Lechler IDTA 120-04C: 75% drift reduction – JKI approval

Lechler has received JKI approval for its IDTA 120-04C in the 75% drift reduction class after LERAP**** (4 star) rating.

Lechler IDTA 120-04C: Jetzt mit JKI Anerkennung 75% Abdriftminderung im Ackerbau

The IDTA 120-04C is now the first nozzle size from the Lechler series of "Asymmetrical twin flat spray air injector nozzle" in the German list of drift reducing plant protection equipment for arable crops. From now on, an extended pressure range of 1 to 8 bar is available allowing an even more flexible application. Further IDTA nozzle sizes will follow.

Following the compliance with distance requirements regarding surface waters and buffer zones, 75% drift reduction is achieved with the IDTA 120-04C (see JKI and LERAP lists) when spraying a 20 m wide area along the field border at 1 - 2 bar spray pressure and a boom height of 50 cm above target. The same conditions of use apply in combination with the border nozzle IS 80-04. In order to prevent spraying into the frame of the sprayer in the middle section, a mixed setting of 6 x ID-120-04 POM or 6 x ID-120-04C is allowed with the same drift reduction potential. Distance requirements for plant protection products are easy to implement with the IDTA 120-04C.

The Lechler IDTA – an asymmetrical twin flat spray air-injector nozzle – sets a new benchmark in the twin flat spray technology. Application technology as well as user safety are much improved. The innovative features are the reasons for the numerous awards at home and abroad.

Angling of spray 30° to the front and 50° to the back has shown best results in numerous tests with regard to increased deposits at vertical targets and evenly distribution on front and back - especially at higher forward speeds in the field.

Due to the asymmetrical angling of the twin flat sprays with spray angles of 120° to the front and 90° to the back, results in the same effective spray width at the target area. No other available asymmetrical twin flat spray nozzle show these features. Overspray along field borders is technically impossible.

In combination with an IS 80 border nozzle of same size at the end of the boom, a sharp demarcated application along field borders is possible.

Spray volume to the front is 60% and to the back 40% of total. At higher forward speeds, the asymmetric volume distribution results in a uniform deposition on vertical targets in direction of travel front and back.

Droplet sizes at front jet are slightly smaller than at the rear jet. The increased number of droplets in the spray results in an optimized coverage. Compared to standard air injector flat fan nozzles the overall coverage at vertical targets is up to double with IDTA.

User safety has been in focus too. The new design of nozzle and cap in one piece is well hand held and eases assembly on the boom. The new injector design (patented) enables manual removal without any tool – even the user is wearing his protection gloves. Therefore, the user has optimal protection when cleaning the nozzles.
