Primus Winter Gas can be used down to -22°C. As this is designed with Vapour Mesh- absorbent paper that has the capability to increase the surface for the evaporation process- therefore the liquid within the container changes to a gas much quicker. After 60 minutes of cooking, a Winter Gas cartridge is approximately 9 % more powerful than one without VapourMesh. After 120 minutes of use it delivers about 15 % more power.

Primus developed their Winter Gas to increase the performance of gas stoves at lower temperatures. Low temperatures reduce the pressure in the gas tank and worsen the evaporation of the liquid gas. This causes the stove to burn with less power or not at all, even though there may be gas left in the container. The main innovation behind the improved cold weather performance of Primus Winter Gas is VaporMesh. VaporMesh is a highly absorbent paper that sits around the entire inside of the container, thus increasing the surface area from which the liquid fuel evaporates to gaseous form. This helps keep the pressure higher which makes the stove burn better. The widened surface area also speeds up the liquid to gas transformation process, and it is this rapid transformation that determines the pressure inside the container. Fast process = high pressure.

Compared to conventional gas containers, this is what gives Winter Gas its reliable performance, even in cold conditions where it was previously impossible to use gas.

Smoother performance:
This is how Winter Gas maintains a smoother performance.
1. Expanded surface area = increased pressure:
The phase transition takes place from both paper and surface instead of only the surface of the container as with a conventional gas container. In this way, the surface area is expanded without requiring a larger container. This increases the pressure in the gas tank.
2. Reduced boiling time:
The VaporMesh paper and gas mixture increases the speed of the phase transition from liquid to gas. The burner receives more fuel, which means that the cooking time in really low temperatures will be shorter compared to other gas containers.
3. VaporMesh™:
A type of paper that coats the inside of the container and absorbs the gas in its liquid form. The effect of the VaporMesh paper intensifies as the fuel level decreases, and the gas gets a smoother performance over the lifespan of the gas tank.
4. Liquid gas:
The mixture of propane and isobutane gas is the same as that of Power Gas: around 20% propane and 80% isobutane.
