 Floating Roof Tank (Rim Seal) Fire Protection

Grishma's TANK GUARD - Floating Roof Tank protection is a fully automatic detection cum extinguishing system. The system is designed and manufactured for extremely fast detection and extinction of any type of rim seal fires as per the International Safety Standards.

Linear heat detectors are based on the physical principle that volume and pressure of a gas changes whenever its temperature changes. The detectors senses rate of rise of temperature and maximum fixed temperature in terms of pressure and trigger an alarm by combine signals of both parameters. The change in pressure is instantly registered by microprocessor electronic pressure sensor connected to the extremity of the tube. A Stainless Steel / Copper sensor tube monitors surrounding temperature over a distance of approx. 100 m. of rim seal area. Baby fire is detected within few seconds, which trigger an alarm and actuates the extinguishing system. The foam module is charged with pre-mixed foam solution as per the International Safety Standards. Foam Discharge Manifold with Spray Nozzles are evenly spaced along the Rim Seal and are designed to discharge required Foam solution to control the fire completely.

To exclude any type of faulty measurements, an inbuilt test motor is provided in the evaluation unit, which checks the healthiness of the sensor tube at regular intervals. If the pressure rise actually measured does not correspond to the programmed measured value, a malfunction indication is displayed. The system is user-friendly, immune to electrical, thermal and mechanical interference.

The system can also be equipped with Dry Chemical Powder as extinguishing agent as per the hazards application. DCP Discharge Manifold with spray Nozzles are evenly spaced along the rim seal and are designed to discharge DCP to control the fire completely.
