The function of the patented Energy Dissipator (ED) is to control the flow rate and hydraulic profile in piping systems with significant changes in elevation. The ED is a small unit which can dissipate hundreds of metres of head with a very compact footprint.
Where Is It Used?
The unit is primarily used on backfill systems, but can be used on any system where there are significant changes in elevation. EDs are installed at the bottom of steep vertical piping sections to maintain full flow conditions in the piping and to prevent problems associated with slack flow.
The ED can also be used at valve stations to provide bypass pipeline resistance to achieve controlled pipeline shutdown with minimised valve wear.
Why Do I Need It?
Many backfill systems suffer from problems associated with slack flow, such as accelerated pipeline wear and pressure transients.
Installing the ED at the bottom of a shaft column can eliminate slack flow and allow for controlled pipeline operation without pressure transients.In systems operating with a batch water and slurry mode the ED can be used to control the hydraulic gradeline of pipelines to maintain a positive pressure in the line under varying operating conditions.
