For commercial and residential buildings all around theregion, having a working fire sprinkler system installed is the single most effective means of fighting medium to large scale fires. Expert Fire Engineers provides a full line of fire sprinkler system services from design and installation to inspections, testing, and maintenance.
Utilizing our experience of more than two decade in this domain, we are engaged in offering a wide array of Fire Sprinklers System. These systems are designed using premium quality materials with the influence of modern art of technology. Our Fire Sprinklers System is installed in numerous automobile factories, chemical power plants, science laboratories and commercial buildings for safety against fire. Furthermore, we provide these systems at reasonable prices to our clients.
A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by fire sprinklers, over 99% of fires were controlled by fire sprinklers alone.
Sprinkler Head Types
There are a number of different types of sprinkler heads that meet different needs
Fusible Link Sprinklers vs. Glass Bulb Sprinklers
All wet-pipe sprinklers are held closed by either a fusible link or a glass bulb that contains a heat-sensitive liquid.
A fusible link sprinkler head has a two-part metal element that is fused by a heat-sensitive alloy. The link holds the pip cap, or plug, in place. Once the ambient temperature around the sprinkler head reaches a specified temperature, the alloy releases and the metal elements separate, which causes the pip cap to fall away. Water is then released. Note that water is only released by sprinkler heads where the ambient temperature reaches a specified level - therefore, water is only released in the area of a fire, which helps limit water damage.
Glass bulb sprinkler heads have a small glass reservoir that holds a heat-sensitive liquid. This glass bulb holds the pip cap in place. When the ambient temperature of the liquid reaches a certain level, the liquid expands causing the glass bulb to break, which allows the pip cap to fall away releasing water. As with the fusible link heads, water is only released where the ambient temperature reaches a certain level, which helps limit water damage.
Most sprinkler heads contain a small bulb with a colored liquid inside. This bulb acts as a plug to prevent water from escaping out of the sprinkler. The heat from a fire causes this liquid to quickly expand. Once the pressure in the vial gets too high, the bulb bursts and releases the water behind it.
The liquid inside the bulbs comes in a variety of colors, and each color represents the temperature required to activate the sprinkler:
- Orange – 57°C
- Red – 68°C
- Yellow – 79°C
- Green – 93°C
- Blue – 141°C
- Purple – 182°C
- Black – 227°C
Since the fire sprinklers are activated by heat, there is no risk of accidental activation of your fire sprinkler system by smoke or dust in the air. That said, the bulbs are very fragile and any tampering could cause them to go off. If a sprinkler head gets accidentally knocked off (by a forklift, truck, repairman, etc.), there’s going to be lots and lots of water flowing through that sprinkler head until the system is shut down.
