Winter Gas

Date: 2018-09-30

Everybody who has used a gas cartridge stove in cold conditions knows this: the lower the temperature, the poorer the performance of the stove. In cold conditions the cartridge pressure decreases under use making the stove run with less power or not at all. Even though the cartridge might have fuel left in it. Why? Liquefied gas doesn´t evaporate properly the colder it gets.

The main innovation behind PRIMUS Winter Gas™ cold weather performance is the Vapor Mesh™ a highly absorbent paper inside the cartridge that will keep the pressure higher making the stove run better. Vapor Mesh™ increases the surface on which the liquid fuel can evaporate into 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 cartridge. Compared to conventional cartridges this makes it work in conditions when it was previously hard to use gas fuels.

PRIMUS Winter Gas works down to minus 22° Celsius without poorer performance. The cartridges are available in two sizes:

230 g

450 g
