    I believe you are thinking of silica gel, it can be rejuvenated in
    the oven as you describe. The calcium chloride units like Dri-Z-Air
    pull the water out of the air and condense it on the crystals which
    then melt and the resulting liquid ends up in a collection pan below
    the crystals. Eventually you must replace the crystals as they have
    all melted away. They are able to remove lots more water from the air
    than an equivalent volume of silica gel but they do need to be
    replaced periodically.
