Fuel Canister Tray (for cold weather) by walter

Last crawled date: 3 years ago

Fuel canister tray to keep isobutane blend canisters working in cold weather. Fill the tray with water when in use, this should keep the canister warm enough to vaporize the isobutane as long as the water doesn't freeze.
If you've tried to use gas canisters in the cold, you've probably noticed that they don't work well. This is usually because the fuel is too cold to vaporize. This problem gets worse as the canister is used (the vaporization cools the canister) and as the fuel level gets low (there may be less propane in the mix.
The tray also works well to hold the canister in place when packed inside a pot of similar diameter. The raised feet help with stability on rocky surfaces.
