A low-lying fog machine, often referred to as a fog chiller, ground fog generator, or low fogger, is designed to produce fog that remains close to the ground. These machines create a dense fog that does not rise, making them ideal for various applications. They are commonly used in touring and fixed installations, including concerts, weddings, theaters, discos, operas, dances, magic shows, circuses, theme parks, television and film productions, sports events, special effects, and military or fire training.
There are several types of low lying fog machine, according to the way they achieve the effect there are at least three types:
A dry ice machine is a type of low fog machine that uses dry ice to create fog. It generates low fog by spraying hot water onto the dry ice. One of the greatest advantages of this method is its ability to produce long-lasting, thick, and dense fog that adheres well to the ground. This effectiveness is due to the extremely low temperature of dry ice, which is -78.5 degrees Celsius, combined with the high molecular weight of CO2, making it heavier than air.
However, there are some disadvantages to using a dry ice machine. The cost of dry ice can be significant, and handling it requires caution due to its extremely low temperature.
As we all learned from physics, the cooler air sinks and warmer air rises. The regular ice machine takes advantage of this theory, the fogs go through the ice and cools down, then it sinks to the ground and generate the low lying fog.
The main advantage of this type of machine is the accessibility and low cost of regular ice, especially when compared to dry ice. Additionally, the machine itself is relatively inexpensive. However, a disadvantage is that the fog produced does not adhere to the ground as effectively as that generated by dry ice machines.
An ultrasonic low fog machine consists of two main components: a fogger and an ultrasonic unit. The fogger generates fog that mixes with atomized water, making it heavier so that it adheres better to the ground when released from the machine.
One of the key advantages of this type of fog machine is its ability to produce a continuous, long-lasting low-lying fog, especially when compared to the quickly melting dry ice or regular ice. It operates using only fog fluid and water, making it an excellent option for events requiring extended periods of low-lying fog. Additionally, the consumables are inexpensive and readily available. However, a disadvantage is that the ground adherence of the fog is not as strong as that produced by dry ice machines.
Low-lying fog effects are among the most popular in various settings, ranging from personal gatherings to large-scale outdoor events. By creating a cloud-like atmosphere on the ground, these machines evoke feelings of grandeur and romance. Whether you're a DJ, wedding planner, or special effects professional, a low fog generator can elevate any stage or event. The applications for low fog generators are virtually limitless, limited only by your creativity. Below are some common use cases.
One of the most popular uses for low fog generators is during the couple's first dance. Imagine a bride in her beautiful gown and the groom dancing on a cloud of fog created by the CREEPER series low fog machine. This enchanting moment is sure to become one of the couple's most unforgettable memories, adding a magical touch to the entire wedding celebration.
Low fog generators are also frequently used in theater productions to create a ground cloud atmosphere that complements various scripts. Filling the stage with fog during dance scenes can make performers appear lighter and enhance the overall visual experience.
For magicians, ground fog adds an element of mystery to their performances. It not only enhances the illusion but can also be used to conceal props during tricks, creating a more captivating experience for the audience.
To attract visitors, many restaurants and parks are designing artificial lakes or water features. When paired with a low fog generator, these areas can be enveloped in mist, creating an impressive setting for guests to relax, enjoy a meal, or sip coffee.
In professional settings, low fog generators are commonly requested to create ground clouds that enhance the stage design. During music concerts, the flowing fog beautifully complements the singers' performances, creating a captivating visual experience.
Additionally, low fog effects are popular for events like Halloween, where they help to create an eerie and atmospheric setting.
Using a low fog generator can create stunning effects, but it can also be challenging without the right skills. Here are some tips based on our experience to help you achieve the best results:
Even a light breeze can significantly impact the low-lying fog effect by dispersing it quickly. For optimal results, it's best to use the fog generator indoors where there's no wind. If you're using it outdoors, consider having multiple units on hand to combat windy conditions, and try to position the generator near a wall or other shelter to contain the fog.
Before using a low fog machine or any type of smoke or haze machine, check the venue's smoke alarms. Different types of detectors, such as smoke-activated or photoelectric detectors, have varying sensitivities, so it's important to ensure that your fog effects won't trigger them unexpectedly.
Temperature is a crucial factor that can greatly influence the effectiveness of low fog. Generally, warmer weather enhances the low-lying fog effect. Cold temperatures can significantly affect regular ice machines (fog chillers), so consider this when planning your setup.
For dry ice low foggers, it's important to account for heating time, which typically takes at least 30 minutes (depending on the water tank capacity). It's advisable to start heating the machine at least half an hour before you intend to use it.
Both water-based fog generators and fog chillers require fog fluid. We recommend using the original fog fluids provided by the manufacturer, as fluids from different suppliers can vary significantly. Using inappropriate fluids may lead to blockages and performance issues with your foggers.
