Cryogenic O2 pant (>99%)
Cryogenic oxygen plant or called air Separation Unit (ASU) can generate only oxygen, or generate both oxygen and nitrogen in gas or liquid form. The working principle of it is that dry saturated air with purifications to remove moisture, impurities entering the lower tower becomes liquid air as it continues to be cryogenic. Physically air is separated, and high purities oxygen and nitrogen are obtained by rectifying in fractionating column according to different boiling points of them. Rectifying is the process of multiple partial evaporation and multiple partial condensation. This kind of cryogenic oxygen plant has main components including rectifying tower or cooling tower, air compressor, pre-cooler, turbine expander etc. Flow chart: We can design and produce according to our customers’request and the climate in different countries. About our Service : About us : This is Hangzhou Nuzhuo Group , we are a manfacturer for PSA-oxygen , nitrogen ,VPSA, Cryogenic Air separation unit /plant /equipment. FAQ:Different types have different components and maintenance cost. For the same type different sizes and performances are also different. Take PSA oxygen generators for example, the maintenance parts mainly include air compressors, filters, and oxygen compressors if any.
Firstly if overly water, oil vapor, dust enter some parts absorbent like molecular sieve, these parts shall have to replaced completely. Subsequently this will affect performances of machines. So regular maintenance is an important work to do, like replacing filter elements every 2,000 -4,000 hours.
It depends on how much gas required and its quality requirements. Different types have their advantages.
Generally electricity power is required by each system, and some requires cooling water also. The power consumption varies from small to big sizes. For unit power consumption, normally the bigger size the less unit power consumption.
Different type has different normal pressures from 0.5 to 20bar. With compressor added any desired pressures are available. For example PSA nitrogen generator gets 1-8bar, or 150bar with added nitrogen compressor.
O2 range: 90%-99.9%. N2 range: 95%-99.9999%
Yes available. By touching screen all parameters are regulated.
Following the manual and notice to do operation is safe. Very rare there are blast for filling cylinders, unless wrong operations or poor quality of high pressure parts.
Generally available. We can design and manufacture as per your country's law or regulation, like US standards ASME, CE standards PED etc.
Yes available. Complete monitoring of working parameters like flow, purity and alarms/reminders are within our capability. We have cloud monitoring to utilize cloud technology for the system.
Yes it is. Engineers can be sent to customers site for installation, startup, commissioning, training. Service charge USD150/day excluding travel cost.
Different types have different time. PSA unit takes normally 3-7 days to finish installation, startup, commissioning, training. Cryogenic unit takes longer time, generally a month. It also has to do with site preparation conditions and workers proficiency.
