Benefits of Spray Technology of Humidification
Humidity levels in a workspace can become impacted by the weather, the environment, processes, or present temperature. In some instances, only a small amount of water may need to be placed into the air to evaporate to bring the humidity level up in the workspace. Other times, you may need extra moisture to be constantly applied to keep products or processes cool.
Spray technology provides precise control when needed in applications. When connected to humidification and fogging control systems, the nozzles can provide a fine spray based on the schedule that is programmed into the control panel, or when sensors placed in the workspace indicate that humidity levels have reached appropriate levels. Then the system can automatically stop the humidification and fogging process.
Best Uses for Humidification Nozzles & Fogging Nozzles
Humidification nozzles and fogging nozzles are ideal when adding moisture to processes and the environment when air is constantly too dry that it may damage products or operation processes. They may be used in a wide area to allow for the even distribution spread of droplets that have a greater chance to interact with the heat in the air.
The fogging nozzles may also be placed near air inlet areas or ducts to add moisture into incoming air before it enters a process. This arrangement allows for the air to reach relative humidity and temperature levels for the specific application without having the moisture added into the space where the water droplets may impact sensitive equipment.
Fogging nozzles may also be used to remove harmful or toxic gasses from exhaust air. Before the gasses can enter the environment, the nozzles apply water into an exhausted air stream, capturing the toxic gasses and removing them from the air. This process helps clean the exhausted air to acceptable levels to minimize environmental harm.
Common Applications for Humidification Nozzles
Numerous industries can benefit when using spray nozzles for humidification applications. Agricultural and horticultural organizations use spray nozzles to keep vegetables, fruits, flowers, and other plants moist without oversaturating them when the plants are kept in spaces that may be overly dry or enclosed. When vegetables, fruits, and flowers are picked and delivered to retailers, additional humidification nozzles apply water droplets to prolong the freshness of plants to prevent them from drying out on shelves.
Food and beverage industries may use humidification and fogging nozzles when solid, semi-solid, and liquid products require moisture to prevent drying out when undergoing processing. The mist may be applied during specific workstations or when the processed food moves along conveyor belts.
Industries that may have processes that create high temperature levels may utilize nozzles to cool off equipment or to cool off parts or products that have been heated. Drying kilns, distilleries, and curing rooms are a few applications for these nozzles.
Important Factors to Consider When Selecting a Nozzle
A key consideration is that a very fine mist must be created for the right evaporation rate while dealing with low flow rates. When dealing with low water flow rates, there is not enough pressure to produce kinetic energy that allows for the water droplets to be broken up into the desired misting size. Misting and fogging nozzles need to allow for low flow variants while still creating a very fine droplet size that isn't too large for evaporation purposes to prevent unnecessary wetting.
Another important factor is that if low flow rates are present, the fine spray must reach all desired areas in the workspace or process. Since there is not enough momentum from the lower rate of flowing water, the generated mist or fog is not propelled out as far from the nozzle orifice, resulting in a shorter spray length. To address this issue, air atomizing nozzles. With a compressed air current mixing into the water, the resulting fine mix can reach the desired locations.
