Adjustable inert gas generation assembly for water-based fire protection systems

摘要

An adjustable inert gas generation assembly for producing a flow of inert gas for introduction into a pipe network of a fire protection system includes an inert gas generator with an outlet in fluid communication with the pipe network and configured for selectively- producing a flow of inert gas to the pipe network at least at a first purity level and a second purity level, wherein the first purity level is produced while the assembly is in a first mode and the second purity level is produced while the assembly is in a second mode; wherein the second purity level is higher than the first purity level; and a control circuit in electrical communication with the inert gas generator and configured to selectively switch the inert gas generator between the first and second modes.
