Primus 230 GM Winter Gas

Primus 230 GM Winter Gas

Gas that works down to -22 °C. The main innovation behind Primus Winter Gas coldweather performance is the VaporMesh, a highly absorbent paper inside the canister that keeps the pressure higher, making the stove run better. The vapor mesh increases the surface area, which the liquid fuel can evaporate into a gas state. The increased surface makes the change from liquid to gas faster and the speed of this process is what determines the pressure inside the canister. Compared to conventional canisters, Winter Gas can work in conditions where it was previously hard to operate.

• Gas that works down to -22 °C

• Larger surface - increased pressure: The innovative addition of the vapor mesh widens the available surface area instead of relying on just the surface of gas. That means a higher pressure and more available fuel

• Vapor mesh - The effect of the vapor mesh increases as the fuel level decreases

• Liquid gas - The mixture of Propane/Isobutane is the same as for Power approximately 20% Propane and 80% Isobutane

• Reduced boiling time - Thanks to the vapor mesh-paper and the gas blend the phase transition from liquid to gas is faster. The burner receives more fuel, which means that the boiling time in low temperatures becomes shorter compared to other gas canisters
