Developed specifically for drift reduction with pulse width modulation (PWM), the new AccuPulse TwinJet nozzle from TeeJet uses a novel, patent-pending recirculating flow to improve spray distribution and create large droplets.
This provides a new option for PWM users looking for a replacement for existing air induction nozzles, which cannot be used with the system. This is because the pulsing – the quickly on/off switching, causes the venturi to break down and liquid can squirt out of the air inlets.
The non-air induction, twin spray tip forms two 110° patterns, spaced 60° apart and creates drift resistant, ultra coarse and coarse droplets. It has a suggested spray pressure range of 1.5-7 bar and is available in eight sizes from an 015 (green) to an 08 (white). Operating at 3 bar the 03 (blue) creates ultra coarse droplets, at flowrate of 117 litre/min at 12km/h.
To reduce drift the nozzle creates large drops, by passing the liquid through a flow control pre-orifice before it enters an induction chamber. Here it recirculates through special ducts before passing out through one of two concave exits. This process results in low velocity, ultra-coarse droplets.
TeeJet says the coverage, droplet size spectrum and twin spray pattern from AccuPulse make it ideal for a variety of pre- and post-applications of systemic herbicides, such as glyphosate.
