Description

Power Gas is our best-selling gas and is a mixture of propane and isobutane. A good all-round gas that is the perfect start with when cooking outdoors. Power Gas works best during the three warmest seasons of the year, but even when the temperature drops below zero, the gas provides enough pressure for your stove. Its versatility therefore makes it suitable for most adventures, even where the weather conditions and temperature are uncertain and varied. The pressure inside a gas container is high, so the gas is stored in liquid form. When you turn the knob, the pressure in the container drops and the liquid evaporates. When the vapour is ignited, you get a good flame to boil water or cook on. The conversion from liquid to gas requires energy, which is taken from the fuel, the container and the ambient environment. This causes the container to become cold (it can even form frost on the outside!). Different gases have different boiling points. The lower the boiling point, the higher the pressure in the container at a certain temperature, which leads to higher output on the stove. Propane has the lowest boiling point, followed by isobutane and then butane. At low temperatures, you want a mixture of gases that have a low boiling point as this results in better output on the stove. This is the reason behind the mixture of propane and isobutane in our Power Gas and Winter Gas. At higher outdoor temperatures, you want a mixture of gases with a higher boiling point instead, which is why we have butane instead of isobutane in our Summer Gas. Excessive pressure in the container causes the flame to become too strong. This makes the stove less fuel efficient and can also be dangerous, as the container is not designed for excessive pressure.
