DYNAJET® FLEX OVERVIEW

The DynaJet Flex controller works in conjunction with an existing rate controller that regulates flow via a control valve or pump regulation to 

achieve a target application rate while maintaining target droplet size(s) when a speed change occurs. This system only works with automatic 

rate controllers that use flow based monitoring systems and not pressure based monitoring systems. Automatic rate controllers equipped for 

both flow and pressure based control should have the pressure-based system disabled to work in conjunction with DynaJet Flex.

The independent automatic rate controller loop performs the same as it would if the DynaJet controller were not present. The DynaJet Flex 

controller changes flow output to each individual nozzle based upon input provided from the operator about the optimum droplet size 

(pressure) for the application.

INSTALLATION 

CONSOLE

The DynaJet Flex console is designed to provide years of service under typical agricultural and turf operating conditions. A tight fitting 

enclosure means that typical dusty environments will not cause operational problems. While occasional splashing of water will not damage 

the unit, the DynaJet Flex console is not designed for direct exposure to rain. Take care not to operate the DynaJet Flex console in wet 

conditions.
