Pulse width modulation sprayers: what we have learnt, correct operation and looking ahead
- PWM sprayers are continuing to improve with new technology providing more consistent performance, individual section control and turn compensation
- Constant pressure maintains droplet size and spray quality over a range of speeds
- Low duty cycle operation can result in poor coverage especially with 10Hz systems
- Newer systems have high cycle frequency (15/30/100Hz) and combine other standalone spraying systems
- There are many misconceptions about the effective working speed range, correct nozzle size and determining the correct pre-set pressure
- When set up and operated correctly, PWM sprayers perform accurately.
