viii. Ammonia is an efficient refrigerant but its toxicity limits it to industrial applications such as freezing the ice in hockey rinks. Detection system design and output functions are similar with the difference being the CO2 sensor selected, warning setpoints at 0.5% (OSHA 8 hour TWA) and alarm setpoints at 1.0%. Models of Ammonia Gas leak detector and transmitter Few of our models are listed hereunder: In large, open cold storage warehouse rooms where this results in more than 3 sensors in a room, distances can reasonably be relaxed to 50 horizontal feet from a potential leak source, with a minimum of 3 sensors. How Does Litmus Paper Work? Power controller with dedicated branch circuit using Uninterruptable power supply (UPS) backed up by emergency generator to provide 24 hour operation in the event of a power outage. Codes require audio-visual indication inside the compressor room and outside each entrance to the compressor room at 25 ppm. vi. Install vent line sensor utilizing supplied mounting kit. In the compressor room, codes also require shutdown of compressors, pumps, and normally closed solenoid valves at a very high concentration (20,000 ppm is industry standard). Phenolphthalein can indicates the presence of ammonia by changing colors at an alkaline of ~pH 11.6 . More demanding applications such as those in the nuclear industry use even smaller compounds such as tritium which is radioactive & needs specialized equipment. The controller shall be equipped with programmable alarm relays to activate external horn/strobes, exhaust fans, monitoring systems, and shut down equipment. Pharmaceutical isolators can be tested with a small dish of liquid ammonia placed inside the isolator which is then pressurized.

The sensor can detect concentrations as low as 30ppm in the air and is ideally suited to critical safety-related applications such as the detection of ammonia leaks in refrigeration systems and ammonia detection in the agricultural field. i. Section 5 deals with incidents and brings out key learning points. In refrigerated rooms, codes require alarming to a monitored location. All wire runs should be supervised with the controller indicating a fault if communication with a sensor is lost. The Ammonia Gas Detector has high sensitivity to ammonia gas. One 0-250 PPM detector should be located under the normal ventilation fan. The sensor shall have potted electronics to protect circuit board and components. A liquid leak will to the floor and if large enough can cool down a room so quickly that high concentrations are found on the floor with very low concentrations at the ceiling. Test Strip Expiration Dates; Good Today, Dead Tomorrow? Consider installing ammonia detectors in areas where a substantial leak could occur if the facility is not manned 24 hours/day. Locate one sensor below the ventilation fan so it samples airflow from throughout the room when the fan is on. One caveat to keep in mind is that unlike ammonia, CO2 is always present in air, and concentrations can build up to these levels in a facility from sources other than a leak in the refrigeration system. An uninterruptable power supply (UPS) that can run the system for a few minutes during the transition to emergency generator power should be utilized. One controller can support a combination of ammonia and CO2 sensors. It has many important industrial and agricultural uses.
