The gas and steam specialists –
SCHLICK laval nozzles modell 630 and 555

  • Fluidically optimised to reduce noise during spraying of all gas or steam producing media
  • Designed for critical and extremely critical pressure relationships
  • Also available with head screw (model 630)
  • With an adjustable annular gap and therefore variable flow rate at the same pressure (Model 555)

SCHLICK steam and air jet nozzles are very well suited to spraying all gas or steam-forming media. The noise-reducing Laval nozzles can be used for critical and extremely critical pressure relationships.

Materials: Acid-resistant stainless steel, heat-resistant stainless steel, brass, PVC, PVDF, other materials available on request.

Model 630

was fluidically optimised and so reduces the operating noise volume.

The Laval nozzle is also available as the custom model 630 K  – with a head screw thread for fitting to walls – and 630 S1 – with individually adapted cut-out for welding to pipes etc.

Model 555

The distinct feature is the specially designed annular gap. By opening and closing this gap the air flow can be individually adapted at the same pressure.

  • Say Goodbye to Blockages

    Use of anti-bearding cap nozzles in fluidised bed systems

    Blocked spray nozzles are a widespread problem in fluidised bed systems in which very fine or tacky products are processed. By using ABC nozzles, the pharmaceutical excipient manufacturer DMV Fonterra Excipients has succeeded in avoiding unplanned downtimes. Düsen-Schlick Anti-bearding cap technology (ABC nozzles) is well-established in the field of tablet coatings.

  • Nozzle ABCs for power users

    State-of-the-art nozzle technology enhances tablet coating productivity

    Improved spray arm design and advanced nozzle systems cut set up time in half on state-of-the-art tablet coaters. This has big advantages for contract manufacturers who have find efficient ways of dealing with frequent changeover.

  • Process Engineering & Optimisation:

    Perfect atomisation without bearding

    Anti-bearding air cap ensures that droplets are well distributed, and that coating and moistening are homogenous. The type of nozzle used for coating and moistening determines the process result. Normally, flat spray two-substance nozzles are used for this process. A new, robust air cap withstands even the most adverse operating conditions and thus ensures a clean spraying process with the ideal drop size.

  • No weakness

    More operational safety in tablet coating

    In the pharmaceutical industry, flat spray two-substance nozzles are used in coating drums for the coating of pharmaceutical products. If possible, the coating process should not be interrupted for economical reasons. In addition to the geometry of the coater, the drying air and the spraying liquid, the nozzles play a particularly important role in this process. A new nozzle with an antibearding cap (ABC-Technology®) meets the requirement for operating security and improved handling during coating.

  • Doubling spray rates

    New coating arm for tablet coater

    In tablet production, coating processes require a lot of manual operation and experience: The spray arms and nozzles that are used have to be constantly checked, and the spraying process variables require careful adjustment. A new nozzle and spray arm concept now allows you to achieve considerably more efficient processes.

  • Spray with sense

    New nozzle technology ensures better efficiency in tablet coating

    Time and again conventional spray arms cause trouble when coating tablets. They are often difficult to clean and are not easy to inspect. The result is a disruption to the process flow and unnecessarily long set-up times. A new spray arm concept promises to improve this situation.

  • Nozzle for the wood industry

    Professional spraying in industrial wood machining

    Professional spraying in industrial wood machining, especially the production of boards, is gaining increasingly in importance. This is not just because of the increasing cost of energy and raw materials; it is also because increasingly high demands for quality in the manufacture of wooden boards encourage the demand for suitable processes and possibilities, in order to apply liquids as homogeneously as possible onto prepared base materials.
