Liquid Nitrogen Production
The liquid nitrogen production system uses advanced cryogenic air separation technology to provide ultra-high purity liquid nitrogen (LIN) for industries such as food freezing, pharmaceuticals, electronics and metal processing. With precise temperature control and energy-saving design, our liquid nitrogen production solutions ensure stable and economical operation and meet the needs of different industries.
Core product advantages
- High efficiency and energy saving – Optimized distillation tower and heat exchanger design to significantly reduce energy consumption.
- Ultra-high purity – Nitrogen purity is up to 99.999%, suitable for high sensitivity applications.
- Flexible expansion – Modular design supports capacity requirements from 5 liters/hour to 50,000 liters/hour.
- Intelligent control – The automated system monitors flow, pressure and temperature in real time to ensure stable operation.
Purity and flow range
- Purity grade: industrial grade (99.5%~99.9%), food grade (99.9%~99.999%)
- Flow range: 5~50,000 LPH (can be customized according to requirements)
- Dew point temperature: ≤-70°C to ensure no moisture residue
Temperature and pressure parameters
- Storage temperature: -196°C (standard liquid nitrogen boiling point)
- Working pressure: 0.8~1.2 MPa (adjustable, adaptable to different application scenarios)
- Evaporation loss rate: <0.1%/day (vacuum insulation storage tank technology)
Energy consumption and environmental protection indicators
- Specific energy consumption: ≤0.35 kWh/Nm³ (industry-leading level)
- Cooling capacity recovery rate: ≥85% (efficient waste heat utilization)
- Carbon emissions: 30% lower than traditional processes
International certification standards
- ISO 8573 (Compressed Air Purity Standard)
- ASME BPVC (Pressure Vessel Safety Certification)
- FDA/GMP (food and drug grade compliance certification)
- CE/PED (EU Pressure Equipment Directive)
Industry application cases
- Food processing: quick-frozen seafood and ice cream production line (-196°C flash freezing)
- Medical cold chain: ultra-low temperature storage of biological samples and vaccines
- Electronics Manufacturing: Semiconductor Packaging Inert Gas Protection
- Metal treatment: aluminum alloy quenching, superconducting material cooling
