Wet Fire Sprinkler Systems
There are many fire sprinkler systems that are best in different environments and circumstances.
Since different circumstances give rise to different kinds of fires, sprinkler systems must be able to respond accordingly. Depending on the building and the activities performed inside, one type of fire sprinkler system is likely to perform better when compared to another. For this reason, Fajar Baru. offers four different types of fire sprinkler systems. Each one has benefits that better serve different environments and customer needs.
Dry Fire Sprinkler Systems
Cold Environments with Temperatures Below 40°F
Dry-pipe systems are the sprinkler system of choice when the piping will be exposed to temperatures below 40 degrees F. Dry sprinkler system piping does not contain any water and is charged with pressurized air, or sometimes nitrogen. When a fire occurs and generates enough heat to release the sprinklers, the air in the pipes escapes, resulting in a drop in system air pressure, which allows the dry valve to open and water to flow to the open sprinklers.
Why Dry?
Although wet sprinkler systems are extremely effective against a spreading fire, they can present challenges in cold climates. When the weather is cold, the water stored inside the pipes of a wet pipe sprinkler system is susceptible to freezing, which can block the flow of water in an emergency. Furthermore, cold weather can damage the pipes that make up a wet pipe sprinkler system. As water freezes and turns to ice, it expands, causing so much pressure that the pipes can become warped or even burst.
It’s in these situations that a dry pipe sprinkler has the edge. Instead of water, the pipes in these systems are filled with pressurized air, such as nitrogen. When the sprinkler system is triggered, the air is released, lowering air pressure inside the piping. That decrease in air pressure allows water to flow into the pipe system and through the sprinkler heads. While this results in a slight delay from when the fire starts and when the water is released, with dry pipe sprinkler systems, you can be sure that you will always have a properly functioning and undamaged fire sprinkler system in cold temperatures.
Foam Fire Sprinkler Systems
Manage the Challenge of Flammable Liquid Storage with Foam Sprinkler System Technology Solutions from Fajar Baru.
Flammable liquids, stored in warehouses, airport hangars, marinas, and manufacturing or processing facilities, create high risk, volatile environments. Foam is the agent of choice whenever there is a possibility of a flammable liquid fire. Foam, mixed with water, blankets the liquid that is on fire, eliminating the oxygen supply, cooling the fire, and finally extinguishing it. Protect your assets and the people who work in these high risk environments.
We Determine the Right Foam Sprinkler System for Your Facility
Every type of foam has its application. Fajar Baru experts will recommend the type of foam—low, medium or high expansion—for the foam sprinkler system that your particular facility and application requires. For example, high-expansion foams are used when an enclosed space, such as a hangar, must be quickly filled. Low-expansion foams are used on burning spills. Whatever the need, we can guide you to the appropriate choice.
Some warehouses and facilities store flammable liquids. Fires that break out in these kinds of locations can be extremely difficult to extinguish using water alone. Luckily, foam sprinkler systems are quite effective at putting out fires on spilled flammable liquids. These fire sprinkler systems contain a specialized foam mixture that is released when a fire is present. As the foam covers the flames, it blocks its access to the oxygen needed to continue burning. In other words, the foam completely smothers the burning liquid, preventing further damage to property and people.
Foam sprinkler systems can be equipped with different kinds of foam: Aqueous Film-Forming Foam (AFFF) and Film-Forming FluoroProtein foam (FFFP).
