(5) - Kontrol Krystals Dehumidifier Replacement Crystals 500g (5)

Combats damp condensation and musty odours. Ideal for caravans, boats, utility rooms, kitchens, bathrooms, wardrobes and cupboards. How They Work: Kontrol Crystals Anhydrous flakes of calcium chloride Ca CI have a high affinity to water and readily attract excess humidity from the air by a simple chemical process. When used in a moisture trap the krystals begin to coagulate sometimes developing a discoloured crust and eventually after a few weeks and depending oon levels of humidity/dampness liquid will begin to collect in the base of the moisture trap. Kontrol crystals will continue to function effectively for up to 2-3 months after exposure to the surrounding air. For optimum results place the moisture trap into areas where there is a damp or moisture problem replacing the krystals when the process is complete.
