Tyco D4A ProtectoSpray Directional Spray Nozzle

The Tyco D4A ProtectoSpray is an open directional spray nozzle designed for use in fixed water spray fire protection systems. It is intended for applications requiring effective cooling, exposure protection, and fire suppression through the controlled discharge of medium-sized water droplets.

The D4A utilizes an external deflector design to produce a uniformly filled cone-shaped spray pattern, providing comprehensive coverage of exposed surfaces. Its distinctive four-arm body construction offers additional protection against mechanical and physical damage, making it particularly suitable for demanding industrial environments.
