Dehumidifiers; Boats are wet and especially when they are buttoned up in rainy and cold damp conditions. Because if this we are always interested in dehumidifiers and when the Space dryer from H20ut came to our attention we had to get one.
H2Out Space Dryers come in several sizes but they all are cylindrical stainless containers, containing Desiccant. The space dryer is simply placed in the area in need. The space dryer goes to work immediately and will last for some time. Once the Desiccant has reached its capacity it turns pink. No need to worry as the Desiccant is rechargeable, by placing the canister in an oven and when it turns blue again its fully recharged. The Desiccant is nontoxic, and noncorrosive.
Testing the HD309 Space Dryer
The HD309 space dryer has a coverage area of 800 cu ft. I placed the space dryer in a J/24 which has a small cabin of around 350 cu feet.
The dryer worked very well. The air after a few days was very dry and there was no condensation on the underside of the deck. Previously to the Space dryer there was condensation drops hanging from the underside of the deck due to wild fluctuations in outside temperature. The SD309 is the most popular of the space savers, but I think too big for the J/24 cabin volume. Even after 2 weeks the space dryer was not even showing any signs of being at capacity, so there was no need to reactivate.
The conclusion and our view of the Space Dryer is that the small portable rechargeable cylinders work very well and are suitable for placing in several places onboard to keep condensation down.
