The innovative design of the nozzle achieves a spray with a large outlet angle. This is characterised by an uniform liquid distribution as well as a fine droplet spectrum with a low specific air consumption. The large free cross-sections of the nozzle also allow atomization of viscous or solid-laden liquids. Efficient cooling and conditioning ...Web

Lechler VarioJet nozzles atomize according to the principle of internal mixing. With this twin-fluid nozzle, the water is fed in axially via a bore hole. The liquid is split up into a thin liquid film. This thin liquid film is split into finest droplets by the atomizing air in the mixing chamber. The resulting two-phase mixture is then atomized ...Web
