STRUCTURAL FIRES
The power of HEN Nozzle® technology for structural fire attack
Structural Fires Today
MODERN FIRES BURN FASTER
Today's fires burn faster than ever before. This rapid progression is driven by several factors, including the synthetic materials found in modern furnishings, interior finishes, and the growing prevalence of lithium-ion batteries in everyday items. Used in consumer electronics, power tools, micromobility devices, and electric vehicles, lithium-ion batteries can reach thermal runaway and explode in as little as 15 seconds after the first sign of smoke.
Structural Fires
WHAT'S NEEDED
Surface Cooling, Coverage, & Gas Cooling
Big Droplets
Surface cooling
Low coverage
Low gas cooling
Small Droplets
Low surface cooling
Area coverage
Gas cooling
Big Droplets + Spread
Surface cooling
Wide area coverage
Gas cooling
Traditional smoothbore nozzles produce big droplets which are excellent at surface penetration but lack coverage and have low gas cooling abilities. Fog nozzles produce large coverage, but the small droplets evaporate quickly, unable to penetrate to cool surfaces. What's needed is the penetration power that come from big droplets paired with a wide spread.
Performance
HEN® SOLVES THIS WITH THE BLADE® NOZZLE
HEN's BLADE® is the only nozzle that provides large penetrating water droplets resulting in surface cooling and gas cooling. The BLADE® nozzle combines the surface penetration of smoothbore tip nozzles with the wide coverage of combination fog nozzles. The unique in-line blade pattern ensures rapid knockdown and creates survivable space, making them an invaluable tool in structural firefighting.
