WAVE floor nozzle system – water tunnel short Floor nozzle system consisting of at least 4 arc-shaped gentle volume jets adjustable in all directions, which together form a water tunnel; design, documentation and scope of delivery mandatory according to EN 13451. Materials, design: nozzle elements and built-in parts, fastening systems at least made of stainless steel 1.4571, the surface of the nozzle elements must be modeled and designed for a sensor life with an affinity for water; flat nozzles or built-in parts with a horizontally flat finish do not meet this requirement; nozzle elements with vandalism-proof installation aid for screwing into the built-in parts Dimensions: Recessed part including nozzle element approx. 220 mm high, installation at ground level, length approx. 1500 mm Water effect(s): 4 curved jets lined up as gentle volume jets at even intervals. The alignment of the beams can be manually adjusted on site in all directions and in the angle of inclination up to 25 degrees (from vertical). Ground anchor system: Nozzle and ground anchor form a functional unit. Only uniform, identical floor anchor systems for floor jets may be used within a water feature area. Therefore, it is mandatory to install the floor anchors of the manufacturer of the water attraction, with the option of being able to install different floor nozzles (e.g. water mist, water calyxes, water tails, etc.) on the floor anchors at floor level instead of the advertised nozzle. (floor anchor in separate position) Hydraulic requirements: The flow rates are to be optimized with regard to player life and water flow; max. permissible flow rate 11 – 22 l/min; The water effects of the above min. and max. permissible water flow rates shall be documented by video recordings. It is mandatory that the required properties be substantiated by means of data sheets with photos/renderings, which must be enclosed with the bid upon submission in order to be evaluated.
