Description

Reliable TNL280 K28(400) Pendent Spray Nozzle with International Threads for Critical Fire Protection

The Reliable TNL280 K28(400) Pendent Spray Nozzle is a specialized, high-performance component engineered for demanding fire protection systems. Designed for use in fixed fire suppression systems, this non-automatic (open) spray nozzle delivers an exceptionally high water flow, making it ideal for high-challenge environments such as tunnel fire protection and other large-scale industrial or commercial applications where rapid and extensive water discharge is paramount. With its international thread compatibility, it ensures seamless integration into diverse global fire safety infrastructures.

  • Ultra-High K-Factor (K28 / 400 Metric): Engineered with a nominal K-factor of 28.0 (400 metric), this nozzle provides an exceptionally high volumetric flow rate, enabling superior water discharge for rapid fire control and suppression in large or high-hazard areas. This advanced K-factor allows for more water flow with less pressure loss, potentially optimizing system design.
  • Non-Automatic (Open) Spray Nozzle Design: The Model TNL280 operates as a non-automatic (open) spray nozzle, meaning it is part of a fixed fire protection system (e.g., deluge systems) and discharges water when the entire system is activated by an external detection system, rather than individual heat activation.
  • Pendent Installation: Designed for installation in the pendent position, this nozzle hangs downward from the ceiling, delivering a broad and effective spray pattern to cover the designated protection area below.
  • International Thread Compatibility: Featuring both 1" NPT and ISO7-1R1 thread options, this nozzle offers broad international compatibility, simplifying installation and maintenance in diverse piping systems worldwide. This addresses critical concerns for projects requiring adherence to various global standards.
  • Corrosion-Resistant Finish: The nozzle is available with either a RASCO500 ceramic coating or Electroless Nickel PTFE (ENT) finish, both cULus Listed as corrosion resistant. This robust coating ensures durability and extended service life, particularly in harsh or challenging environmental conditions.
  • cULus Listed for Reliability: As a cULus Listed component, the Reliable TNL280 TNL280 meets rigorous safety and performance standards, assuring users of its quality and dependability in critical fire protection applications.

Choosing the Reliable TNL280 K28(400) Pendent Spray Nozzle ensures advanced fire suppression for your most critical assets and personnel. Its ultra-high K-factor provides unmatched water delivery for rapid fire control in demanding scenarios like tunnels, large warehouses, or industrial facilities, minimizing potential damage and enhancing safety. The international thread options significantly reduce installation complexity and ensure seamless system integration, making it a highly adaptable solution for global projects. With its proven corrosion resistance and adherence to stringent certifications, this nozzle offers a long-term, trustworthy investment, providing peace of mind and supporting compliance with the highest fire safety standards.
