Lechler spillback nozzles atomize fluids as fine hollow cone. This special single-fluid nozzle works according to the pressure atomization principle. Compared to regular single fluid nozzles, the water is fed to the nozzle with a constant feed pressure (e.g. 35 bar), independent of the atomized flow rate.
The amount of liquid injected is adjusted via a control valve in the spillback line, whereby part of the flow is taken from the inlet flow rate and returned to the tank. The maximum atomized flow rate is achieved with the control valve closed. Uniform and fine liquid atomization is achieved across the entire control range.
The nozzles themselves are designed maintenance friendly and can be quickly cleaned and replaced on the nozzle lances without must effort.
Our nozzle lances are tailored customized versions that are each manufactured project-related when considering the local and process-related circumstances. We recommend a wear protection tube or a wear tray with reinforces wall thickness to increase the service life.
Depending on the customers requirements, the lances can be equipped with the following options, amongst others:
