Nitrogen (N₂) is abundant (78% of air), colorless, odorless, and inert.
Key Features:
Applications:
Model: 2VF-4.4/5-400
Flow Rate: 1,500 Nm³/h (Standard conditions: 0°C, 1 atm)
Inlet Pressure: 5 bar (Customizable range: 3–8 bar)
Discharge Pressure: 400 bar (Max. 450 bar for ultra-high-pressure needs)
Compression Stages: 4-stage optimized design
Drive Options: Variable-speed electric motor / Diesel engine
Cooling System: Air + Interstage water cooling (ensures thermal stability)
Control System: Intelligent PLC + HMI (real-time monitoring of pressure, temperature, vibration)
1. Sky-High Energy Costs?
Problem: Traditional compressors waste energy with inefficient compression cycles.
Our Solution: Advanced 4-stage compression with isentropic efficiency up to 85%, reducing energy consumption by 20%.
2. Frequent Downtime from Breakdowns?
Problem: Unstable performance and leaks under extreme pressure.
Our Solution: Forged steel cylinders + alloy-coated pistons ensure zero leakage at 400 bar, backed by vibration sensors and automatic shutdown for overload protection.
3. Costly Maintenance Cycles?
Problem: Complex repairs and frequent part replacements.
Our Solution: Modular design allows 50% faster maintenance, while oil-free technology and self-lubricating bearings extend service intervals to 8,000 hours.
4. Struggling with Variable Gas Demands?
Problem: Rigid compressors can’t adapt to fluctuating workflows.
Our Solution: Variable-speed drive adjusts output in real time, and a 3–8 bar inlet range accommodates unstable gas sources.
