ARGON Gas Fire Extinguishing System

LPG INERT® IG-01 (Argon) is an inert gas naturally presents in the atmosphere, Therefore its
green- house effect is nil and its ozone layer depletion potential is zero.   It is chemically inert,   
non- conductive, colourless, odourless and Ńavourless. Argon is no corrosive and may be used at normal temperatures with   such   materials    as   nickel, steel, stainless steel, copper, brass, bronze and plastics.

LPG INERT® IG-01 extinguishing   systems    are based in the principle of reducing the oxygen concentration    inside    the    protected   hazard. The oxygen concentration is minimized by the application of Argon until it reaches a level where combustion is no longer supported. Each system   is designed   so as to decrease oxygen to a specific   level.  When   discharged, Argon is quickly and uniformly distributed within the enclosure,   achieving design concentration in 60 seconds.  Discharge is through valves fully developed by LPG and approved by the most renowned independent approvals organizations. They offer great Ńexible adaptability for all actuation and release systems currently used in the market, even allowing combinations of several of them. The design of the system protects against accidental   actuation   due to any small leak.

They also allow checking and maintenance of all critical elements   contained   in a fixed extinguishing system, at the time of commissioning and later for system preventive maintenance, thus preventing the risk of accidental discharge.  As a general rule, extinguishing concentration  is  achieved  when  oxygen  contents   in the  air  is  reduced  from  its  usual  level of  20,9% to values lower  than 15%  depending on the combustible products.
LPG INERT® IG-01 is stored in high-pressure cylinders in the form of compressed gas, thus space required for such cylinder storage depends on pressure and capacity. IG-01 fire extinguishing systems are designed for a cylinder filling pressure of 200/300 bar. LPG uses cylinders of 80 lt. and 140 lt. capacity thereby, optimazing in space and costs.
Although the method LPG INERT® IG-01 systems use to extinguish fires is the same as the method used by CO2 (reduction of oxygen concentration within the hazard), IG-01 is safe for use in occupied areas and excellent visibility is maintained during discharge.
LPG INERT® IG-01 is ideal for the protection of archives, museums, libraries and any other hazard including valuable or unique property.  Likewise it is suitable for the protection of computer rooms, telephone exchange equipment and any other electrical installation that may present a fire hazard.
