VCN™ Variable Coating Nozzle™ Delavan

VCN™ Variable Coating Nozzle™ Delavan offers total control for demanding applications where control over a viscous media is required, including those in the pharmaceutical, food, and engineering industries. The VCN’s design allows the width of the spray, the atomizing air, and the flow of the liquid all to be controlled independently and remotely. The specially designed Air Cap reduces the build up of product, enabling longer production runs with reduced maintenance.

Total Droplet Control
• Consistency – Each VCN™ produces the same droplet spectrum throughout the run, every run.
• Accuracy – Our technical expertise guarantees a closely controlled  droplet spectrum.
• Adaptability – The VCN™ Unit is available in sizes ranging from 0.8 to 2.5mm and will cope with a wide variety of coating media

Quality Assurance & Certification

Inspection
• All parts are manufactured on our world class CNC machinery and inspected at every stage of manufacture in our ISO9001 manufacturing facility.
• Every complete unit is tested and individually serial numbered prior to dispatch.

Characterization Certificate
• Full Material Traceability is ensured throughout manufacturing process.
• Droplet size characterization data can be provided on a Spray performance and velocity

Liquid Shut Off
• The flow of the liquid can be shut off automatically to avoid dripping.
• A special shut off sealing kit is available for use with low viscosity liquids

Variable Spray Width
• Optimizes the wetted area.
• Minimizes the risk of localized over-wetting.
• Maintains the optimum internozzle distance for all common coating media.
• Remotely controllable and is easy to adjust either manually, via a pressure regulator, or automatically from a control panel.
• Setting is uniform between nozzles and consistent each time the nozzle is operated – ideal for repeatable, automatic control in a  multi-nozzle configuration.
• Low air consumption minimizes running costs.

Cleaning & Service
• Special Anti Bearding Air Cap design reduces build up of coating material during the run.
• Compact aerodynamic design reduces disturbance of the rotating air in the drum, giving more coating media on the product, resulting in less cleaning and wastage.
• Rapid strip-down and reassembly saves time between batches.
• Push-in connectors eliminate the need for special tools.
• Clearly marked ports speed up reconnection and reduce operator error.
• All parts can be ultrasonically cleaned.
• New design avoids entrapment of dirt and organisms.
• All wetted metal parts are 316 Stainless Steel.
• Seals can be provided in a number of FDA approved materials to suit various coating media.
• No additional parts required for inter-connection – comes complete with  push-in connectors.
