3 way fridge without gas

A complex question for me, but maybe a simple one for many members.

Can I run a 3 way fridge in my van, without having the gas hooked up? I'm thinking of ditching the gas altogether, as we'll just cook outside and I don't really want to have the gas if it's not really required.

You certainly can. I suggest that you just remove the gas bottle/s and tape over the ends of the pig tail/s. There may be a future owner who desires gas, it may be more difficult for you to unload the van if gas is not available.

Thanks for that.

To add a further curly one; I can still carry gas bottles with me right? How do I show that the gas is not operating through the van, but will be used in isolation outside of the van upon setting up camp? In other words, can the bottles still be trasnported in the current gas bottle holders, and still maintain a case that the gas is not being utlilesd through the van? Sorry for the wordiness.

Why do you not want to have gas connected to the van system? Is it because of the cost of gas compliance certificate? About the only time you would need a compliance certificate is at transfer of van registration.
You are able to carry 'loose' gas bottles so you could carry the bottles in the holders but not hooked up.

Hi Rod
Now that is an interesting question?
Is it simply a fear of gas or something more ,such as compliance
If it is a compliance issue then the whole gas system including appliances may not comply &would need to be removed, not just disconnected

Hi
Further to the above
If it is a compliance problem , it is most likely due to it being an imported unit
You could have far more serious compliance problems with the electrics & associated equipment

I agree with you Peter. It seems a very strange original question in that he doesn't seem to want to (or maybe can't) use gas or 240V on the van.

Thanks for all of that.

Firstly; my response to the 'strange' question part. I'm a newie and trying to get my head around everything. We figured that we like cooking outside, could save the $140 for the certification and any potential on-costs arising from the certification check. Following that, we had heard that gas could sometimes be dangerous. Once we heard that, we figured it wouldn't be too hard to go without the gas inside, and that we wouldn't really be missing out on all that much (providing we can still cook with loose gas bottles outside on a weber or a gas cooker, and that we can somehow run a fridge effectively).

As for the 240 volts, that will be all hooked up and being utilised.

Appreciate all of the help and advice!

I suppose you know if you don't have gas you will be only able to operate the fridge when hooked up to 240volts or on 12v when your tug engine is running.

Thanks Rod,

Yes but I can still run it off 12volts through an onboard auxiliary battery on the cvan but right, if not using the 240volt hookup?

Hi
Do not even THINK of running it on 12v when it is not connected to the tug &
tug engine is running
You will have a very sick battery within hours
It is 240v mains or nothing when you take away the gas

Right. Thanks oldtrack. See, I am learning a million miles a minute.

So, it's either a 3 way or a engel/waeco/ARB car fridge, that runs on 12 v through the tug while driving or 240v when we pull up.


Cheers

If you have sufficiently heavy cable from your alternator to your 3 way fridge then it will run efficiently whilst you are travelling and the motor is running. Only run your 3 way on gas or 240 V when stationary.

If you want to run a fridge from 12 V when you are camped it has to be a compressor fridge.

12v = dead battery (I mean pull up, go for lunch and then a walk along the beach, return 4 hours later, possible dead battery, they really suck it dry)

On 240V, awsome, but cheaper to buy a bar fridge and they use less power.

Gas, if not going anywhere too hot and keep level, by repute superb. I sold mine, tested gas on 34C days and I don't want my meat at 12C. And on 240v not much help, it was a Repco brand though so there is better quality, and they say an extraction fan would reduce the temperature on hot days significantly.

Even a small (90Lt) 3 way frindge on 12V draws aroudn 11 amps so it'll kill a battery pretty quickly.
When hooked to the car while driving the best the 12V from the car will do is maintain the fridge tempurature (If your lucky).
240V in parks etc works well and for camping without 240V stick with the LPG as it works really well.

There is a pretty good reason why 3 way fridges are destined for the same fate as the dynosurs.

The only reason you would have a 3 way fridge is because you want to run it on gas.

on 12 volts they are hopelessly inefficinet, especially if the wiring is not heavy enough......they are just as inefficient on 240V, but most people dont care because they are connected to mains and arent paying per KW hour.

Thewhole idear of heating something to cool it, it bazare to say the least but that is how 3 way fridges work..no wonder they are inefficient.

If you want to run on batteries you need a 12 volt compressor bassed fridge.

Batman's reply was a bit over the top.
You should just get it certified and see how you go with the gas after all it is not that expensive.
There are literally many thousands of vans running around this country using gas appliances when stopped without much trouble.

I have both a 12v compressor fridge in the tug and a three way fridge in the van and it operates quite OK up to temps go above 35% C then it struggles a bit. If your fridge is installed correctly then you will find it adequate except in real hot weather.

As said above on 12v from tug it will really only maintain temps and needs Gas or 240v to work properly.

So give it a go and see how you go.

I went on a weekend trip last month - 30 degrees days and took four sacrificial ice creams in the freezer of the camper 3 way - 12v while travelling and gas when stopped.

Lowest temp was -22 degrees and highest temp was -10 - had an ice cream on arrival, one after dinner on the two nights and one when I got back - all frozen solid.

So the old 3 ways can still work Ok.
