What is the working principle of the cryogenic air separation unit?

It uses cryogenic rectification to condense air into liquid and separate components based on evaporation temperature. A two-stage rectification tower obtains pure nitrogen and pure oxygen simultaneously, with options to extract liquid oxygen and nitrogen from the main cooling sides.

What core components are included in the system?

Key components include the Cold Box, Purifier, Air Compressor, Turbo Expander, Fractionating Column, and Siemens imported Instrument and Electric Control System.

AI-Powered supplier vetting

SummaryThe supplier demonstrates broad manufacturing coverage, with seven equipment series, more than 800 specifications and models, 12 production lines, in-stock capability, and OEM service for well-known brands. It supports minor through full customization and has substantial export experience, including 23 experienced export-trade staff and 12 years of exporting. ISO9001, ISO45001, ISO14001 and CE certifications are reported. Quality assurance exists, but finished-product inspection is performed by packing staff, and corrective-action and complaint procedures lack written records. R&D capability is limited by two engineers, no available SDK, and no new products launched last year. No valid manufacturing-capacity contract with related subcontractors, overseas warehouse, or overseas showroom is reported. Customer-case evidence is limited: no Fortune 500 cooperation is stated, although OEM service for well-known brands and repeat buyers of 30%–50% are reported.

Supplier typeThe supplier is an equipment manufacturer offering OEM services for well-known brands. Its portfolio covers seven equipment series and more than 800 specifications and models, indicating a broad industrial product scope.

CertificationsThe supplier reports ISO9001:2015, ISO45001:2018 and ISO14001 management-system certificates, plus CE product-certification capability. These are explicit certification holdings or capabilities supporting quality, occupational safety, environmental management and market access.

R&D capabilityInnovation evidence is limited: the supplier has two R&D engineers, no available SDK, and launched no new products last year. The absence of new products and SDK availability indicates constrained demonstrated innovation output, although the slices do not explicitly establish a complete lack of R&D capability.

Production capacityProduction scale and range are supported by 12 production lines, seven equipment series, more than 800 models, 36 qualified service-capability suppliers, in-stock capacity, and stated lead-time options. However, there is no valid manufacturing-capacity contract with related subcontractors, and the lead-time entry is internally unclear; the explicit manufacturing resources nevertheless support production capability.

Customization capabilityThe supplier explicitly offers minor customization, full customization, flexible customization, customization from designs, and customization from samples. This directly demonstrates broad customization support across multiple input formats and complexity levels.

Product Q&A

Q:How can I get the quotation fast?

Please provide: 1) O2/N2 Production capacity (Nm3/h); 2) O2/N2 Purity (%); 3) O2/N2 Discharge pressure (Bar); 4) Need for simultaneous production or switching; 5) Local Voltages and Frequency (V/PH/HZ); 6) Application industry and country.

Q:What is your term of payment?

T/T 30% in advance and T/T 70% balance paid before shipment.

Q:What is the difference between PSA and Cryogenic plants for producing Oxygen/Nitrogen?

PSA uses molecular sieve adsorption to separate air. Cryogenic rectification compresses and cools air to liquefy it, then separates oxygen and nitrogen based on boiling point differences. Cryogenic method is currently the most widely used and dominant technology for high-purity production.

Q:What is ASU in an oxygen plant?

ASU stands for Air Separation Unit. It is a plant that utilizes the distinct properties of air components to produce highly purified oxygen, nitrogen, and sometimes argon.

Q:What are the main applications of oxygen and nitrogen?

Oxygen is used in steelmaking, chemical fertilizers, metal cutting, defense (rocket accelerants), and medical first aid. Nitrogen is used as protective gas in metallurgy/electronics, in fertilizer production, for superconducting materials, food preservation, and as a medical refrigerant.
