Active Floating Roof Tank Monitoring System
The GroundGuardian® active floating roof tank monitoring system, developed by ALLTEC, alerts you to resistive changes in your roof-to-shell bond, maintaining a safe work environment and reducing risk.
Uses patented, innovative active monitoring technology to detect any change in electrical bond resistance between a floating roof and the storage tank’s grounding system
GroundGuardian® continuously monitors the established ground loop for dangerous deviations–commonly caused by corrosion, wax accumulation, or breakage–in the bond resistance between the floating roof and the external floating roof tank (EFRT)’s grounding shell
Lightning is a constant danger to oil and gas facilities. Rim-seal fires are the most common type of fires for floating roof tanks, especially external floating roof tanks. Lightning can cause fires by generating incendiary sparks in any combustible vapor/air mixture present.
