In fields with growing demand for liquid nitrogen such as medical treatment, food, electronics, and biological research, the performance of liquid nitrogen machines directly affects production efficiency, operating costs, and working environments. As a professional manufacturer with over 30 years of experience in air separation and pressure swing adsorption (PSA) technology, Jiangsu Minnuo has created a series of liquid nitrogen machine products with core advantages of high efficiency, energy saving, and low noise based on profound technical accumulation. It provides high-quality on-site liquid nitrogen preparation solutions for global customers, completely changing the many pain points of traditional liquid nitrogen relying on external purchase and transportation.
Core Advantage of High Efficiency: Rapid Gas Production to Stabilize Diverse Needs
The high efficiency of Jiangsu Minnuo’s liquid nitrogen machine stems from the precise control and process optimization of cryogenic air separation technology. Its skid-mounted liquid nitrogen solution adopts an integrated design, covering a full set of core components such as oil-free air compressors, PSA nitrogen generators, and refrigerators, realizing one-stop conversion from compressed air to liquid nitrogen. After the equipment is started, it only takes 10-15 minutes to produce qualified liquid nitrogen, completely getting rid of the problems of slow start-up and long waiting cycle of traditional liquid nitrogen preparation equipment. In terms of output, Jiangsu Minnuo’s liquid nitrogen machine covers a wide range from 10L/h to 100L/h (240L to 2400L per day), the nitrogen purity can stably reach the standard of ≥99%, and the dew point is as low as ≤-60℃, which can accurately match the differentiated needs of different scenarios such as medical freezing, food preservation, laboratory research, and industrial manufacturing.
Compared with the traditional mode of purchasing liquid nitrogen externally, Jiangsu Minnuo’s liquid nitrogen machine realizes on-site instant nitrogen production, which not only completely eliminates the loss and delay risks in the transportation of liquid nitrogen, but also ensures the continuity of the production process through stable gas production efficiency. Whether it is blood storage in hospitals, embryo freezing in IVF clinics, chip cooling in the electronics industry, or cold chain preservation in the food industry, Jiangsu Minnuo’s liquid nitrogen machine can protect production and operation with its efficient gas production capacity.
Energy Saving Benchmark: Low-Consumption Operation to Significantly Reduce Operating Costs
Energy saving is another core competitiveness of Jiangsu Minnuo’s liquid nitrogen machine, and it is also a key factor for many enterprises to choose its products. Relying on years of technical research and development experience, Jiangsu Minnuo has comprehensively optimized the core components of the liquid nitrogen machine, adopting well-known brand pneumatic valves and high-efficiency adsorbents to ensure higher adsorption efficiency and lower energy consumption during the operation of the equipment, while extending the service life of the components and reducing maintenance costs.
The intelligent control system equipped with the equipment has brought the energy-saving effect to the extreme, supporting three control modes: one-key start-stop, timing start-stop and liquid level start-stop. When the liquid level of the supporting liquid nitrogen tank reaches the set threshold, the system will automatically enter the standby state to avoid energy waste caused by invalid operation; at the same time, through the MCGS remote monitoring system, users can grasp the equipment operation status in real time, download historical operation records remotely, and timely find and solve possible energy consumption abnormalities. Data shows that the cost of producing liquid nitrogen using Jiangsu Minnuo’s liquid nitrogen machine is only one-third of the cost of traditional external purchase and transportation of liquid nitrogen. For enterprises that use liquid nitrogen stably for a long time, it can significantly reduce operating costs and improve the market competitiveness of enterprises. In addition, the equipment adopts water cooling method, which has higher cooling efficiency and further reduces the overall energy consumption, in line with the development trend of green production.
Low Noise Design: Quiet Operation to Optimize Working Environment Experience
In scenes with high requirements for working environment noise such as laboratories, hospitals, and beauty salons, the low noise advantage of Jiangsu Minnuo’s liquid nitrogen machine is particularly prominent. Through the structural optimization of core noise sources such as compressors and refrigerators, and matching with professional sound insulation and noise reduction components, the equipment effectively reduces noise pollution during operation. According to measured data, the noise value of Jiangsu Minnuo’s liquid nitrogen machine at a distance of 1 meter does not exceed 78dB at most, and the noise value of small-output models is as low as 72dB, which is far lower than the industry average, creating a quiet operating environment.
This low-noise design not only improves the work experience of operators, but also avoids the interference of noise on the surrounding environment. For example, in the diagnosis and treatment area of hospitals and the research area of laboratories, Jiangsu Minnuo’s liquid nitrogen machine can operate stably without affecting normal work; in food processing workshops, the quiet operation state will not cause additional noise pollution to the production environment, which fully reflects Jiangsu Minnuo’s in-depth consideration of users’ use experience.
Quality Assurance: Professional R&D, a Trustworthy Industry Benchmark
