Fog machines work by heating up the ’fog juice’ (often a mix glycerin or glycol mixed with water) and thus produce fog. Higher end fog machines have heating systems that heat up at faster rate. The Elation 800w Portable Fog Machine, for example, heats up in only 100 seconds. Fog machines with fast heat up feature stainless steel or nickel-aluminum alloy to ensure rapid and efficient heat transfer. Higher end fog machines will also have DMX universes so that they can be controlled remotely by a lighting controller and integrated into a larger lighting system. In addition to rapid heating-up, higher end fog machines, will feature fine tuned fan systems that are nearly silent and are ideal for noise sensitive events.
Low end and high end fog machines are also differentiated based upon the quality of the fog they produce. High end fog machines produce fog with a perfect haze of fine-particles that is also low in residue and thus requires less cleaning than a lower end fog machine. The dense and low hanging fog of dry-ice fog machines has long been the industry standard for fog. Dry ice fog machines, due to the difficulty in handling dry ice, have been replaced with fog juice based fog machines. Therefore machines that can replicate dry ice fog, like the Elation Low Lying Fog DMX Cooler, are often more expensive because they require additional technologies to ensure that the fog is adequately cooled after it is heated so it can hang low.
