What is the fire protection rating of the nitrogen generator room

The development of cities cannot be separated from the development of industry, and the development of industry cannot be separated from the existence of factories. As long as there are factories, there must be a certain awareness of safety precautions; because in daily life, there are many factors that can cause fires, and a little safety awareness Being lax can lead to accidents. Therefore, our country has made a strict classification of the fire risk of factory buildings. Among them, most manufacturers classify the machine rooms where air separation equipment such as molecular sieve pressure swing adsorption (PSA) nitrogen generators are placed into fire risk E. class.

The so-called fire hazard Category E factories refer to production plants that use or process non-combustible substances at normal temperatures. This type of factory has the lowest fire risk and does not have high fire protection requirements.

Although the machine room in the factory where the molecular sieve pressure swing adsorption (PSA) nitrogen generator is placed does not have high fire protection requirements, when implementing nitrogen production operations, relevant personnel must strictly follow the system's operating procedures and maintain heat dissipation and ventilation in the machine room. good. Regularly inspect and maintain the equipment and instruments in the nitrogen generating machine room. If an abnormality is found, report it for repair in time to ensure that the equipment is working properly.

As part of a comprehensive fire management plan, it's important to consider the right fire suppression method. After prevention and protection, suppression is the last line of defense from damage and destruction. Common types of suppression include gas, chemical foam, water mist, foam deluge, and pneumatic heat.

If you work in a facility with expensive electrical equipment, using a suppression system with water/liquids can result in unnecessary costly damage. Nitrogen (N₂) works by reducing the oxygen level in the space to where (typically below 15%) the fire will extinguish automatically. This is ideal for protecting electronics and machinery, such as air compressors.

Even if water-damaged electronics aren't a concern regarding fire suppression, N₂ can still be beneficial in so-called dry pipe sprinkler systems. Here, N₂ serves as a supervisory gas, filling the pipes rather than water. A dry pipe valve only allows water to enter the pipes when a fire sets off one or more sprinklers. This set-up prevents water vapor and oxygen (O₂) in pipes to cause corrosion and bacteria.
