What is dry pipe sprinkler system?
Just so, what is the difference between a wet and dry sprinkler system?
In a wet system, the pipes are filled with pressurized water. Conversely, dry systems are filled with pressurized nitrogen or air that keeps water at a riser. When a dry sprinkler system goes off, the pressure in the pipes drops, a valve opens, and water flows through the pipes and out to extinguish the fire.
Also, where are dry pipe sprinkler systems used? Dry pipe sprinklers are used in applications where you can't protect pipes from freezing temperatures.
These areas include:
- Exposed garages.
- Drive-through loading areas or docks.
- Water-sensitive storage.
- Unheated warehouses.
- Garden or supply centers.
- Cooler or freezer storage.
- Unconditioned attics.
Similarly, what is the main reason for using a dry pipe sprinkler system instead of a wet pipe sprinkler system?
When a sprinkler head activates, the compressed air is released and the pressure relief opens the valve, allowing water into the system. However, dry pipe systems have a slower response than wet pipe systems because water must travel from the source to the activated sprinkler head.
What is a wet pipe sprinkler system?
A wet pipe sprinkler system is a sprinkler system employing automatic sprinkler heads attached to a piping system containing water and connected to a water supply so that water discharges immediately from sprinklers opened by heat from a fire.
