The NimbusTM dry ice machine creates a dense, white fog that hugs the floor and evaporates without rising. This powerful machine heats enough water to make fog from 10 pounds of dry ice for a total run time of 6 minutes. Thanks to an adjustable multi-level control arm, output and flow may be readily regulated. Heat-up and recycle times are sped up with dual heaters. The use of a low-water sensor improves safety.
