‘Attack 750 Hi-Flow Low-Flow HR’ High Rise Fire Nozzle
When tackling high rise building fires the fire crew will connect their hose lines to Dry Riser outlets which are present on every floor of the building. Water pressure on the lower floors is generally maintained allowing for efficient nozzle performance but the firefighter can often suffer from pressure loss on upper floors which can result in poor flow rates to the nozzle and subsequent reduced capabilities in fire suppression leading to a significant increase in risk to the fire crew.
Delta Fire’s design team have worked closely with Manchester Fire & Rescue Services with a view to producing a branch that will retain constant performance at varying flow rates on all levels of a high rise building preventing erratic nozzle performance. The solution to this problem came in the production of a hybrid to the well-respected Delta Attack 750 fire nozzle. Already in use in Brigades and the Marine and Industrial sectors this nozzle was specially adapted to accept new internals that would regulate both high and low flow rates from the rising main.
The new ‘Attack 750 Hi-Flow Lo-Flow HR’ retains all the attributes of the stock 750 such as computer designed stainless steel turbine spinning teeth producing an extremely dense fog pattern, the long range jet capability and the compact design that weighs 30% less than comparable nozzles but with the added benefit of dealing with a wide spectrum of pressure variants.
The contract to supply 75 of these bespoke High Rise Fire Nozzles to the Manchester Fire & Rescue crew increases Delta Fire’s dominance within this field.
Delta’s ability to provide a bespoke design service to their clients is facilitated by a highly experienced team of Industry technicians, in-house 3-D modelling capabilities, on-site cutting edge CNC machining and a dedicated sales and customer services team that ensure deadlines and expectations are met.
