This question is about heated and heatless instrument air dehydration packages.
While heated dehydration systems rely on blower/heater combination for regeneration, heatless systems require a dry instrument air stream for regeneration (up to 15%) which leads to a larger compressor to ensure a steady supply of IA.
Which of these heated/heatless systems is better and why? Are there significant lifecycle cost and availability/reliability issues to differentiate?
