Hydrophore Systems

The Firenor hydrophore system is a safety system designed to prevent pressure surges in the firewater distribution piping that occur when a deluge system or any other water consuming systems release water before fire water pumps are up and running. When a high flow firewater consumer starts before the fire water pumps, water is drained from the highest points of the ring main. This drain results in a vacuum in the upper levels of the ring main. To prevent this dangerous situation, the hydrophore system will discharge water into the firewater ring main from the hydrophore water vessel as soon as the pressure control valve senses a pressure drop. This pressurizes the pipes and practically preventing the risk of a pressure surge by preventing the vacuum from ever forming.

SYSTEM DESIGN

The water vessel for the Firenor hydrophore system has a standard water capacity that is capable of functioning for up to 30 seconds, long enough to prevent pressure surges in standard fire protection systems. Pressure in the water vessel are maintained by an air cylinder rack with a booster pump that refills after each use. The release and reset mechanisms for all parts of the hydrophore system are fully automatic. Furthermore, the entire system also includes all valves and instrumentation necessary for standard operation, maintenance, and testing. All design parameters of the Firenor hydrophore system can be customized as needed in order to meet specific project requirements.

VERIFICATION

Every system can be customized, upon request, for compliance with applicable rules, regulations and project specific requirements as well as standard such as CE, FM, UL, ASME, DIN, DNV, BV, NMD, IMO, NFPA, Norsok. Full documentation for any tailor-made products are available and include all necessary certifications, third party verifications such as DNV/GL, BV, ABS, etc., and full scale test reports, if required.
