Item Details

Respectful with the environment: Chemical gases don’t contain chlorine nor bromine, and in their composition the ODP
is zero, so these gases don’t harm nor destroy the ozone layer.

Safe with properties: Chemical gases are neither electrically conductive nor corrosive for modern components of electrical
systems, and they are clean because their application doesn’t produce remains that may harm the protected systems, so
this fact makes this extinguishing agent to be available for a great number of applications.

Safe with people: In the same way as Halon 1301 and 1211, chemical gases are very safe for areas which are occupied
with the concentration of the official design, and that’s why this product can be used for several risks and in different areas.
EPA and NFPA describe chemical gases as good products for its design and use when it has to be used in spaces with a total flooding.


There are two types of chemical fumes in SISTECOIN


The product HFC-227ea is a colorless, almost odorless and electrically non conductive gas, which has an approximately density of about 5.9 times the air’s density. HFC 227ea is nowadays the most used alternative fire extinguishing agent in the world to halon firefighting equipment. NLE manufactures its total flooding systems with gas, according to the different regulations in force. The extinguishing agent mainly extinguishes fire by chemical means. The HFC-227ea extinguishes fire through the absorption of heat in flames, so when the flame temperature is low enough, the chemical reaction which keeps the combustion working can’t keep continuing and the fire is extinguished. The agent HFC 227ea removes, besides the damages produced by a fire, those damages produced by the fire extinguishing agents, due to its gaseous nature.


Fire extinguishing systems HFC 227ea are designed for discharges up to 10 seconds, and they are used for total flooding applications, because they are very effective in the protection of a wide variety of risks.

HFC 23 is an almost odorless colorless, electrically non-conductive at room temperature (20 ° C), with a density approximately 2.4 times that of air. Extinguishes fires mainly by physical means. Fire extinguished by absorption / extraction of heat in flames. When the flame temperature is low enough, the chemical reaction that maintains the combustion can not continue and the fire is extinguished. HFC 23 attacks fire and extracts on their own sufficient decomposition energy / heat from the flame in a way that flame can not heat more fuel and keep the combustion reaction / fire. This is the same mechanism extinguishing extinguishing agents working in a similar manner (except foam), this process is often described as the "physical reaction" or flame cooling


Designed to discharge 10 second duration, the HFC extinguishing systems 23 are used for total flooding applications resulting highly effective in protecting a range of risks. All kinds of files. Museums, high-value equipment, occupied areas. Rooms switchboards, telecommunications equipment, data centers ...


Any risk to persons created by the discharge of HFC 23 should be considered in the system design. A potential risk can be caused by: The extinguishing agent itself. The combustion products of the fire. Decomposition products of the extinguishing agent resulting from exposure to fire.
