The 90-132kW single-stage permanent magnet variable-speed screw air compressor is a medium-to-large industrial air compressor with a rated power range of 90 to 132 kW. Its core technology utilizes a single pair of screw rotors for primary compression, combined with a permanent magnet synchronous motor and variable frequency speed regulation. This allows it to precisely match the user's air demand by varying motor speed, achieving extremely high operating efficiency, stable air pressure output, and intelligent control. It is a typical example of a modern energy-saving air compressor.
Advantages of permanent magnet variable frequency air compressor.
1. Extreme Energy Savings and High Return on Investment
90-132kW motors consume significant power, consuming nearly 100 kilowatts of electricity per hour of continuous operation. The high efficiency of permanent magnet motors, combined with the inverter's on-demand air supply control, avoids significant idle power waste. Under conditions with large fluctuations in air demand, energy savings can typically reach 25%-40%.
2. Excellent Air Pressure Stability and Air Supply Quality
Variable frequency control enables precise constant pressure control to within ±0.1 bar. For precision pneumatic equipment, automated robots, CNC machining centers, and other equipment in large factories, stable air pressure is crucial for ensuring production accuracy, consistency, and yield.
3. Powerful Grid Protection and Soft-Start Advantages
Starting such a high-power motor directly would significantly impact the factory power grid, potentially causing a sudden voltage drop and impacting other precision equipment.
4. Permanent magnet variable frequency drives utilize soft start, resulting in a starting current less than twice the full-load current. This allows for smooth startup and completely eliminates impact on the power grid, making them "friendly" to modern factory power systems.
5. Multi-machine Control and Intelligent Management
Air compressors in this power range are typically the core of factory air compression stations and feature advanced intelligent control systems. This allows for easy coordinated control of multiple compressors, automatically determining which compressor to start and at what frequency based on total gas demand, ensuring the entire station operates within the highest energy efficiency range and enabling "unmanned" intelligent management.
6. High Reliability and Longer Service Life
Reduced Start/Stop Frequency: Variable frequency operation eliminates frequent loading/unloading or start/stop cycles for power frequency drives, significantly reducing mechanical and electrical shock to the main unit, motor, and electrical system.
7. Soft Operation
Smooth starts and stops, as well as speed changes, extend the service life of bearings, transmission systems, and the entire main unit, reducing failure rates and maintenance costs.
