The fog machine is device that emits a dense vapour very similar to smoke or fog. The fog is created by vaporizing either a glycerine or water and glycol based fluid. What happens is the fluid is pumped into a heat exchanger that is kept hot enough to vaporize the liquid, this is known as flashing. As it vaporizes it will rapidly expand and is forced out of a nozzle into the outside air. As soon as it hits the air it forms a grey aerosol which we associate with fog or smoke. London Lighting Hire carries numerous models of fog machines that utilize many different technologies but they're basically ...
... just a variation of the process mentioned above.


There are a few factors you should consider when looking to purchase a fog machine as they can vary considerably in price. First, is the amount of time it takes to warm up the heat exchanger. This can be a crucial depending on what your use for the machine is. If it's going to be used for numerous short intervals you'll definitely want to invest in one that heats up quickly so that you don't have to wait. Otherwise, if you only plan on running it continuously than you'll probably be able to get away with one that has a slower warm up time. Another important factor to think about is the amount of smoke that the machine is capable of putting out. This is usually measured in metres cubed per minute and can vary from about 200m3/min all the way up to 5000m3/min. A few extra features that some of the fog machines at London Lighting Hire offer are output and density control for the amount of fog released and a timer to control the duration that the machine runs for.
