Centrifugal air compressor
Custom-Designed Oil-Free Centrifugal Compressor with API-Compliant Engineering & Smart Control.
- Ultra-Premium Efficiency: IE5 Permanent Magnet Motors.
- Two-Stage Technology: Lower compression ratio for longer life.
- IoT 4.0 Ready: Remote monitoring via smartphone app.
- Constant Pressure: Fluctuations within ±0.01MPa.
1.Customized Impeller & Aerodynamic Design
● Client-specific impeller optimization for peak efficiency (±0.5% variance)
● Wide operating range (flow ratio <1.5 per model, max 1500m³/min)
● 3D backward-curved blades improve efficiency by 1-8% vs. wedge-type designs
● Non-standard configurations available (11-35bar pressure range)
2.Vibration Control Beyond API Standards
● Rotor AF <2.5 (critical damping state per API 672)
● G0.4 dynamic balance (surpasses industry G1 standard)
● 17-4PH forged steel with 5-axis CNC machining (μm-level precision)
● Thrust ring design reduces axial bearing wear by 40%
3.Thermal Management System
● Oversized components:
✓ 2X air filters (<0.8kPa pressure drop)
✓ 1.5X oil coolers (inlet temp <40°C)
✓ API 614-compliant oil reservoir (5-min capacity)
● Dual cooling paths prevent heat accumulation
4.100% Oil-Free Guarantee
● Isolated sealing systems:
✓ Air seals vented to atmosphere
✓ Multi-stage labyrinth oil seals
✓ -2kPa gearbox vacuum prevents leaks
● Zero lubricant contact with compressed air
5.Smart Anti-Surge Control
● Dual protection logic:
✓ IGV minimum opening + temp compensation
✓ Current monitoring + proportional valves
● Three control modes:
✓ Constant pressure (0–100% flow adjustment)
✓ Auto dual-mode (load/unload cycling)
✓ Surge anticipation (handles >30kPa fluctuations)
6.Industry-Proven Applications
● Steelmaking: Stable blast furnace air supply
● Wastewater: 24/7 operation in municipal plants
● Bio-fermentation: Heat recovery compatibility
● Chemical processing: MODBUS/DCS integration
7.Why It Stands Out
✔ 25-year gear life (AGMA 13 precision + 17CrNiMo6 steel)
✔ 60% lower vibration than API thresholds
✔ 30% wider operating range vs. competitors
✔ Remote O&M via 10.2″ HMI + mobile APP
| Model | Power (kW) | Capacity (m³/min) | Pressure (bar) | Weight (kg) |
|---|---|---|---|---|
| SZ-75AII | 75 | 15.2 | 8 | 1850 |
| SZ-110AII | 110 | 22.5 | 8 | 2400 |
| SZ-160AII | 160 | 32.8 | 8 | 3100 |
✓ Rapid return on investment
The electricity savings can typically cover the equipment purchase cost within 12-24 months.
✓ Intelligent cloud management
Through the Internet of Things (IoT) system, you can check the machine’s power consumption, stress, and maintenance reminders anytime, anywhere.
Internal Structure & Components
