Wet Pipe Sprinkler Systems are the most common and widely used fire suppression method currently available. Therefore, the system requires relatively low installation and maintenance expenses. They operate with no other major systems or equipment other than pipes and sprinkler heads which also allows for ease in making modifications. This system’s pipes contain pressurized water and when the system is activated by heat, the closed sprinkler heads immediately release water. These systems are typically installed in buildings where freezing temperatures are not a concern.
Dry Pipe Sprinkler Systems contain pipes which are filled with pressurized air or nitrogen, rather than water. The air then holds the dry pipe valve in a closed position until fire causes one or more sprinklers to operate. Air then escapes, the dry pipe valve releases, and water flows through the open sprinklers. Dry pipe sprinkler systems provide involuntary protection in environments where freezing is possible.
Pre-Action Sprinkler Systems are similar to a dry pipe system as water is not normally held within the pipes. Instead, the water is held from piping by different means that control a pre-action valve. This is controlled by flame, heat, or smoke detection. The system must first recognize a developing fire and open the valve. Pre-Action Systems are installed in water sensitive environments as they contain an added level of complexity reducing the chances of unintentional water being released.
Standpipe Sprinkler Systems operate using piping that connects a water supply to hoses. They are designed to provide the building or fire department access to the water source. Within buildings, Standpipe Systems then serve a similar purpose to fire hydrants and are strategically positioned and accessible. These systems are commonly found in large floor area buildings to decrease the amount of hoses necessary.
Foam Fire Sprinkler Systems are used when there is a possibility of a special hazard. We provide a complete line of foam assisted systems, which include closed & open head systems as well as high expansion systems. The foam mixes with water, expands over the liquid, cools the fire, and in turn extinguishes it. The foam is stored in a tank and can be added via the sprinkler water through a bladder tank—foam is forced from the tank by involving water around a bladder which moves the foam from the tank—or foam pump. The pump uses the foam at a required concentration in order to suppress the fire.
Deluge Sprinkler Systems utilizes Open Sprinkler Heads which attach to a deluge pipe that is connected to a water supply. This detection system, which is installed in the same area as the sprinklers, then recognizes smoke or heat, activates a valve, and releases water to all sprinklers. These systems are best for environments that are considered high hazard areas.
