Use a HEN Turbo To Create a 165gpm@50psiNP@75psiBP Nozzles From a 200gpm@100psi Adjustable Nozzle

In your existing hose fleet, move rapidly to a GPM Focused Low Reaction Force Small Attack Package, plus Create a Low Pressure 50psi Nozzle with a 75psi Back Pressure from an Existing Nozzle. It is now universally accepted in north America, that small attack package Handline Fire Streams should by GPM focused with low nozzle reaction. This means around 150-185gpm at 40-50psi NP with 50 to 70lbs nozzle reaction range. This is also reflected in NFPA 1710, which states the first two handlines at a dwelling fire shall flow a combined 300gpm. Even though one can technically be 100gpm and the other 200gpm, it is clear that the intent is to have two 150gpm minimum lines established. I prefer 150-160gpm at 40-50psi NP with 50 to 60lbs nozzle reaction, leading to a better chance of full open bale operations and better water placement potential. One of the major issues with low nozzle pressure is that there is not enough force acting to stiffen the hose-lay from rig to nozzle. Nozzle Pressure is also Back Pressure, so the last 36 inches of hose often whips during flow and stream direction. This occurs in both medium duty 75psi Back Pressure (BP) hose design and in light duty 100psi BP hose design. Even with a good low-pressure hose designed for 50psi NP and reaction forces up to 70lbs, nozzle whip can still occur. This can happen because of accidental over pumping conditions or when the nozzle is heavy or extended from the nozzle firefighter’s body a full arm’s length to increase water mapping and extinguishment potential. Creating a small attack package system that is pumped to 75psi back pressure while maintaining a 45- 50psi NP, thus still ensuring around 60 lbs nozzle reaction and 160-175gpm leads to advantages for the pump operator, back up positions and nozzle position. It sounds too good to be true, but is it? Pump Operator, Position: • Higher Initial PDP = Less Kinking Upon Charging • Simplifies Transfers to Positive Pressure Sources (Hydrant, Change Over) • Reduces or Eliminates Gating of Discharges for Low Pressure Small Handline Ops • Reduces or Eliminates Light Reading Gauge Error Based on Velocity / Turbulence at Pressure Pick-up • Governor Functions as Designed More Often as Net Pump Pressure Less Than Discharge Pressure Back-up(S), Positions: • Pressure Enhancement from Rig to Nozzle both Residual and Static • Rigid Line is Easier to Feed and Push • Rigid Line is Easier to Pull on Advance • Less Kink Risk Formation in the IDLH & Outside Nozzle, Position: • Faster Correct Nozzle Pressure Upon Calling for Water, Higher Forces Knocking Dry Lay Out Kinks Free • Reduces or Eliminates whipping in the last critical 36 inches due to hose construction, reaction force or nozzle weight. • Better Hose Handling in the last 36 inches for Improved Water Mapping • Allows for Low Rection Force 50psi Nozzle Pressures, but Creates a Hose Enhancing 75psi Back Pressure • Absorb a large Portion of Accidental Over Pumping during Hydrant Change Over There are 100 Turbo BPI in this design range in field use for the last two months and they have been universally reviewed, as it does exactly what it sets out to do advance the performance of the GPM focused low reaction force handline attack package. Imagine eliminating your current kinking issues on the fire ground by 50% if you’re already in 50psi NP, easier pumping & hydrant transfer, get water faster to the nozzle, stiffer easier line to advance, greater resistance to nozzle whip. The Turbo allows a rapid move to a low-pressure attack package with an existing hose spec, and then through attrition buying better spec ’ed low pressure hose. Only to achieve better and better performance. The HEN Turbo makes all of this possible!
