How Mist Systems use water

By January 20, 2014February 16th, 2020No Comments

Water is a unique and incredibly diverse resource. It is the only substance on the planet that has the ability to naturally exist as a solid, a liquid, or a gas.

Consequently, water has varying properties depending on the state it is in.  Misting systems take advantage of both the liquid and the gas properties of water to achieve effective dust and odor control, to reduce ambient temperature in a cooling application, and to increase relative humidity levels in a humidification application.  When water is atomized into tiny micron sized droplets and effectively dispersed into the air, its properties are magnified.


As a liquid, water has the ability to absorb and be absorbed by other compounds. If properly dispersed in large quantities, water droplets can absorb individual dust and odor particles and completely remove them from the air in a process known as adhesion. This allows water to be used as a simple yet effective method of dust and odor control.  When combined with the added capability to inject the fog into a strong air stream, as is done with our Spraystream product range,  Large area and outdoor dust and odor control is easily achieved.


When water evaporates to a gas, its physical properties change.  The flash evaporation of the liquid to a gas absorbs energy from the air in the form of heat which results in significant reductions in the ambient temperature. Because water has the ability to absorb more heat for each degree of temperature reduction then most other substances, water evaporation is an ideal method of outdoor cooling.

This capability is the basic concept behind all misting systems.  The primary difference between misting system manufacturers is the appropriateness of the mist system design and how well the fog nozzles will atomize the water droplets.  Fog Fogco, it is also a matter of whether the system design includes the added benefit of our ‘air assist’ fans in the Revolution product range.

When water is evaporated and the air exchange is limited, the relative humidity will increase. By controlling the amount of moisture and the air flow, any relative humidity level can be artificially created an precisely maintained.

This is how humidification systems are designed.  They utilize the same basic components of a cooling system, but they are designed to allow build up of the moisture in the air to achieve a required level of humidity.  Humidification systems are typically used in greenhouses and grow chambers and they are also useful for a number fo different industries that require a humidity level above 50%.  this would include textiles, wood working, paper storage, and printing facilities.

Once the air becomes saturated and can no longer absorb additional moisture, 100% humidity is achieved and the water will stay in its liquid state. Micron sized droplets of water will suspend themselves in the air creating a natural fog effect. When properly applied, this saturation point is used to create unique and dramatic landscape special effects.

Fogco’s specialty designed systems utilize customized high pressure pumps, fittings, and components to take advantage of these natural properties of water and create solutions for many different industrial, commercial, and agricultural applications. Our experienced design staff can help you find the most appropriate solution utilizing the power of fog and the natural properties of water.
