Insurance Requirements
Leak detection systems are frequently required by:
- EPC contractors and consultants
- Insurance providers
- Regulatory and inspection authorities
Permalert systems support documented compliance with these requirements by providing reliable and verifiable leak detection for critical installations.
Role of SOVATZOGLOU S.A.
SOVATZOGLOU S.A. is responsible for:
- Technical assessment of leak detection requirements
- Delection and integration of the appropriate Permalert system
- Mechanical installation within the project scope
- Testing and handover and commissioning
- Technical documentation and ongoing support
Permalert systems are implemented as part of real mechanical projects, within a comprehensive safety and risk management framework.
Summary
The cooperation with Permalert enables SOVATZOGLOU S.A. to integrate continuous leak detection systems into projects with increased safety requirements, strengthening fire prevention, environmental protection, and long-term operational reliability.
