Pod ventilation

This is what you want.

Get it cut to the thickness you want (frame width) and then cut to suit.
Tough as nails. Light as a feather. And will make a huge difference.

Does it breathe much?

Doesn't need to. Closed cell, so water / moisturiser resistant and also has a flame retardant in it so won't catch fire.

But won't allow any ventilation then?

Greetings El Presidente,

Fitting a scupper vent up high is a common practice on caravans to pressurise the inside to prevent dust getting in. Works well provided you are not driving in someone else’s dust cloud or in a dust storm. However I doubt that a vent like this would be of much use in keeping fridge temps down as what you are looking for is air circulation rather than pressurisation. It would require a second vent to allow air out, bringing with it more dust problems I’d guess.

Maybe putting more air in to keep fridge temps down is not the solution? To date I have not had any problem with fridge & freezer temps in my pod.

Just some thoughts in no particular order:

Is the wiring to the fridge heavy enough? Measure the voltage at the fridge end, if noticeably different to at the battery increase cable size.
Is there always good air space around the inlet & outlet vents of the compressor?
Is the warmer outlet air directed in such a way that it can’t be sucked back into the inlet - baffles may help.
Extra insulation on the fridge would help (helps the loss of cold from inside rather than addition of heat from outside).
Are you pre-cooling the fridge contents?
Do you take much notice of ‘fridge management’ - i.e. restrict how often it is opened & keep open times to a minimum?

Re spinning vents on the roof. (like on dog trailers). They are intended to take out hot air as opposed to scupper vents intended to pressurise, so may be helpful, but I’d look at these other things first. The ventilation would help prevent condensation when sleeping in the pod, but I have no idea how or if they deal with driving in rain.

Also used two of these over the cabin section of my troopy to
pressurize it and keep out the dust, worked a treat, IMO.
I wouldnt be putting those shark gill vents anywhere they let in rain and dust,
What about a small exhaust fan when on the move, just a thought

Ow no. I was meaning the product more as insulation to keep temps down. As mentioned above you want ain air tight box to keep dust and that out.
So the foam will insulate the pod. Keeping it cooler longer.

You could buy 20mm polystyrene sheets for that, did that on my other trailer,
very cool in direct sun but I had a solar panel on the roof creating a tropical roof,
allowing air flow

My troopy had air compensators on the rear qrt panel , helped when closing a door.
IF you look closely at one they have a rubber flap on the back to stop weather and dust
yet still breathe,
These are better than a whirly no working parts

Thanks. That's what I was looking for.

It'll be fantastic when I troll the highways and gravel verges!! lol

I keep forgetting my fridge is 95lts and needs a lot of cool air.

Thanks everybody. Keep those comments coming if you have any.
