DOOR FAN TEST
ESSECI S.r.l. offers an instrumentation rental service and performs tests directly with its own qualified technicians. On request, a Test Report signed by a Fire Prevention Expert can also be issued.
WHAT IS A DOOR FAN TEST?
The Door Fan Test (also known as the Seal or Integrity Test) is a particular procedure that checks the permeability or “seal” of a room. In the event of fire, gas extinguishing systems are able to determine whether the protected volume is capable of retaining the discharged gas or not and to maintain an adequate concentration for a certain period of time, referred to as the Soaking Time orHold Time.
WHEN IS THE DOOR FAN TEST NECESSARY?
A Fan Door Test is necessary whenever a gas extinguishing system is designed and installed, as an alternative to a complete gas discharge test that is much more expensive.
The test is required by all the main technical standards such as UNI EN 15004-1, ISO 14520-1, NFPA 2001, UNI 10877-1, UNI 11280.
The result of the Door Fan Test is part of the certification that the installer is required to provide to the customer.
The test is necessary not only in the initial system commissioning and acceptance phase but must be repeated in the event of any change in the integrity of the area due, for example, to wall openings or other changes to the volume. The Door Fan Test is also required in the event of loss of its relative documentation and upon the scheduled system servicing (every ten years).
WHY IS IT IMPORTANT?
The correct functioning of a gas extinguishing system, and thus its effectiveness in the event of an actual fire, depends on the seal of the volume into which it is discharged. A volume that is too permeable will not retain the extinguishing gas long enough, resulting in an increasing risk of fire re-ignition following discharge. The Door Fan Test is also necessary to correctly size the overpressure damper.
Types of fire-fighting systems
Our Aerosol extinguishing systems are efficient, free from environmental impact and competitive on the market due to their swift design, installation and maintenance.
Carbon Dioxide (CO₂) systems are simple, reliable and effective. Being easy to manage and maintain, they offer total safety even in large industrial production spaces.
Our inert gas systems use Argon and Nitrogen which, due to their nature, offer complete safety even on particularly delicate and precious materials.
Dry powder extinguishing systems, in particular with Sodium Bicarbonate, are ideal for extensive sites in the petrochemical industry.
Water Mist extinguishing systems are efficient, having no environmental impact and being non-toxic, offering a high extinguishing power thanks to the elevated pressurisation of the water that is not released as a “deluge” but is sprayed.
In the event of fire, these active safety systems guarantee the escape of any smoke from the safeguarded rooms, produced by the combustion in the areas at risk. With this mode, the SistemOpen90°™ ensures the areas are safe and smoke-free, guaranteeing the area leading to the escape routes is protected.
Designed to suppress and extinguish fires of solid materials, flammable liquid fuels and electrical equipment.
Foam Systems avail of a mixture of water and foam to extinguish fires and are particularly appropriate in the presence of flammable liquids.
For all systems using water as an extinguishing agent, these guarantee that the flow rate is exact so as to ensure perfect efficiency and reliability.
ESSECI S.r.l. offers an instrumentation rental service and performs tests directly with its own qualified technicians. On request, a Test Report signed by a Fire Prevention Expert can also be issued.
In the event of a fire, active safety systems guarantee a higher pressure in the safeguarded premises than in the other environments. In this way, they keep the safeguarded areas constantly free from smoke, creating a protected area leading towards the escape routes.
Our smoke and gas detection systems, with the relative alarm signalling systems and any extinguishing units, guarantee full protection against the risk of fire.
Integrated detection, video monitoring and extinguishing systems with remote control for the open-air storage of various kinds of flammable materials.
