A new brochure compares operating features, savings, and maintenance costs of single-screw versus twin-screw compressors. It includes comparisons of 11 operating parameters, including part-load efficiency, thrust loads, compressor speed, bearing life, sound level, and warranty. Also featured is an energy comparison chart that demonstrates the typical annual energy savings of a single-screw compressor versus a twin-screw compressor. A detailed comparison of 15-year maintenance costs demonstrates a two-to-one savings advantage of single-screw compressors over twin-screw compressors, says the company.
