A Dehumidifier is an appliance that lowers the level of humidity by removing excess moisture from the air. It works in reverse of a humidifier by removing the condensation on surfaces, typical of high humidity, by evaporation.
The types of Dehumidifiers available use different methods to remove moisture from the air. These include Refrigerant, Heated Rod, Rechargeable, Electronic, and Desiccant Dehumidifiers. One of our top choices for dehumidifiers are the Honeywell Dehumidifier range. They just seem to last.
If you attempt to run a regular dehumidifier at low temperatures, you risk seizing the machine. When the unit is run at a lower temperature than it is designed for, the cooling coils frost over. This affects the unit by causing the compressor to shut down. It then turns itself back on. However, the water is not removed from the air. If this occurs, the unit has to be turned off and allowed to defrost before it can be used again. Newer units get over this problem by being equipped with sensors that automatically turn the dehumidifier off if the coils begin to freeze.
If you have made the decision to buy an air dehumidifier, then ask yourself where and when the unit will be used the most. If your climate becomes cold for an extended period of time, and if you plan to use your unit in a semi outdoor setting, you will need to consider purchasing a low temperature dehumidifier. Knowing where and how you will use it will serve you best in your choice.
