  • Public and private parking areas.
  • Residential developments.
  • Distribution yards.
  • Industrial estates.

Description

ACO Q-Brake Vortex is a vertical vortex flow control designed to regulate storm water flow before it discharges into watercourses or sewer networks. Unlike more conventional methods, for example orifice plates or sized pipework, ACO Q-Brake Vortex is less prone to blockage and permits higher flow at a lower head of water, as a vortex flow control allows an outlet orifice of 4–6 times larger cross section to be used.

It is fitted with an integral bypass door which in the event of a blockage can be opened so the unit can be drained of water. A stainless steel wire attached to the bypass door is run to cover level and provides control of the bypass door. Once the water level within the manhole subsides the unit can be cleared. Manufactured from grade 304 stainless steel, each ACO Q-Brake Vortex is individually configured to suit specific performance criteria. All seams are continuously welded in accordance with BS 4872 for maximum strength.

Benefits:

  • Controls discharge flow into watercourses or sewer networks.
  • Provides predictable control performance.
  • More efficient than conventional orifice or pipe controls so reducing the required storage volume.
  • Self-activating system.
  • Minimizes the risk of blockage.
  • Reduces the need for maintenance.
  • Reduces the need for unnecessary man access.
  • Simple installation.
  • Fits a range of manhole designs.
  • Durable and corrosion resistant system.
  • Individually configured to suit specific performance criteria.

Applications:

  • Commercial and retail developments.
  • Hard landscaping.
  • Public and private parking areas.
  • Residential developments.
  • Distribution yards.
  • Industrial estates.
