In key areas such as medical, industrial and environmental protection, oxygen systems play a vital role – not only in relation to the life support of ICU patients and the combustion efficiency of high-temperature furnaces, but also in influencing the continuous operation of green production processes such as water treatment and waste gas treatment. A stable and efficient oxygen supply system is the core foundation for production and service safety.
However, in the face of a wide variety of oxygen equipment on the market with huge price differences, how to scientifically assess the reliability and applicability of the brand has become a real problem that procurement decision makers urgently need to solve. The brand’s technology accumulation, system integration capability, after-sales service response speed, etc., directly determines the performance of the equipment in the actual application and the long-term cost of use.
In this article, we will take MINNUO oxygen equipment as a research sample, and analyze its ability to land in the three major fields of medical+industrial+special environment from the perspectives of product series, performance, certification, application scenarios, user feedback, etc., and analyze it with the mainstream brands in the market, so that we can help you to establish a clear and practical logical framework of brand evaluation and make a more scientific judgment of model selection.
1.Product Range Overview
MINNUO has a complete and clear structure of oxygen equipment product system, which can be divided into three series according to the application, covering the diversified needs from medical rescue to industrial application, from fixed site to mobile scene:
Medical PSA Oxygen Generation System
Mainly serves in hospital ICU, operating room, negative pressure ward, community site, etc. It adopts medical molecular sieve adsorbent technology, and stably outputs 93% ±3% of the oxygen concentration. Adopting medical molecular sieve adsorption technology, it has a stable output of 93% ±3% oxygen concentration and meets the medical specifications such as YY/T 0298 and ISO13485. The system supports dual-tower switching, centralized monitoring, oxygen concentration alarm and UPS emergency switching to ensure uninterrupted oxygen supply.
Industrial VPSA / PSA system
Widely use in metallurgy (iron and steel refining), glass combustion, ozone system, water treatment, etc. It supports medium and large flow ranging from 50~3000Nm³/h. VPSA system adopts low-pressure adsorption+vacuum desorption structure, which has low energy consumption and is suitable for long-term high-load operation; while the PSA structure is more compact and is suitable for small and medium-sized continuous oxygen supply occasions. The system supports centralized oxygen supply, remote control and tail gas treatment.
Mobile Oxygen System
includes vehicle-mounted all-in-one machine, box integrated equipment, etc. It is suitable for temporary or plateau application scenarios, such as rescue fleet, field medical point, plateau post, etc. The system is equipped with compressor, buffer tank and oxygen tank. The equipment comes with compressor, buffer tank and touch screen control, and some models support vehicle power supply/generator interface and solar energy replenishment to meet the deployment needs of remote and power failure places.
Comprehensive coverage of model parameters and strong adaptability:
Oxygen purity: 93%, 95%, 99.5%
Flow rate range: 10 L/min ~ 3000 Nm³/h
Power range: 1.5kW~100kW+
Working pressure: 0.3~200bar
Support for non-standard customization capabilities:
MINNUO has rich engineering experience, and can be customized to meet the needs of customers’ environments, including:
Plateau-adapted design (customized air compressor unit)
Voltage/frequency adjustable module (supporting 220V/380V/50Hz/60Hz)
Special material anti-corrosion structure (adapted to high humidity/salt spray working conditions)
Intelligent remote control interface (supporting PLC/485/Modbus)
2. Performance Evaluation
The performance evaluation of oxygen equipment should not be confined to the theoretical parameters, but should also take into account the stability of actual operation, energy consumption, maintenance frequency and the degree of intelligence to build a scientific and comprehensive evaluation system. The following is an analysis of the performance of the MINNUO oxygen system in the core performance dimensions:
Oxygen purity stability
Whether the equipment can continue to output oxygen concentration that meets the standard after a long period of operation is one of the basic indexes that medical and industrial users are most concerned about.
MINNUO system adopts ±0.5% accuracy on-line concentration monitoring, which can maintain the concentration in the range of 93%~95% (PSA) or 95%~99.5% (VPSA) even after long-term operation.
The system is equipped with the function of abnormal oxygen concentration alarm + automatic switching of backup gas source, which effectively reduces the risk of fluctuations in purity for end-use.
Comparative Analysis of Energy Consumption
Compared with traditional PSA or similar equipment in the market, MINNUO’s highly recommended VPSA series shows significant energy consumption advantages in medium and large flow rate scenarios:
Adsorption tower with low-pressure operation + vacuum resolution design, the overall energy consumption per unit of gas production is less than 0.45kWh/Nm³ (some models).
Variable frequency blower and energy-saving vacuum pump can be configured to save energy and adjust speed according to real-time oxygen consumption, which is suitable for electricity price-sensitive areas (e.g. Middle East/Southeast Asia).
Operation Stability and Maintenance Frequency
System reliability directly affects the economy and operation risk of long-term use:
Compressor/molecular sieve module design life ≥ 3 years, molecular sieve does not need to be replaced under normal use conditions;
Long maintenance cycle: compressor/air-cooled module only needs 4000~6000 hours of maintenance;
Fewer wearing parts, easy maintenance, especially suitable for remote areas or lack of technicians on-site use.
Customer feedback shows:
In the Middle East, Africa and other high-temperature and high-humidity areas running more than 8000 hours/year, the system is highly stable, basically no fault shutdown records.
Intelligent Control Capability
Whether the equipment supports remote management and data linkage is an important concern for modern users. MINNUO has mature solutions in this regard:
Control system: integrated PLC + touch screen HMI, supporting multi-language interfaces, permission grading;
Data protocol: compatible with SCADA, Modbus, 485, 4-20mA, TCP/IP, can be accessed to the hospital HIS system or factory MES; Remote Management Data protocol: compatible with SCADA, Modbus, 485, 4-20mA, TCP/IP, and can be connected to hospital HIS system or factory MES;
Remote management function: remote parameter configuration, alarm linkage, and cloud view of operation data, which is convenient for centralized operation and maintenance and remote debugging support in different regions.
3.Certifications and Compliance
Oxygen system as a key equipment in medical and industrial fields, its compliance not only relates to whether the equipment itself can be put into use safely, but also is an important foundation for users to smoothly pass customs acceptance and docking international standards.MINNUO has solid system and certification achievements in this dimension, which can provide full endorsement for all kinds of project landing.
