Notes
The Liquid CO2 Tank is equipped with a pressure relief valve that is fixed to open at 350 p.s.i.g. The pressure
relief valve is in place to ensure the internal Liquid CO2 Tank pressure does not exceed 350 p.s.i.g. As you
approach the ideal operating pressure the relief valve may open slightly and release CO2 gas. Although this is
sometimes noisy this is no cause for alarm, simply close the pressure builder valve by turning clockwise.
DUCTING
If ducting is required the Freezefog output requires a 10" flexible duct, and can be ducted up to 50 feet
horizontally. The ducting is available insulated or non-insulated and can be purchased though an industrial
supply company, or from Le Maitre (Part # CLF).
The Freezefog may also be ducted vertically up to 20 feet, to produce a waterfall or cascade effect. When
ducting fog vertically, the remaining fog in the duct must not be allowed to backflow into the Freezefog. When
this happens repeatedly the glycol in the fog may condensate on the inside of the G300, damaging the
electronic components. See further in this manual for suggested solutions and ducting examples.
Technical Tip
If dividing the output to more than one location while ducting, make sure the sum of all cross sectional areas of
the final duct sizes is equivalent or greater than the cross sectional area of the Freezefog 10" outlet.
Doing this will prevent any backpressure being created by the Freezefog.
The formula for cross sectional area: 0.78539 x (diameter squared)
Example:
The Freezefog outlet has a diameter of 10": 0.78539 x 100= 78.5 "square inches is the area of the Freezefog
outlet.
If you require 3 locations to duct the effect to, then the cross sectional area of the 3 ducts must be greater than
78.5" square inches. For this example, we will try a 6" diameter duct: 0.78539 x 36=28
If we multiply the cross sectional area of the 6" duct by 3" duct outlets: 28 x 3= 84".
84 is greater than 78.5 so the 6" ducting split into 3 ducts is acceptable. Some form of dampering may have to
be used to balance the output of different sized outputs.
