CAPABILITIES AND INDUSTRIAL MAINTENANCE ON OXYGEN AND NITROGEN COMPRESSORS.
In sectors where the constant availability of high-pressure gases is key to guarantee efficient and safe processes and/or quality end products, the installation of oxygen and nitrogen compressors (or boosters), on site, allows to optimize their storage and use, ensuring a constant supply adapted to the specific needs of each company.
What is an Oxygen or Nitrogen Booster?
A booster is a high-pressure compressor designed to increase the pressure of oxygen or nitrogen up to 200 bar. Gurpea Green Tech's boosters, which incorporate proprietary technology, operate with a two-stage compression process, in which the gas enters at a pressure of 5-6 bar and, after a controlled compression and cooling process, is stored in cylinders at an optimum pressure for use, which varies according to the type of customer, product or application.
The most valued in the market: Customized design and close maintenance service.
En el mercado de los compresores de oxígeno y nitrógeno en España, Gurpea Green Tech is positioned as, if not the only one, the main national manufacturer with its own engineering and technology, and with the capacity to offer a close and highly specialized technical service. This allows us to guarantee our customers:
1. Customized and adaptable design of the O2/N compressor.
The specific requirements of each customer are the ones that mark the design, to measure, of the oxygen or nitrogen compressors, adapting to the different capacities needed, according to the flow rate demanded.
- Determining Factors in Booster Capacity.
The required capacity of a booster depends on several key factors:
- Consumption Demand: The amount of gas required per unit of time directly influences the compressor capacity. Industrial processes with high demand require larger capacity boosters to maintain adequate pressure and flow.
- Inlet and outlet pressure: The initial gas pressure and the desired outlet pressure determine the required compression ratio, affecting the selection of the right oxygen/nitrogen compressor.
- Duty Cycle: The frequency and duration of booster use influences the required capacity. Continuous operations demand equipment with higher robustness and capacity to avoid overloads.
- Environmental Conditions: Factors such as temperature and humidity can affect booster performance, being necessary to consider these variables in the design and selection of the equipment.

- Which flow rate should I choose? Main recommendations.
The choice of the type of flow rate required for an oxygen compressor depends on several technical, operational and plant design factors. These factors are related to the required oxygen production capacity, the characteristics of the system and the specific needs of the process or application.
If you want the selection of the flow rate of your Oxygen or Nitrogen compressor to be optimal and efficient, we recommend:
- Perform an oxygen demand analysis (volume and pressure) for your specific application. The compressor flow rate must be able to supply enough compressed air to meet the plant's production capacity. For example, a plant producing 10 Nm³/h of oxygen will require a compressor with a flow rate proportional to the air needed to generate that volume, considering typical oxygen to air ratios (21%).
- Consult the oxygen generator's technical specifications for compressed air requirements.
- Consider a safety margin of 10-20% to cover possible increases in demand or losses in the system. 4. Ensure that the compressor can operate efficiently in local environmental conditions. In high altitudes or hot environments, air density decreases, which affects compressor performance. In these cases, a compressor with higher capacity is needed to compensate.
- If demand is variable, evaluate a variable speed compressor (VSD) to optimize energy consumption.
If the oxygen consumption is constant, a fixed flow compressor can be chosen.
Within the range of O-NB Booster of Gurpea Green Tech, there are 6 models, depending on the flow rate demanded. All these oxygen / nitrogen compressors reach 30 Bar pressure.
2. Industrial Maintenance Service nearby.
Unlike other international providers that depend on external and inaccessible technical support, at Gurpea Green Tech we provide close technical assistance anywhere in Spain, ensuring the good condition of the systems and the continuity of their operation, reducing the resolution times of incidents that may arise.
- Types of industrial maintenance required on Oxygen and Nitrogen Compressors.
Proper maintenance of boosters is crucial to ensure their optimum performance and prolong their service life. The most common types of maintenance include:
- Preventive Maintenance: Consists of scheduled interventions to inspect, clean and replace components before they fail. Typical tasks include checking filters, lubricating moving parts, draining condensate in tanks, adjusting belts and pulleys, and checking cooling systems, operating pressures and oil level. The periodicity is usually monthly or quarterly, depending on the hours of operation and the manufacturer's recommendations.
- Corrective Maintenance: It is performed when an unexpected failure occurs, requiring repairs or replacement of defective components (valves, pistons...). Although it is less desirable than preventive maintenance, it is essential to have a technical service nearby to minimize downtime.
- Predictive Maintenance: Uses continuous monitoring techniques to anticipate failures before they occur, based on the analysis of operational data. This approach allows planning interventions more efficiently and reducing costs associated with unscheduled shutdowns. Among the assistance usually required in this type of maintenance are vibration analysis, thermography to identify hot spots and oil analysis to detect contamination or wear.
The implementation of a preventive maintenance program in production plants can improve productivity by up to 25%, reduce maintenance costs by 30% and extend the useful life of machinery and equipment by up to 50%.
- Maintenance planning according to the compressor flow rate.
Yes, the scheduling and timing of maintenance can be significantly affected by compressor flow rate and other factors related to compressor workload. How does the flow rate of the oxygen or nitrogen compressor impact maintenance?
- Higher flow rate = higher workload:
High-flow compressors tend to operate at higher intensity and for longer periods of time, which accelerates the wear of components such as filters, valves, seals, and lubricants. This means that preventive and predictive maintenance must be performed more frequently.
- Condensate accumulation:
The higher the flow rate, the more condensate is generated (especially in systems without a good dryer). This may require more frequent draining to avoid problems such as corrosion or contamination.
- Operating temperature:
High flow compressors tend to generate more heat. This can affect the service life of the oil and internal components, necessitating stricter monitoring of lubricant temperature and quality.
- Effect on filters:
The high flow rate increases the rate at which air and oil filters become clogged. Therefore, filter replacement intervals should be shorter.
- Recommendations to adjust the periodicity according to the flow rate:
- For low flow compressors (≤50 m³/h):
- Preventive maintenance every 6 months.
- Basic monthly overhaul (visual inspection, condensate drainage).
- Annual predictive analysis (vibrations, oil).
- For medium flow compressors (50-200 m³/h):
- Preventive maintenance every 3-4 months.
- Basic check-up every two weeks.
- Semiannual predictive analysis.
- For high flow compressors (≥200 m³/h):
- Preventive maintenance every 1-2 months.
- Basic weekly check-up (filters, leaks, drains).
- Quarterly predictive analysis.
The right choice of oxygen or nitrogen boosters/compressors, together with a well-structured maintenance program, is essential to ensure efficiency and safety in industrial processes.
