Forede 140L Capacity Mobile Foam Unitss304 1.5inch

The adjustable foam - solution ratio allows for customization based on the type of fire. A lower ratio (e.g., 1%) is suitable for lighter hydrocarbon fires, conserving foam concentrate. A higher ratio (e.g., 6%) is better for more challenging fires involving heavier hydrocarbons or polar solvents, providing a more concentrated foam solution for effective extinguishing.

Yes, it can be used in confined spaces. However, proper ventilation should be ensured to avoid the accumulation of foam and any potential vapors. Also, operators need to be cautious about maneuvering the unit within the limited space and ensure that the foam discharge does not create hazardous conditions.

Regularly inspect the fire hose for any signs of wear, such as cracks, abrasions, or leaks. After use, it should be cleaned and dried thoroughly to prevent the growth of mold or mildew. Periodically, the hose should be pressure - tested to ensure its integrity and performance.

The refill time depends on the capacity of the unit and the flow rate of the refill source. For the 120 - liter and 140 - liter units, with a suitable refill setup, it may take approximately 5 - 10 minutes, but this can vary based on the actual conditions.

It can be used in cold weather, but precautions are needed. The foam concentrate may become more viscous in low temperatures, affecting the flow and performance. It's advisable to store the unit in a heated area before use or use a foam concentrate suitable for cold temperatures. Also, check for any signs of freezing in hoses or components before operation.
