More details

Finest atomisation with mushroom head technology –
the SCHLICK module system range 938 and series 848, 0/28, 0/48

  • Very fine atomisation with the SCHLICK mushroom head technology
  • Convertible basic system also available with double air atomisation or with extended shaft version
  • 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)

THE specialist for the finest atomisation
Two-substance nozzles with mushroom heads can atomise liquids more finely than other two-substance nozzles through the mixing of liquid and atomising air at the nozzle exit. 

With the SCHLICK two-substance nozzles 938, 848, 0/28 and 0/48 the fluid is applied to a large specific surface through atomisation using compressed air, gas or steam – from 0.7 bar (g). The flow rate for all models is controlled through the current liquid pressure difference. In the model with a regulating needle, the flow rate can also be regulated by the needle setting. The nozzles are manufactured to a modular design and are available in various designs. Replacement parts are available for all individual parts and reproducible results are ensured.

The liquid should be free of solid particles. Due to the geometry of the nozzles only liquids with a low viscosity can be sprayed (depending on surface tension – max. 30 to 100 mPas). The droplet size can be set using the relationship of kilograms of air to kilograms of liquid.

Materials: Acid resistant stainless steel, heat resistant stainless steel, brass, titanium, hastelloy, other materials available on request.

Fittings made from plastic, nickel-plated brass; straight and angled versions

Fittings made from stainless steel 1.4404; straight and angled versions. 

Model 938 with straight air feed
Minimum liquid pressure difference required: 0.050 bar

Form 0 
Basic model with dummy plug. Designed for the atomisation of liquids that are either siphoned or fed by gravity at a slight gradient. For homogeneous distribution on large specific surfaces.

Form 4 
Version with a liquid flow control needle. This design is particularly suitable for applications or atomisation tasks with highly variable flow rates.

Form 5 
As form 4, but with a scale etched on the liquid control needle for fine setting of the flow rate, designed for research & Development, laboratories, etc.

Form 7 
Pneumatically controlled liquid shut off using the atomising air. The needle closes the nozzle’s liquid orifice automatically and abruptly. Perfect for marking, signing and cyclical spraying. Drip-free.

Form 7-1 
As form 7, but with needle operated  by independent  air supply. Leaving the atomising air to continue. Improving cyclical spraying, changes to process environment and no dripping, even with pressurised liquids.

Form 8 
With solenoid valve, standard design: 230 V, 50 Hz, 100 % ED, ambient temperature: max. 55 °C, enclosure protection IP 65, cycling frequency limited only by the changeover time

Forms

Model 0/28 with straight air feed
Minimum liquid pressure difference required: 0.050 bar

The performance data of the SCHLICK model 0/28 is identical to the basic model 938. The only difference between the two models is their design. Model 0/28 is – depending on installation – fitted with individual shaft lengths.

Model 0/48 with double air feed 
Minimum liquid pressure difference required: 0.035 bar

The model 0/48 works with double air atomisation. The result justifies the high energy consumption: Very fine droplets at a high liquid flow rate. 

Model 848 with double air feed  
Minimum liquid pressure difference required: 0.027 bar

Developed for maximum air flow rate: The model 848 is also equipped with double air atomisation and provides very fine droplets with a very high liquid flow rate.

  • 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.
