The difference between the 4 swirl plates is the droplet size. The blue swirl plate has a very fine droplet spectrum, the grey a fine droplet spectrum and the black swirl plate has a medium droplet spectrum. The white swirl plate has a medium droplet spectrum and is giving a full cone spray.
A large drop adaptor (371077) is available for the grey swirl plate. This adaptor changes the droplet spectrum to very large droplets.
HARDI 1553 Cone nozzles are used with one of the four available swirl plates for hollow cone and full cone spraying. The hollow cone nozzle can be used for pesticide application on boom sprayers, mistblowers or knapsack sprayers. The HARDI 1553 cone nozzle can also be used without swirl plates for solid stream application
65° Flat spray nozzles
This nozzle provides an elliptical spray pattern (FlatFan) with a 65° angle. A uniform distribution is obtained, with correct overlap between spray patterns from adjacent nozzles.
This nozzle has additional applications for industrial purposes.
- Recommended pressure range: 1.5 to 5 bar
- Recommended boom height above target: 70 to 80 cm.
25° Flat spray nozzles
This nozzle provides an elliptical spray pattern (flat fan) with a 25° angle. The narrow spray angle results in a high impact spray, which is well suited for cleaning as well as for spraying trees and bushes, where a long range is very useful.
- Pressure range: 2 to 25 bar
This nozzle consists of a synthetic tip and a blue swirl plate (370156). The droplet spectrum is very fine. The low capacity and extremely fine atomization make this nozzle useful for special purposes such as adjustment of air temperature and humidity in hot climates.
- Pressure range: 2 to 5 bar
- Hollow Cone nozzle
- Very Fine droplets
Deflector spray nozzle of synthetic material. This nozzle type produces a round spray pattern (360°). The speed of the droplets is low, producing a slowly dispersing cloud. The atomization and dispersion are optimal between 1 to 5 bar. Useful for raising the humidity in greenhouses etc.
- Pressure range:1 to 10 bar
Multi-hole rinsing nozzles
These nozzles are mainly used for washing out residues in chemical containers and bags. Can also be used for some irrigation purposes. Tests have shown that the most efficient way of cleaning chemical containers is by using these rinsing nozzles.
|Nozzle 1 - with all the holes||Nozzle 2 - with pointed tip|
This nozzle type is used for tank agitation. The venturi effect of the nozzle increases the agitation several times in relation to the liquid passing through the calibrated part of the nozzle. Useful for a fast and continuous mixing of for example pesticides in suspension.
- Pressure range: 1 to 15 bar
Tank cleaning nozzles
This nozzle is made for cleaning of the insides of sprayer tanks. The different angles of the 8 solid streams ensure an excellent rinsing of the entire inside surface of the sprayer tank.
Hardi recommends the use of a cleaning agent to ensure sufficient cleaning of the tank.
- Rotating nozzle for tank cleaning
- 8 solid streams at high velocity
