Though the initial investment is high, they are critical for ensuring the continuity and quality of high-end industrial production.
Key Factors Affecting Costs
Oxygen Production Capacity
Oxygen production capacity is a key factor in determining price. The larger the capacity, the greater the compression and processing power required, which leads to higher costs. For example, equipment producing 50 cubic meters of oxygen per hour can cost 50%-100% more than a 10 cubic meter unit due to the increased complexity of core components, supporting equipment, and systems.
Oxygen Purity
The demand for high-purity oxygen drives up the price of oxygen generators. For example, when the purity increases from 95% to 99%, the price may double to cover the high-end purification equipment, process development, and monitoring systems. Businesses must balance the increase in purity with the associated cost.
Altitude
At higher altitudes, the air is thinner, requiring larger capacity compressors. As a result, the cost of equipment increases.
Ambient Temperature
Ambient temperature can impact the equipment. For example, in environments as cold as -30°C, special treatments are necessary, such as adding antifreeze to compressors, incorporating air dryers, filters, heating tapes for drainage systems, and installing heaters in air buffer tanks.
Technology and Process
Advanced technology improves equipment performance and energy efficiency, resulting in higher initial prices but providing long-term cost savings and increased efficiency. Compared to traditional equipment, the price may be 10%-20% higher, and businesses should consider the total lifecycle cost and benefits.
Brand and Manufacturer
Well-known brands like Ingersoll Rand and Siemens often come with a 10%-20% price premium due to their investments in technology development, quality control, reputation, and after-sales service. These brands reduce the risk of production interruptions and are a trusted investment.
Custom Requirements and Additional Features
Meeting special requirements and incorporating additional features can increase costs by 10%-15%, depending on the complexity of customization. While these features enhance performance, they also add to the procurement and maintenance costs.
Accessories and Auxiliary Equipment
The price of industrial oxygen generators is significantly influenced by the need for additional equipment and accessories. These include:
Air Compressor
A key component of the oxygen generator, providing compressed air. The cost depends on the capacity, type (e.g., screw-type, piston-type), brand, and energy efficiency, typically ranging from $2,000 to $15,000. Large-capacity, energy-efficient brand compressors are more expensive, while smaller, basic models are cheaper.
Air Storage Tank
Used for storing compressed air, available in dry and wet versions. Dry tanks store dry air to prevent moisture and impurities from affecting the system, while wet tanks are used to store air with higher humidity in environments where humidity control is less critical. The price of storage tanks depends on capacity and material, typically ranging from a few hundred dollars to several thousand dollars.
Air Filter
Removes dust and impurities from the air to prevent damage to equipment. Prices depend on filtration accuracy, material, and size, usually ranging from a few hundred to several thousand dollars. High-precision, long-lasting filters tend to cost more.
Dryer
Reduces moisture in the air to prevent corrosion and maintain oxygen purity. Prices typically range from $1,000 to $8,000, depending on drying principles, processing capacity, and brand.
Oxygen Storage Tank
Used to store oxygen and ensure a stable supply. Prices are affected by capacity, material, and craftsmanship, typically ranging from $1,500 to over $10,000. Larger-capacity, stainless steel tanks tend to be more expensive.
Oxygen Booster
Used to increase the pressure of oxygen to the required level for different applications. When oxygen needs to be filled into oxygen cylinders to a pressure of 150 bar or 200 bar, or in equipment with a pressure greater than 6kg, an oxygen booster is required. The price of oxygen boosters varies depending on boosting capability, technology level, brand, and associated equipment, typically ranging from several thousand dollars to tens of thousands of dollars.
Maintenance and Operational Costs
While the initial purchase price is important, it is equally essential to consider long-term maintenance and operational costs. These include replacement of consumables, energy consumption, and equipment upkeep. Power consumption is related to equipment power and operating time, so maintenance and operational costs should be evaluated comprehensively.

If a $40,000 industrial oxygen generator is invested, the initial investment could be recouped in about 2.5 to 3 years. Long-term operating costs are mainly related to maintenance and electricity consumption, offering a clear cost advantage over bottled oxygen. On-site generation ensures a stable oxygen supply, controlled purity, and the flexibility to adjust output according to demand.
Cost Breakdown of On-Site Oxygen Generation Systems
Unlike bottled oxygen supply, the cost structure of on-site oxygen generation systems is more complex and mainly covers the following aspects:
- Electricity Consumption: This primarily comes from the air compressor, cooling system, and oxygen generator. The larger the compressor power and the longer the operating time, the higher the electricity costs. For example, a 50m³/h oxygen generator with a 75kW compressor would have an electricity cost of approximately $7.5 per hour. If operated for 2,000 hours annually, the total electricity cost would be around $15,000.
- Labor Costs: Due to the high level of automation, labor costs are relatively low, typically requiring only periodic inspections and maintenance, with annual costs ranging from $1,000 to $2,000.
- Equipment Maintenance Costs: This includes the replacement and calibration of components such as filters, adsorbents, valves, and instruments. For example, the air filter needs to be replaced every 2,000 hours, costing around $100 to $500; the molecular sieve needs to be replaced every 5-8 years, costing around $5,000 to $8,000. The annual maintenance cost is estimated to be between $5,000 and $10,000, depending on the equipment brand, quality, and operating environment.
