Multi nozzles

Optimize precision and efficiency with our cutting-edge nozzle innovations tailored for shallow removal in hydrodemolition operations. Our nozzle configurations either divide the waterjet impact across multiple points, extending the covered area, or employ intersecting jets that cancel each other out at a specific depth, achieving exceptionally precise cuts. Both techniques excel in effective shallow removal.

Divide the power

Discover the versatility of our Aqua Cutter robots, offering multi-nozzle configurations for both single lances and Rotolances. For single lances, the Dual and Triple nozzle heads work perfectly for shallower removals by dispersing the waterjet impact across multiple points, effectively extending the covered area. The Rotolance, equipped with a standard Spraybar, is efficient for cleaning, light removal, and surface preparation. It’s also compatible with both Dual and Triple nozzle heads, as well as the Cross nozzle option, providing precise shallow removal to specified depths with its intersecting water jets.

Features

  • Dual and Triple nozzles

    The Dual and Triple nozzle are designed to work seamlessly with lances, lance extensions, and Rotolances. When paired with an oscillating lance, the Dual or Triple Nozzle effectively divides water jet power into two or three impact points, narrowing the oscillation pattern. This feature proves invaluable for shallower removals where the automatic speeds of the robot may fall short in achieving a smooth cut surface. In terms of rotational hydrodemolition capabilities, the dual and triple nozzle heads also serve as compatible attachments for Rotolances. Recognized as “Hydromilling,” this configuration specializes in shallow removal, typically ranging from 10-50 mm, making it a powerful tool for precision hydrodemolition projects.

    The Dual and Triple Nozzle Heads from Aquajet are ideal for scenarios involving high-powered pumps to remove shallow areas. In contrast to a single nozzle setup, employing these nozzle heads eliminates the need for the robot to move at high speeds for optimal results or reduce pump power. The intentional design of the nozzle heads, being both compact and lightweight, ensures the robot can fully unleash its potential, delivering efficient and precise hydrodemolition in various applications.

     

  • Laminar flow director

    The Dual and Triple Nozzle Heads features our unique LFD® (Laminar Flow Director) concept. The innovative LFD® design effectively eradicates turbulence right before water enters the nozzles, ensuring operational efficiency comparable to using two or three separate lances.

    Traditional setups experience turbulence when the flow of water changes direction or passes through diameter variations, disrupting the water jet’s flow through the orifice and diminishing its effectiveness. The LFD® design mitigates this issue, maintaining a smooth flow and optimizing the water jet’s performance.

  • Dual nozzle

    The Dual Nozzle divides water jet power into two impact points, narrowing the oscillation pattern. Perfect for shallower removals where the robot’s automatic speeds may fall short in smoothing the cut surface (typical depth 20-80 mm). Compatible with any Aqua Cone® end, this nozzle seamlessly integrates with all lances, elbows featuring female Aqua Cone®, lance extensions, and Rotolances (with an Aqua Cone® adapter).

  • Triple nozzle

    The Triple Nozzle further divides water jet power, covering three times more area for consistently smooth cuts, even at shallow depths of 10-50 mm. Compatible with any Aqua Cone® end, this nozzle seamlessly integrates with all lances, elbows with female Aqua Cone®, lance extensions, and Rotolances (with an Aqua Cone® adapter).

  • Ceramic nozzles

    By using Aquajet’s acclaimed ceramic nozzles and seals, the Dual and Triple Nozzle heads guarantee consistent and reliable performance, upholding the highest quality standards synonymous with the Aquajet brand.

  • Spraybar

    The Spraybar configuration on the Rotolance stands out for its exceptional effectiveness in surface treatment, encompassing cleaning, light removal, and preparatory work for roughening concrete surfaces. Through rotational hydrodemolition, it offers a removal capacity of up to 10-15 mm. This configuration excels in various tasks, including paint, rubber, and rust removal, making it a versatile and ideal choice for a wide range of hydrodemolition projects.

  • Cross nozzle

    The cross nozzle configuration option is availabile for all Rotolance models. This configuration stands out for its unique approach, employing two intersecting jets that cancel each other out at a specified depth. This design ensures tailored removal to an exact depth, with standard options available at 30 mm, 60 mm, and 100 mm. Depths in between can be achieved by adjusting the power head’s height.

    There are two primary scenarios for using the Cross nozzle head:

    1. When a specific removal depth is mandated, and selective removal is undesired. The jets cancel at a specified depth, allowing for precise control.
    2. When there’s a risk of blow-through a structure, either due to proximity to the target depth or sensitivity in the surrounding environment.

    Due to the jet’s canceling characteristics, careful consideration is necessary for robot settings to avoid excessive power cancellation and optimize performance.
