According to the National Fire Protection Association (NFPA), fire sprinkler systems can reduce fire deaths by around 87%. Do you have a fire sprinkler installed in your business? Having one properly installed and maintained can mean your life. In this article we will see the main differences between two common fire sprinkler systems: Wet and Dry.
Wet Sprinkler Systems
A wet sprinkler system is the most common system. These always have water in the pipes. When there is a fire, the temperature near the sprinkler head rises. When the temperature reaches a certain height, the frangible bulb or fusible link breaks breaks allowing the pressurized water to burst out, hence putting out the flames.
Advantages:
Wet sprinkler systems are the most reliable and cost effective. Because they are always filled with water, their response is quick and effective. These systems are usually easier to install and maintain, thus cutting down on their cost.
Disadvantages:
Wet sprinkler systems cannot be used in buildings where the temperature falls below zero. An alternate system is recommended if there is any chance of the pipe freezing. Another possible disadvantage would be leaks developing in the pipelines. Corrosion can cause leaks that damage your buildings.
Dry Sprinkler Systems
Dry pipe sprinkler systems are filled with pressurized air or nitrogen instead of water. When a fire is detected, the air pressure in the pipes is reduced and a valve opens to allow water to flow into the sprinkler pipes and extinguish the fire.
Advantages:
Dry sprinkler systems are better adapted to cold climates and will not freeze. A dry sprinkler system can be installed in addition to a wet sprinkler system. These systems are often used in loading areas, commercial freezers and unheated warehouses.
Disadvantages:
Because they require a constant, reliable air supply and special components, dry sprinkler systems are more complex. Therefore, they are often harder to maintain. Because of the intricacy of the design, these systems are also more expensive to install. During an emergency, these systems also have a slightly longer response time, up to 60 seconds longer. Pipes in a dry sprinkler system also have a high probability of corrosion. The pipes must be completely drained and dried after every use.
Fire Sprinkler Systems: Which is right for you?
As we have seen, both fire sprinkler systems have advantages and disadvantages. Each space requires its own specific sprinkler system. Hiring a professional can help you choose the right system.
