Those who are looking for a fire sprinkler that has aesthetic appeal, then opt for concealed sprinkler. Its installation is done to minimize its visibility. Hidden or concealed sprinklers are not easily visible, unlike traditional fire sprinklers, which are surface-mounted and visible. Often, they are used in hotels and restaurants where aesthetics are important. As they are hidden, they are blended into the surrounding design. They may be concealed, but that does not mean they cannot work. They will work just like traditional surface-mounted sprinklers.
