110Kw/150Hp Two-Stage Rotary Screw Air Compressor Permanent Magnetic Variable Frequency 380V Air Cooled
Core Advantages
- The permanent magnet motor maintains high efficiency at low speeds, delivering obvious energy-saving advantages under low air volume conditions.
- Frequency range covers 0%-100% (vs. 60%-100% for common variable frequency compressors).
- Saves 22%-40% energy compared with fixed-speed compressors.
- Saves 5%-15% energy compared with common inverter compressors.
- Larger system volume fluctuations result in more obvious energy-saving effects.
- Unloading energy saving (inverter):
Traditional stationary air compressors have idling periods during gas consumption fluctuations, requiring 45% electricity even when idling. The permanent magnet VFD air compressor eliminates unloading and energy waste through inverter control; larger units achieve greater savings.
- Pressure control bandwidth energy saving:
Fixed-speed compressors require a minimum 1Bar control pressure band to avoid impact on units and power grids, leading to wider pressure ranges when multiple machines operate together. The OSG permanent magnet VFD series uses inverter control with unlimited stops, operating at a single pressure point. Every 0.14Bar reduction in pressure bandwidth saves 1% energy.
- Energy-saving startup (inverter):
Air compressor starting current is 3-6 times the rated current, and frequent starts waste large amounts of energy. The variable frequency type uses soft start without frequent start-stop, with maximum current not exceeding rated working current, eliminating energy waste and reducing impact on power grid equipment.
Professional serviceAfter-sales service is always a key concern, and timely support is essential. We have professional after-sales engineers and complete spare parts inventory. Our service branches provide timely, professional service and technical training to every customer.
Adequate resource supplyUsing genuine OSG spare parts and consumables is the basic guarantee for long-term compressor operation. We maintain normal and efficient operations with sufficient spare parts and consumables reserves to meet customer needs at any time.
Product quality guaranteeHigh-quality products are the core foundation of business operations. Every product undergoes strict performance and operation tests from raw material procurement and outsourced parts processing to final production, ensuring high-quality machines.
