Recently, the PSA medical oxygen generator independently developed by GNEE has completed the mass production of 10 units, which were successfully loaded and shipped to 3 general hospitals and children's specialist hospitals in Munich (Germany), Paris (France) and Seoul (South Korea). The exported psa oxygen plant for hospital (hospital-specific PSA oxygen generation equipment) faced numerous challenges from R&D to mass production. To meet the stringent requirement of "720 consecutive hours of trouble-free operation" specified in the EU IEC 60601 Medical Electrical Equipment Standard, the R&D team spent 6 months optimizing the adsorption tower structure, increasing the molecular sieve packing density by 15%. Meanwhile, they overcame the noise control problem during equipment operation: by installing composite sound insulation cotton and shock-absorbing bases, the equipment's operating noise was reduced to below 52 decibels, meeting the ward-level mute standard for hospitals. Ultimately, with a stable oxygen purity of 93%±3%, oil-free process design and comprehensive emergency protection system, the equipment successfully obtained EU CE certification and South Korean KFDA certification, becoming the preferred solution for overseas medical institutions to enhance their independent oxygen supply capacity. The single-unit oxygen output of the equipment ranges from 5 to 50 Nm³/h, which can be flexibly configured according to the number of hospital beds. Among them, the 10 Nm³/h model customized for a children's specialist hospital in Seoul, South Korea, has a specially optimized operation interface, supporting Korean-English bilingual switching and one-key emergency oxygen supply mode.

"Traditional liquid oxygen supply is restricted by transportation and storage. Last winter's cold wave caused an interruption in liquid oxygen transportation, and the emergency oxygen supply in our hospital was once urgent," said the procurement representative and logistics director of a hospital in Munich, Germany. "This pressure swing adsorption oxygen generator adopts psa technology for oxygen generation, which can be directly connected to the hospital's central oxygen supply system. Each unit is equipped with a 150bar high-pressure cylinder filling device, which can automatically complete the reserve of oxygen cylinders during the low oxygen consumption period at night. A single unit can fill 40 cylinders per day, fully meeting the emergency needs. More importantly, its operating cost is only 68% of that of liquid oxygen supply. After putting it into use, our hospital's monthly oxygen expenditure has decreased from 120,000 euros to 82,000 euros, showing significant long-term use benefits." The director also mentioned that the equipment's remote operation and maintenance function is particularly practical. Through the intelligent monitoring platform developed by GNEE, hospital engineers can real-time check 12 core parameters such as oxygen purity and molecular sieve activity. The platform can also predict the need for consumable replacement 7 days in advance, greatly reducing the risk of equipment downtime.

As a professional psa oxygen plant manufacturer (PSA oxygen generation equipment manufacturer), GNEE provides a full-life-cycle service for this export order. To meet the cleanliness requirements of European hospitals, all equipment undergoes 3 rounds of sterile purging and 24-hour airtightness testing before leaving the factory, ensuring no impurity residues in the gas transmission pipeline. The on-site service team completes installation and commissioning within 48 hours after the equipment arrives, and conducts a 3-day practical training for medical staff, covering 10 core skills including daily equipment operation and emergency troubleshooting. In addition, GNEE has established a European Service Center in Düsseldorf, Germany, stockpiling common spare parts such as adsorbents and solenoid valves. It promises to respond to maintenance requests within 24 hours and complete fault handling within 48 hours, completely resolving the after-sales concerns of overseas customers. Currently, all 10 units have been put into trial operation in hospitals, and the operation data shows that the oxygen purity fluctuation is always controlled within ±0.5%, fully complying with medical standards.

In addition to PSA Oxygen Generators, we also produce VPSA Oxygen Generators, storage tanks, heat exchangers and other products. If you are interested in VPSA Oxygen Systems or other products, please feel free to send an email to info@gneeheatex.com. We will be very happy to serve you.
