Marinising an evakool fridge /freezer

[89GQ]

Bought a 60 litre Evakool Fridge/freezer at the adelaide camping show yesterday, The sales man said you can have the motor/compressor marinised for $40, What the hell is that? anyone know? is it sprayed with something etc.Cheers for any help! PS he said its done if ya fridge is in a boat!!!!!

I would imagine that it would be a Protective Coating so that Sea Water would not damage Motor & Compressor

Marinised (also marinized) is when products have been specifically designed, redesigned or tested for use and long term survival in the harsh marine environment. This is done by many manufacturing industries worldwide including many military organisations (especially navies).

There are three main factors that need to be considered for a product to be truly marinised.
1. Corrosion
2. Vibration
3. A constantly changing attitude of the vessel. Similar to aircraft attitude

These three factors are a constant in the marine environment. Even on a dead calm day all three factors will still apply. This includes non salt water marine.

Some examples.

Marinised Electronics are electronics that use one or more of the following protection methods. In most cases more than one method is used.
1. Coated by a spray or dipping to protect from salt air and water
2. Fully encapsulated in some form of resin or gel.
3. Protected from Vibrations by specialised mounting of internal parts.
4. Special corrosion resistant solder and corrosion resistant metals are used

Marinised metals include some of the following examples.
1. Metals made up of alloys that do not corrode or resist corrosion. Ie. 316 marine grade Stainless steel.
2. Metals that have been electroplated or dipped in a corrosion resistant material. Ie. Galvanised steel.
3. Metals that are painted with special anti rust or anti corrosion coatings.
4. Naturally resistant metals such as Brass are also considered marinised if manufactured to a high quality without impurities that corrode.
5. Plastic coated metals

Marinised Batteries are usually Gel battery or sealed maintenance free battery.
Not using Marinised batteries in salt water can be deadly in an enclosed environment for many reasons.
1. Sulfuric acid and salt water are a dangerous combination. Mixing the two creates deadly chlorine gas. Therefore you must use a maintenance free sealed battery that is valve regulated.
2. The battery must have stronger plates and separators to compensate for constant vibrations and for impacts caused by large waves hitting the hull. If a standard battery is used and the plates collapse it can cause a short and electrical fire or explosion.
3. A marine battery must be capable of working at any angle due to the constant changing attitude of the vessel it is mounted in. Gel VRLA batteries are best for this purpose.

I would have to agree with Bob, sounds like salt environment proofing. Worth $40 if you ask me. Go for it

Thanks guys,Bloody quick responces! amazing, I'me never using google again! LOL. The fridge wont be in a boat but will be by the ocean alot where its windy and sand and salt spray go everywhere. So Yeh will check it out. Thanks again fellas. Jeff

Now that is quite an answer LOL

Dkuck should consider being our tech adviser,well done my man

Google is my friend

What I don't know gets googled. This is a regular occurance. lol

[gec]

And I thought this thread was going to tell me how to add flavour to my fridge.

Hahahah, when I first saw the subject line I thought the same........

[89GQ]

So any one know of any spray cans etc. of the protective coating?
