Hollow Cone Spray Nozzles

Hollow Cone Spray Nozzles for Fine Mist & Precision Cooling

Create fine droplet sprays with superior penetration and rapid evaporation. NozzlePro hollow cone nozzles deliver efficient cooling, humidification, gas scrubbing, and delicate coating applications with minimal liquid consumption.

What Are Hollow Cone Spray Nozzles?

Hollow cone spray nozzles produce a distinctive ring-shaped spray pattern with a hollow center. This design creates exceptionally fine droplets that are ideal for applications where rapid evaporation, dust suppression, or delicate coating is required. Widely used in cooling, humidification, and chemical processing, hollow cone nozzles provide efficient coverage while minimizing liquid consumption and reducing operational costs.

Unlike full cone nozzles that fill the entire spray pattern, hollow cones concentrate their spray around the perimeter, making them perfect for applications requiring maximum surface area contact and fine atomization.

πŸ”„ Full Cone vs. Hollow Cone

Hollow cone nozzles excel where fine droplets matter: cooling towers, gas scrubbing, humidification. Full cone nozzles excel at uniform saturation: dust suppression, washing, uniform coating. Compare full cone options β†’


How Hollow Cone Spray Nozzles Work

Hollow cone nozzles use a swirl chamber or vane design to spin liquid before it exits the orifice. The swirling motion breaks the liquid into fine droplets, forming a cone-shaped spray pattern with an open center. This unique geometry maximizes surface area exposure, allowing for rapid evaporation and efficient chemical reactions in gas scrubbing applications.

Key Design Elements

  • Swirl Chamber/Vane Design: Spins liquid for centrifugal breakup into fine droplets
  • Ring-Shaped Spray Pattern: Concentrates spray around the perimeter with hollow center
  • Variable Spray Angles: Typically range from 40Β° to 120Β°, depending on nozzle design
  • High Surface Area: Fine droplets provide maximum contact with gases or target surfaces
  • Energy-Efficient Operation: Lower flow rates achieve desired saturation due to fine mist

This design delivers superior penetration and atmospheric residence time, making hollow cone nozzles ideal for cooling towers, humidification chambers, and pollution control systems where every droplet must count.

How to Select the Right Hollow Cone Nozzle

Choosing the optimal hollow cone nozzle for your application involves evaluating several key factors:

  • Define Your Application: Identify whether you need cooling, humidification, gas scrubbing, or fine coating. Each has specific atomization requirements.
  • Determine Required Droplet Size: Finer droplets are better for evaporation and gas absorption; consider your target surface area.
  • Calculate Flow Requirements: Hollow cones often use lower flow rates than full cones for equivalent coverage due to fine droplets.
  • Assess Liquid Characteristics: Evaluate viscosity, chemical compatibility, temperature, and particulate content for material selection.
  • Verify Pressure Capability: Hollow cones typically operate well at lower pressures, reducing pump and energy requirements.
  • Consider Coverage Area: Spray angle selection depends on your target zone size and distance from nozzle.
  • Plan for Maintenance: Select designs with clog-resistant features if using particulate-laden liquids.

Frequently Asked Questions

When should I use hollow cone nozzles instead of full cone?
Use hollow cone nozzles when you need fine droplets for rapid evaporation (cooling towers, humidification), maximum surface area for gas scrubbing (chemical reactions), or delicate coating applications. Full cones excel when you need complete, uniform saturation across an area.
Do hollow cone nozzles require higher or lower pressure?
Hollow cone nozzles typically require lower operating pressure than full cone nozzles to achieve fine atomization. This means lower pump capacity and reduced energy consumption, making them more cost-effective for many applications.
What's the advantage of fine droplets in gas scrubbing?
Fine droplets from hollow cone nozzles create vastly more surface area for gas-liquid contact. This dramatically improves efficiency of chemical absorption and reactions in scrubber systems, cooling towers, and pollution control equipment.
Can hollow cone nozzles handle particulate-laden liquids?
Tangential-flow hollow cone nozzles with larger free passages can handle moderate particulate content. For highly abrasive applications, consider clog-resistant designs or upgrade to tungsten carbide materials. Always use inlet strainers to reduce clogging risk.
How do I optimize humidification with hollow cone nozzles?
Position nozzles for maximum air circulation through the fine mist. Use finer spray angles (40Β°-60Β°) for targeted zones; wider angles (90Β°-120Β°) for broad coverage. Lower pressure settings often provide better energy efficiency in humidification applications.
What materials are best for corrosive cooling applications?
Stainless steel 316 provides excellent corrosion resistance for most chemical and thermal cooling applications. For extreme corrosion or abrasive conditions, consider ceramic or titanium components for maximum durability and longer service life.
