NH3 detection scheme for cold storage

In recent years, safety accidents caused by liquid ammonia leakage in cold storage have occurred frequently, and the safety of cold storage has gradually gained public attention.
On February 8, 2012, Nanjimen Cold Storage, which experienced two consecutive ammonia leaks within six months, was shut down
On December 28, 2012, an ammonia gas leakage accident occurred at Shengao Cold Storage in Jishu Town, Jinxiang County
On April 1, 2013, an ammonia leak occurred in the cold storage workshop of Jinluo Meat Products Co., Ltd. (hereinafter referred to as Dezhou Jinluo) in Linyi County, Dezhou, resulting in more than 40 employees being poisoned and hospitalized.
On March 23, 2013, an ammonia leak occurred in an enterprise in Jiangbei District, Ningbo City
On April 17, 2013, an ammonia leak occurred in a company in Hainan Province
On April 17, 2013, an explosion occurred at a fertilizer plant in Texas, USA, caused by a leak of anhydrous ammonia (liquid ammonia)
On June 3, 2013, an explosion and fire caused by the leakage of liquid ammonia from Baoyuanfeng Poultry Processing Plant in Mishazi Town, Dehui City, Jilin Province, resulted in the death of 120 people.

The AG series toxic gas detector and alarm control host of Nanjing Aiyi Technology Co., Ltd. can effectively detect NH3 and send the on-site gas concentration signal to the central control alarm control host, reminding the on-site duty personnel. The host can also implement linkage spray system, cut-off valves, etc., effectively preventing accidents such as NH3 poisoning and explosion.

1. The gas detector can be optionally equipped with a display screen, sound and light alarm, etc., to flexibly meet on-site needs;
2. The gas alarm control host can be linked to on-site valves, sprinkler systems, etc., effectively eliminating safety hazards;
3. The gas detector is subjected to anti-corrosion treatment as a whole, and the key components are made of 316L stainless steel material to ensure its service life and accuracy in various environments.
