Recently, GNEE, a leading enterprise in the global industrial gas equipment manufacturing sector, announced that its customized psa oxygen gas plant developed for a renowned metallurgical enterprise in Munich, Germany, has completed all factory acceptance tests and packaging procedures, and departed from Ningbo Zhoushan Port to the Port of Hamburg, Germany. It is expected to arrive at the destination port within 38 days and be officially delivered to the customer for commissioning and operation. This shipment of the high-purity psa oxygen gas plant is a key achievement of GNEE's deep layout in the European metallurgical oxygen supply market, and also marks that GNEE's Pressure Swing Adsorption Oxygen Systems have been fully recognized by high-end European industrial customers, further consolidating GNEE's position in the global industrial oxygen generation equipment field.
Munich, as an important industrial center in southern Germany, is home to one of Europe's top iron and steel metallurgy enterprises. The enterprise's steelmaking, smelting and continuous casting processes have extremely strict requirements for the purity, stability and continuous supply capacity of industrial oxygen – the oxygen purity needs to be stably maintained at 99.5%, and the oxygen supply capacity must reach 400Nm³/h to meet the production rhythm of the high-efficiency steelmaking workshop. In the past, the enterprise mainly relied on local liquid oxygen suppliers for oxygen supply. However, affected by factors such as the European energy crisis, rising liquid oxygen production costs, and frequent disruptions in cross-border logistics, the enterprise faced problems such as unstable oxygen supply, soaring procurement costs, and potential safety risks in liquid oxygen storage and transportation. To solve these pain points, the enterprise launched a global tender for "localized oxygen generation equipment procurement" in early 2024, aiming to select a set of oxygen generation equipment that meets EU CE certification, low energy consumption, and adapts to the high-altitude and low-temperature characteristics of southern Germany. After multiple rounds of technical demonstrations, on-site inspections and performance tests, GNEE's psa oxygen generator and supporting Pressure Swing Adsorption Oxygen Systems stood out among more than 20 international competitors and became the final supplier.
The psa oxygen gas plant delivered this time is a customized model independently developed by GNEE for the European metallurgical market, which not only inherits the core advantages of traditional psa oxygen generator such as short start-up time, simple operation and low maintenance cost, but also integrates the energy-saving technology of vpsa oxygen plant (Vacuum Pressure Swing Adsorption Oxygen Plant) to further optimize energy consumption and oxygen production efficiency.
The core technical parameters of the equipment fully meet the strict standards of the German metallurgical industry: the oxygen production capacity is stably 400Nm³/h, the oxygen purity is as high as 99.5% (adjustable within 93%-99.7% according to production needs), the unit oxygen energy consumption is only 0.32kWh/Nm³ O₂, which is 28% lower than the average level of similar equipment in the European market. I
n response to the low-temperature environment in Munich in winter (the minimum ambient temperature can reach -5℃), GNEE has optimized the insulation layer and heating system of the equipment's adsorption tower and pipeline, ensuring that the equipment can operate stably without being affected by low temperatures.
At the same time, the vpsa system for oxygen intelligent control module equipped in the equipment supports real-time monitoring of key parameters such as oxygen purity, pressure and flow rate, and can automatically adjust the operation mode according to the actual oxygen demand of the steelmaking workshop, realizing "on-demand oxygen production" and further reducing unnecessary energy consumption.
The successful shipment of the psa oxygen gas plant to Munich is an important milestone for GNEE to expand its business in the European metallurgical market. As a high-end market for global industrial gas equipment, Europe has extremely high requirements for equipment technical standards, environmental protection performance and after-sales service. The recognition of GNEE's Pressure Swing Adsorption Oxygen Systems by German metallurgical customers is not only due to the independent innovation of core technologies (such as high-efficiency molecular sieve regeneration technology and intelligent energy consumption optimization algorithm), but also to GNEE's in-depth insight into the needs of the European market – the psa oxygen generator and vpsa oxygen plant series products developed by GNEE fully comply with the EU's "carbon neutrality" policy requirements, with low carbon emissions and high energy efficiency, which can help European industrial customers reduce their carbon footprint while controlling production costs.
