In most cases, wildfires develop following prolonged periods of drought and extreme heat in areas which are often inaccessible. They present a special challenge for fire-fighters, as water is regularly in short supply at such locations. Use of wetting agents increases the wetting properties of firewater significantly, contributing to fast, lasting extinguishing results.
is a fire water additive which lowers the surface tension of water and reduces interface tension between water and solid material surfaces. UltraWet® wetting agent does not form water droplets, due to the low surface tension; instead it forms a thin aqueous film on solid materials, which spreads evenly across their surfaces, displacing air bubbles. This enables extinguishing water to penetrate burning materials, e.g. wood, paper, textiles etc. (fire class A), or not easily wetted surfaces, increasing its cooling properties.
Primary use: Municipal fire services, wood/paper industry, recycling industry
Main application: Ember forming materials (fire class A), wildfires
Installations and equipment: Hollow spray nozzles, jet pipes, spray nozzles, water sprinkler or deluge systems, water monitors
UltraWet® is fluorine-free, physiologically harmless and fully biodegradable.
comprises our range of synthetic detergent foam concentrates, which are designed for generating low, medium and high-expansion foam. Interface-active ingredients, foam stabilisers and antifreeze characterise the composition of these powerful, reliable and fluorine-free foam concentrates.
Primary use: Municipal fire services, power stations, industry, plastics industry, recycling plants, maritime, aviation, mining
Main application: non-polar hydrocarbons (fire class B) and solvents, plastics, recyclables, tyres, solid material fires (fire class A).
Installations and equipment: Hollow stram nozzles, low-expansion foam installations, low-expansion foam monitors, low-expansion foam branch pipes, medium-expansion foam branch pipes, high-expansion foam generators, CAFS
All synthetic detergent foam concentrates are fluorine-free, physiologically safe when used as intended, and 100% biodegradable.
STHAMEX®-class Ais a new, refined, highly concentrated foam agent based on foam-forming active ingredients, which are specially designed for extinguishing solid fuel fires (fire class A), as well as for use with compressed air foam system (CAFS). Upwards from 0.1% proportioning rate, STHAMEX® -class A is suitable for use as a wetting agent and, upwards from 0.3%, for CAFS applications. For extinguishing liquid fires (fire class B), the induction rate is 0.5%.STHAMEX®-class A Classicis a highly concentrated foam agent based on fully biodegradable surfactant compounds, developed especially for use on class A fires. STHAMEX® -class A classic is designed in particular for extinguishing ember forming solid material fires in combination with CAFS. The proportioning rate for extinguishing liquid fires (fire class B) is 1%.
Primary use: Municipal fire brigades, industry, recycling industry, waste treatment plants
Main application: Solid material fires, wildfires, non-polar hydrocarbons and solvents, plastics, recyclables
Installations and equipment: CAFS, Hollow stream nozzles, medium-expansion foam branchpipes, low-expansion foam branchpipes, foam / water monitors, foam / water branchpipes
All class-A foam concentrates are fluorine-free, physiologically safe when used as intended, and readily 100% biodegradable.
