Stability of PSA nitrogen generation units
Thread Content
May I ask, are the PSA nitrogen generation units produced in China stable nowadays, and prone to failure? We are going to install one with a capacity of 240 Nm3/h. Output 06-0.8mpag. Purity 99.5%. It is used for purging gasoline and diesel. Do nitrogen generation units usually come equipped with gas detectors? Will it give an alarm if the oxygen level exceeds the limit?
PSA nitrogen production is not complicated; domestic systems are sufficient, with nitrogen purity reaching 99.5% or higher. Most of these machines come equipped with a purity meter, and low-purity alarms can be set up both on-site and via DCS. It is advisable to choose branded products
It is a highly mature and stable complete set of equipment; it is important to choose the air compressor carefully.
99.5% purity is not high; it’s not a technical issue at all. Typical nitrogen generation systems are equipped with gas detection devices, which automatically vent unqualified gas outside.
Domestic ones are very stable and rarely malfunction. The nitrogen production devices you mentioned have very low requirements – just the most basic ones, so there’s no need to worry
When it comes to domestic products, people mainly consider the brand as well as the overall configuration of the equipment. It’s not about the absence of faults, but rather the fault rate. Sometimes, the improper selection of a small component can affect the operation of the entire equipment. Also, since there are concerns about equipment issues, a warranty agreement can be signed to specify the location where the equipment will be used, allowing the equipment manufacturer to take those factors into account when determining the specifications. It is also important to choose reputable brand sellers; don’t be tempted by cheap equipment – you get what you pay for, and this should be understood. There are some unscrupulous sellers who, even if you pay the proper price, still provide equipment of poor quality, while other sellers guarantee quality even if it means incurring a loss on that transaction.
