Abstract (en)

[origin: WO9110477A1] An apparatus and system for storing and supplying liquid CO2 at low pressure for extinguishing fires. The apparatus comprises a pressure vessel (13) for storing liquid CO2 at low pressure, a cooling means (29) in contact with gaseous CO2 in the vessel to maintain the low pressure, an inlet (24) and outlet (32) to fill the vessel and a supply conduit (17) communicating with a lower portion of the interior of the vessel to allow liquid CO2 to pass from the vessel and into a reticulation system. A number of pressure vessels can be coupled together through a manifold (165) to provide the required amount of liquid CO2 to a risk site. Supply valves (18) or manifold valves (173, 174) can be operated by a sensor (175, 176) in a risk site and a logic processor (177) can be used to regulate the valves and thereby the liquid CO2. The apparatus and system is particularly designed as a replacement for current halon systems which cause damage to the ozone layer.
