ULV Cold Foggers/Sprayers
The Ultimate covid19 defense
A cold fogger/ULV sprayer/electrostatic sprayer is a device you can use to fight pest problems both indoors and outdoors. You can also use them to disinfect indoor spaces, as well as get rid of mold and unpleasant odors.
A cold fogger is “cold” because it’s the opposite of a thermal fogger. Cold foggers don’t use heat to vaporize the fogging liquid and turn it into a mist. Instead, they use cold spraying methods, which, in most cases, use high air pressure to spray the fogging liquid out in tiny particles.
Cold foggers usually come either in a handheld fogger or a backpack fogger. The handheld versions are usually cheaper while the backpack cold foggers are easier to carry and therefore more practical.
The most popular type of cold fogger is the ultra-low volume (ULV sprayer). ULV sprayers are considered the same as cold foggers.
How do they work?
Inside the casing of a cold fogger is an electric motor. This is the main part of a ULV fogger since it is responsible for turning the liquid into tiny droplets. The power of the airflow will depend on the power of the motor.
The motors of most handheld foggers are approximately 1-3 horsepower (HP) but vehicle-mounted foggers have much more powerful motors, up to 20 HP. Some cold foggers use oil-based fogging solutions while others use water-based solutions. There are foggers that can be used with both types of solutions. The fogging solution goes in the tank which is either in the body of the fogger or attached to the bottom of the machine.
Most cold foggers work using electricity. This means that you must have a power outlet near the area to be fogged or an extension cord that can reach the target area. Some, however, are battery-powered and others use gasoline to power the motor.
When you turn the fogger on, the motor will pump the fogging solution out of the tank. A blower then sprays the liquid out through a special nozzle located on the front of the fogger. This nozzle pressurizes the air (either by being small enough to confer high pressure or by having a vortex of high-speed air that the liquid is pumped through), turning the fogging solution into a fine mist.
The advantage that ULV foggers have over thermal foggers is that they allow you to control the particle size. On standard ULV foggers, you’ll have the option of setting the particle size from 5–50 microns. You can adjust the droplet size a ULV fogger produces by changing the flow rate of the solution.
This is definitely useful if you need to fog in different areas.
You might want to use smaller particles indoors since they stay in the air longer and can reach smaller gaps and holes in the walls and floor as well as the spaces behind furniture and other tight spaces. Smaller particles are better when you want to kill mosquitoes since the most effective droplet size for this is from 10-15 microns.
For larger insects that live outdoors, you’ll want to use a droplet size at the higher end of the spectrum. Even a small breeze can blow smaller droplets away from the target area. Larger particles, on the other hand, will reach the target area even in slightly windy conditions.
Cold foggers are often set in automatic mode and left to fog an indoor area since there’s no need to have a person operating the fogger (unless they are gasoline-powered). Gasoline-powered cold foggers and thermal foggers should not be run unsupervised due to the fire risk.
The ultimate weapon against Covid19
Some applications includes pest control: mosquito control, bird control, agricultural applications such as grain storage, disinfectant purposes such as hospitals and laboratories, mold control and surface decontamination, all of which makes for the strongest covid19 defense.
Because or the worldwide pandemic Covid19, we are working as fast as we can to fulfill all requests for our great line of products. Soon we will be adding a full line of disinfectant, some of the strongest available for covid19 defense.
“We’ll be using an electrostatic sprayer to disinfect air and surfaces within the cabin, starting with international arrivals into our US subs.”
