While there are many types of sprinkler systems available, the two most commonly used are wet and dry systems. Fire Systems, Inc. repairs, installs, and inspects all types of sprinkler systems for commercial businesses in Atlanta and throughout the state of Georgia. Fire Systems can also help you choose which system is best for your fire protection needs.

Wet vs. Dry Systems 

Both wet and dry sprinkler systems extinguish fires using water, just in different ways.

In a wet pipe sprinkler system, the pipes are filled with pressurized water. When a fire occurs, the system immediately discharges water to extinguish the fire.

Conversely, dry pipe sprinkler systems are filled with pressurized nitrogen or air that keeps water at a riser.  When a dry system goes off, the pressure in the pipes drops, a valve opens, and water flows through the pipes and out to extinguish the fire.

Wet Sprinkler Systems

The sprinkler heads in a wet system are connected to pipes that are filled with water and automatically go off when a fire is detected. Wet sprinkler systems are the number one choice for most businesses because they’re simple to use and require little maintenance. They are also very reliable since the water is automatically dispersed when a fire occurs.

Some important things to note about  wet sprinkler systems are that they cannot be used in places where temperatures reach below 40˚ F (4.44 ˚C), and they are not ideal for protecting spaces that house sensitive equipment such as computers or important documents.

Dry Sprinkler Systems

Sprinkler heads in a dry system are connected to pipes that are filled with pressurized nitrogen or air that hold water back until a fire is detected. They are the second most commonly used system, and are ideal for unheated buildings, parking garages, and warehouses since these types of properties can experience temperatures below 40˚F (4.44 ˚C). Dry sprinkler systems are also recommended for protecting areas that store sensitive equipment like computers or important documents to minimize damage.

It’s important to note that choosing a dry sprinkler system can have its downsides. For example, there can be higher installation and maintenance cost due to the increased complexity of dry sprinkler systems.

Deciding which sprinkler system is best for you will ultimately depend on your needs as a business. Let Fire Systems, Inc. help you make the right decision as this is a critical part of a building’s fire protection system. Call 770-333-7979 or visit our website to schedule a consultation today.
