Chauvet DJ Nimbus Dry Ice Fog MachineNimbus is a professional dry ice machine which produces thick, white fog that hugs the floor and dissipates without rising. This powerful machine heats enough water to create fog from 10lbs of dry ice to provide 6 minutes of run time. Output and flow are easily controlled, thanks to an adjustable multi level control arm. Dual heaters allow for faster heat up and recycle times. A low water sensor increases safety.
