Tandem Two-Stage PM VSD Air Compressor
The Sazhen series of two-stage air compressors are specifically developed for industrial energy conservation. They utilize an IE5 ultra-high-efficiency oil-cooled permanent magnet motor, maintaining extremely high efficiency even under low loads, saving an average of over 30% more electricity than single-stage compressors.
- 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.
Advanced Two-Stage Compression Technology
Two-stage compression divides the pressure process, which would normally be achieved in one step, into two stages. An intermediate cooler lowers the temperature of the air entering the second stage of compression. This not only improves compression efficiency but also significantly reduces bearing load, extending the lifespan of the compressor to over 15 years.
