Introduction

Hydro-jetting is the use of water pressure and water volume to effectively clean surfaces. Hydro-jetting employs special purpose pumping equipment and generates water pressures up to 40,000 psi. The benefits of hydro-jetting include the rapid, environmentally sound and safe cleaning of many varied types of surfaces.

In addition to the high pressure water pumps, the selection of special purpose accessories and nozzles is critical to the success of every project. Barry Bros. is committed to continually investing in the latest technology in nozzles to ensure we can offer our clients’ solutions to their cleaning needs.

Aquacutter

After building its own high pressure water blasting rig to remove the unsound concrete on Nauru House in Melbourne, Barry Bros. decided to buy a specialised rig using the latest technology and capable of greater production. After looking at machines around the world, it settled on the Swedish Aquajet HV450 rig.

One of the features of hydro-demolition is that it is able to detect unsound concrete and selectively remove it while leaving the sound concrete. This makes it much more efficient than the traditional jack hammering method. The Barry Bros. rig has an input of 450 hp, operates at a pressure at 1,000 bar and requires 180 litres of water per minute.

Applications

Applications include; General hydro-jet cleaning, Tube bundles, heat exchanger and evaporator cleaning, Automated tank cleaning, Pipe and line cleaning, Automated boiler cleaning, Automated rotary / tubular air heaters cleaning systems, Ash & cooling water line cleaning, Floor cleaning, Paint removal, Concrete spalling removal and Concrete demolition.
