The Rosco Coldflow Module is an accessory for standard fog machines that converts liquid carbon dioxide (LCO2) to dry ice. The dry ice cools a uniquely designed aluminum extrusion that is capable of converting large volumes of fog into dense low lying fog. The unit can create a wide range of low lying fog effects from a continuous layer to a gigantic cloudburst.
By using LCO2, the Coldflow is far more efficient than more conventional means for creating a low-lying fog. The unit actually uses the LCO2 to create dry ice inside an aluminum chamber. You then can use almost any Rosco fog machine), and run the fog through the cooling chamber. The fog is chilled below ambient temperature and will hug the ground. Attached to the unit is a 7' metal hose for connection from the Coldflow to an optional LCO2 tank (available elsewhere).
Great Effects Without Dry Ice
Coldflow eliminates all of the problems associated with using commercial dry ice -- finding a source, transporting, handling, storage and the need to limit fog to short effects. Liquid carbon dioxide is commonly found almost anywhere. It is easy to handle and does not require any special storage.
Long Lasting Effects
50 pounds of dry ice will give only a 15-minute effect when dropped in hot water; a comparable tank of LCO2 will last for hours.
The remote control activates Coldflow. The remote has three easy-to-read LEDs. One of these indicators is for ON/OFF, the second illuminates while the unit is cooling (about ten minutes) and a third indicates when Coldflow is ready for operation.
