Long Lasting

These Kontrol Crystals work day and night, summer and winter with no power source required to draw moisture and damp in caravan interiors, boats or around the home.

One 500g is capable of absorbing up to 1 litre of moisture, the crystals remain active as a moisture attractant for up to 2-3 months after exposure to air.

How Damp Crystals Work

Dehumidifier crystals are manufactured from Calcium Chloride which has a naturally occuring affinity to water and attracts excess humidity from the air around it by this simple, naturally occuring chemical process. When Calcium Chloride crystals are used within a moisture trap construction, they begin to coagulate as they draw in moisture; and eventually after a few weeks expel the water into the base "moisture trap" of the unit.
