The advanced Twin Fluid low volume application system is an intelligent solution for high capacity spraying. It lets you stretch capacity, improve coverage and minimise soil compaction. Low rate application lets you cover many more acres with just one tank filling. In fact, the 4000 litre 840TF trailed sprayer equipped with the Twin Fluid system provides a capacity equivalent to a 10,000 litre unit using common application rates.
Twin Fluid Nozzles
-
With Twin Fluid nozzles, air and liquid are atomised and carry the spray solution to the target.
-
Droplet speed and entrainments are increased, allowing you to spray finer droplets, at lower spray volumes (80-150 l/ha).
-
The finer droplets let you spray in a wider range of conditions with much less susceptibility of drift.
Application Rate & Spray Quality
-
With the Twin Fluid system, both application rate and spray quality are always maintained.
-
The operator just has to select the desired application rate and drop size, depending on type of chemical and weather conditions.
-
Droplet size greatly influences plant coverage and chemical efficiency - see diagram, right.
Unique features of the Twin Fluid system include:
High Spraying Capacity
Spraying with lower volumes means less time wasted to refill and transport.
Adjustable Droplet Size
With one nozzle you can easily adjust the droplet size from very coarse to very fine from the tractor cab and without having to change the application rate. You can react to changing weather conditions on the go.
Reduced Drift.
With the same droplet size, you have less drift compared to conventional nozzles. It gives you more hours to spray and you can also spray more hectares during those hours with lower wind speed, higher humidity and lower temperatures.
Effective Droplet Spectrum
Spraying with finer droplets means less waste of chemical because of run-off from the target. This means a better spray disposition and the ability to reduce the chemical application rate when spraying contact fungicides.
Flow Rate & Speed Range
You can change the nozzle flow rate in a much wider range, without affecting the droplet size. This allows you to change the application rate on-the-go if you want to spray with higher or lower amounts on certain parts of the field (i.e. spraying weeds with herbicides or future variable rate application through GPS).
Twin Fluid System
With the Twin Fluid system, air is supplied by an oil free , air cooled compressor driven by the tractor PTO by means of a gearbox.
Onboard Wind Speed Sensor
With an onboard wind speed sensor, the actual weather conditions can be determined. The controller will recommend the operator the right droplet size or warn him when there is too much wind to spray.
