“Rimsafe” Floating
Roof Tank Rim Seal System is a fully automated system
aimed at detecting of the fire occurring within the rim
seal area owing to reasons like lightening strike, static
electricity, etc and to detect such a fire at the incipient
stage automatically and to deploy the extinguishing agent
instantly on the entire periphery of the rim seal area
and thus to extinguish the fire rapidly.
The Rim Seal System consist
of a highly intelligent microprocessor based Linear Heat
Detector connected with a hollow metallic tube (SS/Copper),
which acts as the heat sensor. The intelligent linear
heat detection evaluation unit works on the principal
of detection of rate of rise in temperature and maximum
pressure. When the user set pre-configured parameters
exceeds, the system determines occurrence of a fire, triggers
audiovisual alarm and actuates the extinguishing system.
The Extinguishing system consists
of foam vessels / modules of suitable capacity designed
as per NFPA/OISD 117/118 standards to meet the extinguishing
requirements and to cover the rim seal area. Pre-mixed
Aqueous Film Forming Foam solution is used as the Extinguishing
Agent. N2 gas is used as an expellant for discharging
of the foam out of the vessels. The Linear Heat Detection
system actuates the foam based extinguishing system.
