The centralizer is a 360° ring mounted on an Aqua Spine base that can be used for treating pipes or round tunnels from the inside. The power head can work a pre-set angle inside the tunnel or it can work the full range 360°.
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
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.
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.
Centralizer rings are available in following diameters:
1,0m (fits 1,5-2,0m tunnel)
1,5m (fits 2,0-2,5m tunnel)
2,0m (fits 2,5-3,0m 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.
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.
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.
