The Drying unit has 2-vessels filled with Activated Alumina or Molecular sieves desiccant. One vessel remains in drying cycle for 4 hours, while other vessel simultaneously regenerates at atmospheric pressure. Around 3% flow of dryer capacity is used as purge for regeneration. Electrical heaters are provided in a central finned Stainless steel pipe in both drying vessels. Heating cycle is for 2 hours and in this time hot purge air increases desiccant temperature to around 100 degree C. At this temperature regeneration is complete (due to dry air purge). Dew point achieved is around (-) 40 degree C. If still lower Dew point is required, air purging rate is slightly increased to 5% for (-) 60 degree C and to 7.5% for (-) 80 degree C Dew point.
