ZSTX 15-79℃ Upright Acid-washed Fire sprinkler heads
Upright fire sprinklers spray water upward to a concave deflector, producing a dome-shaped spray pattern. They install deflector-up to cover specific areas and to prevent ice and debris from collecting in the head. Upright sprinklers are installed where obstructions interfere with coverage and in dry-pipe systems facing freezing temperatures.
