Ultra low volume (ULV) fogging machines.
ULV fogging machines are cold fogging machines that use large volumes of air at low pressures to transform liquid into droplets that are dispersed into the atmosphere.
Indoor Air Quality Control
What is air quality control?
How is it done?
Thermal foggers, as the name suggests, use heat in the fogging process. Thermal foggers use heat to vaporize a fogging solution and spray it out in form of a fog. Thermal foggers are equipped with a heat barrel that is preheated to high temperatures using either a propane gas or electricity depending on the type of a fogger. The fogging solution is in a liquid form, and when it gets pumped into the heat barrel, it instantly is vaporized. This allows the fogger to produce large count of particles in extremely small size, which all together forms a dense cloud of fog.
What Are the Benefits of Indoor Air Quality Control?
The usage of both thermal and ULV foggers is similar in many ways, as both devices are generally foggers or misters and are used to spray out either a water or oil based fogging solutions. Both types of foggers are used in such applications as insect control, odor and mold control in indoor areas, for disinfection, to apply pesticides to plants, getting rid of pests in warehouses and other similar uses. Besides these places, there are other areas, where thermal foggers are better suited than ULV foggers and other way. Thermal foggers have advantage of producing particles in smaller size than ULV foggers and the fog is also easily visible, which makes them better in such applications as:
Mosquito and insect control. Because of small droplets a thermal fogger produce, they are good for mosquito and other smaller insect control. For mosquito control the best droplet size is from 5-20 microns, and most thermal foggers will produce particles in this range. Controlled outdoor fogging. Because fog that a thermal fogger produce is thick and easily visible, you can more easily control the direction of fogging. This will make an outdoor fogging more controlled, because most ULV fogging devices produce hardly visible fog.
Fogging obstructed areas. Because of small particle size, fog produced by a thermal fogger can reach in very small places such as floor gaps, cracks in walls and similar places indoors, or into thick bushes, long grass, high tree tops and other hard to reach outdoor places. ULV foggers in opposite do not use extensive heat in fogging process, so they can be used indoors without fire risks. Also, allow to adjust particle size, so they can be used in more applications than thermal foggers. ULV foggers are used:
In any indoor place. As mentioned above, ULV foggers use cold fogging techniques, so they are safe to use indoors.
For odor control and disinfection. ULV foggers are often used to disinfectant houses and large warehouses as well as control unpleasant odors in such areas. ULV fogger can be left to work automatically and there isn’t need for a person to operate the fogger all the time as with thermal foggers.To get rid of molds. ULV foggers are also used with special chemicals to get rid of molds in indoor areas. On plants and greenhouses. Because ULV foggers allow to adjust particle size, they can also be used outdoors or in greenhouses to spray different solution on plants.
Indoor and outdoor pest control. ULV foggers are the best pest control method for indoor areas, however, they are also used outdoors, for example to control mosquitoes. Although ULV foggers cannot produce such small particles as thermal foggers, some ULV foggers can produce particles from 5-20 micron range, which is effective for mosquito control.
