The Harben® cable duct desilting system was introduced in the 1990’s after successful long term trials had taken place with British Telecom. Since then the system has been used by numerous contractors to unblock and desilt thousands of kilometres of fibre optic cable duct allowing new cables to be installed quickly and safely.
Much development has taken place since the initial Harben® duct desilting system was approved. A heavy duty pump with 30% more load capacity has increased work rates and improved pump couplings have meant longer service intervals. The Harben® desilting system can now clean ducts up to 300m long and as a result hoses and hose reels have also expanded to make the most of this extraordinary machine.
