Fire Fighting


TUNGUS is a new generation of impulse ( very fast acting ) dry powder modules for automatic fire suppression systems.

TUNGUS, modules are non pressurized vessels that can be fitted in any application. They are light weight and easy to install and transport, with no pipe work required, and in normal applications are maintenance free for 10 years.

TUNGUS, modules are the most cost effective powder-type automatic fire extinguisher available on the market. TUNGUS modules are hermetically sealed thus preventing any contamination, by dust or water for the ISTO-1 extinguishing dry powder contained inside the unit.

TUNGUS, modules are activated electrically from a conventional fire panel, from thermal or optical sensors or even manually when it is attached to the modules.

When activated during a fire situation, there is a chemical reaction within the Cold Gas Generator, transforming the solid chemical into Cold Gas, which creates a positive pressure inside the module.

The discharge diaphragm then expands, ruptures and a powerful fire-extinguishing powder jet is ejected into the fire zone putting out the fire rapidly and effectively in less than 1 second.

The dry powder expelled from the TUNGUS module attacks the fire in a combination of two fire extinguishing mechanisms.

Chemically : By removing the fire propagating “chain carriers”

Physically : ( via four processes ). 1- By removing heat via endothermic processes of powder particle heat absorption, particle evaporation and decomposition. 2- Via the dilution of the flame zone with a powder cloud and its subsequent decomposition products. 3- There is a creation of physical fire barriers in the fire zone. 4- Via the creation of a “fire blanket” on the surface of the burning materials.


High extinguishing performance,

Operating within 4 to 8 seconds after detection of fire Powder delivery in less than 1 second after operation Instantaneous extinguishment of fire Protect surface areas up to 80 m2, volumes up to 240 m3 and can be fixed at a height up to 16 mt


No toxic ingredients No ozone depletion No pressure cylinders


Used for Class A, B, C, E fires ( involving electrical energized equipment ) Can be used for total flooding & local applications Can be installed in almost any industrial or residential risk area Wide temperature operating range ( -60 to + 90 C ) The TUNGUS modules are rechargeable

Cost savings,

High extinguishing efficiency Low powder consumption Simple installation Minimal maintenance


10 years Standard lifetime. Modules do not require special maintenance. Monthly visual observation for parts damage. Supervision of the electrical circuitry integrity for electrically operated modules. Following system discharge the area should be cleaned by a non-wet method of dry-wiping, brushing off or vacuuming

Health & Safety,

TUNGUS modules are non-pressurized – non explosive if heated and it is not leaking. TUNGUS modules use ISTO-1 powder ( Mono Ammonium Phosphate based ). ISTO-1 Powder is non-abrasive, chemically inert, non aggressive and non-toxic. ISTO-1 Powder is environmentally friendly, discharged powder residue could be added to the industrial organic fertilizers.
