Sprinkler system that is used in high hazard environment. All sprinkler heads are open and when fire is detected, water flows through all the sprinkler heads to floor the affected area. In this system, the pipes are empty when not active. Water is being held back by a valve until the system is activated. It is design to smother fires quickly.

• Water mist system

• Flood System

• Deluge System

• Dry pipe System

Sprinkler system that uses fine droplets to extinguish a fire. It is effective as the tiny droplets will cool the flame, displace the oxygen which feeds the fire, and the droplets absorb the heat as it evaporates due to the heat. This system uses less water when compared with others.

• Water mist system

• Flood System

• Deluge System

• Dry pipe System

In this sprinkler system, the pipes are filled with nitrogen or pressurized air instead of water. When a sprinkler detects a sudden increase in temperature, it activates and the air pressure in the system drops. This causes the valve to open and water floods into the pipe and sprinkler system.

• Pre-action System

• Flood System

• Deluge System

• Dry pipe System

In this sprinkler system, the pipes are filled with nitrogen or pressurized air instead of water. It utilizes heat or smoke detectors to send signals to a valve. Once the heat or smoke detector is activated, the valve opens to let water into the system. However, water is yet to be discharged. The sprinkler head must first detect an increased temperature indicating that there is a fire before water pours out. This added safety feature makes this system for applications such as museum, server rooms, libraries, data farms and other water sensitive areas
