Therefore a higher turndown ratio implies slower speeds are possible without causing damage. i.e. the speed can be "turned-down" more.

Our motors have a range of 50-105% RPM. At 50%, the centrifugal compressors are spinning but at normal operating pressures they're performing very little compressing.

Example; a gas burner will operate over a range of 250,000 BTU/Hr. to 10,000,000 BTU/Hr. The turn down ratio is 10,000,000/250,000 = 40 or 40:1
Does this explanation fit your context?
