Aqua Centralizer

The Aqua Centralizer is a 360° ring system designed for hydrodemolition in round tunnels and pipes. Mounted on the Aqua Spine base, it handles both horizontal and vertical tunnels with ease, offering adjustable 25° lance angles and full 360° rotation.

Centralized power

The Aqua Centralizer can operate both in horizontal tunnels or vertical/inclined tunnels where it can be positioned with a hoist device. The power head and ring assembly indexes automatically along the spine rail to complete a whole tunnel section. Available in multiple diameters, it adapts to tunnels from 1.5 to 3.0 meters and automatically indexes along the spine rail for complete coverage. With quick setup and robust triple support wheels, the Aqua Centralizer ensures efficient, precise treatment for various tunnel and pipe applications.

Features

  • Adjustable lance angle

    With the 25° adjustable lance angle and adjustable stroke of oscillation, the head can be reversed to handle both inside pipes and outside pillars if used on the Circular Power Head.

  • Connect the Power head

    The power head is easy to attach to the ring curved rail and secured with one single bolt. The Spine roller is attached to the spine rail in the same way.

  • Adjustable diameter

    Centralizer rings are available in following diameters:
    1,0m (fits 1,5-2,0m tunnel)
    1,5m (fits 1,9-2,5m tunnel)
    2,0m (fits 2,4-3,0m tunnel)

    The bottom of the power head slides 250mm in and out to cover different pipe diameters in the 0,5m range between the different ring diameters.

  • Support wheels

    Triple support wheels that center itself and crank handle with two gear ratios, low and high. Centralizer support fits in tunnels with diameters 1,5-3,0 meters.

  • Spine system

    The base of the Aqua Centralizer is the triple rail from the Aqua Spine system, which means it can be built up to 6 meters between the two centralizer supports. The Triple rail can also be mounted in front of the support to reach all the way into a dead end of a pipe.
