Solar manufactures 10 families of centrifugal gas compressors - the most extensive line in the industry. Solar®Compressors are compliant with API 617 to ensure rugged and reliable operation. Depending on the model, the compressors have from 1-12 stages to handle a variety of inlet flows and pressure ratios. Compressor sets with a single Solar compressor can produce ratios of over 5:1 while multiple, tandem-mounted compressors can produce pressure ratios approaching 40:1. The modular component design simplifies restaging Solar's centrifugal compressors to meet changing field conditions.
