Product catalog summary

Introduction
Delavan Spray Drying Nozzles have been industry leaders since 1935, known for their quality, flexibility, and reliability. The company focuses on research and development to address industry challenges with new materials and designs.

High Performance and Durability
Delavan nozzles are durable and wear-resistant, available in materials such as plastics, ceramics, and stainless steel. They offer customization for spray characteristics like droplet size and spray angle, with various swirl chamber designs and orifice sizes.

Technical Expertise
Delavan provides lifetime service and support, using computer analysis to optimize nozzle performance before installation, ensuring efficient spray drying tailored to specific applications.

Atomiser Importance
The atomiser is crucial in spray drying, dispersing feed material into droplets that mix with hot gas, controlling droplet size to affect drying and product recovery.

Nozzle Types

Centrifugal Pressure Nozzles: Use feed liquid pressure for atomization, suitable for high viscosities.
Two-Fluid Nozzles: Utilize gas or steam for atomization, ideal for fine atomization and viscous materials.

Spray Quality and Particle Size
Droplet size is critical, affecting dryer efficiency and product characteristics. Delavan uses the Sauter mean diameter to measure droplet size, aiming for a narrow size range for optimal spray drying.

SDX Product Range
The SDX range includes various nozzles like SDX, SDX III, SDX V, Mini SDX, and Compact SDX, each designed for specific applications, featuring a single inlet design to minimize plugging and ensure uniform particle size.

Conclusion
Delavan continues to innovate in spray drying technology, offering high-quality nozzles that meet diverse industry needs, ensuring reliable performance and customer satisfaction.
