Hospital Medical Oxygen Plant

As a centralized oxygen supply core equipment for medical institutions, the Hospital Medical Oxygen Plant relies on Pressure Swing Adsorption (PSA) technology to separate and purify air, stably delivering high-purity oxygen that meets medical standards. It provides 24/7 life-support oxygen for critical scenarios like ICUs, operating rooms, and emergency departments. Its core value lies in achieving on-site independent oxygen production (reducing reliance on external supply chains of cylinders or liquid oxygen), ensuring supply safety, and cutting long-term operating costs—making it an indispensable infrastructure for modern hospitals.

Description

Technical Parameters

Core Working Principle

Using ambient air as raw material, the system completes oxygen production via PSA technology through four key steps:

① Air pretreatment: Oil-free air compressors compress air; precision filters and freeze dryers remove impurities and moisture.

② Molecular sieve adsorption: Clean air enters towers filled with zeolite molecular sieves, which adsorb nitrogen and CO₂, allowing high-purity oxygen to pass through.

③ Pressure regulation & regeneration: Dual/multi-tower alternate operation (one tower adsorbs while the other regenerates via pressure relief) ensures continuous oxygen output.

④ Oxygen purification & storage: Qualified oxygen (monitored by online analyzers) is stored in buffer tanks and delivered to hospital oxygen supply pipelines.

FAQ

Q1: What qualifications must the Hospital Medical Oxygen Plant and its supplier have to ensure compliance?

A1: The plant needs a Class II Medical Device Registration Certificate (China) and meets YY/T 0298, GB 8982-2023. Suppliers: Manufacturers need production licenses; sellers need Class II operation filings. Exports require CE/FDA/ISO 13485. Verify via national medical device databases.

Q2: How does the total cost of a PSA-based medical oxygen plant compare with liquid oxygen tanks? Which is more cost-effective long-term?

A2: PSA plants have higher initial costs but save 60%+ long-term vs. liquid oxygen (avoids transport/storage fees). Costs only include electricity (≤0.38kWh/Nm³) and maintenance, breaking even in 3-5 years. Suitable for ≥50-bed hospitals; small clinics may prefer liquid oxygen.

Q3: Can the plant adapt to high-altitude areas (e.g., 3500m above sea level)? What special configurations are needed?

A3: Yes, with high-altitude customization: upgrade air compressors, optimize sieve quantity/pressure (0.6-0.8MPa), and strengthen drying systems. Qualified models need test reports proving "purity ≥90% at 3500m."

Q4: What are the pros and cons of the BOO operation mode for hospital oxygen plants? Is it suitable for general hospitals?

A4: BOO pros: No upfront hospital investment, freeing funds for medical equipment. Cons: Weakened hospital control (risk of supplier cost-cutting). Suitable for medium/small hospitals; large tertiary hospitals prefer self-owned models.

Q5: How to confirm that the plant's labeled oxygen flow and purity are true and avoid false marking?

A5: Avoid false marking by: ① Checking CMA/CNAS-certified third-party test reports; ② On-site 24h full-load testing with calibrated analyzers; ③ Avoiding quotes 20% below market average.
