Product Description

China manufactured ULPPRO Two stage Compression Permanent Magnet Variable Frequency Screw Air Compressor, adopts industry-leading dual-stage mainframe, with the unique intermediate cooling liquid spray curtain design reduces the temperature of the air, and the compression process approaches the most energy-efficient isothermal compression. In principle, the two-stage compression is 10%-15% more energy-efficient than the single-stage compression. Two-stage compression has a smaller compression ratio, less leakage, lower bearing load, and greatly increased bearing life. The design concept of "large rotor, large bearing, low speed" is adopted, which reduces noise and vibration, and increases the lifespan and stability of the main unit. The rotor tooth surface is processed by a grinding machine, creating a high-precision rotor, which is the first guarantee for the efficiency and stability of the main unit. A new asymmetric rotor tooth shape is adopted, and it is fully measured by a high-precision three-coordinate measuring machine, with excellent quality.

Two-stage Compression Energy-saving Case

Single-stage compression air compressor with 250KW capacity

Two-stage compression air compressor with 250KW capacity

The electricity cost for each hour of full-load operation is approximately RMB200

The annual electricity cost for 8000 hours of operation is approximately 1.6 million RMB

Using a two-stage compression air compressor

Can reduce power consumption by more than 10%

Using two-stage compression will save 160,000 RMB annually
