Explosion-Proof Nitrogen Generator
Cryogenic nitrogen generator is an efficient nitrogen production system based on low-temperature distillation technology. By compressing and cooling the air to ultra-low temperature (below -196°C), the difference in boiling points between nitrogen and oxygen is achieved. This product covers standard industrial models and exploration-proof nitrogen generators, and is suitable for areas with strict requirements on nitrogen purity, flow rate and safety.
Features
- Ultra-high purity: Nitrogen purity can reach 99.999% or above
- Large-scale gas supply: Single-machine flow rate 500~50,000 Nm³/h, supports modular parallel connection
- Energy-saving design: Adopts high-efficiency heat exchanger and energy recovery system, with energy consumption as low as 0.3~0.5 kWh/Nm³
- Safety and reliable: Explosion-proof nitrogen generator complies with ATEX/IECEx certification, suitable for hazardous areas such as chemical industry and energy
