Vertical (pendent) fire sprinkler head designed for reliable fire extinguishing system protection. Engineered to activate at 68°C (155°F) and connect to DN20 piping, this sprinkler head provides targeted, downward water discharge for effective local suppression in automatic fire protection systems. Key benefits Reliable temperature activation: Opens at 68°C to respond when heat from a developing fire reaches the set activation point. DN20 compatibility: Sized for standard DN20 supply piping and fittings, simplifying replacement or installations on systems using DN20 branches. Pendent (vertical) discharge: Delivers water downward from the ceiling for direct coverage of the protected area. Simple integration: Designed for use in automatic wet/dry fire sprinkler systems to reduce fire spread and protect property and occupants. Main attributes Temperature rating: 68 degrees Celsius (activation temperature). Connection size: DN20 (nominal 20 mm piping compatibility). Orientation: Pendent / vertical installation (water discharges downward). Function: Automatic fireextinguishing sprinkler head for use in fire protection systems. Installation: For installation on DN20 threaded or compatible fittings per system design and local codes. Manufacturer specifications: Follow the manufacturer's installation instructions, material specifications, and system requirements for correct selection and performance. How it solves problems Early activation at a defined temperature helps contain fires before they grow, limiting damage and risk to occupants. Direct downward spray pattern targets the area beneath the sprinkler, providing efficient coverage where it's needed most. DN20 sizing and standard orientation reduce installation time and compatibility issues with existing piping. Typical applications / use cases Commercial and office ceilings: Protect openplan offices, corridors, and meeting rooms where pendent sprinklers provide consistent ceiling coverage. Storage areas and warehouses: Use in aisles or low to mediumheight storage racks where downward water distribution is required. Residential and multifamily buildings: Suitable for ceilingmounted protection in apartments, corridors, and utility rooms when DN20 piping is specified. Installation and selection notes Use only as part of a properly designed and engineered fire sprinkler system. Confirm system water supply, hydraulic calculations, and spacing with a qualified fire protection engineer. Confirm compatibility with local building codes, standards, and any required approvals or listings before installation. Follow the manufacturer's instructions for mounting, orientation, and maintenance to ensure reliable operation. For reliable activation at 68°C and straightforward integration with DN20 piping, this pendent/vertical sprinkler head is a practical choice for many automatic fire protection systems.
