How can engineers and contractors design wet fire sprinkler systems equipped to prevent corrosion and dry systems equipped to prevent freezing? That has long been a question central to code requirements and new product development.

Recent innovations have presented a few possible answers to that question. By including new products such as air vents, self-draining auxiliary drains in heated cabinets and flood elimination devices, engineers and contractors can design systems better equipped to protect themselves against the common pitfalls of corrosion and freezing.
