RS II-3 Spillback Nozzle

The new generation of Lechler spillback nozzles brings proven technology to a higher level.

Spillback nozzles are single-fluid nozzles that atomize the liquid as a hollow cone. Compared to regular single fluid nozzles, the water is fed to the nozzle with a constant feed pressure (e.g. 507 psi), independent of the atomized flow rate.

By opening a control valve in the return line, a partial flow of the feed flow rate in the nozzle is returned to the water tank and the injection flow rate of the nozzle is controlled. 

The maximum atomized flow rate is achieved with the control valve closed. Uniform and fine liquid atomization is achieved across the entire control range.
