Chauvet DJ NIMBUS Professional Dry Ice Machine Creates Thick Low-Lying Clouds That Hug The FloorNimbus Nimbus 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 10 lb 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. Optional Accessory: Nimbus Cart
