StrictSprayPlus
No more skips with our PWFM system
When it comes to protecting your crops and optimizing every drop of spray, precision isn’t a luxury, it’s a necessity. That’s why Agrifac developed StrictSprayPlus, an intelligent spraying system that ensures maximum accuracy at the nozzle level, even at variable speeds and in challenging field conditions. This advanced technology automatically controls each individual nozzle, ensuring uniform coverage and minimal overlap.

While pulse-width modulation (PWM) systems were originally developed to increase work rates, their true strength lies in enhancing accuracy and reducing input waste.
Traditional spraying applies a uniform rate across the entire field based on average crop needs. In reality, this often leads to over-application in some areas and under-application in others, causing uneven coverage and unnecessary product use.
Agrifac addresses this challenge with StrictSprayPlus, our advanced Pulse Width Frequency Modulation (PWFM) system. By pulsing each nozzle up to 100 times per second, StrictSprayPlus delivers a consistent spray pattern and flow rate, regardless of changes in speed, turning or terrain. The result? Optimized application, improved efficacy, smarter use of your inputs and no more skips.
Individual nozzle control

To ensure precise application, StrictSprayPlus calculates the speed and target spray volume for each individual nozzle. Based on these values, the system determines exactly how much each nozzle should spray at any given moment.
Flow rate is controlled by adjusting the duration that each high-speed switching nozzle, capable of pulsing up to 100 times per second, remains open or closed. By finely tuning the ratio and timing between these open and closed states, the system delivers accurate spray volumes while keeping the switching frequency as low as possible. This not only ensures excellent coverage and a consistent spray pattern but also helps extend valve life by reducing wear on the components.
This level of precision translates directly into lower input usage, minimized environmental impact and maximized crop health. Whether navigating curves, varying terrain or changing speeds, StrictSprayPlus adapts instantly to ensure that every plant gets exactly what it needs.
Three key features for precise application
1. Individual nozzle control: To prevent overlap and overdosing, each nozzle can be controlled independently. This allows precise application, reduces input waste and minimizes environmental impact.
2. Turn compensation: When turning, the nozzles on either side of the boom move at different speeds, the outer nozzles cover more ground, while inner nozzles cover less. To maintain uniform coverage, outer nozzles must spray more and inner nozzles less. StrictSprayPlus is the first system to fully compensate for turns, ensuring consistent coverage across the entire boom, even in curves.
3. Pressure-independent speed control: In traditional systems, adjusting the spray volume means changing water pressure, which alters the flow rate, spray pattern and droplet size. With StrictSprayPlus, spray pressure remains constant, so your spray pattern and droplet size stay consistent, regardless of speed or flow rate. This ensures accurate, reliable application under all conditions.
StrictSprayPlus is available on the Condor, Condor Vanguard, Vanguard 55, Vanguard 67 and Endurance 80.
