Water mist spray nozzle for medium speed water curtain and impact spray applications. Designed as a metal nozzle assembly with a frame, piece, and splash plate with dust proof net for stable mist formation and clog resistance. Key benefits Produces a medium speed water mist and water curtain that improves area coverage and vapor suppression in hazardprone zones. Impact nozzle design generates fine droplets and directional spray for effective cooling and dilution without large volume discharge. Metal construction offers durability for installed fire protection and process spray systems. Simple modular parts ease inspection and maintenance. Main features and specifications Function: Medium speed water mist nozzle, also called impact nozzle, suitable for water curtain and misting spray duties. Construction: Metal components including frame, , and splash plate with dust proof net. Connection sizes: DN15 1/2 inch and DN20 3/4 inch compatible with common piping and fittings. Service conditions: Intended to protect areas containing flammable liquids, gases, and solids with a flash point above 68. Classification: Water curtain type fire sprayer and water misting nozzle for industrial spray and protection systems. Compatibility and installation notes Fits standard DN15 and DN20 pipework and 1/2 inch and 3/4 inch threaded connections. Install in arrays or banks to form a continuous water curtain or targeted mist protection zone. Periodic inspection of the splash plate dust proof net is recommended to maintain spray quality and prevent clogging. Typical use scenarios Storage tanks and bunded areas where a water curtain can limit vapor spread and reduce heat exposure to adjacent equipment. Loading and unloading bays for flammable liquids to provide localized misting and vapor control during transfer operations. Industrial process areas handling combustible solids or gases where a medium speed mist can help dilute vapors and protect critical components. This nozzle is intended for integration into water spray and curtain systems. Select the appropriate connection size DN15 1/2 inch or DN20 3/4 inch to match existing piping and ensure correct placement for effective coverage.
