The Summer Gas Cassette by PRIMUS is equipped with a self-sealing, safety valves and bayonet joint and contents 220g Butane.
At temperatures above +15° C, conventional gas mixtures can "over-power" many cookers. When the regulator is fully open, more gas flows out than can be burnt clean because of the high pressure. The efficiency decreases and you consume more fuel than necessary. The Summer Gas by PRIMUS has been optimized for temperatures from +15° C to +40° C. It ensures the best possible efficiency in the heat.
