Which type of sprinkler is designed to project upward with deflectors that spray water downward?

The upright sprinkler is designed to project upward, featuring deflectors that then direct water downward. This design is particularly effective for certain applications where the ceiling height or layout of the environment demands a sprinkler that can efficiently distribute water over a wider area from above.

The upward projection allows the water to cover a broader space after being deflected, making it suitable for areas where there is sufficient space between the sprinkler and any obstructions, such as storage racks or tall equipment. This type of sprinkler is commonly found in warehouses and other environments with high ceilings where it is essential to ensure that fires can be effectively suppressed.

Other types of sprinklers, such as pendant, sidewall, and concealed sprinklers, have different designs and functions, which do not include projecting upward with downward spraying deflectors. For example, pendant sprinklers hang from the ceiling and spray water downward directly, while sidewall sprinklers are designed to be mounted on walls and also distribute water in a different manner. Concealed sprinklers are hidden from view until activated and feature designs suited for aesthetic considerations, again distinguishing them from the upward-projecting action of upright sprinklers.
