Background：
Nowadays, with the continuous increase of the refrigeration industry, ammonia gas alarms are also favored by the people. All links of agricultural and livestock products from harvesting, processing to commodity sales have been refrigerated. By slowing down the respiration and metabolism of fruits at low temperature, it can prevent decay. The purpose of prolonging the storage period. Generally, the cold storage is mostly refrigerated by a refrigerator, and a liquid with a very low vaporization temperature (ammonia or freon) is used as a coolant. It evaporates under low pressure and mechanically controlled conditions, absorbing the heat in the storage. So as to achieve the purpose of cooling down. Ammonia is a colorless gas with a strong pungent odor, so the freezer needs to be equipped with an ammonia gas alarm device.
Why should an ammonia gas alarm be installed in the freezer?
Ammonia is lighter than air. Long-term exposure to ammonia gas may cause symptoms such as skin pigmentation or finger ulcers in some people. After being inhaled into the lungs, ammonia gas easily enters the blood through the alveoli, binds with hemoglobin, and destroys the oxygen transport function. After inhaling a large amount of ammonia in a short period of time, tears, sore throat, cough, bloodshot sputum, chest tightness, and difficulty breathing may occur. May be accompanied by dizziness, headache, nausea, vomiting, fatigue and so on. In severe cases, pulmonary edema and adult respiratory distress syndrome may occur. Respiratory irritation may also occur. Ammonia gas alarms include portable ammonia alarms and fixed ammonia alarms. The portable ammonia gas alarm is easy to carry and can be turned on at any time to detect the concentration of ammonia gas.
Fixed ammonia gas alarm is composed of gas detector and gas controller. Gas alarm controllers are generally wall-mounted and installed in duty rooms and lounges where people are present and easy to observe. Receive the ammonia gas concentration detected by the gas detector. And realize the concentration display and sound and light alarm function after exceeding the standard. Linkage with external equipment (solenoid valve, exhaust fan, etc.).
Fixed gas detector, stable performance, sensitive and reliable. With high-precision liquid crystal display, explosion-proof housing, diffusion type or pump suction type. The NH3 detector has the characteristics of flexible use and simple operation. The explosion-proof level of the NH3 sensor is CT6.
