Commercial Desiccant Dehumidifier

Energy  Efficient  Recirculating  Dehumidifier

Advanced Humidity Control

The  Commercial Dehumidifier is an ultra-efficient dehumidification system that combines the benefits of desiccant dehumidification and mechanical  cooling. The system design permits the capture of condenser heat (normally rejected as waste) to power desiccant dehumidification. The Dehumidifier units provide low dew point air at space-neutral dry-bulb temperature. Multiple standard Dehumidifier unit sizes are available from 300 to 10,000 cfm and unit design may be further customized to match required dehumidification capacity. Operation is fully independent of space temperature control so target humidity levels are maintained regardless of space cooling or heating demand.

BENEFITS

Commercial Desiccant Dehumidifier

• ·         Unmatched dehumidification efficiency
• ·         Temperature-neutral operation provides effective refrigeration capacity
• ·         Capable of lower dew points than conventional technology
• ·         Prevents mold, mildew and dust mite growth
• ·         Independent humidity control maintains comfort at higher dry-bulb set point
• ·         Preserves building materials by lowering equilibrium moisture content and eliminating condensation or other collected water

HOW IT WORKS

The core of the dehumidifier is a refrigeration loop coupled with a desiccant dehumidification wheel. In dehumidification mode, return air passes first through the evaporator coil where it is cooled and typically experiences some dehumidification and then through the desiccant wheel where the air is dried to a low dew point. In the isolated regeneration section of the unit, outdoor air is used to capture rejected condenser heat and regenerate (dry) the desiccant wheel. The wet air exiting the regeneration half of the desiccant wheel is exhausted.

Units are typically designed so that cooling through the evaporator coil matches re-heat through the desiccant wheel to provide for temperature-neutral operation and to facilitate parallel operation with equipment used for sensible temperature control. Optional post heating or cooling is used to further control the supply air conditions if required. The use of the desiccant wheel following the  section ensures the lowest possible supply air dew points with significantly less energy consumption than the typical process of over-cooling followed by reheat.
