Due to the fact that nitrogen is colorless and odorless, and can cause harm to the human body if inhaled, workers must pay close attention to the following precautions to ensure safe maintenance.

Molecular sieves, the core component of PSA oxygen generators, are porous materials that can screen substances at the molecular level. Although it can be used to physically separate oxygen and nitrogen in the air, its disadvantage is that it is susceptible to moisture and directly affects the quality of the output gas after being damp. Therefore, when storing molecular sieves, be sure to pay attention to the following issues.

Dew point meter is required to measure the dew point of compressed air. There are two common instruments for measuring the dew point of compressed air. Their respective characteristics are as follows:

In the process of producing oxygen in the PSA oxygen generator , there is an energy consumption indicator called kw•h m3, which refers to how much electrical energy (kw•h) is consumed to produce 1 Nm3 of oxygen (standard state). Users can calculate this value to understand the performance of an oxygen generation system.

Although the oxygen generator room has strict measures and regulations for fire prevention and control, there are also some ways to deal with fire.

​In the PSA nitrogen production system, in order to protect the air compressor better, ensure stable compressed air pressure, and ensure that the loading and unloading of the air compressor is within a reasonable range, CAN GAS recommends an air buffer tank after the air compressor.

CanGas® PSA oxygen generation system CFS series oxygen generation equipment can not only meet the requirements of on-site oxygen production, but also has oxygen filling function.

In the PSA nitrogen generator, there is a concept to measure the efficiency of the equipment called "air-to-nitrogen ratio ". It refers to the ratio of the dry compressed air volume consumed by the nitrogen generator to the product nitrogen volume. Assuming that the "air-to-nitrogen ratio " is 3.5, it means that every 3.5 Nm3 of air can produce 1 Nm3 of nitrogen.

In PSA nitrogen (oxygen) equipment, pressure gauges are common. We need to use these instruments to detect, measure, observe, and calculate the pressure in the equipment, or through the associated settings of the instruments to achieve automatic control of the equipment and the realization of functions such as control, alarm and signal transmission.

Medical oxygen is a gas commonly used in medical facilities. In terms of properties, it is a drug. It is clearly stipulated in the National Pharmacopoeia that the purity of medical oxygen should be above 99.5%. What should be used to produce oxygen with such high purity and pharmaceutical properties?
