Duct desilting jetters
Flowplant has been building cable duct desilting jetter for over 30 years and their machines have cleared thousand of meters of blocked ducts. They have significantly sped up the roll out of fibre optic cable and and helped civils avoidance – clearing old ducts that otherwise would have required dig up and replacement.
Cable duct desilting machines use the unique Harben diaphragm pump to create a pulsing water jet that can clear silt blockages from long lengths of underground cable duct.
Silt trapped in long underground cable ducts can be difficult to remove but their duct desilting jetter can clear even the toughest blockages in minutes. A powerful water jet first loosens and then washes away compacted dirt. This leaves the duct clear, so that engineers can easily pull through additional fibre optic cable.
The Flowplant duct desilter jetter range extends to three models.
Hundreds of their desilters have since been used to unblock and desilt thousands of kilometres of fibre optic cable.
Much development has taken place since the initial Harben duct desilting system was approved. Larger hose reels, lightweight hoses and meterage counters are a few of the accessories available.
The Harben desilting system has cleaned ducts up to 500m long with low pressure and very little water.
