Our range of spiral nozzles
Our supplier BETE Spray Systems is a world leading manufacturer of spiral nozzles. We have a lot of experience and knowledge regarding different applications where the spiral nozzle is suitable. We offer customised manufacturing when there is a need for a special material or a particular type of connection.
The spiral nozzle is made in one piece, with a large free passage which reduces the risk of clogging. The spiral nozzle is available in a variety of sizes, flow rates, spray angles and materials. This type of nozzle creates relatively small droplets compared to other types of full-cone nozzles and hollow-cone nozzles.
Suitable applications include quenching, fire fighting, gas scrubbing and evaporative cooling.

The unique spray pattern of the spiral nozzle
The design of the spiral nozzle creates a spray with one or more rings with a higher volume flow and relatively larger droplets compared to the spray between the rings. This type of spray pattern is optimal when the process requires small droplets, e.g. in evaporative cooling, while requiring a relatively high volume flow. This type of spray pattern can also be a very good choice when the spray process is affected by a strong gas or air flow.
Spiral full cone nozzle
- The spray pattern of the spiral nozzle is formed by the fluid shearing along with the turns of the spiral, which produce multiple concentric cones.
- The cones form 2 to 3 bands of relatively large droplets, surrounded by wider bands of relatively small droplets.
Spiral hollow cone nozzle
- The spray pattern is created by the liquid shearing along the spiral, forming a concentric cone.
- The spray is concentrated to the perimeter of the spray cone, which consists of relatively large droplets, whilst a fine mist is created within the cone.
The spray of the spiral nozzle consists of relatively small droplets
Compared to other types of full-cone nozzles and hollow-cone nozzles, the spiral nozzle creates relatively small droplets. It is suitable in many different industrial applications such as cooling, quenching and gas scrubbing.
Choose the right spray nozzle for an optimised spray process
Each type of spray nozzle has a specific flow rate, spray pattern and droplet size. To optimise the spray process, it is important to understand how different parameters affect the choice of spray nozzle and solution.
- What is the function of the spray nozzle and the spray process?Read the full answer
The first step when choosing the right spray nozzle is to define the function and application of the spray process, such as cooling a gas, washing a tank or flushing a conveyor belt. Type of spray nozzle, thus also spray pattern and droplet size, are important to consider in order to optimise the spray process.
- Which droplet size is most suitable for the spray process?Read the full answer
Droplet size is often critical in optimising a spray process. Many processes, such as gas cooling and gas scrubbing, depend on exposing the maximum total liquid surface area. The liquid then needs to be distributed in a large number of small droplets to create as much total surface area as possible. Other spray processes ...
- What surface should the spray cover? How should the nozzle be positioned?Read the full answer
The position of the nozzle over the target (D) and the area to be covered by the spray (B) are important to know in order to choose the right spray angle (A). The spray angle is measured near the nozzle orifice and the droplets are immediately affected by external forces such as gravity, air and gas flow.
- Desired flow rate? Available pressure?Read the full answer
Desired volume flow depends on the specific spray process. Most spray processes have general rules of thumb for flow ranges, but in many cases on-site testing is needed to achieve the right results.
- What type of liquid is used in the spray process?Read the full answer
A liquid's specific gravity, viscosity and the presence of particles affect the spray characteristics of the nozzle.
- Are there external factors affecting the nozzle spray?Read the full answer
Sometimes the spray is affected by external forces such as process gas flows, air flows or wind.
- Which material is most suitable for the spray process?Read the full answer
Listed below are a number of factors that should be considered when selecting materials for a specific nozzle. An incorrect choice of material is likely to affect the performance and life of the nozzle. We are happy to help and advise on which material is most suitable in your ...
- What are the benefits of an optimised spray process?Read the full answer
There are many factors to consider when selecting a nozzle for a specific spray process. An optimised spray process can make a big difference, contributing to: improved product and process quality increased production and reduced time for unplanned stops reduced maintenance costs lower operating costs by reducing the use of ...
