Sprinkler System Types

Dry Pipe

Dry pipe sprinkler systems are charged with pressurised air, and the water within this system is retained by a control valve.

In the event of a fire detection by the sprinkler's sensors, a decrease in air pressure prompts the valve to open, allowing water to enter the sprinkler and contribute to fire protection. These systems are applicable in sub-zero temperatures, making them well-suited for structures lacking heating, such as commercial freezers, garages, and warehouses.

Wet Pipe

The wet pipe system stands as the most prevalent type of sprinkler system. It functions by consistently holding water in the pipes above the sprinkler heads. Connected to a water supply, the system ensures a continuous water stream and discharges it upon detecting heat from a fire.

Primarily utilised in buildings where freezing is not a concern, the wet pipe sprinkler system safeguards the water supply integrity.

Known for its ease of installation and relatively low maintenance costs, this system provides a high level of reliability, crucial for applications where extended periods of inactivity may be required.

Pre-Action

In a pre-action sprinkler system, the pipes are initially filled with air, and water is introduced into the pipes only when triggered by a detector, such as a smoke detector.

This system is frequently employed to safeguard valuable items in buildings like museums or libraries, where inadvertent activation could potentially result in irreversible damage to precious collections. Similar to the dry pipe system, the pre-action sprinkler keeps water out of the pipes through a pressurised air valve.

However, for the pre-action sprinkler to engage, it requires the initial detection of a fire (via heat sensors or smoke detectors). This detection opens the pre-action valve, allowing water into the pipes, and from there, the system operates akin to a wet pipe sprinkler system.

Deluge

In a deluge fire protection system, the pipes contain unpressurised air, and the sprinkler heads remain in an open state. Water is introduced into the pipes exclusively when the system is triggered—either by a fire alarm, smoke detector, or through a manual pull station that prompts the deluge valve to open, allowing water to freely flow to all sprinklers.

In contrast to the dry pipe system, which activates sprinklers solely above the specific hazard, the deluge system initiates the opening of all sprinkler nozzles.

The deluge sprinkler system is the preferred choice for locations characterized by a rapid fire hazard or a substantial volume of highly flammable contents.

Water Mist

The low-pressure water mist extinguishing system is rooted in sprinkler technology, offering significant advantages for building owners and operators due to its notably low water consumption.

The EconAqua system, in comparison to traditional sprinkler systems, achieves a remarkable reduction of up to 85% in water usage. Its functionality and structure closely resemble those of a conventional sprinkler system, ensuring simplicity in comprehension.

Furthermore, the design and installation process mirrors that of a traditional sprinkler system, allowing end-users to leverage the expertise and experience of the licensed installer.
