What Heliscreen sizes are available?
A. The diameters of Heliscreen available are 300, 500, 700 and 1000 mm. The effective lengths of screens range from 1.5 m to 7 m in 0.5 m increments up to 4.0 m then 1 m increments up to 7 m. When considering a particular spill flow, more than one Heliscreen may be available for selection. The engineer can decide which to opt for by considering the weir length required.
