How Misting Nozzles are used in Outdoor Misting Systems

People who are aware of the working of outdoor misting systems will know that the misting nozzle is the heart and lungs of a misting system. The function of the misting nozzle is to convert water into a fine mist (measurable in microns) by using high pressure. As the water droplets coming out of the nozzles have to be fine, the holes in the nozzles are made exceptionally small.

When the Misting Nozzleswater gushes through the misting nozzles, it gets vaporized and this process is called flash evaporation. Due to this process, a mist is created that enables the area to become cool and humid. These types of misting systems are widely used in residences as also in many commercial establishments to ward off the oppressive heat of the sun – particularly during summer months. The other important components of outdoor misting systems are the misting fans and mist line systems. The misting fans have proved to be highly helpful in green houses, horticultural areas, livestock cooling, dust control, sporting arena etc.

One of the likely problems when using misting nozzles is that the orifices through which the water passes through can easily become clogged – though misting nozzles have a filtration system to catch fine particles. There are also high quality misting nozzles that come with a double filter system.

The nozzles have to be periodically removed and cleaned as they are prone to clogging. They will however have to be replaced if broken or if they become worn out with age.

When you want to clean the misting nozzles to improve its performance, you should remove them from the line and soak them in a container of a vinegar solution diluted with water. Alternatively you can use mist nozzle cleaners that will also prove effective in loosening any debris.

After the nozzles are left soaking overnight, you can remove them give the heads a light tap to further help loosen the dust particles. A second swirl around in the same solution should completely eradicate any remaining deposits.

When cleaning misting nozzles, never use pins or sharp nails as that will damage the nozzle and render it ineffective. Brushing with a light brush should suffice to remove the clogging.

Misting nozzles made of brass, ceramic and plastic are available in the market. Possibly brass misting nozzle that is completely made of brass will give you reliable performance for many years. The ceramic nozzle may be entirely ceramic or made with brass or stainless steel coating and with a ceramic insert.

The size of the droplets of a ceramic mist nozzle would be as small as 1-3 microns compared to the 7-10 microns of a brass mist nozzle. Because of this relatively smaller water droplet, the required water pressure to achieve flash evaporation is minimized. An added advantage of using a ceramic orifice is that there is less wear and tear than with other materials.

Misting nozzles come in different sizes and angle ranges and are also capable of functioning at varying PSI levels ranging from 30-250.

There is provision for adjustability as some places may need more cooling compared to certain other places. The strength of the water that is forced through the nozzle would obviously determine the quantum of water that needs to pass through the misting nozzle. The misting nozzles can be suitably changed according to the needs.

Uses of a Patio Misting System

Whether you are at work, or play, or simply relaxing, patio misting systems are a revolutionary technology to protect you from sweltering heat of summer months and provide cool comfort in the outer spaces.

Patio misting systems vaporize instantly and cool the air where it is let out. The speed at which the droplets vaporize is however subject to the prevailing temperature in the environment. If the temperature is high then water disperses swiftly. A patio misting system is a veritable boon during those oppressive summer months. There is a wide range of uses for patio misting systems:

Patio Misting SystemsHeat Reduction is the basic application of the system. It saves you, your family members and kids as also your pets from unbearable heat and dehydration. When you use the Patio Misting system during the most uneasy summer season, it reduces temperatures as much as 35 degrees F. The water droplets that are let out absorb the heat that exists in the environment and disperses it. This leads to a considerable drop in the existing temperature.

Patio misting systems can be an economical and highly effective cooling alternative. They

can control the movement of flying insects and keep away wasps, hornets, mosquitoes and all types of flies including spiders. Outdoor misting systems produce fine droplets of water that stick on to these creatures and makes them immobile. This restricts them from flying and repels them from the area that is powered by a mist system. Patio misting systems also keep the entire area free from dust, smoke and other pollutants.

While most people want to enjoy the outdoors during the hot summer days, excessive patio heat often drives many back into the interiors. Hitherto, it was believed that Patio misting systems were a luxury reserved for the richer people, but that is no longer true. All homeowners today have changed their lifestyle and spend a lot of time in their own front open areas and backyards.

Homeowners now create outdoor spaces as extensions of their indoors to enlarge the living spaces. Nowadays, homeowners are using various types of outdoor furniture in their front and backyards. As a matter of fact, they create not only outdoor recreation areas but also outdoor living rooms, outdoor dining rooms, and even outdoor kitchens.

Misting systems are now available in low, mid, or high pressure varieties and the price of each can vary substantially. Low pressure systems run off normal house water pressure, mid pressure involves using a 160 psi (approx) pump, and a high pressure of course requires a rather costly 1000-1500 psi pump. There are, of course, different types of systems and the more expensive option uses a pump which pressurizes the water, resulting in a very fine spray that evaporates.

A well designed misting system can be an amazing addition to any backyard or patio. Depending on your requirements, patio misting systems are available for both home use and industrial needs. They are most commonly used for heat reduction, frost protection, air filtration, dust abatement, odor removal, fire and smoke control.

Keeping Cool with Outdoor Misting Systems

Misting systems are a form of evaporative cooling that can cool any given area through the evaporation of water particles. Our body naturally cools itself through perspiration – as it evaporates, our body is cooled. Evaporative coolers such as outdoor misting systems mimic this natural process, and can effectively cool outdoor areas that are sometimes left at the mercy of the brutal summer heat.

Outdoor Misting SystemsHow do misting systems work? Basically, these systems spray a fine mist a by using a high pressure pump and tubing to force water through tiny misting nozzles that are usually made of brass, ceramic or stainless steel. The nozzle itself has an orifice of only about 5 micrometers – a really small hole (about the size of a human hair) that turns the water into a very fine mist. The water droplets that are produced are so small that that they evaporate instantaneously. This evaporation then cools the surrounding air, lowering it by as much as 35 degrees Fahrenheit in just seconds. Outdoor misting systems can be used for a variety of purposes. They can be installed around the perimeter of patios, where they can turn the area from an unusable hot space in the summer to a more resort-like sanctuary. Other uses include keeping a greenhouse with orchids or other plants much cooler so that they can grow at optimum conditions. These misting systems can also keep family pets and livestock cool and refreshed, preventing them from dehydrating or suffering heat strokes. Outdoor misting systems can also control insects and odors, and are commonly used in zoos and farms.

Outdoor misting systems are extremely popular in both humid and dry climates, and are less expensive to install and operate than traditional air conditioning. Many industrial facilities are choosing to install misting systems in worker break areas, to keep employees happy and refreshed while also lowering heat stress levels and making the work environment safer at the same time.

If you’re looking for a way to cool your patio, greenhouse, livestock, restaurant or bar effectively, then you should consider getting outdoor misting systems.
