Nozzles

The function of nozzles is the dosage, distribution and atomisation of the spraying liquid into drops, so that the liquid is distributed evenly and in the correct dosage over the surface to be covered.

The choice of nozzle has a great effect on the spraying result. The choice is determined by the working principle of the chemical (systemic or contact chemical), the permeability of the crop, the weather conditions, the type of crop protection and the required application rate. The choice of nozzles is dealt with in more detail in "Nozzle selection" in the section entitled "Working with the machine".

The machine can be supplied with the following types of nozzles as standard:

• XR 80° TEEJET ® extended range flat fan nozzles in sizes 01 up to 08 (stainless steel)
• XR 110° TEEJET ® extended range flat fan nozzles in sizes 01 up to 08 (polymer or ceramic)
• TT 110° TEEJET ® anti drift precision deflector nozzles in sizes 01 up to 08 (polymer)
• AI 110° TEEJET ® air induction (Venturi) nozzles in sizes 015 up to 08 (stainless steel)
• ID 120° LECHLER ® air induction (Venturi) nozzles in sizes 01 up to 08 (polymer or ceramic)
• IDK 120° LECHLER ® air induction compact (Venturi) nozzles in sizes 015 up to 05 (polymer)

The type of nozzle is indicated on the coloured nozzle tip.

A) Nozzle type; the two letters indicate the type:

• XR:TEEJET ® Extended range (extended pressure range)
• DG:TEEJET ® Drift Guard (anti-drift)
• TT:TEEJET ® Turbo (coarse droplets)
• AI:TEEJET ® Air Induction (injector)
• ID:LECHLER ® Injektor Düse (air induction nozzle)
• IDK:LECHLER ® Injektor Düse Kompakt (air induction nozzle)

B) Brand name

C) The first two or three digits indicate the spray angle of the nozzle in degrees, 80°, 110° or 120°.

D) The final two or three digits indicate the capacity of the nozzle. The indication is an American size, namely the volume in gallons/minute at a pressure of 40 psi. The higher the digit, the larger the volume. A size 06 nozzle has double the volume of a size 03 nozzle, for example.

E) If the first letter behind the digits is a "V", this refers to VisiFlo colour coding (ISO standard).

F) The final letter indicates the material the nozzle is made of:

• P: polymer
• S: stainless steel
• K: ceramic

Special nozzles are often used for application of liquid fertilizers, such as 3-hole or 7-hole nozzles, drop pipe nozzles or drop hoses.
