On the market there are 2 types of dehumidifier ... COMPRESSOR AND DESICCANT ... so which one should i buy ?
Here at yachtmail we have sold both types of dehumidifier
They work by creating a cold surface and when the warm damp air touches the cold surface condensation forms and the water is removed from the air. These type of dehumidifiers only work when the temperature is at a minimum of 10'c so this means that the dehumidifier will spend a lots of time defrosting itself.
One benefit of a desiccant dehumidifiers is that they can remove large amounts of moisture from the air at one time . This is why they agree great for boats and camper vans as the temperature often drops very low and have a high humidity level.
So this is the answer to why you should buy a desiccant dehumdifier over a compressor..
