Hello,

We are reverse engineering a dehumidifer like this one:

The Sunpentown SD-652 TEC dehumidifier

It uses a Peltier-cooler to dehumidify the air. We have dimantled it (basically removing the chassis/case) and have mounted just outside, but with access, to a chamber of about 3 cu ft. It does not seem to dehumidify the air much at all. The ambient RH% is about 55-60 percent, and we cannot seem to dehumidify this air in the 40-50% range. We would like to custom make a TEC (not compressor based) humidifier. Is there a good TEC module or modules to use to achieve this task?

Thanks
Mike
