These 2 rechargeable dehumidifiers each contain 300g of silica gel which will gather moisture from the surrounding area to protect your motor home/caravan etc from dampness. They each come complete with a hanging hook for easy placement in a suitable location & to enable recharging, one cable is supplied with a 230V 3 Amp plug. The easy to read indicator will show pink when the dehumidifier needs recharging & blue when the unit is ready to use simply plug in & recharge overnight. The units can last up to 3-4 months between recharging, depending on the volume of air & the amount of moisture in the atmosphere.
It should also be noted that silica gel crystal are not recharged by heat but by the water naturally moving from the damp crystals to drier air, the electrical heating only serves to speed this up. If you want to test this out then try drying clothes under a hot shower, no matter how much heat you introduce the clothes will stay wet or even get wetter. The point here is that silica gel dehumidifiers much be recharged in a dry environment, not in the damp place that you are trying to dry out. Think of them like a mop, they work in exactly the same way. After mopping up the floor you wouldn't squeeze the water out over the floor you just moppped up, would you? You'd squeeze it out somewhere you want the water moved to, like a sink or bucket. Also, when you want to dry the mop out you'd put it in a dry place, if you wanted to speed up the drying you'd place it in a WARM dry place. Silica gel crystals, (i.e. the 'glass' beads in these units) work in exactly the same way as a mop, they just 'mop
