W 6 WNA F-500

F-500 is a tried-and-tested extinguishing water additive, which, thanks to its unique characteristics, shows particularly good extinguishing effects. The extinguishant is fluorine-free but is nonetheless approved for fires of classes A. The main applications for the F-500 fire extinguisher are fires of solid materials, in particular plastics (including SLCs - small load carriers), rubber, batteries and photovoltaic systems as well as fires in warehouses, manufacturing facilities and workshops.

• Fluorine-free extinguishant

• Reduction of surface tension improves extinguishing effect
  [wetting agent effect]

• Increase of surface activity increases depth of penetration into the flammable material

• Fast heat reduction

• Encapsulation of fuels and flammable gases

• Environmentally friendly and easy-to-service F-500 cartridges extend the life of the fire extinguishant in the fire extinguishers

• The extinguisher W 6 WNA F-500 combines water mist technology with the advantages of the F-500 additive

• No sedimentation and incrustation of narrow cross-sections

• Minute water droplets between 20 and 100 microns form a mist with a considerably increased reaction surface

• This eliminates an enormous amount of thermal energy from the fire (approx. 2.5 MJ per litre) and noticeably reduces the radiated heat

• Water mist offers greater safety when sprayed onto electrical systems, up to 1000 V at minimal 1 metre distance according to EN3

• Secondary damage caused by extinguishant exposure (cleaning costs, damage of equipment/inventory, vandalism) are extremely low, since water is only used in small quantities

• No obstruction of visibility when extinguishing

• Long spraying times - beneficial for inexperienced users

• Minimum consequential costs of renewing and disposing fire extinguishants
