Cool Air Inc. offers a full line of relief line vent (RLV) detectors to suit the needs of your application and 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, potted electronics, and robust 0-1000 ppm solid-state sensor. The detector is capable of sensing any ammonia in your relief line vent header, regardless if it is coming from a weeping valve or during a release due to system overpressure.
