Mission: to provide the industry with the finest Haze, Fog and Low Lying fog generators. 100% duty cycle, the lowest fluid consumption, the most quiet, and the most reliable. The best performance, just like yours. No compromise. MDG is a company that manufactures a complete line of the most reliable and durable fog generators for the entertainment and industrial market since 1980. The products range from a discreet haze to an overwhelming effect of pure white fog, all used in most entertainment venues: Themed Amusement Parks and Attractions, Special Effects for films, Television Studios, Performing Art Centers and Theatres. MDG products cover every aspect of the Industrial sectors such as Fire Fighters and Military personnel training. MDG uses CO2 (or most inert) gas as a propellant and Automatic Purging System™ (APS™). This system purges the heating module after the first heating cycle and after every emission of fog preventing residual build up and clogging. MDG also created a unique hazing system in its ATMOSPHERE Series™ generators. The MDG NEUTRAL FLUID, an extra refined mineral oil-base fog fluid, is heated to a precise temperature and propelled by inert CO2 gas to exponentially reduce particle size, thereby producing non-stop haze with the longest "hang time" in the industry, while dramatically reducing both fluid consumption and residue.
