Ingersoll Rand HB heated blower desiccant dryers are equipped with dedicated durable centrifugal blowers to provide purge air for regeneration, eliminating the need to divert dry compressed air from the air system. Instead, the blower directs ambient air through an external heater and then through the off-line tower to regenerate the desiccant. This means more compressed air is available for critical downstream applications. Available in sizes from 4.2 nm³/min. (150 scfm) to 226.5 nm³/min. (8,000 scfm), Ingersoll Rand HB dryers deliver -40°C (-40°F) pressure dew point air.
