TWIN Air tech niqu e
G en eral in fo
With TWIN air assistance energy is added to the spray droplets to
improve control with the spray liquid. The main purpose of the T WIN
angling system is to counteract for the negative influence which wind
direction and dr iving speed have on the quality of the spray job. Fur the r
the "co- angling" af air and liquid can help "opening" dense crops for
better penetration.
This way TWIN makes it possible to:
• car ry the spray droplets safely to the target and increase plant
deposit.
• minimize off- target deposit due to wind drift or loss on the ground.
• open the crop and obtain good penetration e ven with a low
volume rate.
• ensure a high coverage.
The TWIN FORCE air system can be se t at any angle from 40° forward to 30° back (defined by the air stream). The fan spee d
is infinite ly variable and can produce from 0 to 35 m/s (78 mph) air spe ed at the air outlet. This equals from 0 to 2 000 m3
air/m boom/hour (3.872 CFM /A boom/hour).
