Low Temperature Dehumidifier - For Use in Temperatures Below 15 Degrees CelsiusA low temperature dehumidifier is a dehumidifier designed especially for use in temperatures below 15 degrees Celsius, or 59 degrees Fahrenheit. Dehumidifiers work by cooling the air to the dew point to convert water vapor back to liquid, which can then be removed from the room.
The solution is to use a low temperature dehumidifier, which is different from a typical compressor based dehumidifier. This type of dehumidifier basically takes one of two forms. One is a compressor-based unit that is equipped with a hot gas defrost feature designed for low temperatures. The hot gas defrost prevents the compressor from icing up and allows it to continue to operate even in lower temperatures. Mitsubishi makes dehumidifiers with hot gas defrost as well as an auto-restart function that will turn the unit back on after a power failure, so they can be left unattended. The other option is to use an absorption based dehumidifier, which contains no compressor and can therefore operate at any temperature. Typical applications for a low temperature dehumidifier include any place that is not normally heated, but is prone to moisture. A summer home that is closed up all winter with the heat turned off is a prime example of a place where this type of dehumidifier may be needed. With no heat all winter, there is nothing to stop moisture from accumulating and causing devastating damage to your house. A dehumidifier that is capable of operating at low temperatures can keep moisture under control while the home is vacant and keep it in pristine condition until the owner returns. Store owners typically turn the heat off at night when the store is closed, and temperatures can drop below what is standard for a regular dehumidifier, especially during the winter. Garages, outdoor storage areas, boats and recreational vehicles are other places that would benefit from the use of a low temperature dehumidifier. An absorption based unit will extract the same amount of water no matter what the temperature is, which makes them more efficient at low temperatures than compressor based models. X-Dry and Delonghi both make absorption based dehumidifiers capable of extracting from six to ten litres of water per day at any temperature. The absence of a compressor makes these units lighter and quieter as well as less expensive. The X-Dry features auto-restart, while Delonghi does not, which is an important consideration if you are planning to leave the unit unattended for a long period of time. A low temperature dehumidifier is an investment that can keep your valuable possessions safe from moisture damage while they are in storage, and keep your summer home dry and mold-free over the winter while you are absent.
