ARB fridges
Thinking of getting an ARB fridge, but just wondered how long they stay cool for if there is no power going into them - ie I camp up for a couple of days, and don't have electric hook up or want to sit with the engine running (and also don't have a split charge system with leisure battery).

I know it will depend on factors like outside temperature, and number of times you access the fridge, but a rough idea would be useful

Hi Strang,

once cold and not opened they will stay cool for 5-6 hours each time you open will dramatically reduce this.

maybe get a liesure battery on it's own fully charged and take with you this should keep it running for a couple of days easily something liek a Oddessey PC1850 would be sufficient.

regards

I have a 47 litre ARB fridge. It's excellent, I don't have a split charge and can leave it 3 days no issues. Thumbs Up

The ARB 47 litre fridge is a good fridge Thumbs Up

How long will it keep cool with no power to it?

It is difficult to answer really, all depends on conditions etc, however there are ways of keeping it cooler longer.

Keep it out of the sun, increase external insulation, possibly using a solar blanket to reflect sunshine.

Fill the fridge and ensure fridge/contents are at required temperature before disconnecting power.

Take some freezer blocks or similar at -10C or less, with you and put them in fridge. You could use frozen carton drinks as well.

I'd think if you can afford the fridge, you can afford a duel battery and forget about worrying or fluffing around the fridge. Just spend the coin you won't be sorry.
Your question is very hard to answer with any predictability for reasons already mentioned. There are so many variables and if you like me at all camping, I'm constantly replacing a hot beer as I pull a cold one so the fridge tends to cycle every couple hours at 1 deg.

You can go a step further and solar the thing for 200 pound off ebay. I bought so cheap the Chinese didn't even put a sticker on my 120w panel. Link it to a MMPT charger and basically forget about where you're battery is at. That was 6 months ago with the set up permanently on the daily driver. It's a nice feeling when your fridge is cycling and the battery is full at the same time. The beer is icy cold and the wife and kids are happy.

Thanks for bringing this back up - I was actually quite surprised how 'warm' the fridge got once power was removed on my recent trip around europe. What I did find was that it kept cooler when it was full, so not just cooling an empty space.

I think the second battery is probably the way to go - I guess a 'leisure' one would to the job? Space is always the issue with a 90 though...... Euro-Leafing to infinity and beyond.....

Is the battery under the seat in a 90? My auxiliary lives next to the cranker. I have squeezed a 105Am/h in there but I also changed the direction of the cranker and had a base made to support it. But we like to sit for several days as well. I have a mate with 2 yellow top 55am/h Optima batteries in there as crankers and aux, it seems to work well.
If you move daily than the aux batter does not have to be big. Alternatively before I got the solar, I'd start and idle the car for 20 minutes each day to keep the battery strong and topped up. Don't let you batty go below 12V statuary (not under load) otherwise you'll be prematurely killing it.
I like the permanent set up, but one of those portable battery boxes may suit, but like you say space it at a premium in a 90. For me though, a cold working fringe is premium. An easy choice.

My wife shat her self when I told her the bill of the fridge and battery set up, but that first cold wine and weekend of no food floating around n cold water, all was forgotten. It is possible can get 12 days of cryo-vacked meat, veggies, and dairy for a family of 4 into our 47lt. Plus a litre of milk, bottle of wine, and keep me in cold beers at a steady controlled rate.

Nice Vincent.
Waiting for a CFX40 myself. Will be put to use as my daily fridge and I should be able to plug it in like a Prius when I'm parked on the driveway. The solar panels look like a smart addition to it all, but I'm not sure if the wife would agree on that. Ah well, as if I EVER discuss any mods with her... Cool

all mods are related to safety for her and the kids, thereafter convenience to her and the kids, you...come last. Same principals for everything really

The more free space (air), the quicker it will loose it's cold. Make sure it's filled up as much as possible, fill it up with some water bottles and get them cold before turning it off.
Solar blankets etc may help a bit as well, though I don't think it's a game changer.
Open it up as little as possible and as short as possible, so organise you fridge with this purpose and plan your actions.

All quite logical really.

Thanks.
The solar panels are almost below the edging of the roofrack and almost unvisible, unless you stand on a ladder. Wink Cheers, Vincent
