Misting FAQs

What is the difference between a misting system and a fog system?

The terms misting system and fog system are generally used interchangeably. In some instances, the term fog system may be used to describe a system that is designed for special effects. However, a misting system and a fog system are simply two different terms used to describe the same thing.

How do misting systems work?

Misting systems are most commonly defined as a series of specially mist nozzles placed in a line around the perimeter of an area. When connected to a high pressure misting system pump, water is forced through the specialty nozzles and quickly atomized to droplets as small as 5 millionths of a meter (5 microns).

Misting systems will produce billions of tiny droplets every second. If these droplets are introduced into an outdoor area, they quickly evaporate. This process of evaporation requires energy to be completed. The energy is taken from the air in the form of heat. The result is a temperature reduction of up to 35 degrees Fahrenheit, depending on the ambient temperature and the relative humidity of the air. This method of temperature reduction is the most common use for all misting systems.

When misting systems are placed inside an enclosed area (such as a greenhouse), the billions of droplets that are produced will initially provide cooling as the droplets evaporate. However, if the air exchange is limited, the misting system will continue to increase the humidity level within the structure. Humidity levels as high as 90+% are possible. This unique characteristic of all misting systems makes them ideal for both outdoor cooling and humidification.

What components are needed for a misting system?

The required components for a misting system include tubing, specialty misting system nozzles, and a water supply. Additional components may be required for a specialty use of the misting system or to improve its performance.

The most effective method of improving the performance of a misting system that only utilizes line pressure is to add a high pressure pump. By increasing the pressure of the misting system to 1000 psi, the misting systems performance can be improved by up to 300%. This is accomplished because at these higher pressures, the specialty misting system nozzles are able to atomize the droplets from 1/10th to 1/50th the size of a line pressure system. These smaller droplets will not only evaporate quicker and provide much better cooling capabilities, but the system will produce 40 to 50 times the number of droplets which will further improve the effectiveness of the misting system.

How do I decide which type of misting system I need?

Although the basic requirements for all misting systems are similar, there are some specific differences that should be reviewed.

If the performance of the misting system is the most important factor, a 1000 psi high pressure system is recommended. All commercial and industrial applications will utilize a high pressure version of a misting system.

These pumps required for a high pressure misting system can vary in size, design, and cost. Speaking with a qualified manufacturer will help determine which type of pump is best for any given application.

In addition to the pump options, there are several different types of misting system tubing that can be used. Some applications are better designed utilizing flexible tubing while others need rigid tubing. The specific application and the misting system design will usually help determine which type of tubing is best suited for a given need.

The last consideration is the misting system nozzles. These are available in a variety of flow rates to allow a misting system to be tailored for any application. Whether the system is used to create high humidity in a commercial environment, or just to cool down a small residential patio, the various misting system nozzles will allow a perfect fit for any environment.

Do misting systems require maintenance?

As with any piece of equipment, there are some important maintenance issues to consider. The heart of any misting system, the pump itself, can last for many years as long as they are taken care of. The primary maintenance for a misting system pump is to check the oil and change it each year.

The only other maintenance consideration for a typical misting system is to periodically clean the nozzles and to drain the system each winter to prevent freezing.

With these simple steps, a quality misting system can last for many years to come.

Do I need to do anything to my misting system during the winter?

To prevent freezing and damage to the pump or the misting system, all of the misting system nozzles should be removed. The misting system line, the misting system pump, and the filtration should be drained.

How much do misting systems cost?

A misting system can cost anywhere from a few hundred dollars to a few thousand dollars depending on the size, quality, the specific requirements of the application, and whether the misting system will be installed by a professional contractor or installed by the homeowner/business owner. It is recommended that a consultation and misting system design be provided from a qualified manufacturer with at least 10 years experience in the industry before any purchase decisions are made. This will allow the consumer to have the benefit of all the details and system requirements before making such an important decision.

Can I install a misting system myself?

Some misting systems are designed for the ‘do it yourself’ consumer. These misting systems are easy to install and typically take between two and four hours to complete.

If a professional installation is required, a licensed and bonded contractor should be used. This will typically add about 30% to the overall cost of the system but it will provide for a quality installation from an experienced contractor.

How do I know if the manufacturer is able to provide the system I need?

Because the misting system industry is a small, specialty business, the best method of sourcing the products is to rely on longevity and experience. Many companies come and go, but few have the resolve, the knowledge, and the passion to stick around for the long term. Fogco Systems, Inc has been in business since 1989 providing high quality systems for residential, commercial, and industrial applications. With over 75 years combined experience in this industry, there are few competitors that have the level of experience or understanding that is provided with every misting system designed and sold by Fogco Systems, Inc.
