Rainbowe Machinery launches new permanent magnet variable frequency screw compressors

Shaoxing Rainbowe Machinery Co., Ltd., a Chinese manufacturer, has initiated serial production of new screw compressors. These new units integrate permanent magnet synchronous motor technology with variable frequency drive (VFD) systems, aiming to provide energy efficiency for industrial applications.

The compressors are offered in three power configurations: 7.5 kW, 11 kW, and 15 kW. Depending on the model, the displacement ranges from 1.1 to 2.8 cubic meters per minute at a rated exhaust pressure of 0.8 MPa. The machines are designed to operate within an ambient temperature range of -5 to 45 degrees Celsius, with a reported noise level of 66 decibels.

Rainbowe Machinery also produces other industrial machinery, including yarn twisting machines and sock knitting machines. The company's announcement did not specify pricing or international availability for the new compressor models.
