A centrifugal blower and high efficiency heater elliminates the use of valuable compressed air to be used for desiccant regeneration. The completely automatic drying system uses blower to pull ambient Air and pass it through the heater. This hot Air stream flows opposite to drying flow direction. Hot Air above 200 oF regenerates the moisture inside desiccant bed and strips it completely of all moisture. The advanced control system monitors the dew point and adjusts the heating / regeneration accordingly thereby providing valuable energy savings. The heater circuit is completely insulated ensuring maximum heating efficiency.
