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 aluminium chamber. You then can use your
Rosco Model 1600, 1700, 1900, Delta 3000 (or just about
any other 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 22kg of dry ice will
give a 15-minute effect when put in hot water, a comparable
tank of LCO2 will last for as long as 2 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 2.1 metre metal hose for connection
from the Coldflow to a LCO2 tank.
