Heavy duty cleaner from Aquajet

Jon Lawson

Aquajet Systems has launched the Aqua Centraliser. It’s designed for effective cleaning or removal of concrete, paint, rust and coatings along an entire section of horizontal, vertical or inclined tunnels and pipes. It works in conjunction with Aquajet’s Aqua Cutter Hydrodemolition robots and high-pressure Aqua Power Packs to provide strategic concrete removal in roadbuilding, wastewater and industrial plant applications.

Roger Simonsson, Aquajet Systems managing director commented, “The Aqua Centraliser integrates key components of several of our existing designs to provide operators a new solution for working in pipes and tunnels more effectively than before.”
The Aqua Centraliser uses elements of the Aqua Spine as the base for the unit while incorporating technology from the Circular Power Head attachment for concrete removal and cleaning applications. This includes a 360 degree ring and robotic power head with a 25 degree adjustable lance angle and variable stroke oscillation. The power head offers adjustable working angles from 0 to 360 degrees and automatic indexing along the spine rail, minimising downtime from repositioning and optimising productivity. Combined with one of Aquajet’s Power Packs, which provide a pressure up to 40,000 psi, this flexibility offers contractors the power and precision to effectively clean steel pipes and remove concrete inside tunnels and pipes.
The modified Aqua Spine that makes up the base of the Aqua Centraliser can span up to 19.7 feet (6 meters) between a pair of triple support wheels. Supports feature adjustable caster wheels that are designed for 4.9- to 9.8-foot-diameter (1.5- to 3 metre diameter) tunnels. For additional reach, the ring and circular power head can be mounted in front of the support wheels.
A single bolt attaches the power head to the circular rail, with the spine roller attaching to the central spine rail the same way. Additionally, the attachment’s power head can be reversed for effectively removing concrete on the outside of pillars and pipes.
