ECS In-Line Corrosion Detector

  • 2017 Corrosion Innovation of the Year
  • UL Listed for use in fire sprinkler systems
  • Monitors internal corrosion activity in all water based fire sprinkler systems
  • Rated up to 175 PSIG
  • U.S. Patent No. 9,095,736

The ECS In-Line Corrosion Detector (model ILD) is designed to provide an early warning indication that the corrosion rate within fire sprinkler system piping is at an unacceptable level. The detector is the first true in-situ corrosion monitoring device designed for the fire sprinkler industry that effectively addresses NFPA 13 corrosion monitoring requirements.

  • Designed for corrosion detection in both wet pipe and dry pipe sprinkler systems
  • Installed within sprinkler system piping where corrosion is expected to be the worst
  • Matched with exact same size, schedule and material as sprinkler system piping
  • Provides automatic notification of corrosion activity via local or panel notification
  • Does not require scheduled replacement of test coupons

  • Push-button feature on remote test indicator for local notification
  • Provides 360° surface area for comprehensive corrosion detection
  • Externally milled section of device provides early warning detection without interfering with system hydraulics
  • Included pressure switch is UL listed/FM approved for use in fire sprinkler systems
  • Device is roll grooved for easy installation and removal
  • Available in multiple configurations with sizes 1″ thru 8″, black steel or galvanized steel, and schedule 10 or schedule 40

Pre-order Instructions

  • Consult with ECS engineering team regarding best location for installation
  • Device must be installed where corrosion is most likely to occur: pockets of trapped air in wet systems, pockets of trapped water in dry systems
  • When pipe replacement is needed on existing systems install device with new piping at location of previous corrosion damage
  • Once installation location has been determined verify pipe size, material, and schedule and provide to ECS at time of order

Installation Instructions

  • Device requires removal of 18″ pipe section in retrofit applications
  • Requires grooved couplings (not included) for attachment to system piping
  • Wire to monitoring system from dry contact in pressure switch (if applicable)
