700bar 충전소를 위한 무급유 수소 압축기의 차별화 요소

Achieving 700-bar hydrogen compression is essential for modern fuel cell vehicles—but only 오일 프리 수소 압축기 can deliver the necessary purity, reliability, and safety. Let’s explore what sets them apart and why they’re the backbone of high-pressure hydrogen refueling systems.


1. Guaranteed Purity – No Oil Contamination

Hydrogen fuel cells are extremely sensitive to contaminants. Oil residue as low as parts per million can damage stacks or destroy downstream systems. Oil-free compressors—whether diaphragm, dry-piston, or ionic-liquid—eliminate lubrication and prevent any oil carryover, ensuring hydrogen remains ultra-pure .


2. Engineered for Extreme Pressure

Reaching 700 bar requires compressors built to handle extreme pressures. Oil-free reciprocating piston 그리고 다이어프램 컴프레서 offer multi-stage compression capable of delivering this level safely and efficiently. Diaphragm variants, for example, can reach 700 bar with fewer stages and higher compression ratios  .


3. Advanced Seal Design to Prevent Leaks

At 700 bar, even microscopic leaks are unacceptable. Oil-free systems employ dry gas seals, diaphragm barriers, or ionic-liquid pistons to maintain integrity and withstand hydrogen’s small molecular size  .


4. Safety Under High Sonic Speed & Embrittlement Conditions

Hydrogen’s low molecular weight results in higher sonic speeds and pulsation effects—more so at 700 bar  . Additionally, materials are engineered to resist 수소 취성, ensuring long-term integrity and safe operation.


5. Optimized for Fueling Station Demand

700-bar fueling requires filling vehicles rapidly under SAE J2601 specifications. Oil-free compressors provide the necessary consistency and flow for fast, safe refueling cycles, with cascade buffer systems upstream of dispensers .


⚙️ Real-World Technologies at a Glance

  • 무급유 피스톤 컴프레서: Proven multi-stage systems, scalable to 700 bar (>350 bar inlet); ideal for large stations .

  • Metal Diaphragm Compressors: Capable of single or two-stage compression to 700 bar, with leak-free diaphragms; widely used in H2 fueling .

  • Ionic‑Liquid Compressors: Compact, few moving parts, built for oil-free compression with reduced maintenance—designed for high-volume stations (≤700 bar).


✅ Key Benefits of Oil-Free Systems

혜택 Why It Matters
Ultra-High Purity Protects fuel cell stacks and infrastructure
High Pressure Capability Meets SAE J2601 700 bar refueling standards
Leak-Proof Integrity High-pressure safety and compliance
Lower Maintenance No filter/oil changes, reduced service intervals
Durability & Safety Hardened materials, embrittlement resistance

If your hydrogen station must support 700-bar fueling, 오일 프리 수소 압축기 are not optional—they’re required. With advanced sealing, pressure capability, and contamination-free design, they deliver safe, reliable, and efficient high-pressure refueling.
