Hollow Cone Nozzle
Tangential Hollow Cone Nozzle
A tangential hollow cone nozzle delivers a ring-shaped spray pattern that covers a circular footprint evenly, which is essential when cooling or scrubbing gas streams in ducts, towers, or scrubbers where uniform droplet distribution across the full cross-section is required. This CNSS hollow cone range operates at 60° to 120° spray angles and 0.125 to 145 L/min at 3 bar, making it suitable for gas washing, evaporative cooling, and chemical processing where consistent droplet coverage prevents hot spots and ensures efficient contact. The design features large unobstructed flow passages to reduce clogging risk in dirty or particulate-laden streams.

Key Benefits
What This Nozzle Gives You
- Ring-shaped spray pattern ensures even droplet coverage across the full cross-section of a gas stream
- Wide spray angle range from 60° to 120° allows coverage in tight or variable duct geometries
- Large unobstructed flow passages minimize clogging in dirty or recirculated water systems
- Uniform distribution of small to medium droplets improves heat transfer and gas absorption efficiency
- Available in multiple materials to match chemical and thermal duty in scrubbing and cooling service
- Free trial samples and 10 day sample lead time for testing in actual process conditions
Application Scenarios
Where It Is Installed
- Gas scrubbing systems where fly ash and particulates must be captured in a uniform spray curtain
- Cooling towers and spray ponds requiring evaporative cooling with even droplet distribution
- Metal treating lines using water or chemical sprays for surface conditioning in enclosed chambers
- Chemical processing units where gas streams need consistent contact with liquid reagents
- Brine spraying applications where salt-laden water must be atomized without clogging
Who It Is For
Buyers Who Specify It
- Plant engineers maintaining or upgrading gas scrubbing and cooling systems
- Scrubber system integrators specifying nozzles for gas cleaning and emission control
- Cooling tower operators dealing with uneven cooling or clogging issues
- OEM machine builders integrating nozzles into chemical or metal treating equipment
- Maintenance teams replacing clogged or worn nozzles in high-particulate environments
Problems It Solves
What It Fixes on the Line
- Uneven droplet distribution that leaves dry zones in gas streams, reducing scrubbing efficiency
- Clogging in narrow orifice nozzles due to particulates in recirculated or dirty water
- Inadequate coverage in ducts with irregular or narrow cross-sections
- Hot spots in cooling towers caused by poor spray pattern uniformity
- Frequent nozzle replacement due to internal blockage in abrasive or high-solids streams
Technical Features
How It Is Built

Comparison
How It Compares With the Alternatives
| Flat fan nozzle | A flat fan delivers a linear spray, suitable for moving surfaces like belts or strips, but cannot cover the circular cross-section of a duct or tower |
|---|---|
| Full cone nozzle | A full cone covers a circular area with solid impact, but may not provide the same uniform ring distribution for gas scrubbing or cooling |
| Spiral nozzle | A spiral nozzle handles solids better due to external vanes, but its cone pattern is not optimized for uniform ring coverage in gas streams |
| Hollow cone nozzle with filter | The filtered version protects against clogging but adds a strainer that may require cleaning; the standard version is better for dirty or high-solids streams |
Use Guide
Fitting and Running It
- Confirm the target duct or tower diameter and standoff distance before selecting a spray angle
- Choose a spray angle between 60° and 120° based on the available space and required coverage width
- Ensure the flow rate matches the system’s pump capacity and pressure at the nozzle
- Match the body material to the chemical and thermal conditions of the process fluid
- Install the nozzle with the tangential inlet aligned to the flow direction to maintain swirl
- Inspect the orifice for wear or blockage if spray pattern becomes uneven or flow drops
