Our Carbon dioxide trolley-mounted type fire extinguishers are portable fire suppression devices that use CO2 to extinguish fires. They are designed to be mounted on a trolley for easy transport & maneuverability. These are effective for combating Class B and Class C fires, which involve flammable liquids and electrical equipment, respectively. They work by displacing oxygen & cooling the fire, effectively suffocating it. Our Carbon Dioxide Trolley Mounted Type Fire Extinguisher provides a convenient and effective means of combating fires and protecting property and occupants.
