Gas Relief Line Vent
Gas Detector LBW-WATCHMAN-RLV

In addition to gas detection in compressor rooms and refrigerated spaces, it is recommended that you install gas sensors on your vent lines to monitor for gas releases into the atmosphere. In the event of a release, the detector can alert safety personnel, so swift action can be taken to reduce the potential exposure to the surrounding community and the onsite workers.  

Cool Air Inc. offers a full line of relief line vent (RLV) detectors to suit the needs of your application. We use our proven standard detector models as the heart of our RLV detectors. Each RLV detector is retrofitted with a 2-inch schedule 80 relief line vent fitting and potted electronics. The detector can sense gas in your relief line vent header, regardless of whether it is coming from a weeping valve or during a release due to system overpressure.

• Bright LED display, indicating NH3 concentration in Real Time
• Capable of sensing ammonia at very low concentrations to catch weeping valves
• Annual calibration requirement, reducing maintenance costs
• RLV fitting mounted on back of detector or configured as remote sensor

The LBW-Watchman-RLV detector is manufactured in the USA and comes with our standard three-year limited warranty.
