INERGENA� Official Distributor


Up until the 1970s the most common gas-based extinguishing agent in deluge fire protection systems was carbon dioxide (CO2). CO2 presents a serious danger for human life, due to it being toxic in concentrations above 10%, and one needs concentrations above 30 % to put out a fire. With the introduction of Halons, and specifically of Halon 1301, the use of CO2 practically stopped, with the exception of some very specific applications.

Unfortunately, in the last few years it has been demonstrated that Halons greatly contribute to the destruction of the ozone layer.

With the purpose of protecting said ozone layer by controlling the production of substances that degrade it, the Montreal Protocol entered into force on January 1st, 1989, effectively prohibiting the use of Halons in extinguishing systems, with the exception of some very specific applications. This prohibition has motivated the search for alternative extinguishing agents.

The use of alternative gases like industrial fluorinated gases (HFCa��s, PFCa��s and SF6a��s) goes against the directives established in the Kyoto Protocol regarding climate change, which stipulates that there must be a reduction in the emission of these gases, which are responsible for the greenhouse effect or global warming.

The INERGENA� gas has become a 100% ecological alternative compatible with human life, for extinguishing systems based in gaseous agents.

  • It does no harm to the ozone layer.
  • It does not contribute to global warming.
  • It has an atmospheric lifetime of zero.

INERGENA�A�is a mixture of gases present in the air we breathe.

INERGENA�A�is a corrosive gas, non-toxic, that aids in the combustion process.

INERGENA� gives the brain the same ratio of oxygen present in normal air, without losing its effectiveness as an extinguishing agent.

Bearing in mind that INERGENA� is a clean agent that doesna��t damage objects and is safe for persons (it allows breathing), it is particularly adequate for the protection of areas where fire could cause great economic or human losses, such as:

  • Computer rooms
  • Transformer rooms
  • Archives
  • Telecommunications centrals
  • Labs

Maintenance of fire protection systems and equipment.

Fire protection facilities are of a vital importance for the security and protection of the public, as well as of material assets.
The optimal use of the facilities is obtainable with the continuous and adequate maintenance performed by the Client, which is done according to the inspections established by all the different regulations.
SPG Fire & Security, recommends and offers the performance of these periodic inspections by specialized personnel, for making sure that the maintenance is done properly, and for detecting possible flaws and problems that might go unnoticed to the untrained eye.

Own System Fire in Spheres


Containing LPGa��s in spherical vessels implies high fire hazard, either by a leak caused by the vessel itself, either through leaks and / or fires at short distances to the vessel whose influence can generate a catastrophic incident for structural failure of the affected sphere.

For that reason those vessels are usually provided with active protection measures against fire that basically consist in cooling by water according to international standards so that, facing a dangerous increase in temperature of the walls and its structural elements, the refrigeration is appropriate for the fire exposure not to affect its characteristics, thus avoiding disastrous accidents.

Sistema de ProtecciA?n de EspecA�fica de Esferas S.P.G.

Active protection system against fire for spherical vessels was designed by Spanish engineer Salvador PallarA�s in the 80a��s (ETSIIB, Spain), fire protection specialist with over 35 years experience, and has been successfully tested and proven effective. Since then, the system is guaranteed by its use for over thirty years with no problems in over 450 spherical vessel installed in several countries. S.P.G. Fire & Security S.L. as system installation company has every smelting model, application guidelines, and a wide designing and assembling experience. As a result we achieve a compact, easy and safe modular system against fire for spherical vessels used in LPG storage at chemical and petrochemical sites.

Advantages of the S.P.G. protection system for spherical vessels.

  • The entire installation is completely removable.
  • Completely prefabricated in our workshop.
  • The system is assembled once the vessel is completely finished, thus avoiding to interfere with painting or any other work.
  • Mounting the protection can be done after painting and / or thermally insulating the sphere without special scaffolding, due to the use of inertia retaining elements placed on the top platform where the assembly operators are located
Benefits for End Customer
  • Thanks of being FULLY REMOVABLE, to perform periodic maintenance to the spheres.
  • The installation against fire is disassembled, checked, cleaned, stored, and once made the maintenance of the area, reassemble is easily accomplished with significant cost savings to the end customer.
  • The possibility of acting only over the 50% of the surface of the sphere significantly reduces overall water needs for vessel groups in the adjoining areas, which in turn reduces the problems of insufficient capacity of existing pumping systems in plants when fire protection is extended.
