Suppression Systems

Crest Fire is Vancouver Island's leader in fire suppression technology, system installation, and inspection. We are well-versed in all types of fire suppression systems on the market today.

Types of Fire Suppression Systems

1. Water-Based Fire Suppression Systems

One of the most common fire protection systems uses water to extinguish fires and protect property. Water is housed in a reservoir and or connected to the water supply. The system detects the fire and sprays a water mist, or heavier water level, to extinguish the fire. The most significant advantages are it's inexpensive in comparison to other types and easy to replace. The downfall to water-based suppression systems is that they can cause severe water damage and should not be used around electronics.

2. Chemical Foam Suppression Systems

One of the most common places for fires to start is in the kitchen because of a cooking mishap or hot grease. Chemical foam systems are designed specifically for these types of conditions. They are placed under cooking canopies, cause minor damage, and are easy to use. Kitchen systems do need to be off when an inspection is being conducted by our qualified technicians. Example: Wet Chemical Systems, NFPA 17A; these systems are often used for kitchen suppression.

3. Pneumatic Heat Detection Tube

Fire extinguishers are standard fire suppression devices, but they are manual use. The pneumatic heat detection tube is an extinguisher with a fire detection system. Once the temperature reaches a certain level, it blows a small hole in the pipe, and the extinguisher foam ejects to put out the fire.

4. Pressurized Gas System

With a pressurized gas system, the gas is kept as a liquid under pressure using liquid nitrogen. When a fire is detected, the system releases the gas, and it has a chemical reaction with the fire to extinguish it. This is ideal for server rooms and other areas with high-end electronics. It's compact since the gas is under pressure, and it doesn't cause an oxygen reduction.

5. Foam Deluge Systems

A foam deluge system is used in areas where water suppression isn't possible such as transformers and oil tanks. When a fire is detected, water mixes with the foam to expand it and extinguish the fire. These types of extinguishers are effective for outside areas, but they do create a giant mess once deployed.
