Dry Sprinklers
Dry sprinklers are designed for use in areas where the sprinkler may be subjected to freezing conditions. Dry sprinklers may be used in dry systems, where the entire area being protected is subject to freezing, and wet systems, where a small portion of the area being protected is subject to freezing.
Until activated, dry pipe sprinkler systems are typically filled with nitrogen gas or pressurized air instead of water. Dry pipe systems are ideal for fire protection in areas such as parking garages, loading docks, balconies and canopies, unheated storage facilities, and water sensitive areas where pipes are likely to freeze under cold conditions.
