Heatless Dryer simplest type of air dryer with Activated Alumina/Molecular Sieves drying agent. Heatless Dryer is virtually maintenance free, fully automatic, and requires no attention for year. Heatless Dryer does not require any heating for re-generation and therefore are very simple in design and maintenance free.
Operating Principal
In Heatless Dryers, two vessel filled with desiccant are provided which cycle automatically, producing dry air continuously. In these units, wet air enters the bottom of one Vessel and passes upwards through the desiccant bed where the moisture is adsorbed. The dry air comes out from the top. A small portion of dry air is passed downwards through the desiccant bed in second vessel, which is under re-generation. Moisture laden purge air is then vented out to atmosphere. The purge loss is around 7.5% of the total airflow. At preset interval, the vessel changeover automatically, and Dry air is available continuously, without any surge.

Low Operating Cost
Due to its inherent simple design, investment in this type of dryer is the cheapest and the payback on this investment is very quickly. Low Temperature operation reduces corrosion in tower and desiccant lasts longer. Power requirement is 60 watt only for Solenoids Valves Operation
Capacity

• Air Capacity : 5 to 10000 NM³/Hr.
• Dew Point : Up to (-) 60^oC
• Operating Pressure : 5 to 35 Kg/cm²g
