Dry Sprinklers Brief Introduction
forede® Dry sprinklers, also known as Dry Pipe Fire Sprinklers, are an innovative and effective way of protecting buildings from fire. A dry sprinkler is composed of a special pipe and a sprinkler mounted at the outlet of a special pipe. A seal is provided at the entrance of the pipe to prevent water from entering the pipe before the sprinkler is operated.They work by using pressurized air or nitrogen to fill the sprinkler pipes instead of water. When a fire breaks out, a valve opens and the air or nitrogen escapes, allowing water to flow into the pipes and extinguish the fire.
One of the primary benefits of dry sprinklers is that they are ideal for buildings in which freezing temperatures are a concern. Traditional wet sprinklers use water, which can freeze in the pipes if the temperature drops below freezing, rendering the system useless. With dry sprinklers, this is never an issue.
Moreover, dry sprinklers also offer flexibility and versatility in terms of application. They can be used in a variety of settings, including cold storage facilities, unheated warehouses, parking garages, and outdoor areas. This makes them an excellent choice for a wide range of businesses and industries.

Dry Sprinklers for fire sprinkler system applications
Dry sprinklers is a widely used fire sprinkler system, which is suitable for some specific places and environments.

Dry Sprinklers in cold Warehouse
Dry Sprinklers are a vital part of fire sprinkler systems in cold warehouses. Unlike traditional sprinkler systems that use water, dry sprinklers use compressed air or nitrogen to hold back the water in pipes until triggered. This feature makes it ideal for areas that are prone to freezing temperatures, preventing water from freezing in the pipes and causing damage to the system.
Dry sprinklers offer several benefits, including their ability to protect valuable goods and equipment in cold warehouses. They can quickly respond to a fire, releasing water evenly across the entire area, which can effectively control or extinguish a fire.
Moreover, dry sprinklers are cost-effective and require less maintenance compared to other sprinkler systems. They can operate with lower-pressure water sources, resulting in lower installation and operating costs. Additionally, dry sprinklers require less maintenance since they have no water sitting in pipes, lessening the risk of corrosion and leaks.
Dry Sprinklers in machine room
Dry sprinkler systems are an important component of fire sprinkler system in machine room. These systems work by using compressed air to power water through the sprinkler heads, which then extinguishes the fire. Unlike traditional wet sprinkler systems, dry systems use pressurized air instead of water to prevent freezing in colder climates.
One of the advantages of dry sprinkler systems is that they require less maintenance than traditional wet sprinkler system. Because the pipes are not filled with water, there is less risk of corrosion or damage. Additionally, dry systems are less likely to accidentally discharge water, which can cause costly damage to equipment or property.
Installing a dry sprinkler system in a machine room is an excellent way to ensure that fires will be quickly and effectively extinguished. This not only protects the equipment and property within the room, but also reduces the risk of injury or death to those who may be present during a fire.
In short, dry sprinkler systems are an essential component of fire sprinkler system in machine rooms. By installing a dry system, you can rest assured that your equipment, property, and personnel will be kept safe in the event of a fire.


Dry Sprinklers in underground parking
Dry sprinklers are a type of fire protection system that is commonly found in underground parking lots. They are designed to quickly detect and suppress fires, helping to prevent major damage and keep people safe.
Unlike traditional sprinkler systems, dry sprinklers are filled with pressurized air or gas instead of water. This makes them ideal for use in areas where water damage could be a major issue, such as underground parking garages. In the event of a fire, the system automatically releases the gas or air, which then opens the sprinkler heads and allows water to flow out and extinguish the flames.
Dry sprinklers offer a number of benefits for underground parking garages. First and foremost, they provide a high level of protection against fires, which can be particularly devastating in enclosed spaces like parking lots. They also help to minimize water damage, as the water is only released when needed and in controlled amounts.
Dry Sprinklers in Office building
In modern buildings, dry sprinkler system has become one of the necessary facilities. Especially in high-rise buildings such as office buildings, its role is indispensable. A dry sprinkler system is a special fire extinguishing system whose operation is based on an efficient design that guarantees security for all types of offices to protect the safety of employees and office workers.
Dry sprinkler systems reduce potential water damage and equipment damage. Especially in the design of fire suppression systems, it is very important to prioritize the prevention of property damage and casualties.
Dry sprinkler systems also have the advantage of operating at extreme temperatures. Since there is no water in the system, there is no problem of icing. This is a matter that must be considered when the fire extinguishing system is designed in the cold winter in the north. This means that even in these harsh conditions, the dry spraying system can continue to operate and provide the necessary safety and security.
