The granules must have moisture in them. From what I understand the freezing breaks up the granules which would alter the characteristics of the flow and surface area of the scrubber. For diving purposes this translate into "work of breathing". I'm not sure how that would affect its use in a one atmosphere submersible which would not be as sensitive to CO2 buildup.<br>
