Cold storage ammonia NH3 detection plan

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 HNAG1000 series toxic gas detector and alarm control host of Shenzhen Huoni Aige Technology Co., Ltd. can effectively detect NH3 in low-temperature environments and send the on-site gas concentration signal to the central control alarm control host to remind on-site personnel. The host can also implement linkage spraying system, cut-off valves, etc., effectively preventing accidents such as NH3 poisoning and explosion.

The model is HNAG1000, which uses imported sensors and can detect signals normally even in low temperature environments. The output signal is 4-20mA and RS485, which can be connected to your system. There is also a relay switch that can control equipment such as fans and sprinklers. It has an audible and visual alarm and an alarm sound of about 90 decibels. The host also has an alarm function and can be equipped with an external alarm and an infrared remote control for easy calibration. It has a corrosion-resistant and explosion-proof shell and can be installed in a cold storage without worrying about safety issues

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 fan systems, etc., effectively eliminating safety hazards;

3. The gas detector is subjected to anti-corrosion treatment as a whole, with key components made of stainless steel to ensure its service life and accuracy in various environments.
