Hardi quintastream

[Secret Agronomist]

I've narrowed nozzle choice down to quintstreams for liquid fert, on a bateman with flow control.
Looking at doing rates from 180 to 330L/ha of different products.
What's the sort of minimum pressure I could operate these at? Probably need to be 10kph or less on headlands and wanting 14 in the middle, for the highest rate I think size 10 would be the best but that would be up at 2.5bar at 14kph (is that pressure too high?) and probably about 1 at slower speeds. Would air shut offs open at such a low pressure?

I didn't like the quintastreams. It didn't seem to matter what height the boom was the streams from next door nozzles would always land in the same place so there was a big gap between lines of fert.
We now use Hypro, which I would recommend.

You could relieve me of the quintastreams for a small consideration, I can have a look and see what I have got if you like.

We use either white or light blue caps for similar application rates to your requirement. Never had your problem SB?

Just the same as when a dribble bar spins round!
I quite like the idea of the lower rates at the outside so there is a bit more leeway on height. I assume there is no more risk of blockage with the outside holes though. Is it metered by the size of the individual holes or is there a metering orifice or something?
