All the benefits of pressure has two, one is to reduce the impact of gas molecular sieve is two. To improve The utilization rate of compressed air pressure. The couple inequality process more reasonable, scientific, mature, the direct effect is to improve nitrogen recovery, gas production increased, the indirect effect is to reduce the energy consumption of 30%. 2. easy installation, compact structure, integral skid mounted, small area without the need for infrastructure investment, less investment. 3. high quality carbon molecular sieve adsorption large capacity, high compressive strength, long service life. The normal operation of the service life of up to 10 years. 4. other than nitrogen more economic and technical indicators: nitrogen flow rate: 5-3000Nm3/h nitrogen purity: 95%-99.9995% nitrogen pressure: 0. 6-0.0.8Mpa: = -40 C (dew point pressure) economic and environmental protection, PSA technology is a simple and convenient method for preparing nitrogen, using air as raw materials, energy consumption is only air compressor energy consumption, with low operation cost, low energy consumption, high efficiency advantages. 1. mechanical and electrical integration design and implementation of automatic operation of imported PLC control automatic operation. The nitrogen flow pressure purity adjustable and continuous display, set pressure, flow rate, purity alarm and remote automatic control and measurement, realizes unattended operation. The advanced control system makes the operation more simple, can realize the unattended and remote control. System, and can be used for real-time monitoring of various working conditions, so as to ensure the gas purity, flow stability. 2. high quality components is to ensure stable and reliable operation of pneumatic valve, solenoid pilot valve and other key parts imported configuration, reliable operation, fast switching speed, service life of up to millions of times, low failure rate, convenient maintenance low maintenance cost, low purity nitrogen. Nitrogen automatic emptying 3. unqualified automatic emptying system starting early, after reaching the targets. The purity of 4. aspirated ideal range of nitrogen purity is easy to adjust according to the needs of users in 79% ~ 99.99% between the adjusted, plus Purification technology is unique in the series after nitrogen purification, high purity nitrogen can be obtained. 99.9995% cycle process of 5. unique system of valve wear is reduced, prolong the service life of equipment and reduce the cost of maintenance. The HTH type hydrogen nitrogen purification device features: under the action of a catalyst, nitrogen with the system through a small amount of hydrogen reaction, removing the residual oxygen, in the removal of excess hydrogen, purified by adsorption dryer in precision filter, the removal of nitrogen in water and dust, impurities, high purity nitrogen. High purity nitrogen technical index is up to O2 = 2PPm H2 = 3PPm RDN Carbon supported nitrogen purification equipment series features: this series of products using carbon supported catalyst deoxidation, without consuming hydrogen source. More oxygen to form carbon dioxide and nitrogen, then the pressure swing adsorption process for removal of carbon dioxide and water, high purity nitrogen obtained after filtration, the main technical parameters of high purity nitrogen technical index is up to O2 H2 = 3PPm = 4PPm = -60 C: dew point gas purity: 99.9995% point C = -60
