As general, Water Mist nozzles are designed to obtain spray pattern based on more than 99% of very fine droplets, with single droplet size less than 1000 microns.

 

But this is only a basic standard definition of Water Mist, because many of these nozzles can generate very small droplets, in the range between 5 to 50 microns.

 

There are many applications where Water Mist nozzles are a key factor for the best final result, such Fire Protection systems, Explosion Protection systems, Lumber Drying, Cooling and Humidification systems.

 

Thus a good WM nozzle design and material quality, together with an expert technical support for the customer, make the difference between the minimal and the best process result.

 

 

We, in Spraytecs Technologies Ltd, design and manufacture water mist nozzles in both High Pressure (> 50 bar) and in Low Pressure (3 to 12 bar) according to your requests, specifically designed for your application, with an approach highly collaborative towards your technicians from the first contact.

 

 

 

We can accept orders also for small quantities.

Here below are listed the Water Mist Spraytecs standard nozzles for applications in Low Pressure and High Pressure  (LPWM and HPWM), with their technical data.

 

 

The water mist nozzle Spraytecs WM18O027 is designed for special applications, where the spray pattern must be directional and condensed in little spaces and at high distance from the nozzle. 

Water mist nozzle 1/8 Spraytecs 10 degrees

Main application is in the market of Fire Protection, which uses as a barrier for water protection of accesses and curtains of theaters, such as strengthening and defense of fixed and mobile mechanical protection curtains, cable ducts, chimneys, crevices and loopholes. All the mentioned cases have problems that only a specifically designed nozzle solves effectively. Where the low cost and water consumption is negligible if compared to a classical barrier protection with a blade of water to flood.

 

Even the uses of this Spraytecs water mist nozzle for the purpose of general risk reduction, such as cooling quote in areas subject to concentrated and abnormal overheating, can prevent fires and explosions, and thus exclude the need for action of the complete plant shutdown. Intervention that sometimes causes significant collateral damage.

 

It can be used both into Low Pressure  and into High Pressure water mist systems, resulting in different strategies of intervention and number of nozzles used.

 

Spraytecs provides the data sheets in order to use this new component to obtain a smart protection Water Mist Curtain, Economical and Effective.

 

The nozzle Water Mist WM18O027 is available in stainless steel AISI 303, AISI 316L and Hastelloy C276 for special applications in corrosive environments.

 

For the realization of convenient and low visual impact, it is proposed a complete Water Mist Curtain Spraytecs installation kit composed of stainless steel tubes diameter 12 mm or 25 mm and stainless steel fittings to configure the Water Mist Barrier tailored to your installation.

 It is also strongly recommended the use of Spraytecs suitable filters for these water mist nozzles that have internal water passages extremely low.

 

The average size of 90% of the droplets present in the spray (DV90) is less than 250 microns to 3 bar (low pressure), while at 100 bar (high pressure) have a size less than 100 microns.

 

Here below performances, technical data sheets and aid in the design of systems with this special water mist Spraytecs nozzle, for the most appropriate use in your installation.

 

 

 


The same nozzle, with pressure values very different (low or high pressure) generates a conical full spray of different angle, a factor to be considered during the design phase of the system.

 

At a water pressure of 3 bar the spray angle is 6°, but at 100 bar it becomes of 15°.

 

 

 

 

  

                             

                                                                                      Here above is shown a test phase during the development of a special

                                                                                      water mist application.

 

 

 

 

Concept of Spraytecs water mist curtain to protect a theater curtain and the surrounding décor.

 

 

 General considerations on the distribution of a directional nozzle water mist at low pressure and the distribution to be considered at the design phase in the following figure:

Water Mist Spraytecs directional nozzles WM18O027 used at Low Pressure (3 bar) in order to obtain a water mist curtain or as general to protect a restricted and deep area.

 

        

The water mist curtain must be correctly sized and integrated with few nozzles positioned transversely, to ensure a complete partitioning by water mist. Schemes are available to suggest right solutions on the basis of heights and widths of accesses to be protected, in addition to the Spraytecs kit components (pipes and fittings stainless steel) for quick installation.

 

 

Dimensional and performances data sheet are shown in the below tables. 

 

 

 


 

Also water mist nozzle Spraytecs WM14O109 has been designed for special applications, where the spray pattern must be directional and condensed in little spaces and at high distance from the nozzle. 

 

This nozzle has higher flow rate and maintain a correct direction to droplets for a longer distance, with excellent performances in various fire hazard contexts, where the mist action must be concentrated.

 

 

The water mist nozzle WM14O109 is suitable for water mist applications at low pressure, starting by only 3 bar of water pressure (Dv90 < 300 μm)

Here below is shown the performance radial distance of spray pattern for  firefighting systems designer convenience:

 


 

 

 The water mist nozzle Spraytecs WMMCQ has a compact, flat body where the nozzle aesthetics and small dimensions are important.

 

 

  

 

 

 

 

 


  

 

The water mist nozzle Spraytecs WM18L and WM18M has a miniaturized, flat body suitable when nozzle aesthetics, small dimensions are critical and performances must to be superior, to give fine droplets and uniform full cone shape.

 

 

 

 

The water mist nozzle WM18N115 is suitable for water mist applications at low pressure, starting by only 3 bar of water pressure (Dv90 <370 μm @3 bar, Dv32 <100 μm @3 bar)

At a water pressure of 100 bar, nozzle WM18N115 droplets size decrease (Dv90 < 150 μm @100 bar,  Dv32 <45 μm @3 bar)

 

 

 

Spraytecs WM18L and all our miniaturized nozzles can be installed with this commonly available tool (shown below on the left):

                           

 

 


 

LOW Pressure WaterMist nozzles, for firefighting systems (and other industry processes)

 

 

The water mist nozzles Spraytecs WM12X, WM127 and WM12Z are compact, multi-head nozzles suitable for many contexts in fire-fighting systems, where aesthetics, small droplets and body dimensions  are important and performances must to be great, to give fine droplets and uniform full cone shape to assure the correct water density during fire alarm discharge.

 

They are available in different models for all hazard contexts, for LOW Pressure firefighting systems (LPWM) and for HIGH Pressure firefighting systems.

 

Their typical spray angles range is from 150° to 180° degrees, with different flow rates.

 

Our Low Pressure water mist nozzles are oriented to save energy and costs in all firefighting system layouts, because they work and make fine droplets starting by the very low pressure of 3 bar!

 

The above feature in water mist firefighting systems consent to use smaller and less expensive pumps, and/or directly the local available water grid pressure (in some countries this design solution have to be approved by the local firefighting authority).

 

Typical applications of these nozzles are not only for firefighting systems, but they are great also in air and gases cooling, air and gas cleaning, vessels cooling, dust control, humidification processes and others.
