The Harben® cable duct desilting system was introduced in the 1990’s after successful trials with British Telecom.
Silt trapped in long underground cable ducts can be difficult to remove but our Harben desilters can clear even the toughest blockages in minutes.
Hundreds of our 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 can clean ducts up to 300m long with low pressure and very little water.
