Streamline your low-to-mid-flow fluid chemical injection with the Hydro Systems MiniDos. Powered entirely by fluid pressure without electricity, this compact, water-driven proportional injector ensures consistent dosing accuracy even through fluctuating system pressures and flow rates. Crafted with a proprietary composite body that outmatches traditional chemical compatibility standards, the MiniDos features an integrated on/off switch that allows you to stop chemical mixing without shutting down your main water lines. Its advanced internal mixing chamber separates aggressive concentrates from the motor piston, safeguarding internal components and drastically extending equipment life.
