Solenco Mini Dehumidifier – E-333 When it has absorbed all of the moisture the display on the front of the unit will change colour from yellow to green. It is at this point that you remove it from the space and plug it into the mains using the power lead that was supplied in the box. This activates a heating plate in the centre of the cassette which warms the silica gel up to release the moisture and regenerate the gel ready to be used again. This process can be repeated thousands of times. Packaging Dimension (color box) : 16.5 x 13 x 4.5 cm Absorbs excess moisture in small areas (drawers, storage boxes, cupboards, wardrobes, bookshelves, and bathrooms). Non-toxic and completely safe. No batteries or power required in operation. It is reusable after recharging – When the indicator window turns green, simply charge the unit by plugging the unit into a standard socket. When the drying process is complete, the indicator window will turn yellow and the unit is ready to use again. Shipping Info Standard Shipping Free Shipping We offer free shipping on orders over $30.
