A dry pipe fire suppression system is utilized when area temperatures cannot be maintained above 40 degrees Fahrenheit. More complex in design, dry pipe systems utilize compressed air or nitrogen to hold water back as far as the dry pipe valve, which must be located in a heated area. Dry systems are most commonly installed in attics, unheated building entries and exits, covered loading docks, and unheated warehouses. These systems tend to be more expensive to install and maintain than wet systems, yet they remain an effective fire suppression alternative when the protected area simply cannot be heated.
Underground piping must be flushed of debris before connection to any fire suppression system. Read more about the flushing process here.
Dry fire suppression systems:
- can be used when the space or building will not be heated.
- have pipes pressurized with nitrogen or air to hold water back to a valve in a heated area.
- are most commonly installed in attics, unheated building entries and exits, covered loading docks, and unheated warehouses.
