I guess the APG won't have the microregulator at that price, so it's going to be poor in cold.
Just read the comparison at break.
What I thought.
But, putting canister in a freezer for an hour is going to reduce the effectiveness of any cart top stove without a regulator.
Inner only here without the corner, not sure on if its size you need though.
There is a nest without floor. Maybe make own floor shape required for it using Tyvek or Polcro?
Freezing the canister down to -10C is likely to stop all canister top stoves working efficiently ....FULL STOP.....regulator or not.
Highly likely that it will only be the propane gassing off while the isobutane just sits there.
Took a punt on a Jeebel Refilling Adapter, $8.39 a lot cheaper than others I’ve seen, looks well built.
Did a quick test today using 2 quarter full canisters, one canister had been in the freezer overnight, the ‘donor’ canister got stood in hot water for 15mins. Only took a minute to decant all but ~10g of gas out of the donor (no liquid left on the canister); seems like a practicable way of getting a usable canister out of a few ‘empties’.
I ordered one of these - saves borrowing my mates Gas Saver.
What I have found, is that carts filled with remnants are best used in warm weather, or indoors. I reckon remnants have a lot less than the 30% propane of a full can . Performance of remnant filled cans has been pretty poor compared to a new one. Majority butane refilled carts are ok in warmer conditions.
I think these devices are optimum for filling 100carts from new 250/ 500 carts . Saving money still.
I generally only use gas with the Kovea Spider in inverted mode (liquid) feed so expect the remnants in the canisters will still have a reasonable gas mix.
That would make a difference for sure. Be interested in how you get on.
I had 20 different partial carts from clearing out the Scout store...
@Whiteburn Do you have to freeze the can you are filling so that in liquid form gas can't get out? Just asking as I've just ordered one & wondering why you froze the one you filled.
Freezing the recipient canister reduces the pressure; heating the donor canister increases the pressure helping to push the liquid gas into the lower canister.
I was looking at one of these last year and scared the Jaysus outa me reading the horror stories on forums.... maybe I’m just scared of blowing myself up!!! Maybe I’ll give it a go now
Go for it, they are easy to use. Just be careful to note the final weight so you don't overfill.
The decanting of part used canisters is pretty straight forward & easy to predict the fill by weighing the canisters before hand.
Much trickery to decant from a full large canister, say a 400g, into an empty 100g canister; overfilling is an easy mistake .
I wouldn't burst during the filling BUT it may do if the canister was subsequently heated above the boiling point of the liquid gas.
As long as you know the actual weight of an empty cart or nominally "full" weight, then getting the safe maximum is easy enough. Weigh the refilled cartridge. If you've accidentally overfilled it, it's easy enough (and a darn good idea!) to empty a bit back out by turning it upside down and bleeding into another cartridge.
I have noted the full weight of my canisters on the base as they all differ slightly and also how many times they have been refilled. I will dispose of mine after 10-12 fills. All pretty arbitrary but I reckon I will have got good value from it by then.
Same as me but I dispose after 20 to 25 refills if there isn’t any exterior rust or dents evident. I cut my last one open just before I disposed of it to closely examine the valve and if it was corroded on the inside, which is wasn’t (as you would expect).
Got an Email to say Firemaple are having a sale atm, everything reduced.
Not sure how legit the price drops are, as sales seem to be perpetual...
117T @ £26.81 - pretty good IMHO.
PlanetX have got a few Firemaple bits in their sale
I think the BRS stove was about £20
