06 Nov New from BfS – PulZar low drift jet for Pulse Width Modulation sprayers
Working with Capstan and Case, BfS has developed a low drift nozzle for use with Pulse Width Modulation (PWM) nozzle bodies.
Since the early days of the introduction of PWM, BfS have been marketing PulZar nozzles throughout north America and Canada and now the PulZar nozzle systems are being offered on machines coming onto the UK market.
PWM controls each nozzle separately, and the flow rate from each nozzle is managed by rapidly switching the nozzle control solenoid on/off. The duration that the nozzle is “on” is called the Duty Cycle and varying this duty cycle provides the operator with the ability to control the volume output from each nozzle.
- The system pressure, spray quality and fan pattern remain consistent.
- The system can cope with a five-fold change in forward speed without affecting output.
PWM bodies will enable the correct application from each nozzle even when going around a corner where the outer edge of the boom is ravelling much faster than the inner edge, so giving a lower rate of application. PWM corrects this by changing the duty cycle at each nozzle to compensate accordingly.
