Precautions for Using Winter Industrial PSA Oxygen Generators—These Key Points Must Be Remembered!

With the sharp drop in winter temperatures and an increase in rainy and snowy weather, low-temperature environments not only affect the operational efficiency of industrial PSA oxygen generators but may also damage equipment components, increasing the risk of malfunctions. To ensure the stable, safe, and efficient operation of oxygen generators, we have compiled the following key usage guidelines tailored to the characteristics of winter weather.

I. Before powering on: Conduct a comprehensive inspection to eliminate potential hazards caused by low temperatures.

A comprehensive inspection before starting up equipment in winter is crucial for preventing startup failures. Particular attention should be paid to the ambient temperature, the condition of equipment components, and the readiness of auxiliary systems. First, ensure that the ambient temperature in the equipment operating environment is no lower than 0°C. If the ambient temperature is too low, turn on the workshop heating system in advance to prevent frost from forming inside the equipment’s pipelines and valves due to the cold. Next, inspect the intake air filter. In winter, dust and moisture in the air tend to condense on the filter element; therefore, clean any impurities from the surface of the filter element to ensure unobstructed airflow. Also, check whether the filter element has become hardened or cracked due to low temperatures. If any damage is found, replace it promptly. In addition, inspect the hydraulic and lubrication systems. Low temperatures can increase the viscosity of hydraulic oil and lubricating oil, reducing their fluidity. Make sure that the oil levels are sufficient and that the oil type meets the requirements for winter operation. If the oil has not been replaced with a winter-specific formulation, do so immediately to ensure adequate lubrication of all components.

II. Running: Real-time monitoring, stable operating parameters

During the operation of an oxygen concentrator, it is essential to monitor various operational parameters in real time and promptly address any parameter fluctuations caused by low temperatures. First, monitor the intake air temperature and pressure: Use the equipment’s control system to keep track of the intake air temperature and ensure it remains within the optimal range. If the intake air temperature drops too low, activate the intake air preheating device. At the same time, pay close attention to the stability of the intake air pressure to prevent pipe contraction due to low temperatures from affecting the intake pressure. Second, monitor the oxygen purity and production rate. Low temperatures can impair the adsorbent’s adsorption performance, potentially leading to reduced oxygen purity and lower output. Therefore, regularly take samples to test the oxygen purity. If the purity falls below the set standard, promptly adjust parameters such as adsorption time and pressure; if necessary, inspect the condition of the adsorbent inside the adsorption tower. Third, monitor the temperatures of equipment components, with particular focus on the operating temperatures of power components such as the compressor and vacuum pump. In winter, after the equipment is started, it takes longer to warm up. Avoid running the equipment at high load for extended periods under low-temperature conditions to prevent accelerated component wear.

3. After shutdown: Follow standard operating procedures and take proper frost-protection measures.

After a winter oxygen concentrator is shut down, improper protection can easily lead to issues such as pipe freezing and rupture, as well as component damage. Therefore, it is essential to follow the prescribed operating procedures strictly. First, shut down the equipment step by step according to the operation manual, avoiding sudden shutdowns that could cause abrupt pressure changes. Second, promptly drain any accumulated water from inside the equipment and its pipelines—this includes drainage ports on air intake filters, condensate separators, and bottom drain valves. Thoroughly draining all standing water will prevent low nighttime temperatures from causing ice formation and subsequent pipe bursting. For equipment that will be idle for an extended period, close the air intake valve and the outlet valve, disconnect the power supply, and cover the main unit with a dustproof cover. Additionally, wrap and insulate critical components such as valves and instruments to protect them from direct exposure to rain, snow, and cold air. Furthermore, after shutdown, clean the equipment’s surface of dust and accumulated snow to keep it clean and dry.

4. Daily Maintenance: Strengthen upkeep to extend equipment lifespan.

In winter, the harsh environmental conditions necessitate increased frequency of daily maintenance and upkeep for oxygen concentrators. On the one hand, we should increase the frequency of filter element replacements. In winter, dust and moisture tend to clog filter elements easily; therefore, it is recommended to inspect the intake filters and precision filters every two weeks and replace them promptly according to the degree of contamination. This will prevent increased intake resistance caused by clogged filters, thereby maintaining the equipment’s operational efficiency. On the other hand, regular inspections of sealing components are essential. Low temperatures can cause rubber seals to shrink and age; thus, it is crucial to check the equipment’s pipeline connections and valve seals for any signs of air leakage. If any damage or aging of seals is detected, they should be replaced immediately to ensure the equipment maintains proper sealing performance. Additionally, regularly inspect the equipment’s control system, clean dust from the control panel, and verify that all wiring connections are secure, thus avoiding circuit failures caused by low temperatures and high humidity.

The stable operation of winter industrial PSA oxygen generators depends on standardized operation and meticulous maintenance. By strictly adhering to the above precautions—performing thorough pre-startup inspections, closely monitoring operations during runtime, taking proper protective measures after shutdown, and carrying out regular daily maintenance—you can not only enhance the equipment’s operational efficiency but also effectively extend its service life and ensure the smooth progression of the production process. If you encounter complex malfunctions during operation, it is recommended that you promptly contact the manufacturer’s professional technicians for repair; under no circumstances should you attempt to disassemble the equipment yourself.
