Overview
The O2 reciprocating compressor is a high-efficiency, oil-free compression system designed specifically for the safe and reliable compression of oxygen gas. Engineered to meet the stringent demands of medical, industrial, and high-purity applications, this compressor ensures contamination-free operation, excellent gas purity, and long service life.
Features
- Oil-Free Design
Completely oil-free compression chambers prevent hydrocarbon contamination, ensuring the oxygen remains clean and dry — ideal for applications with high purity requirements such as medical oxygen supply, gas filling stations, and metallurgy.
- Multi-Stage Compression
Most units adopt two- to four-stage compression structures to effectively reduce temperature rise and optimize energy efficiency while achieving required discharge pressures (typically up to 5–30 bar or customized higher pressures).
- Low Discharge Temperature
Efficient inter-stage cooling systems (water or air-cooled) minimize heat buildup, extending component lifespan and enhancing system reliability.
- High Gas Purity Handling
Compatible with 99.5% and higher purity oxygen; tailored internal treatments and surface coatings ensure safe handling of oxidizing gases.
- Explosion-Proof and Oxygen-Compatible Materials
Constructed with non-sparking materials such as stainless steel, copper alloy, or anodized aluminum, minimizing fire hazards in oxygen-rich environments.
Applications
- Medical & Healthcare
Used in oxygen cylinder filling systems, PSA oxygen generator booster systems, and centralized oxygen supply stations.
- Metallurgical Processing
Supplies pressurized oxygen for steel refining, non-ferrous metal smelting, and glass manufacturing processes.
- Wastewater Treatment
Oxygen aeration and ozone generation processes require clean and dry compressed oxygen.
- Environmental Protection
Oxygen compression in bio-reactors and ozone generation systems.
- Gas Filling Plants
Used for bottling of medical or industrial oxygen in high-pressure cylinders.
