Reciprocating units need time to stop and cool off, or the internals will become damaged. When damage occurs, the compressor can experience valve failures, causing the compressors to run constantly. ... With modulation, a control valve chokes off the inlet of the compressor to control the flow and pressure.


I hope this is helpful? PLEASE "ACCEPT" and mark it "HELPFUL" to complement my little effort. Hope to bring you more detailed answers
