Sprinkler Types
Viking offers a wide range of sprinklers and spray nozzles to suit different fire risks and protection needs for all types of buildings and applications.
1.Standard Sprinklers: This is the most common type of sprinkler. It opens when a glass bulb bursts (or fuses) at a specific temperature, such as 57, 68, 79, 93, or 141°C, allowing water to spray onto the fire area.
