Arable
Auto-wash system
What are its uses?
Designed for an easier, faster and more efficient rinse process, reducing cross- contamination of pesticides.
Manufacturers have various names for this system.
How does it work?
Valves on the sprayer can be manually or automatically operated to select various wash programmes.
The aim is to reduce operator contamination caused by contact with the equipment or the sprayed crop.
The process can be completed while in the field, where multiple rinse actions can be carried out (this can be an automatic operation – while on the move with some equipment), therefore reducing the residual concentration in the tank, pump and plumbing.
Water is taken from the clean wash tank and diverted to the rinse nozzles positioned in the main spray tank.
Most clean wash tank contents hold a minimum of 10% of the main spray tank volume.
Possible problems
• The clean wash tank is empty. • There may be faulty valves/positions. • Wiring/air source issues. • The operator may incorrectly use the programme/controls. • The flush nozzles may be damaged, which prevents them from spinning.
