MDG is a company globally recognized as the leader of the fog/smoke production industry. We design and manufacture the most reliable fog generators since 1980. Safe, non-toxic fog of overwhelming intensity can be generated and are therefore perfect for use in training fire fighters. They are able to fill large areas quickly and maintain 0 visibilities as long as needed for SCBA training and testing, ventilation procedures, and acclimation to smoke/fire conditions. Due to the unique nature of MDG Fog production, the fog perfectly simulates conditions produced in actual fire situations. It is the perfect tool for testing light sensitive automatic fire warning systems. The MDG system is able to create large amounts of fog outdoors to simulate gas clouds for hazardous materials training.
