Closed loop low dew point heated blower desiccant air dryer sucks ambient air, after passing through high
precision filtration and heating equipment, to heat and regenerate the desiccant. After finishing heating and
regeneration, ambient air continue to cool high temperature desiccant and cool after flowing through cooler,
which form closed loop cooling, cooling end means regeneration completion. This process doesn't lose any
compresssed dry air.
