Dehumidifier for the engine bay

[matizado02]

Hi All,

I’m planing to install a permanent marine grade desiccant dehumidifier in the engine bay to reduce moisture and corrosion. It will run 24/7.

Do you have any expirience on this? Is this a good idea? any dowsides?

Many thanks in advance.

Ozone

Be sure the unit does not put out ozone, I know some have an ion feature that does. I was told that ozone can cause issues with rubber hoses and gaskets breaking down prematurely.

Hi John,

My boat is in the mediterranean sea in Spain. In that area the coldest temperature you may get in the hardest part of the winter is 45º F. The rest of the year is very warm. The climate is very humid as well.

That is why I was more incline for a Dehumifier (as the one described) rather than a heater.

Does this make sense? the cost of this toy is arounf 550$ so I want to be sure the investment is worth it and fit for the purpose.

Many thanks

If your area gets at all cold I’d go with those heaters mentioned by Rob because you get the same benefit to cutting down moisture and keeps it all warm.

Looks like a high quality unit,  BUT how come a simple question most would want to know  cannot be easily found in what I was able to read  (or maybe I am just stupid)..

Actual   POWER CONSUMPTIOM  in WATTS   ( regardless of voltage) when the unit is running ?

Indeed, this is it.

I herewith send you the link.

Stainless steel construction and the moisture being removed by venting are two of the main things.

So what is a marine grade dehumidifier?

I have been around dehumidifiers but not marine grade.   Something special?

Is it a replaceable dessicant type that you have to change every so often  or is  it  an automatic drying type that dries the dessicant when the dessicant reaches a certain moisture level. 

 

Just curious.

You may need to close the engine room air vents to avoid trying to dry out the entire world.

Rob,

Many thanks for you reply.

No personal experience but I have read about them and don’t see any down sides if setup right.  An oil pan heater does more for the engines themselves such as aiding cold starts and startup smoke mitigation but the dehu has many benefits as well.
