The sprinklers are designed for dry systems and preaction systems where it is necessary to prevent water or condensation from entering the drop nipple before sprinkler operation. They may also be installed in spaces subject to freezing and supplied from a wet system in an adjacent heated area.  The special Polyester and Electroless Nickel PTFE (ENT) coatings are listed/approved for installation in corrosive environments. Refer to technical data sheet for design and installation requirements.
