second

1. Nitrogen generator for electronic industry (purification device produces high purity nitrogen ≥ 99.9% or 99.99% or 99.999%)

Nitrogen used in electronic industry is generally used for packaging, sintering, annealing, reduction and storage of electronic products. It is mainly used in wave soldering, reflow soldering, crystal, piezoelectric, electronic ceramics, electronic copper strip, battery, electronic alloy materials and other industries. Therefore, according to the different uses, the purity requirements are not the same. Generally speaking, the purity should not be lower than 99.9%, and 99.99% purity can be used. In some cases, nitrogen purification equipment can obtain high-quality nitrogen with purity more than 99.9995% and dew point lower than - 65 ℃.

2. Nitrogen generator for metallurgy and metal processing industry (≥ 99.999%)

It is used for annealing, sintering, nitriding, furnace cleaning and gas purging. Used in metal heat treatment, powder metallurgy, magnetic materials, copper processing, wire mesh, galvanized wire, semiconductor, powder reduction and other fields. Pressure swing adsorption type nitrogen generator produces nitrogen with purity more than 99.9%. High quality nitrogen with purity more than 99.9995% and dew point lower than - 65 ℃ is used for nitrogen purification equipment.

3. Nitrogen generator for food and pharmaceutical industry (≥ 99.5 or 99.9%)

Through sterilization, dust removal, water removal and other treatment, high-quality nitrogen can be obtained to meet the special requirements of the industry. It is mainly used in food packaging, food preservation, drug packaging, drug ventilation, drug transportation atmosphere. The purity of nitrogen is 99.5% or 99.9% by PSA.

4. Nitrogen generator for chemical industry and new material industry (nitrogen purity generally ≥ 98%)

Nitrogen in chemical industry and new material industry is mainly used for chemical feed gas, pipeline purging, atmosphere replacement, protective atmosphere, product transportation, etc. it is mainly used in chemical industry, spandex, rubber, plastic, tire, polyurethane, biotechnology, intermediate and other industries. The purity is not less than 98%.

5. Other use industries

It is also used in coal and other oil fields. With the progress of science and technology and the development of society, the application of nitrogen fertilizer is more and more extensive. The field gas generator (nitrogen generator) has gradually replaced the traditional nitrogen supply methods such as liquid nitrogen evaporation and bottled nitrogen due to its advantages of less investment, low cost and convenient use.
