Hi, I just bought a used Dometic ACX40G coolbox and am wondering if anyone knows whether it would be possible to convert this to run off camping 907 bottles which we already have for our stove, instead of CP250 canisters, and if so how this could best be done? Cheers
Thanks for the suggestion. That info is for another model unfortunately. I have the acx40g which takes an inserted gas canister. Is this which I'd like to convert to a house and regulator with a 907 bottle, but not sure what kind of adaptor(s) might achieve this
OK I'm speculating to a degree here, as I don't have specific detailed knowledge of the cartridge (G) version of this fridge, but I do have the older version of the external gas cylinder type and a pal has an older version of your cartridge (G) model.
It may be more involved than simply finding some kind of adaptor (I'm not aware of any on the market!) to connect a Campingaz 907 (or any other external cylinder type) to the existing cartridge coupling. Firstly the disposable cartridges normally have no pressure regulation, so the burner gas jet is likely to be different (the entire burner may indeed be different) to one using a pressure regulated gas supply. Secondly the gas control valve (Off, Half, Full power on non-cartridge types - not sure about cartridge types) may be different and matched to the specific gas jet.
If you were thinking of cost saving, they do chomp through cartridges at a fair rate, and that's an expensive way of buying gas, Campingaz is damned expensive too, nearly twice as expensive as Calor last time I looked, so before jumping to a conversion, I'd be inclined to do some sums. On the label on the back of the fridge (no doubt in the instructions as well) there should be the gas consumption figure. Work out the hourly running cost on different sources of gas, think you may find using a 907 is not saving much if anything over cartridges. A Calor cylinder would be a different matter.
As I said, I am speculating to a degree, but have in the past converted natural gas hobs to run on LPG by swapping gas jets because of the differing supply pressures, and I have disassembled my fridge to fix a faulty gas burner, so have some knowledge of the innards.
A little more research may give you more definitive answers, but I suspect conversion is more than just finding an adaptor.
Certainly it would be possible to permanently re-plumb the internal gas piping rather than an adaptor and replace any necessary parts if they could be sourced and a qualified/competent person did the work, to bring it in line with the non-cartridge model, but not sure about cost effectiveness, probably cheaper to sell fridge for what it is and buy a external gas supply type.
Amazing family weekend with old steam engines, classic car displays, market stalls, and full catering and bar. And camping on site - Save £25 by booking in advance.
