Based on the unit construction and their installation procedures, dehumidifier units can be broadly categorized into the following types.
Wall mounted dehumidifiers: Wall mounted dehumidifiers are specifically designed to be mounted on the wall, in contrast to other units which are either portable or floor standing.
Ducted dehumidifiers: Duct mount dehumidifiers can be integrated with existing HVAC systems for a more centralized and distributed airflow of dehumidified air across the entire area, allowing for quick and efficient humidity removal from a larger area than the immediate vicinity.
Ceiling mount dehumidifier: Unlike other traditional ductable or freestanding units, ceiling mount dehumidifiers are usually mounted on the ceiling of rooms using the help of additional wall brackets and are an ideal solution for use in spaces where limited floor space is a constraint.
Portable dehumidifiers: These are usually small to moderate capacity units that offer enhanced mobility for transportation from one place to another across the entire floor space without putting in much manual effort.
Basement dehumidifiers: Basements put forward multiple unique and unpredictable challenges due to their damp environment, which have high humidity levels, backed by redacted supply of fresh airflow. These units need to have a moderately higher extraction capacity and are sturdy and constructed to avoid corrosion to the unit.
Compressor dehumidifier: These systems leverage a refrigeration process for effective moisture management. They work by drawing in moist air, passing the air over a series of evaporator coils where the moisture gets condensed to water droplets, and the dry air is reheated back before releasing into the surrounding.
Silica gel dehumidifier: Unlike compressor-based units, silica gel dehumidifiers are categorized under desiccant units. Silica gel, due to its high affinity towards water, absorbs the water content present in the air, and leads to efficient humidity removal.
