About: Rosco Coldflow Low Laying Fog Module

The efficient way to create low-lying fog on demand.

  • More efficient than conventional means.
  • Can be used with almost any Rosco fog machine.
  • Easy manipulation.
  • Remote control included.

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 Alpha 900, Delta 3000 and Model 1700 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. Coldflow eliminates all of the problems associated with using commercial dry ice. These problems included 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. Whereas 50 pounds of dry ice will give a 15-minute effect when dropped in hot water, a comparable tank of LCO2 will last for hours.

Best results will be achieved when the Rosco Coldflow used with any Rosco fog machine plus Rosco Stage & Studio Fog Fluid. Stage & Studio is specifically designed to help create fog that will lie lower and accept the lower temperatures and other changes created by the Coldflow.

A remote included as standard equipment 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 tells you when Coldflow is ready for operation.

Attached to the unit is a 7' metal hose for connection from the Coldflow to a LCO2 tank.
