The HEN Nozzles TURBO BPI is A Revolutionary Advancement, Disassociating Nozzle Pressure from Back Pressure. We have been working on this for a while, get 160gpm@50psi a 60lbs Nozzle Reaction and a 75psi hose Back Pressure, now that sounds like heaven, because it is: Stay up to date on what's now possible, from rig to nozzle, and pattern to seat. HEN is Building the Most Advance & Balanced Handline Attack Package Systems in the World. Back Pressure vs Nozzle Reaction GPM & Pattern Types. A New Trifecta is Now Possible From Pump Operator to Back -up to Nozzles. TURBO Charge All 1.75-inch Handlines with 50psi Nozzles Pressure The Turbo between 150 to 185 gpm, increases Back Pressure an additional 25 to 30psi in the handline stretch from Rig to Nozzles on top of the 50psi Nozzle Pressure in both Flowing and non-Flowing Conditions. Boost 1.75-inch hose performance when using a 50psi NP with impressive benefits in all essential metrics from Higher Pressure Hose to Premium Low-Pressure hose design. Streamline essential members tasks in handline fire stream development on the fire ground, while enhancing suppression and safety: Pump Operator: 1) Higher Initial PDP = Less Kinks On-Charge 2) Simplifies all Transfers to Positive Pressure Source (Tank to Hydrant Transfer & Booster Back-up) 3) No to Less Gating Discharges 4) Governor Functions as Designed when Net Pump Pressure Back-up(s): 1) Entire Stretch Possesses a Back Pressure Enhancement from Rig to Nozzle 2) Appropriately Rigid Line is easier to Feed and Push on Advance 3) Appropriately Rigid Line is easier to Pull on Advance 4) 75psi BP = Less Kink Formation in the IDLH and Outside Nozzles: 1) Achieve proper NP quicker upon call for Water, more Mechanical Force Knocking Dry Kinks Out 2) Reduces to Eliminates Hose and Nozzle Whip Issues 3) Ensures an Arm Length Nozzle Bite, Improving Water Mapping with Less Arm Movement 4) Low reaction force 50psi Nozzle Pressure remains intact.
