The price of an integrated nitrogen generator with a built-in compressor varies greatly according to equipment model, nitrogen production capacity, nitrogen purity, configuration level and application scenarios, and the overall market price ranges from thousands to tens of thousands of US dollars. The integrated nitrogen generator integrates air compressor, cold dryer, filter, nitrogen separation host, gas storage tank and control system into one unit, realizing plug-and-play operation, eliminating the need for separate purchase and installation of supporting equipment, with small footprint and simple operation, which is widely used in small industrial processing, food fresh-keeping, laboratory testing and small and medium-sized production scenarios.
Small low-purity integrated equipment with nitrogen production capacity of 1–10 cubic meters per hour and nitrogen purity of 95%–99% is the most cost-effective model, mainly used for ordinary food fresh-keeping, metal anti-oxidation and packaging protection. The price of this type of equipment is mainly between $1,500 and $4,000. The equipment is equipped with a conventional silent compressor and ordinary membrane separation module, with basic automatic control functions, simple structure and low manufacturing cost, meeting the gas demand of low-standard industrial scenarios, and is the mainstream choice for small enterprises and individual processing workshops.
Medium-sized high-precision integrated nitrogen generators with nitrogen production capacity of 10–30 cubic meters per hour and nitrogen purity of 99.9%–99.99% are priced at $4,000 to $12,000. This equipment is equipped with an oil-free silent compressor, multi-stage precision filtration system and high-efficiency PSA adsorption module, with stable operating performance and low energy consumption. It adds intelligent parameter adjustment and fault self-diagnosis functions, which is suitable for electronic processing, precision parts manufacturing and medium-standard food processing scenarios. The price difference is mainly affected by the brand of core components, degree of intelligence and energy-saving configuration.
High-purity industrial-grade integrated nitrogen generators with nitrogen purity above 99.999% and nitrogen production capacity above 30 cubic meters are priced at $12,000 to $30,000. This high-end equipment is equipped with a fully oil-free variable-frequency compressor, deep drying and deoxidation purification system and industrial-grade intelligent control system, with ultra-low dew point and ultra-high purity gas supply, meeting the production demand of new energy batteries, semiconductor and high-precision electronic industries. In addition, customized equipment with special anti-corrosion, explosion-proof and low-temperature resistance functions will have a 20%–50% price increase according to the customization requirements.
It is worth noting that the overall quotation of the equipment includes the host equipment cost, assembly and debugging cost, basic after-sales service cost, etc. Extended services such as on-site installation, long-term maintenance and customized parameter adjustment will generate additional fees. Users can select the appropriate configuration according to their own nitrogen purity, output and scenario requirements to avoid excessive configuration waste or insufficient equipment performance.
