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 Summer Gas is a mixture of propane and butane and is optimised for summer conditions with temperatures between 15 °C and 40 °C. At really hot temperatures, other gas mixtures may be too powerful, meaning reduced efficiency and increased fuel consumption. There is no such risk with this gas mixture.
