HYDROCORE APPROVALS

As a manufacturer of safety critical fire suppression systems, Hydrocore place great importance on obtaining recognised third party approvals and endorsements in order to demonstrate the integrity of their products. On this page we list our current approvals – please contact us if you wish to know more about the fire tests and certifications.

FM APPROVAL: Combustion Turbines and Machinery in Enclosures (up to 260m³)

These areas include enclosures with machinery such as internal combustion engines (excluding engine test cells), oil pumps, oil tanks, fuel filters, generators, transformer vaults, gear boxes, drive shafts, lubrication skids, diesel engine driven generators, and other similar equipment using liquid hydrocarbon fuel and/or hydraulic, heat transfer, and lubrication fluids; enclosures with incidental use or storage of hydrocarbon ignitable liquids (also known as flammable liquids) of not more than two 55 gal (208 L) drums.
Open nozzles manufactured from stainless steel are used in dry-pipe system for the protection of machinery spaces, as part of a total flooding system.
Total Flooding systems use open nozzles (they have no fusible element) spaced throughout a compartment. In this dry pipe system, the water is only contained in the pipework prior to the section valve, until automatically released by a signal from the FDS (Fire Detection System) or manual activation.
The nozzle discharges water at 12.5l/min at normal working pressure, nozzle k-factor of k1.25. Each micro nozzle has multiple micro nozzles fitted on to the nozzle body and each micro nozzle has an integral filter.
Hazards are offered water mist protection for a minimum of twice the longest time to extinguish the test fires, the time to shut down the process equipment or 10 minutes whichever is greater.

FM Certificate of Compliance

All Hydrocore systems are designed, manufactured and tested to NFPA750.
FM Approval 3055962
Hazards are offered water mist protection for a minimum of twice the longest time to extinguish the test fires, the time to shut down the process equipment or 10 minutes whichever is greater.

FM Certificate of Compliance

FM Approval 3059867.

FM APPROVAL: Local Applications

Open nozzle system ensures quick cooling and suppression. This system can be used in conjunction with a total flooding system. Local application systems use open nozzles (they have no fusible element) spaced above or around an object to be protected.
In this dry pipe system, the water is only contained in the pipework prior to the section valve, until automatically released by a signal from the FDS (Fire Detection System) or manual activation.
The nozzle discharges water at 20l/min at normal working pressure, nozzle k-factor of k2.0. Each micro nozzle has multiple micro nozzles fitted on to the nozzle body and each micro nozzle has an integral filter.
All Hydrocore systems are designed and manufactured and tested to NFPA750.

Fire tested closed nozzles for FM Hazard Category 1 (HC-1)

Typical occupancies within the scope of FM HC-1 are offices, banks, restaurant seating areas, apartments, hospitals, hotel rooms, schools, universities and so on.
Closed (bulb) nozzles made from stainless steel are used in wet-pipe systems for the protection of Light Hazard Occupancies, an occupancy where the quantity and/or combustibility of contents is low and fires with relatively low rates of heat release are expected.
Nozzle k-factor is k3.5 and the nozzle discharges water at 35.0l/min at normal working pressure. Each micro nozzle has multiple micro nozzles fitted on to the nozzle body and each micro nozzle has an integral filter.
Closed nozzles having a heat sensitive frangible bulb which ruptures at a set temperature and offers a targeted response in the zone of fire and are used for the protection of light hazard occupancies.
Section valves used are in a Normally Open ‘NO’ position and the pipework contains water up to the closed nozzles. The system is pressurised up to 10bar during the stand by mode and the system pressures increases during a fire activation to more than 100bar.

Road tunnel: 150MW 3rd party witnessed test

Road tunnels usually have substantially large fire loads as compared to other fire scenarios. Typical fire loads could be in the range of 50MW to 100MW+.
A 150MW Oil Pool Fire Test was carried out at the test facilities in Shanghai, China. Experts from TÜV Rhineland were invited to witness the test and to evaluate the performance and effectiveness of the water mist system.
The test tunnel measures 100m long and was sectioned to replicate a real-life system activation.
The aim was to extinguish the oil pool fire under a natural ventilation scenario with a pre-burn time that allowed the temperature to rise up to 1000°C before the water mist system was activated.
Stainless steel open nozzles with a k-factor of 2.0 were used to suppress the fire.
System is a dry pipe system with the water being contained up to the section valve.
TÜV Report No. 154249962.

CCCF Certification

Hydrocore holds CCCF (China Certification Centre for Fire Safety Products) certification which allows the export of High Pressure Water Mist systems to China for use in a wide range of applications, including high rise buildings and public transport systems, where we have a number of active installations already.
