Completely reproducible spray results –
The SCHLICK Module System Range 940: extremely flexible to use

  • The standard air cap and flat spray cap can be quickly and simply changed by hand 
  • Completely homogeneous and reproducible spray results
  • Extremely easy to adjust for maximum flexibility
  • Significant reduction in maintenance downtimes thanks to easy access to all components
  • Wide range of installation options thanks to modular construction
  • Functional components with a surface quality of Ra < 0.8 (also available as designs conforming to FDA)

External-mix two-substance nozzles allow independent control of the flow rate and fineness of the atomization. The flow rate for all models is controlled through the liquid pressure difference. In the model with a regulating pin, the flow rate can also be regulated by the pin setting.

The SCHLICK model 940 is manufactured as a modular construction. This means that it can easily be rebuilt into other designs. Replacement parts are available for all individual parts, with reproducible results ensured.

Standard bore holes for liquid operation are available with 0.5 / 0.8 / 1.0 / 1.2 / 1.5 / 1.8 / 2.0 / 2.2 mm.
Customized bore sizes are possible starting from 0.3 mm upwards in 0.1 mm steps.

Materials: Acid-resistant stainless steel, heat-resistant stainless steel, brass, tantalum, titanium, hastelloy, inconel, PVC, PTFE, polypropylene, other materials available on request.

The scatter cone can be set between 10° and 40° through adjustment of the air cap position. By turning the air cap backwards, the air flow rate is reduced and the scatter cone becomes more focused. By turning the air cap forwards, the air flow rate and scatter cone become larger. Depending on the intended use, the required cap setting must be determined through trial and error.

Cap setting 0 = nozzle closed
Cap setting 5 = normal setting

Two vertically arranged SCHLICK liquid inserts. The insert on the right has a short pipe-like extension at the top.

All nozzle forms can also be delivered with extended liquid inserts. These optimise the atomization of tacky liquids and minimise build-up at the air expulsion hole.

  • Atomisation technology for cigarette production

    Moistening, casing and flavouring

    For decades, Düsen-Schlick has been supplying systems manufacturers and cigarette producers with process-optimised atomisation technology. Moistening and flavouring are core processes in the primary stage of tobacco processing. These are ultimately responsible for the flavour and quality of the final product. Properly measuring flavouring additives and uniformly moistening leaves and ribs ensure optimum cutting and drying properties. This also creates benefits for the downstream (secondary) stage of cigarette production.

    Nozzles and injection lances in use with flue gas denitrogenation installations

    The SNCR and SCR procedures were developed for flue gas denitrogenation in order to meet the strict air purification requirements. Injection lances for the defined insertion of the reducing agent are an important component of both processes. These differ in their structural and procedural design depending on the application.

    Atomisation technology in nitrogen oxide reduction using urea

    During flue gas denitrogenation, the addition of a reducing agent is used to transform nitrogen oxides into a substance that can be emitted without causing any damage or can be used again. The reducing agent ammonia is increasingly being replaced by innocuous urea. However, urea has a tendency to crystallise during atomisation. When observing the nozzle systems used in urea atomisation, it can be seen that trouble-free operation is not always guaranteed.

  • And it burns

    Nozzle systems used in combustion processes

    Due to poor or incomplete combustion of the medium, soot is produced, and at the same time the emission values in the combustion chamber increase. With liquid fuels, combustion al­ways takes place in the gas phase: The liquid fuel is first atomised, then vaporised, mixed with air, and finally burned in the gas phase. This article shows how atomisation can be influenced by various special nozzles ...
