Duct
desilting jetters
Flowplant has built cable duct desilting jetters for over 30 years — clearing thousands of metres of blocked ducts and speeding up the roll-out of fibre optic cable.
Clear the duct instead of digging it up
Cable duct desilting machines use the unique Harben diaphragm pump to create a pulsing water jet that clears silt blockages from long lengths of underground cable duct.
Silt trapped in long ducts can be difficult to remove, but a Flowplant desilter clears even the toughest blockages in minutes — avoiding civils work on old ducts that would otherwise need digging up and replacing.
- Pulsing Harben jet loosens and washes out compacted silt
- Low pressure, very little water — even on 500 m runs
- Faster fibre roll-out with ducts ready for new cable
From blocked duct to cable pull
Loosen
A powerful pulsing water jet first loosens the compacted dirt.
Wash out
The jet then washes the silt out of the duct.
Pull through
With the duct clear, engineers can easily pull through additional fibre optic cable.
Scale up
Larger hose reels, lightweight hoses and metre counters help on long runs.
Three desilting jetters
The Flowplant duct desilter range extends to three models.
Thousands of kilometres of duct cleared
Hundreds of Flowplant desilters have been used to unblock and desilt thousands of kilometres of fibre optic cable duct. Much development has taken place since the first Harben duct desilting system was approved.
Flowplant are members of the FTTH Council Europe.
