New series of COMMANDERS

2 May 2013

On May 13th, HARDI North America will launch a new series of COMMANDER sprayers. The new series models are the 4500 (1200 gallon), 5500 (1500 gallon) and the 7000 (1950 gallon). These new models of COMMANDER sprayers have many new and updated features and one of the most important being the new fluid systems named "DynamicFluid4" .

Dynamic fluid system based on 4-sensor technology


The fluid system on the COMMANDER is a new concept developed to obtain shorter response time and thereby more precise application in the field. Powerful tractors with clutch free gearshift and CVT transmissions have given new driving patterns with more variance in the speed and faster acceleration, factors which together with GPS controlled section control is challenging for the performanceof the liquid system.

In a traditional fluid system the regulation is made on feedback from what is already “historical” data.For example the RPM is increased, and shortly after the flow will be too high at the nozzle. When that is measured, the spray computer will regulate the pressure down again but in the meanwhile the application rate has been too high.

The DynamicFluid4 system will calculate the consequences of the increased RPM and make the regulation instantly. The DynamicFluid4 property of proacting is based on 4 sensors in the fluid system measuring RPM, position of regulation valves, flow and pressure. Together with new software and new unique ceramic regulation valve, DynamicFluid4 is offering precision in the application rate giving the best performance available on the market.

Stability and safety

The sensors in DynamicFluid4 each have their individual task, but they will also work as back up for each other and the regulation will continue. Regulation can be done manually.
