Description

The full-circle version of the brass Koala with two nozzles, which the importer offers for frost protection. Flow runs from 14.2 to 35 l/min at a range of 9.5 to 16.5 m, with a 26° jet angle and a Ø 4 mm nozzle, at low to medium-high pressure. The second nozzle breaks up the jet and wets the ground close to the unit as well, and in frost protection what counts is exactly that continuous, even wetting of blossom and buds. It is used in orchards and vineyards, where a single spring frost can take the whole crop.

Applications

Solid set systemsIn solid set systems the sprinklers work on a pipe grid, where overlap, distribution uniformity and water use matter most.
