I. Core Technology & Environmental Adaptability
• Deep Adaptation to Low-Pressure Environments
Technology: Adopts low-pressure oil-free adsorption technology with an adsorption pressure as low as 0.7 bar.
Advantage: Perfectly matches the low-pressure working conditions at high altitudes, with controllable oxygen concentration attenuation. It can stably output ≥87% medical oxygen concentration (referencing ISO 80601-2-69 standard) even at altitudes of 4000-5000 meters, and the molecular sieve is less prone to pulverization with a longer service life.
Comparison: Superior to traditional high-pressure models, solving the pain point of insufficient oxygen concentration in high-altitude areas.
• Robust Protection for Extreme Cold Environments
Technology: Equipped with low-temperature reinforced design, with core components adapted to operate in a wide temperature range of -20℃ to 40℃.
Advantage: Key circuits and sealing materials are treated for anti-freezing, capable of handling extreme conditions such as large day-night temperature differences and icing blockages. The integrated shelter solution comes with insulation, fireproofing, and noise reduction functions, enabling stable oxygen supply immediately upon power connection.
Value: Ensures immediate startup and operation without delays in extreme cold environments, guaranteeing continuous oxygen supply.
II. Stability & Operation & Maintenance Advantages
• Oil-Free Oxygen Generation Ensures Long-Term Reliability
Technology: Full-process oil-free air compressor design, with oil-free compressed air.
Advantage: The molecular sieve is not contaminated, eliminating the need for multi-stage oil filtration, reducing maintenance costs by approximately 1/3, and making annual operating costs more controllable.
Validation: 12 units of 40m³ equipment have been operating safely and continuously for over 4 years in Yushu at an altitude of 4200 meters.
• Intelligent Operation & Maintenance Reduces Management Burden
Technology: Equipped with a remote operation and maintenance system.
Advantage: Supports multi-terminal monitoring via mobile phones/computers, with real-time alarms, data traceability, and remote parameter adjustment, enabling unmanned or minimally manned operation in extreme cold and high-altitude areas.
Value: Significantly reduces operation and maintenance difficulty and labor costs in extreme environments.
III. Economic Efficiency & Scenario Adaptability
• Significant Energy-Saving Advantage
Technology: Low-pressure adsorption + oil-free design.
Advantage: Saves more than 40% energy compared to traditional models, resulting in lower electricity and maintenance costs during long-term operation in extreme cold regions.
• Full-Scenario Solutions
Product Series: Offers Yu Series single-tower equipment (simple structure, easy installation) and He Series shelters (no need for building construction, mobile deployment).
Adaptable Scenarios: Perfectly suitable for scenarios without fixed stations such as sentry posts, camps, and airports, meeting diverse needs.
