How do dehumidifiers work?

Refrigerant dehumidifiers take in warm, moist air and pass it over cold pipes. This forces the water to condensate. Once the water has been extracted the air is warmed back up and returned to the room to collect more moisture.

Desiccant dehumidifiers draw in air and absorb the moisture from it using chemicals or absorbing material. The dry air is then blown back out and the cycle continues until the correct amount of moisture has been removed from the air. Desiccant dehumidifiers are better for use at lower temperatures.

Unlike with heat drying you don’t need ventilation because the dehumidifier is collecting the water from the air. Dehumidifiers work best in sealed areas as otherwise they are collecting moisture from the outside air too.

How does the Arxell Drying System enhance the process?

The room does not need to be sealed because the Arxell system creates a micro-climate between the wet surface and the units.

The air of low relative humidity is directed straight to the wet surface. This makes drying much more efficient as the moisture is taken from the wet area rather than the whole room.

The air is evenly dispersed across the surface so that the area dries at the same rate. This can be very beneficial when drying out sensitive materials as it prevents patchy drying.

In-house tests have shown that using the Arxell Drying System reduces drying times by up to two thirds compared to using a dehumidifier alone.
