Anything under 15°C is low temperature for a dehumidifier and
there is a risk of the machine icing up because the air is cooled
inside the dehumidifier until the water vapour condenses. The
lower the ambient temperature the lower the temperature inside
the dehumidifier and the closer to freezing you get.
If you do have an application
where there is little or no heating only ever buy a dehumidifier
with HOT GAS DEFROST. The following machines all have
hot gas defrost. The Mitsubishi's have a special low temperature
mode.
