A practical, affordable and reliable means of selecting different spray nozzles at the flick of a switch will be launched at the Precision Farming Event – Wednesday, March 5 at the East of England Showground – by Pentair Hypro, Britain’s leading producer of precision-manufactured spray application equipment.The new Duo React nozzle body will enable operators to easily switch between pesticide and fertiliser nozzles, between nozzles of different sizes to cover a wide range of application rates, and between nozzles with different spray characteristics – standard and low drift, for example.“Changing nozzles as the target or conditions dictate is crucial to get the best performance from agrochemicals,” emphasises Roger James, Pentair Hypro’s product manager. “Duo React allows the most common nozzle change-overs to be made with the flick of a switch, with all the advantages of a twin sprayline installation but without any of its drawbacks. “We learned from farmer experience of other rather complex and costly systems that our key design priorities should be to make Duo React a compact and inexpensive unit that is above all simple to use,” he adds. “It looks familiar, fits neatly on a spray boom and is, indeed, easy to use.”The new system will be available as original equipment on new sprayers. In addition to easy nozzle switching, it can provide section control to minimise over-spraying at angled headlands and in short-work.Pentair Hypro has earned an enviable reputation for innovation in spray application technology and for responding to the suggestions of farmers, contractors and sprayer operators for new and improved techniques.In recent years, the engineering team at the company’s Longstanton base near Cambridge has developed technologies producing the finest air-included sprays from the popular Hypro GuardianAir and the GuardianAir Twin drift control nozzles.The sprayer filling process has been transformed for many operators by using the Hypro ProClean rotating jet and ProClean Plus blade jet nozzles for faster container rinsing using less water.Together with the compact five-stream Hypro ESI liquid fertiliser nozzle, all these efficiency-improving developments will feature on the Pentair Hypro stand at the Precision Farming Event, where the features and practical advantages of the new Duo React nozzle body will be explained.
