Dehumidifier

SCANAIR dehumidifier removes moisture from the air, thus lowering the humidity. It does this by condensing water onto a cold surface. This is a principle that we have all experienced. When you have an ice cold drink on a hot day, you notice water sweating on the outside of the glass. This is exactly how Scanair dehumidifier’s work, with a fewer minor differences to improve the effectiveness. A fan is used to speed up the process. It blows warm air onto cold metal coils, and the resulting water drips into a bucket. The resulting cold air is then passed over warm coils to bring it back to room temperature. Air conditioners work in the same way, but they do not reheat the air before returning it to the room.

Scanair Heat pump dehumidifiers extract water from the air by using a heat pump that is similar to an air conditioner. First, a fan pulls the indoor air across a very cold coil, which causes the moisture to condense. The droplets drip into a bucket inside the unit. The dry air is warmed by a second, heated coil and exhausted at room temperature. These dehumidifiers are considered among the most effective.

Scanair produce various types of dehumidifier and specifications as per customer requirements. Refrigeration-based dehumidification systems are more economical than desiccants at high temperatures and high moisture levels. In general, mechanical refrigeration systems will come down up to 40% RH. Desiccant-based systems are more economical than refrigeration systems at lower temperatures and lower moisture levels. Typically, a desiccant dehumidification system is utilized for applications below 40% RH down to 1% RH. Thus, in many applications, a DX or chilled water pre- cooling coil is mounted directly at the dehumidifier inlet. This design allows for removal of much of the initial heat and moisture prior to entering the dehumidifier where the moisture is reduced even further. Chemical absorbent dehumidifiers work best in warm climates. They use a chemical drying agent, or desiccant, on a heat exchange wheel to absorb water molecules from the air. Damp air is sent outside via vents. Desiccant dehumidifiers use a lot of energy. They are more commonly used by industries than homeowners.
