Fire suppression miraculously works in protecting the buildings by detecting the early signs of fire. Rather than waiting for fire to occur, it works on the signals like smoke, high temperature or flames. The type of suppressing agent plays a critical role in the system. Sprinklers work effectively in suppressing fire, though they cannot be used for electrical fires because water is electrically conductive. Therefore, dry chemical powder emerged as a versatile solution for ceasing the propagation of fire. A dry fire suppression system is a highly useful tool used across residential, commercial and industrial spaces. From its speed to safety, there are numerous benefits of this system.
Versatile and Highly Effective Function
Conventional suppression systems used water to knockdown the flames. Though it is useful, it cannot be relied on because many modern interior spaces have electrical circuits in some form or another. But with dry chemical powder, this problem with resolved.
Here is how a dry fire suppression system operates:
- Heat detectors, smoke detectors, or flame detectors trigger as soon as any of the fire causing element is in the contact with the sensor.
- A high pressure gas is released in the tank where the chemical is stored.
- The pressure forces the pipes into the protected area.
- Powder creates a blanket on the surfaces to stop oxygen supply, breaks the chain reaction and also cools down the surfaces.
Composition
In a dry chemical powder, the composition is everything. Being electrically inert is not the only thing that matters. The powder must be water repellent and should not form a cake on the surfaces because it may extend the post suppression work. Mono ammonium phosphate forms the core of the composition, while additives are added to enhance the essential properties like moisture-resistance, anti-caking, and free-flowing of the chemicals.
Top Benefits of Dry Fire Suppression System
Suppression system with dry chemical powder is quite popular because of its rapid fire knockdown and compatibility with broad fire classes. Here are some of the top benefits of a dry fire suppression system:
High Response Speed: The arrangement of pipes with highly pressurized gas and sensors makes this system have a high response speed to quickly smother fire.
Most Versatile: Being able to be used in Class A, B and C fires, this is one of the most versatile fire suppression systems. It can suppress fire caused by wood, paint, or sensitive electronics.
Weather Resistance: These systems can also be designed for high and low temperatures. Unlike sprinklers, the chemicals do not freeze or expand in this system.
Non-Conductive: Electrically non-conductive is another vital aspect of dry chemical powders. It is mandatory for handling energized electrical equipment.
Conclusion
Dry chemical extinguishing agent is a greatly beneficial formulation because it can handle major fire classes while being cost-effective. As modern spaces are filled with electrical units, the significance of a dry fire suppression system increases. We at Foamtech Antifire Company have developed many variants of these systems. From the standard ABC fire suppression to specialized system for metal fires and high temperature zones, our range is huge and innovative.
