Description
The Clean Resources EHD Series External Heater Regenerative Desiccant Dryer uses fully pneumatic stainless steel actuator valves rather than dated shuttle valves. This allows for independence of flow and pressure. The EHD Series is certified with ASME, CRN, UL, CUL certification.
The EHD utilizes an automatic system using a centrifugal blower and a high-efficiency heater that pulls in ambient air and passes it through the heater. This eliminates the need to use valuable compressed dry air for desiccant regeneration. Instead, more compressed air goes to plant operations. The hot air stream from the blower flows opposite to the drying flow direction. Hot air above 400°F regenerates the moisture-laden desiccant bed and strips it completely of moisture. The advanced control system monitors the dewpoint and adjusts the heating/regeneration accordingly, providing significant energy savings. The heater circuit is completely insulated, ensuring maximum heating efficiency.
