Fog systems are used for a variety of applications, such as improving air quality, suppressing dust, and controlling humidity. Fog systems, when designed properly, can help you meet or exceed air quality standards in your building while delivering your humidity goals. Here at Fogco, we offer a variety of products to suit a wide range of applications in both the commercial and industrial sectors.
How Does a Dry Fog System Work?
A dry fog system works by using an air injection nozzle coupled with compressed air and plain water to create dry fog. The true fog created by this system is similar to what nature produces, meaning the droplets are typically 1-10 microns in size. Fogco’s system has many key features to ensure efficient dust particle removal, as well as up to 99% humidity levels. Our fog systems can produce over 150 lbs of fog per hour and features air nozzles with flow rates at 8 lbs -16 lbs per hour. Our nozzles are also drip free, saving on water costs even if the system loses air pressure. This system also features a control box that allows for on-site adjustments for output and other performance features, allowing you to have the proper settings easily for maximum efficiency.
These type of systems are best used in industries with humidification needs that have height or space restrictions which require the driest fog possible. With controlled humidity, these systems can reduce static electricity, cut down on dust particles and increase the overall speed of production machines.
Fog System Winterization Process
When temperatures drop, there are many things you need to consider to maintain the integrity of your fog system. Preparing your system for winter can prevent unnecessary damage, so make sure to do so before temperatures drop below freezing.
Winterizing a misting system essentially involves removing excess water and restrictions that may cause freezing water to damage the pump and tubing. To accomplish this, take the following steps:
- Turn off the water supply to the mist pump.
- Remove the inlet and outlet tubing from the mist pump.
- Remove the thermal relief valve from the mist pump plumbing.
- Disconnect the bypass hose from the bottom barb fitting on the mist pump’s inlet plumbing.
- Turn on the mist pump. If a low-water safety switch is not included on the pump build, the motor will run and sufficiently empty the bare pump of any excess water within a few seconds. If the pump has a low-water safety switch, the motor will not run because the water supply has been turned off. The inlet solenoid valve, however, will be open and will allow the bare pump to be purged of any excess water by forcing compressed air into the pump’s inlet and outlet ports until all water is gone. This should only take a few seconds. If no compressed air is available, rotate the pulleys on a pulley drive pump or rotate the fan on the rear of the motor on a direct drive pump. Either of these steps will remove excess water from the bare pump.
- Turn the mist pump off.
- Remove the mist nozzles and drain valve(s) from the mist line.
- Using compressed air, blow out the mist lines until no water exists in any open ports. Store the nozzles and drain valve(s) in a dry location until the next season. Soaking the nozzles in heated nozzle cleaner before reinstalling will usually improve the performance of the misting nozzles.
Disconnect the water supply from the filter canister and completely empty it. Use compressed air and blow out the feed line between the filter and mist. This process is a little time-consuming, but it will ensure that no damage is done to the misting pump or the mist tubing during the winter months. At the start of the next summer season, simply connect all the tubing, insert the nozzles, and start enjoying the cooling effects of your misting system for another summer season.
Innovative Solutions for Indoor Climate Control
At Fogco, we have the capability to improve existing humidification systems using outdated equipment or processes. For instance, our misting fans provide enlarged and more efficient coverage compared to static line mist systems. This system is useful for a range of projects in both the industrial and commercial sectors.

I have just ordered a system from you guys, yet to be installed. You recommend removing the nozzles to winterize the system. Is this a good idea, not to install plugs to keep dust from entering the system during the winter months?
You can install plugs to keep the line free of debris but it probably is not necessary because you will be flushing the line at the start of the next summer season.
