WARNING: the indications to follow for using chemical products are indicated in paragraph 2.2.1.

6.1DESCRIPTION OF THE DIFFUSERS

The distributor accessories of the TurboTeuton range are equipped with variable diffusers (FIG. 18) so you can direct the airflow (and consequently the treatment) onto the vegetation to treat on the basis of your needs. According to the configuration of the accessory the diffusers have outlet mouths with different shapes and sections. The diffusers can be equipped with a double series of non-drip jets on request (FIG. 19).

6.1DESCRIPTION OF TYPE OF JETS

Various types of jets are fitted; with a single or double head. Generally they have a non-drip diaphragm and are made out of brass, suitable for pressures up to 40 bar, some models are nickel plated. The jets can be equipped with different types of nozzles, changing the locking ringnuts. The jets used normally have high volume, Ø18, ceramic plates and low volume conical nozzles (Albuz ATR or Teejet TXB). The jets for cannons have a jet holder with adjustable delivery and spray that has high volume, ceramic plates, Ø15 instead of 18.

All the jets normally used have three positions (FIG. 21):

a)spray - if the nozzle is pointing outwards, away from the blower group, parallel with the non-drip valve

b)closed - if the nozzle is at 90° with respect to the non-drip valve or, for the single jet if it is facing inwards towards the blower group

c)nozzle second spray - when these are pointing towards the outside of the blower group parallel with the non-drip valve.

6.2DESCRIPTION OF TYPE OF NOZZLES

The nozzles are extremely important to obtain a correct distribution on the vegetation to be treated. Poor quality or worn nozzles have a tendency to create unevenly treated strips.

The nozzles are produced in various sizes, to work with a precise pressure range, to create certain types of larger or smaller drops; using nozzles for a purpose they are not envisaged for prejudices the precision and duration of the nozzles.

6.2.2 LOW VOLUME CONICAL NOZZLES (150-500L/HA)

Made of two ceramic pieces with colour-coded plastic inserts, they are available in various sizes identified by the colour (see table 3 page 32). They have been specifically designed to obtain a large number of small drops with strong turbulence even at low pressures (2-3 bar). This turbulence makes them suitable for penetrating luxuriant vegetation and so they are suitable for fungicides and insecticides. The nozzles of the TR Lechler and TXA Teejet series are in this category.

6.2.3 ANTI-DRIFT NOZZLES

Specific anti-drift nozzles are available from Unigreen. The main characteristic of these nozzles is that they eliminate the fog effect caused by the presence of drops that are too small and are particularly sensitive to drifting. For further information please contact Unigreen for the relevant instruction handbook.
