MSR WindBurner Group Stove System
The WindBurner range has been extended for 2018 to include a new remote canister stove and various pots and pans to go with it. Richard Prideaux cooks up a review...
Multi award-winning Primus Winter Gas, with its innovative vapour mesh, improves the performance of LP gas cartridges at temperatures as low as -22°C. A selection of different brands of LPgas cartridges went head-to-head in temperatures of -8°C as highlighted in this video with Primus Winter Gas showing an outstanding performance in low temperatures when only ¼ full. Usually pressure would be really low at this point and performance unreliable.
The test, undertaken by Strong Roots Outdoors, pitched four types of LPgas against each other at Manchester's indoor ski & snowboarding centre, The Chill Factore (-8°C was as low as the location allowed). On test were: Primus Winter Gas; Primus Power Gas; Go Systems PowerSource and JetBoil's JetPower. Three tests were run: Cartridges as new with no fuel used before the test; Cartridges where 50% of the fuel by weight had been used before the test; Cartridges where 75% of the fuel by weight had been used before the test to leave just 25% remaining. All stoves and pots were the same models, brand new and each pot was filled with ½ litre of water at the same temperature.
The results of the test were as follows and the video of the test can be viewed below:
At full capacity all four performed well, boiling water between 3:50 min and 4:40 min.
At 50% capacity the GoSystems cartridge failed to bring the water to boil even after 8 minutes, whereas the other three took between an admirable 4:50 min and 5:15 min.
At just 25% full the JetBoil failed to bring the water to a boil even after 12 minutes. The Primus Power Gas took 10:20 min but the Primus Winter Gas performed fantastically well and took just 6:40 min.
Primus Winter Gas contains a unique innovation inside the cartridge: Vapour Mesh. Vapour Mesh is made from absorbent paper and increases the surface for the evaporation process, enabling LP gas to change phase from liquid to gas much easier and quicker making the Winter Gas deliver better performance than other cartridges in temperatures down to -22°C.
