Circulation of the chemical solution through the complete nozzle tube as soon as the spraying pump is switched on.
Spraying fluid therefore is always at the nozzle, even with the spraying apparatus switched off
When switching on a section or the entire spraying line for the first time, the chemical solution is available directly and in a well-mixed way.
Prevents deposits and blockages
Nozzle cleaning
Simple cleaning by circulation: suction side of the pump is set to fresh water – now clear water circulates in the nozzle line – then spray for a few seconds and all nozzles are cleaned.
Circulation as far as the nozzle + nozzle cleaning
