Low Pressure Carbon Dioxide Fire Suppression System

The ANSUL® Bulk Low Pressure, Carbon Dioxide System is ideal for non-occupied fire hazards requiring large amounts of agent with limited storage space. A single bulk tank can store from 3.75 to 46 tons (3,402 to 41,730 kg) of carbon dioxide, which is maintained in a stand-by, fire-ready state that allows the system to provide effective

Carbon Dioxide (CO2) in Fire Suppression Systems

Application Example: A coal pulverizer - when it is started and coal is added, there is a point when the suspended coal particles and the air are in the explosive range. The same condition exists on shut down as coal is removed. CO2 can make this start up and shut down safe by inerting the air/coal mixture and preventing an explosive atmosphere.
