As the leading ship supplier in Ross Dependency, Propeller Performance Optimization, we specialize in delivering high-quality High Purity Nitrogen Gas with unmatched speed and reliability. Trusted by shipowners and masters worldwide, our team ensures your vessel gets everything it needs — on time, every time.
High Purity Nitrogen Gas is a ultra-clean, inert gas used in sensitive applications like electronics manufacturing and laboratories. Specialty Gases are customized gas mixtures or pure gases tailored for specific industrial, medical, or scientific uses. Both are critical for precision processes requiring controlled atmospheres or exact gas compositions.
High Purity Nitrogen Gas:
- Purity: 99.999% (5.0 Grade) or higher
- Molecular Weight: 28.0134 g/mol
- Density: 1.165 kg/m³ at 20°C
- Viscosity: 17.5 μPa·s at 20°C
- Buoyancy: Lighter than air (non-buoyant in air)
- Material: Inert diatomic gas (N₂)
- Common Sizes: 10L, 20L, 40L, 50L cylinders; bulk liquid (ISO containers)

Specialty Gases (General Properties):
- Purity: Custom grades (99.9% to 99.9999%)
- Molecular Weight: Varies by gas (e.g., Ar, He, CO₂)
- Density: Gas-dependent (e.g., He lighter, CO₂ heavier than air)
- Viscosity: Gas-dependent (e.g., He ~19.9 μPa·s, CO₂ ~14.8 μPa·s at 20°C)
- Buoyancy: Varies (He buoyant, CO₂ sinks)
- Material: Pure or mixed gases (e.g., calibration, laser, semiconductor grades)
- Common Sizes: 2L to 50L cylinders, mini-bulk, tonnage supply
- Pressure: 50-300 bar (varies by application)
