Rosco ColdFlow – used

The Rosco Coldflow 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 your Rosco Model 1600 (or just about any other Rosco fog machine), and run the fog through the cooling chamber. The fog is chilled below ambient temperature and will hug the ground.

It is well known that the cooler the fog, the better the effect. That’s why, by exposing the fog to the low temperature of dry ice, you can get a great effect.
